The paint finish on the vehicle provides beauty, depth of color, gloss retention, and durability.

The best way to preserve the vehicle's finish is to keep it clean by washing it often with lukewarm or cold water.

Do not wash the vehicle in the direct rays of the sun. Use a car washing soap. Do not use strong soaps or chemical detergents. Be sure to rinse the vehicle well, removing all soap residue completely. GM-approved cleaning products can be obtained from your dealer. See Vehicle Care/Appearance Materials . Do not use cleaning agents that are petroleum based, or that contain acid or abrasives. All cleaning agents should be flushed promptly and not allowed to dry on the surface, or they could stain. Dry the finish with a soft, clean chamois or an all-cotton towel to avoid surface scratches and water spotting.

High pressure car washes may cause water to enter the vehicle.

The overall height, width, and underbody clearances of the HUMMER H2 are similar to current General Motors' full-size light duty trucks. This means a HUMMER H2 should fit in a standard car wash. But, if your vehicle has added accessories like roof-mounted lamps or a roof basket, it might not fit properly in a standard car wash.

Notice: Certain add-on accessories can change the dimensions of your vehicle. If you've added items to the outside of your vehicle, it might not fit properly in a standard car wash. Your vehicle and the car wash could be damaged. To help prevent damage, know how accessories have changed the dimensions of your vehicle and check with the car wash manager before entering a car wash.

Notice: If you drive your vehicle through an automatic car wash that does not have enough clearance for any roof-mounted accessories (such as off-road lamps or a roof basket) on your vehicle, you can damage your vehicle. To avoid damaging your vehicle in a car wash, remove any roof-mounted accessories if you can, and do not use an automatic car wash while roof-mounted accessories are on your vehicle. See Power Winch Platform and Off-Road Lamps for more information.
