INNOVATION

TRACTION CONTROL

Power is nothing without control. That’s why the H2 offers extraordinary control in the form of a 2-speed, electronically controlled, full-time 4WD system. Perhaps the most advanced system offered on a consumer vehicle. This system incorporates a stronger, improved transfer case, unique in that it offers 4 high lock and true 4 low lock ranges that make the H2 capable of adapting to all types of surfaces at the touch of a button.

Working in tandem with the 4WD to give you even more control over your H2 is an advance Traction Control System that’s peerless in the SUV category. Whether off-roading or simply on slippery road surfaces, TCS continually monitors the rotational speed of each wheel. If one wheel is spinning more than the others, TCS applies braking pressure to the spinning wheel to help it regain composure and transfers available torque to the wheels that have traction. Using this system, an H2 with three spinning wheels can still move forward, even on an upward grade of 10%.

OPERATIONAL MODES:

4 HI OPEN
for normal everyday driving on dry road surfaces, allowing the front and rear axles to move at different speeds with a 40/60 front to rear split.

4 HI LOCKED
for semi-slippery surfaces like snow, light sand, gravel or wet areas. This locks the front and rear axles together for additional traction and has a 50/50 front to rear power split.

4 LOW LOCKED
for severe off-pavement use. This locks the front and rear axles together and engages a reduction of the gear ratio to 2.64:1 for controlled rock and obstacle climbing. This mode also has 50/50 front to rear power split.

4 LOW LOCKED & REAR AXLE DIFFERENTIAL LOCKED
for optimal, slow-speed capability while climbing large rocks or steep grades, the rear differential locks the rear axle shafts together sending equal torque to both rear wheels.

NEUTRAL
is the 5th mode, which permits flat towing of the H2 behind another vehicle.

SUSPENSION

FRONT

The H2 uses an independent torsion bar front suspension which is excellent on-road and incorporates features that make it even more impressive off-road. High-strength monotube gas-charge shock absorbers, known for durability, grace the front suspensions of the H2. This system incorporates two rubber cushions called "jounce bumpers" which absorb jolts under normal off-road conditions.

As things get rougher and suspension travel increases, a frame-mounted urethane bumper prevents the suspension from hitting the frame. However, the shock absorbers themselves have integrated bump stop rings that slow the suspension’s travel before it needs to strike this final cushion.

In addition to a 4,000 lb. axle capacity, the front suspension has a large 36 mm diameter tubular front stabilizer bar, in conjunction with a standard tubular 30 mm diameter rear stabilizer bar, to help minimize body roll when cornering. The result is a smooth ride, with front-end control that adapts to changing terrain, both on- and off-road, that maximizes traction in all conditions.

REAR

The standard rear suspension on the H2 features a 5-link trailing arm, coil springs and a stabilizer bar. The spring rate is variable from a soft on-road rate, through a transitional rate, to a stiff off-road rate, which helps prevent bump and impact input forces from transmitting into the H2’s body.

Perhaps the most eyebrow raising aspect of he H2’s rear suspension is the solid rear axle. Consider this in the context of off-roading. Say you’re crossing a field strewn with boulders. As the back end of your truck rolls over a rock, independent suspension allows the rear tires to rise, but leaves the rear-end housing where it is, and subsequently vunerable to a rock strike. But the H2’s solid rear axle rises with the rear tires, lifting the rear so you can continue on your way without having felt a thing.

ONSTAR
DRIVING CONFIDENCE

See how OnStar is giving drivers greater confidence on the road.

Standard for one year on the HUMMER H2 is the state-of-the-art OnStar system. First and foremost, OnStar means safety. In an emergency, such as vehicle collision, your OnStar system can automatically notify your OnStar Advisor and provide your H2’s exact location. The OnStar Advisor can attempt to contact you to inquire whether you need assistance. Also, the OnStar Advisor can notify emergency services and send help to you.*

But, we hope that never happens. So we made sure OnStar would still be useful to you in a multitude of other ways. For example, if you ever make the unfortunate mistake of locking your keys inside your HUMMER, you can call the OnStar center and an Advisor can send a signal to unlock your doors remotely.** If your "check engine" light ever illuminates, or you suspect trouble, at the touch of a button on your H2’s rear-view mirror, your OnStar Advisor can help by running a diagnostic check of your engine, even while you’re still driving. Or, if you ever forget where you parked your H2, you can alert OnStar to activate your horn and lights to easily locate your truck.

