178 Driving and Operating
Engine Heater The vehicle may have an engine
heater. The engine heater can help
in cold weather conditions at or
below − 18 °C (0 °F) for easier
starting and better fuel economy
during engine warm-up. Plug in the
heater at least four hours before
starting the vehicle. An internal
thermostat in the plug end of the
cord will prevent engine heater
operation at temperatures above
− 18 °C (0 °F).
To Use The Engine Heater 1. Turn off the engine. 3. Open the hood and unwrap the
electrical cord. The cord is in
the passenger side of the
engine compartment, near the
air filter. It is shipped from the
factory with a tie holding it in
place. Use care in removing
the tie so that the cord is not
damaged.
Check the heater cord for
damage. If it is damaged, do
not use it. See your dealer for
a replacement. Inspect the
cord for damage yearly.
4. Plug it into a normal, grounded
110-volt AC outlet.
{ Warning
Improper use of the heater cord
or an extension cord can damage
the cord and may result in
overheating and fire.
.
Plug the cord into a
three-prong electrical utility
receptacle that is protected
by a ground fault detection
(Continued) Warning (Continued) function. An ungrounded
outlet could cause an
electric shock.
.
Use a weatherproof,
heavy-duty, 15 amp-rated
extension cord if needed.
Failure to use the
recommended extension
cord in good operating
condition, or using a
damaged heater or
extension cord, could make
it overheat and cause a fire,
property damage, electric
shock, and injury.

180 Driving and Operating Warning (Continued)Do not leave the vehicle when the
engine is running. If you have left
the engine running, the vehicle
can move suddenly. You or others
could be injured. To be sure the
vehicle will not move, even when
you are on fairly level ground,
always set the parking brake and
move the shift lever to P (Park).
See Shifting Into Park 0 179 .
If you have to leave the vehicle with
the engine running, the vehicle must
be in P (Park) and the parking brake
set. After shifting into P (Park), try to
move the shift lever without first
pressing the button on the shift
lever. If you can, the shift lever was
not fully locked into P (Park).
Torque Lock
Torque lock is when the weight of
the vehicle puts too much force on
the parking pawl in the
transmission. This happens when
parking on a hill and shifting the transmission into P (Park) is not
done properly and then it is difficult
to shift out of P (Park). To prevent
torque lock, set the parking brake
and then shift into P (Park). To find
out how, see "Shifting Into Park"
listed previously.
If torque lock does occur, the
vehicle may need to be pushed
uphill by another vehicle to relieve
the parking pawl pressure, so you
can shift out of P (Park).
Shifting out of Park To shift out of P (Park):
1. Apply the brake pedal.
2. Turn the ignition on.
3. Press the shift lever button.
4. Move the shift lever.
If you still are unable to shift out of
P (Park):
1. Fully release the shift lever
button.
2. Hold the brake pedal down and
press the shift lever button
again. 3. Move the shift lever.
If you still cannot move the shift
lever from P (Park), see your dealer
for service.
Parking over Things
That Burn
{ WarningThings that can burn could touch
hot exhaust parts under the
vehicle and ignite. Do not park
over papers, leaves, dry grass,
or other things that can burn.
Extended Parking It is best not to park with the vehicle
running. If the vehicle is left running,
be sure it will not move and there is
adequate ventilation.
See Shifting Into Park 0 179 and
Engine Exhaust 0 181 .

Driving and Operating 181If the vehicle is left parked and
running with the RKE transmitter
inside the vehicle, it will continue to
run for up to an hour.
The vehicle could turn off sooner if it
is parked on a hill, due to lack of
available fuel.
The timer will reset if the vehicle is
taken out of P (Park) while it is
running.
Engine Exhaust
{ WarningEngine exhaust contains carbon
monoxide (CO), which cannot be
seen or smelled. Exposure to CO
can cause unconsciousness and
even death.
Exhaust may enter the vehicle if:
.
The vehicle idles in areas
with poor ventilation
(parking garages, tunnels,
deep snow that may block
underbody airflow or tail
pipes).
.
The exhaust smells or
sounds strange or different.
.
The exhaust system leaks
due to corrosion or damage.

Drive Systems All-Wheel Drive Vehicles with this feature transfer
engine power, as required, to all
four wheels. It is fully automatic, and
adjusts itself as needed for road
conditions.
When using a compact spare tire on
an AWD vehicle, the system
automatically detects the compact
spare and reduces AWD
performance to protect the system.
An AWD message may be
displayed. To restore full AWD
operation and prevent excessive
wear on the system, replace the
compact spare with a full-size tire as
soon as possible. See Compact
Spare Tire 0 292 .Brakes Antilock Brake
System (ABS) The Antilock Brake System (ABS)
helps prevent a braking skid and
maintain steering while
braking hard.
ABS performs a system check when
the vehicle is first driven.
A momentary motor or clicking noise
may be heard while this test is going
on, and the brake pedal may move
slightly. This is normal.
If there is a problem with ABS, this
warning light stays on. See Antilock
Brake System (ABS) Warning Light
