Rocking Your Vehicle To Get It Out First, turn your steering wheel left and right. That will clear the area around your front wheels. If you have a four-wheel drive vehicle, shift into 4HI. Then shift back and forth between REVERSE (R) and a forward gear (or with a manual transmission, between FIRST (1) or SECOND ( 2 ) and REVERSE (R)), spinningthe wheels as little as possible. Release theaccelerator pedal while you shift, and press lightly on the accelerator pedal when the transmission is in gear. If that doesn't get you out aftera few tries, you may need to be towed out. Or, you can use your recovery hooks if your vehicle has them. If you do need to be towed out, see"Towing Your Vehicle" in the Index. Using the Recovery Hooks Your vehicle may be equipped with recovery hooks. The recovery hooks are provided at the front of your vehicle. You may need to use them if you're stuck off-road and need to be pulled to some place where you can continue driving. 5-36
