Driving again. If the warning light reappears, turn the air suspension switch off and have the vehicle serviced by a dealer or qualified service technician. If the vehicle is loaded beyond the recommended maximum payload, the CK SUSP light may illuminate. To correct this condition, remove or redistribute the payload according to the recommended requirements and follow the procedure outlined above. AUTOMATIC TRANSMISSION OPERATION (IF EQUIPPED) Brake-shift interlock This vehicle is equipped with a brake-shift interlock feature that prevents the gearshift from being moved from P (Park) unless the brake pedal is depressed. If you cannot move the gearshift out of P (Park) with the brake pedal depressed: 1. Apply the parking brake, turn ignition key to LOCK, then remove the key. 2. Insert the key and turn it to OFF. Apply the brake pedal and shift to N (Neutral). 3. Start the vehicle. If it is necessary to use the above procedure to move the gearshift, it is possible that a fuse has blown or the vehicle's brakelamps are not operating properly. Refer to Fuses and relays in the Roadside emergencies chapter. Do not drive your vehicle until you verify that the brakelamps are working. If your vehicle gets stuck in mud or snow it may be rocked out by shifting from forward and reverse gears, stopping between shifts, in a steady pattern. Press lightly on the accelerator in each gear. Do not rock the vehicle for more than a few minutes. The transmission and tires may be damaged or the engine may overheat. Always set the parking brake fully and make sure the gearshift is latched in P (Park). Turn off the ignition whenever you leave your vehicle. 120
