hours before starting your vehicle. An
internal thermostat in the plug-end of
the cord may exist which will prevent
engine heater operation at
temperatures above−18 °C (0 °F).
The engine heater cord requires the
front license plate mounting bracket
to be installed. See your dealer for
more information.
To Use the Engine Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The cord is clipped
to the diagonal brace on the
passenger side of the engine
compartment.
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.
3. 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 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.
.Do not operate the vehicle with
the heater cord permanently
attached to the vehicle. Possible
heater cord and thermostat
damage could occur.
(Continued)
Warning (Continued)
.While in use, do not let the
heater cord touch vehicle parts
or sharp edges. Never close the
hood on the heater cord.
.Before starting the vehicle,
unplug the cord, reattach the
cover to the plug, and securely
fasten the cord. Keep the cord
away from any moving parts.
4. Before starting the engine, be sure to unplug and store the cord as it
was before to keep it away from
moving engine parts. If you do not,
it could be damaged.
Contact your dealer for information
on how long to use the heater in your
particular area.

Shifting Into Park
(Mechanical Shifter)
1. Hold the brake pedal down and setthe parking brake. See Electric
Parking Brake 0254.
2. Move the shift lever into P (Park) by holding in the button on the
shift lever and pushing the shift
lever all the way toward the front
of the vehicle.
3. Turn the ignition off.
Leaving the Vehicle with the
Engine Running
{Warning
It can be dangerous to leave the
vehicle with the engine running.
It could overheat and catch fire.
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
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 (Mechanical Shifter) 0238
or
Shifting Into Park (Electronic Shifter)
0 239. If you are towing a trailer,
see Driving Characteristics and
Towing Tips 0315. If you have to leave the vehicle with
the engine running, be sure the
vehicle is in P (Park) and the parking
brake is set before you leave it. After
you have moved the shift lever into
P (Park), hold the regular brake pedal
down. Then, see if you can move the
shift lever away from P (Park) without
first pressing the button.
If you can, it means that the shift
lever was not fully locked in 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, your vehicle
may need to be pushed uphill by
another vehicle to relieve the parking
pawl pressure, so you can shift out of
P (Park).
