2016 JEEP GRAND CHEROKEE ECO mode

NOTE:Shifts between DRIVE and REVERSE can only be
achieved at wheel speeds of 5 mph (8 km/h) or less.
Whenever the transmission remains in NEUTRAL for
more than two seconds, you must press the brake pedal
to engage DRIVE or REVERSE.
Use the least amount of accelerator pedal pressure that
will maintain the rocking motion without spinning the
wheels or racing the engine.
NOTE: Push the ESC Off switch (if necessary), to place
the Electronic Stability Control (ESC) system in Partial
Off mode, before rocking the vehicle. Refer to “Elec-
tronic Brake Control” in “Starting And Operating” for
further information. Once the vehicle has been freed,
push the ESC Off switch again to restore ESC On
mode.CAUTION!
• Racing the engine or spinning the wheels may lead
to transmission overheating and failure. Allow the
engine to idle with the transmission 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.
• When “rocking” a stuck vehicle by shifting be-
tween DRIVE 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 trans-
mission shifting occurring).

WHAT TO DO IN EMERGENCIES 601

Conditions that would require replacement:
•Rib chunking (one or more ribs has separated from belt
body)
• Rib or belt wear
• Longitudinal belt cracking (cracks between two ribs) •
Belt slips
• “Groove jumping (belt does not maintain correct
position on pulley)
• Belt broken (note: identify and correct problem before
new belt is installed)
• Noise (objectionable squeal, squeak, or rumble is
heard or felt while drive belt is in operation)
Some conditions can be caused by a faulty component
such as a belt pulley. Belt pulleys should be carefully
inspected for damage and proper alignment.
Belt replacement on some models requires the use of
special tools, we recommend having your vehicle ser-
viced at an authorized dealer.
