GMC Sierra Owners Manual

If the Vehicle Is Stuck
Driving and Operating / Driving Information / If the Vehicle Is Stuck

Slowly and cautiously spin the wheels to free the vehicle when stuck in sand, mud, ice, or snow.

See Rocking Your Vehicle to Get It Out later in this section.

If the vehicle has a traction system, it can often help to free a stuck vehicle. Refer to the vehicle's traction system in the Index. If stuck too severely for the traction system to free the vehicle, turn the traction system off and use the rocking method.

WARNING
If the vehicle's tires spin at high speed, they can explode, and you or others could be injured. The vehicle can overheat, causing an engine compartment fire or other damage. Spin the wheels as little as possible and avoid going above 55 km/h (35 mph).

For information about using tire chains on the vehicle, see Tire Chains on page 10‑77.

Rocking Your Vehicle to Get It Out

Turn the steering wheel left and right to clear the area around the front wheels. For four-wheel-drive vehicles, shift into Four-Wheel High.

For vehicles with StabiliTrak, turn the traction control part of the system off. Shift back and forth between R (Reverse) and a forward gear, spinning the wheels as little as possible. To prevent transmission wear, wait until the wheels stop spinning before shifting gears.

Release the accelerator pedal while shifting, and press lightly on the accelerator pedal when the transmission is in gear. Slowly spinning the wheels in the forward and reverse directions causes a rocking motion that could free the vehicle. If that does not get the vehicle out after a few tries, it might need to be towed out. Recovery hooks can be used, if the vehicle has them. If the vehicle does need to be towed out, see Towing the Vehicle on page 10‑96.

Recovery Hooks

WARNING
Never pull on recovery hooks from the side. The hooks could break and you and others could be injured. When using recovery hooks, always pull the vehicle straight out.

GMS Sierra: If the Vehicle Is Stuck. Notice: Never use recovery hooks to tow the vehicle. Your vehicle could be damaged and it would not be covered by warranty.

Notice: Never use recovery hooks to tow the vehicle. Your vehicle could be damaged and it would not be covered by warranty.

For vehicles with recovery hooks at the front of the vehicle, you can use them if you are stuck off-road and need to be pulled to some place where you can continue driving.
