towing JEEP WRANGLER UNLIMITED 2014 User Guide

TOWING A DISABLED VEHICLE • The manufacturer requires towing your vehicle with all four wheels OFF the ground
using a flatbed.
CAUTION!Towing this vehicle using any other method could result in extensive damage to the
transfer case and/or transmission.
FREEING A STUCK VEHICLE • If your vehicle becomes stuck in mud, sand or snow, it can often be moved by a
rocking motion. Turn your steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between DRIVE/1st gear and REVERSE.
Using minimal accelerator pedal pressure to maintain the rocking motion, without
spinning the wheels, is most effective.
NOTE:
If your vehicle is equipped with Traction Control or Electronic Stability Control (ESC),
turn the system OFF before attempting to “rock” the vehicle.
CAUTION!• Racing the engine or spinning the wheels may lead to transmission overheating
and failure. Allow the engine to idle with the shift lever in NEUTRAL for at least
one minute after every five rocking-motion cycles. This will minimize overheat-
ing and reduce the risk of transmission failure during prolonged efforts to free
a stuck vehicle.
• When “rocking” a stuck vehicle by moving between DRIVE/1st gear and
REVERSE, do not spin the wheels faster than 15 mph (24 km/h), or drivetrain
damage may result.
• Revving the engine or spinning the wheels too fast may lead to transmission
overheating and failure. It can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no transmission shifting occurring).
WARNING!Fast spinning tires can be dangerous. Forces generated by excessive wheel speeds
may cause damage, or even failure, of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle's wheels faster than 30 mph (48 km/h)
or for longer than 30 seconds continuously without stopping when you are stuck
and do not let anyone near a spinning wheel, no matter what the speed.WHAT TO DO IN EMERGENCIES