In the event of theft, OnStar can also attempt to pinpoint your H2’s exact location in real time, aiding greatly in vehicle recovery.** Also, OnStar can help you stay connected with OnStar Hands-Free Calling, which allows you to make and receive hands-free calls in your H2 while keeping your hands on the wheel and your eyes on the road.***

AND WITH YOUR NEW H2 SUV YOU WILL RECEIVE THE ONSTAR® DIRECTIONS & CONNECTIONS SERVICE PLAN.

BRAKING SYSTEM

ABS

The 4-channel Anti-Lock Braking System (ABS), standard on the H2, allows enhanced steering control under extreme braking conditions, without tire “lock-up." An example of what makes this system so unique is found in the context of driving on gravel roads. After heavy rains, gravel can develop certain patterns. The H2’s brakes can recognize these surfaces and react accordingly. Bringing you to a controlled stop.

DYNAMIC REAR PROPORTIONING

Another example of the H2’s advanced braking ability is Dynamic Rear Proportioning. This system modulates the rear brake pressure as needed to ensure that braking is balanced between the rear and front brakes. Further, this helps balance wear and prevents the nose of the H2 from driving downward when braking hard. It’s specifically designed to work seamlessly all the time, without you ever being aware of it while sitting comfortably behind the wheel.

LEFT FOOT BRAKING

The 2008 H2 is engineered to be more responsive to "Left Foot Braking," a technique that allows drivers even better control of their H2 off-road. Usually Anti-Lock Brakes (ABS) and the Traction Control System (TCS) function independently despite sharing the same space. But in the 2008 H2, the engineers designed a system that allows brake operation (under light application) and TCS to work at the same time.

This is best seen in a rock crawling scenario where a driver, while in 4 low lock, can simultaneously use the right foot to control the throttle and the left foot to control the brake while TCS continues to manage torque across the axels. This allows the driver to precisely control the truck’s speed over rocks, while engine torque still gets to the wheels that have the best traction.

ON THE OUTSIDE

PROTECTION

BUMPERS

Like many other H2 components, the bumpers are unusually large and hefty. They also have a two-sectional design to help reduce weight while still providing optimum protection.

The front bumper also includes large, military-style retrieval loops. The rear bumper includes tow loops which can also serve as tie-downs and both bumpers have access holes for the hitch receivers which can be attached to the chassis. The front receiver accommodates a winch, which can be plugged in just like a trailer hitch. The front receiver, like the rear receiver, also accommodates a regular class 3-trailer hitch, providing additional flexibility by allowing you to nose a boat into a garage for example.

SKID PLATE

Nobody likes to resort to it, but sometimes a skid plate is the only language boulders understand.

That’s why you’ll find a 4 mm thick, stamped aluminum front engine shield that runs from the front bumper of the H2 right back to the transmission. It angles prominently at the front, with the H2 logo embossed just below the bumper. One-inch diameter tubular steel, ladder-type shield helps protect the transmission and the exhaust system’s two catalytic converters.

A third, high-tensile strength, galvanized steel shield helps protect the transfer case.

ROCKER PANEL PROTECTION

The rocker panels are large, standard, black painted steel tubes, running along each side of the vehicle to help protect its lower body and door panels against rocks and stumps. The high-strength structural pieces bolt right into the frame with heavy brackets and are designed to withstand off-road impacts from beneath or from side angles.

FRAME

To build a HUMMER, a strong foundation is a must. The H2 uses a welded ladder-type frame with full-length, box-section side rails and a 3-piece modular design consisting of front, middle and rear sections.

FRONT SECTION

The front section is hydro-formed, making it strong enough to support a 9,000 lb. winch in the integral receiver mount. This also allows you to affix a trailer hitch, so you can easily "nose" a trailer into a garage or parking space.

MID FRAME

The mid-section is a fabricated and welded, stamped-steel box segment that helps minimize vibrations for a smooth ride.

