Dodge 2009 Ram 1500 - Manual (Page 438)

CAUTION!
It is very important that the starting unit operating
voltage does not exceed 12-Volts DC or damage to the
battery, starter motor, alternator or electrical system
may occur.
FREEING A STUCK VEHICLE
If the vehicle becomes stuck in snow, sand or mud, it can
often be moved by a rocking motion. Move the shift lever
rhythmically between DRIVE and REVERSE while ap-
plying slight pressure to the accelerator.
CAUTION!
Revving the engine and shifting aggressively be-
tween forward and reverse may damage the vehicle
and lead to extensive repair.
In general, the least amount of accelerator pedal pressure
to maintain the rocking motion without spinning the
wheels or racing the engine is most effective.
CAUTION!
Racing the engine or spinning the wheels due to the
frustration of not freeing the vehicle may lead to
transmission overheating and failure.
Allow the engine to idle with the transmission shift lever
in NEUTRAL for at least one minute after every five
rocking-motion cycles. This will minimize overheating
and reduce the risk of transmission failure during pro-
longed efforts to free a stuck vehicle.
