HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located on the
switch bank just above the climate controls.
Push the switch to turn on the Hazard Warning
flasher. When the switch is activated, all direc-
tional turn signals will flash on and off to warn oncoming
traffic of an emergency. Push the switch a second time to
turn off the Hazard Warning flashers.
This is an emergency warning system and it should not
be used when the vehicle is in motion. Use it when your
vehicle is disabled and it is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning flashers will continue to operate even
though the ignition is placed in the OFF position.
NOTE:With extended use, the Hazard Warning flashers
may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
•On the highways — slow down.
•In city traffic — while stopped, place the transmission
in NEUTRAL, but do not increase the engine idle
speed while maintaining the motion of the vehicle
with the brakes.
NOTE:There are steps that you can take to slow down
an impending overheat condition:
•If your air conditioner (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
•You can also turn the temperature control to maximum
heat, the mode control to floor and the blower control
to high. This allows the heater core to act as a

CAUTION!(Continued)
the vehicle’s battery will discharge sufficiently to
degrade battery life and/or prevent the engine from
starting.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it
can often be moved using a rocking motion. Turn the
steering wheel right and left to clear the area around the
front wheels. Push and hold the lock button on the shift
lever. Then shift back and forth between DRIVE and
REVERSE while gently pressing the accelerator.
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 push 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 theESC Offswitch (if necessary), to place
the Electronic Stability Control (ESC) system inPartial
Offmode, before rocking the vehicle. Refer to “Elec-
tronic Brake Control” in “Starting And Operating” for
further information. Once the vehicle has been freed,
push theESC Offswitch again to restoreESC On
mode.
CAUTION!
Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine to idle with the transmission in NEUTRAL for at
least one minute after every five rocking-motion
cycles. This will minimize overheating and reduce

normal. Any belt with cracks running along a rib must be
replaced. Also have the belt replaced if it has excessive
wear, frayed cords or severe glazing.
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-