REAR FRAME

The hydro-formed, short rear section, reinforced to handle the weight of a fully loaded vehicle, comes with a standard, integral trailer hitch receiver certified to tow 8,200 lb. The end result is an immensely strong frame with a long wheelbase and a wide, balanced stance. When combined with full underbody and rocker panel protection you can get to almost anywhere and beyond and back.

ON THE INSIDE

INTERIOR

The H2’s newly refined interior seamlessly compliments its improved on-road performance. Once behind the wheel, you’ll encounter a host of new features designed to make driving a pleasure. The new instrument, door trim, and center infotainment panels are all organized, accessible and easy to use.

The Bose® performance-enhanced seven-speaker sound system comes standard on both the Base and Adventures series, while the Bose® 5.1 Cabin Surround Sound System comes standard on the H2 SUV Luxury. And there are even rear seat audio controls with headphone jacks that allow the 2nd row passengers to listen to separate audio sources. The sound systems are specifically tuned for the H2’s unique interior by the high-fidelity experts at Bose®.

SEATING

We paid special attention to the seats in the H2 as we did with everything else.

In the H2 you’ll find comfortable front seats with standard eight-way power adjustment and four-way lumbar adjustment. A standard memory feature for the driver’s seat allows two drivers to select and set their preferred positions. For additional comfort, the front seat safety belts are now mounted to the vehicles B-pillars and now include safety belt pretensioners.

Leather-trimmed seating surfaces are standard. With the sedona or ebony colored leather-trimmed seats, front occupants also get heated seat backs and cushions with three temperature settings, and second-row occupants get heated cushions.

The 60/40 split-folding second-row seats have high seat backs for maximum adult comfort. New, is an optional full third-row seat, allowing the H2 to comfortably accommodate seven.

CAPABILITIES

Though they may not come into play day-by-day, if and when they do, you’ll be glad your H2 is ready.

GROUND CLEARANCE

9.7" OF GROUND CLEARANCE ALLOWS THE H2 TO GRACEFULLY CLEAR OBSTACLES, BOTH ON AND OFF-ROAD.

WATER FORDING

THE H2 CAN FORD AN IMPRESSIVE 24" OF WATER AT 5 MPH.

AGILITY

THE H2 HAS AN APPROACH ANGLE OF 39.8°, DEPARTURE ANGLE OF 37.1° AND A BREAKOVER ANGLE OF 23.5°, ALL ALLOWING THE H2 TO PASS THROUGH DEEP DITCHES AND TRAVERSE LARGE DIRT MOUNDS WITHOUT SUFFERING FRONT- OR REAR-END DAMAGE.

TRAILERING

THE H2 HAS A TOWING CAPACITY OF 8,200 LB. ITS FULL-TIME 4WD TRANSFER CASE SENDS POWER TO THE FRONT AND REAR, ALLOWING THE H2 TO TOW EVEN IN THE TOUGHEST SITUATIONS.*

*Trailer tongue weight should be 10%-15% of total loaded trailer weight, up to 1,000 lb.  Do not exceed the maximum allowable tongue weight for your vehicle.  Gross Combination Weight Rating (GCWR), which is the total allowable weight of the completely loaded vehicle and trailer including any passengers, cargo, equipment and conversions, is 15,000 lb.  If you’ll be pulling a trailer that, when loaded, will weigh more than 5,000 lb., be sure to use a properly mounted, weight distributing hitch and sway control of the proper size.  If your trailer weighs more than 2,000 lb. loaded then it needs its own brakes, and they must be adequate.  Trailer weight ratings are calculated assuming a base vehicle, except for any option(s) necessary to achieve the rating, plus driver.  The weight of other optional equipment, passengers and cargo will reduce the maximum trailer weight your vehicle can tow.  See your HUMMER dealer for additional details.

BALANCE – GRADE CAPABILITY

THE H2 CAN SCALE A 60% GRADE.

BALANCE – SIDE SLOPE

THE H2 CAN TRAVERSE A 40% SIDE SLOPE.

BALANCE – VERTICAL SCALING

THE H2 CAN CLIMB A 16" VERTICAL WALL
STEP CLIMBING IS BEST DONE BY APPROACHING THE STEP FROM AN ANGLE, RATHER THAN STRAIGHT ON.
