300 IN CASE OF EMERGENCY
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 supplement to the
radiator and aids in removing heat from the
engine cooling system.
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. For vehi-
cles with automatic transmission, push and
hold the lock button on the gear selector. Then,
shift back and forth between DRIVE (D) and
REVERSE (R) (with automatic transmission) or
SECOND GEAR (2) and REVERSE (R) (with
manual transmission), while gently pressing the
accelerator. Use the least amount of acceler-
ator pedal pressure that will maintain the
rocking motion, without spinning the wheels or
racing the engine.
NOTE:
For vehicles with automatic transmission:
Shifts between DRIVE (D) and REVERSE (R)
can only be achieved at wheel speeds of
5 mph (8 km/h) or less. Whenever the trans-
mission remains in NEUTRAL (N) for more
than two seconds, you must press the brake
pedal to engage DRIVE (D) or REVERSE (R).
Push the “ESC OFF” switch to place the Elec-
tronic Stability Control (ESC) system in
“Partial Off” mode before rocking the vehicle.
Refer to “Electronic Brake Control System” in
“Safety” for further information. Once the
vehicle has been freed, push the “ESC OFF”
switch again to restore “ESC On” mode.
CAUTION!
Driving with a hot cooling system could
damage your vehicle. If the temperature
gauge reads HOT (H), pull over and stop the
vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops
back into the normal range. If the pointer
remains on HOT (H), and you hear continuous
chimes, turn the engine off immediately and
call for service.
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam coming
from under the hood, do not open the hood
until the radiator has had time to cool. Never
try to open a cooling system pressure cap
when the radiator or coolant bottle is hot.
