H3
THE MIDSIZE H3. Proof positive that good things can come in small packages. Even if you are a HUMMER. Of course, to belong to the HUMMER family, you not only have to look the part, you also have to live up to the off-road reputation that the family made famous. We’re proud to say that the H3 does. Fully capable off-road. Totally comfortable on it. HUMMER 100,000-mile/5-year Transferable Powertrain Warranty*. OnStar** with 1-year safe and sound service plan. All standard.
* 2008 Models. Whichever comes first. See dealer for limited warranty details.
** Call 1-888-4ONSTAR (1-888-466-7827) or visit www.onstar.com for system limitations and details.
DETAILS
The H3 is designed to get you through the most off-road obstacles unscathed with its fully welded steel frame, 8.5 inches of ground clearance, and full undercarriage protection. The H3 is also particularly adept in water, being able to ford 24 inches at 5mph and 16 inches at 20 mph. And a 37.0° approach angle coupled with a 35.3° departure angle will help you get rid of most of your hang-ups.
Since the H3 was designed to handle extreme off-road conditions, it stands to reason that it’s surefooted on-road as well, but that didn’t stop our engineers from adding a few "just in case" features, you know, just in case. The swing gate is mounted with a full-sized spare, the standard OnStar comes with a 1-year Safe and Sound Service Plan,* and remote keyless entry with a panic button provides the driver with an heightened sense of security.
Powering the H3 is the Vortec® 3700 3.7L engine. It turns out 242 hp and 242 lb.-ft. of torque at 4600 rpm with either the 5-speed manual or the available 4-speed automatic transmission. Being both high-tech and lightweight, the Vortec® 3700 further brings to the H3 a perfect balance between performance and fuel economy.**
With options like 7 exterior colors, 6 interior choices, and a wide variety of individual accessories, you can be sure you’ll be able to create a HUMMER that is all your own.
** EPA estimated mpg 13-city/18 highways.
INNOVATION
VORTEC 3700
Breathing life into the H3 is the Vortec 3700 5-cylinder engine that generates an impressive 242 lb-ft of low-end torque at 4600 rpm and strikes a perfect balance between performance and fuel efficiency*. Being both high-tech and lightweight, this "smart engine" is highly durable, making it the perfect choice for the H3, allowing us to offer a HUMMER 100,000-mile/5-year Transferable Powertrain Warranty†, whichever comes first.
The Vortec 3700 is available with either a standard, smooth shifting five-speed manual transmission or a Hydra-Matic 4L60-E electronically controlled four-speed automatic transmission. The automatic transmission includes shift modes specific to the low-range operation, which, combined with speed-based throttle progressions, help optimize drivability in low-range off-highway conditions.
* EPA estimated mpg 14 city/18 highway.
† See your dealer for limited warranty details.
4 –Channel Anti-Lock Braking
The 4-Channel Anti-Lock Braking System (ABS), standard on the H3, allows you steering control even under extreme braking, without tire "lock up." The ABS in the H3 also adjusts to changing roads, helping you to come to a smooth, controlled stop on almost any surface. For example, after heavy rains a washboard type pattern can develop on dirt roads. The H3’s ABS is able to recognize this surface and react by preventing the ABS from continually repeating a cycle of applying and depressurizing the brakes.
DYNAMIC REAR BRAKE PROPORTIONING
Another integral part of this intelligent braking system is Dynamic Rear Brake Proportioning. This system modulates rear brake pressure and ensures that braking is balanced between both front and rear brakes. In English, that means the nose of the H3 won’t dive down while braking hard. And in any language, that means your passengers might not even notice what just happened.
And as is the case with all HUMMERS, there’s more.
STABILITRAK STABILITY ENHANCEMENT SYSTEM
The StabiliTrak Stability Enhancement System, standard on the H3, provides more precise, all-weather control by applying braking forces to help correct oversteer or understeer. This is particularly useful on slick surfaces or during emergency maneuvers, such as swerving to avoid an object in the road.
AIR BAGS
All H3s come standard with dual front air bags* that feature a Passenger Sensing System. This system decides whether to enable or suppress the front passenger air bags based on the passenger seated weight. The air bag is enabled when the system classifies the occupant as a larger adult and automatically turns off whenever the seat is unoccupied or if a smaller adult occupies it. In addition, the H3 has a number of child-based safety features like the LATCH system for anchoring child seats in the rear, rear door child locks, and "anti-pitch protection" for the power windows and sunroof.
Another key feature on the H3 are the standard head curtain side air bags* with roof line to belt rollover sensors. In the event of a moderate to severe side-impact collision, the head curtain side air bags inflate, providing added head-impact protection for the front and rear passengers sitting next to the doors.
*Always use safety belts and correct child restraints for your child’s age and size. Even in vehicles equipped with the Passenger Sensing System, children are safer when properly secured in the rear seat. Never place a rear-facing infant restraint in the front seat of any vehicle equipped with an active frontal air bag. See the vehicle Owner’s Manual and child safety seat instructions for more safety information.
ONSTAR
DRIVING CONFIDENCE
See how OnStar is giving drivers greater confidence on the road.
Standard for one year on HUMMER H3 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 H3’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 H3’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 H3, 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 H3’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 H3 while keeping your hands on the wheel and your eyes on the road.***
AND WITH YOUR NEW H3 YOU WILL RECEIVE THE ONSTAR® SAFE & SOUND SERVICE PLAN.

*OnStar acts as a link to emergency service providers. Visit www.onstar.com or call 1.888.4.ONSTAR (1.888.466.7827) for system limitations and details.
**Success varies with conditions.
***OnStar Hands-Free Calling requires a Hands-Free Calling enabled vehicle, existing OnStar service contract and prepaid minutes or enrollment in a shared minutes plan. Not available in certain markets. Calls may be made to the U.S. and Canada only.
FULL-TIME 4WD
Powered by an electronically controlled, fully integrated powertrain system, the H3 is a versatile full-time 4WD vehicle with full-function traction control.
The powertrain-integrated, 2-speed, electronically-controlled, full-time 4WD system enables you to go places even the most seasoned SUVs couldn’t dream of. By offering both high and low range, high for on-road and low for off-road, the H3 gives you more precise throttle control and more horsepower at slower speeds for times when you need it. This, coupled with the full-function, single-wheel traction control, allows the H3 to marry matchless off-road capability with outstanding fuel efficiency.*
*EPA estimated mpg 14 city/18 highway.
ON THE OUTSIDE

PROTECTION
With all this off-road capability, exterior protection is obviously imperative. To that end, the H3 boasts underbody protection that runs the entire length of the vehicle beginning with the thick, solid aluminum, front skidplate. This shield helps protect the frame and front suspension components from rock strikes and other hard hits. Also standard are three high-strength steel skid plates to help protect the oil pan, fuel tank and the transfer case.
An available Underbody Protection Package features two skidplates, providing enhanced protection for the transfer case and the transmission oil pan as well.
Also available is full-body Rocker Panel Protection designed to help protect the sides of the vehicle from even the meanest off-road threats.
With all these features, the H3 not only makes sure you can get your truck into the rough country, but also makes sure you have all the protection required to get back.

OFF-ROAD CAPABLE
The H3’s large tires, wide stance, and short front and rear overhangs combine not only to carve a distinctly HUMMER silhouette, but also to provide stability, outstanding ground clearance and enhanced rock-climbing capability. The skidplate provides vital underbody protection while off-roading. The large tires also enhance traction both on and off-road.
In short, the H3 is capable of…
GROUND CLEARANCE
Standard 32" tires: 8.5 in.
Optional 33" tires: 9.1 in.
Vertical scaling height: 16 in.
Side slope capability: 40%
Grade capability: 60%
WATER FORDING
16 in. at 20 mph
24 in. at 5 mph
ON THE INSIDE
INTERIOR
Get behind the wheel of the H3 and you’ll instantly feel like it was custom designed for you. From the rotary control switches to the individual gauge bezels to the soft touch caps on the control switches, you’ll notice everything is ergonomically organized, easy to use, and accessible.
In addition, you’ll find a host of subtler features that enhance your interior experience. Like the five standard assist handles that make entry easier and offer support in severe off-road terrain. The unique brushed finish on the driver information center adds a premium feel while the optional leather-appointed seating, automatic gear controls and chrome door handles combine to create class and richness. In other words, the interior plays the perfect foil to the H3’s tough exterior.
SEATING
The H3 features plush bucket seating that comfortably houses 5 adult comes in cloth or optional leather appointed seating.
All seating is finished with double-stitched "French" seams that further accentuate the premium European look. The front and back row seats also come with dual density foam and soft bolsters to provide additional comfort and support during severe off-road maneuvers. In addition, the back row seats have a 60/40 split that can be folded down to create 56.4 cubic feet of cargo space.*
The cloth interior is available in Ebony with Pewter seat inserts, Ebony with Red seat inserts or Ebony with Light Cashmere seat inserts.
The leather-appointed seating comes in Ebony with Pewter piping, Light Cashmere with Ebony piping (shown at left) or Ebony with Morocco-toned seat inserts and piping.
*Cargo and load capacity are limited by weight and distribution.
