Stopping the Engine
Move the shift lever to P (Park) and press the Acc.
button located on the instrument panel. If the shifter is
not in P (Park), the engine shuts off and the vehicle
goes into the Accessory Mode. The DIC displays SHIFT
TO PARK. Once the shifter is moved to P (Park), the
vehicle turns off.
The DIC displays NO FOB, OFF OR RUN?, if the
keyless access transmitter is not detected inside the
vehicle when it is turned off.
SeeDIC Warnings and Messages
on page 4‑76for
more information.
Engine Coolant Heater
The engine coolant heater can provide easier starting
and better fuel economy during engine warm‐up in
cold weather conditions at or below −18°C (0°F).
Vehicles with an engine coolant heater should be
plugged in at least four hours before starting. Some
models have an internal thermostat in the cord which
will prevent engine coolant heater operation at
temperatures above −18°C (0°F).
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is located in the front of the engine
compartment, on the passenger side of the vehicle.
3. You must remove the plastic cap to access the plug.
4. Plug it into a normal, grounded 110-volt AC outlet.
{WARNING:
Plugging the cord into an ungrounded outlet could
cause an electrical shock. Also, the wrong kind of
extension cord could overheat and cause a fire.
You could be seriously injured. Plug the cord into
a properly grounded three-prong 110-volt AC
outlet. If the cord will not reach, use a heavy-duty
three-prong extension cord rated for at least
15 amps.
5. 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.

Engine Coolant Temperature
Warning Light
The engine coolant
temperature warning light
comes on when the
engine is very hot.
This light also comes on briefly when the vehicle is
started.
If the light does not go out or comes on and stays on
while driving, there may be a problem with the cooling
system. Driving with engine coolant temperature light on
could cause the vehicle to overheat, see Overheated
Engine Protection Operating Mode
on page 6‑32. See
Engine Overheatingon page 6‑30and DIC Warnings
and Messageson page 4‑76for more information.
Engine Coolant Temperature Gauge
This gauge shows
the engine coolant
temperature.
It can be used to see when the engine has warmed
up and to make sure the cooling system is operating
properly. If the gauge pointer moves into the shaded
area, the engine coolant is too hot and the engine
coolant temperature warning light comes on. See
Engine Overheating
on page 6‑30for more
information.

ENGINE COOLANT HOT IDLE ENGINE
Notice:If you drive your vehicle while the engine is
overheating, severe engine damage may occur. If an
overheat warning appears on the instrument panel
cluster and/or DIC, stop the vehicle as soon as
possible. Do not increase the engine speed above
normal idling speed. See Engine Overheating
on
page 6‑30for more information.
This symbol appears
with this message.
This message displays when the engine coolant
temperature is too hot. Stop and allow the vehicle to
idle until it cools down. See Engine Coolant
Temperature Warning Light on page 4‑61.
See Overheated Engine Protection Operating Mode
on
page 6‑32for information on driving to a safe place in
an emergency.
ENGINE HOT –AC
(Air Conditioning) OFF
This message displays when the engine coolant
becomes hotter than the normal operating temperature.
See Engine Coolant Temperature Gauge
on
page 4‑61. To avoid added strain on a hot engine, the
air conditioning compressor is automatically turned off.
When the coolant temperature returns to normal, the air
conditioning compressor turns back on. You can
continue to drive your vehicle.
If this message continues to appear, have the system
repaired by your dealer as soon as possible to avoid
damage to the engine.
ENGINE POWER REDUCED
This message displays when the engine power is
being reduced to protect the engine from damage.
There could be several malfunctions that might cause
this message. Reduced engine power can affect the
vehicle's ability to accelerate. If this message is on, but
there is no reduction in performance, proceed to your
destination. The performance may be reduced the
next time the vehicle is driven. The vehicle may be
driven at a reduced speed while this message is on, but
acceleration and speed may be reduced. Anytime this
message stays on, take the vehicle to your dealer for
service as soon as possible.

Driving On Grades
Reduce speed and shift to a lower gearbeforestarting
down a long or steep downgrade. If the transmission is
not shifted down, the brakes might have to be used so
much that they would get hot and no longer work well.
On a long uphill grade, shift down and reduce the
vehicle's speed to around 45 mph (70 km/h) to reduce
the possibility of the engine and the transmission
overheating.
Vehicles can tow in D (Drive). Shift the transmission to
a lower gear if the transmission shifts too often under
heavy loads and/or hilly conditions.
When towing at high altitude on steep uphill grades,
consider the following: Engine coolant will boil at a
lower temperature than at normal altitudes. If the engine
is turned off immediately after towing at high altitude on
steep uphill grades, the vehicle may show signs similar
to engine overheating. To avoid this, let the engine run
while parked, preferably on level ground, with the
automatic transmission in P (Park) for a few minutes
before turning the engine off. If the overheat warning
comes on, see Engine Overheating on page 6‑30.
Parking on Hills
{WARNING:
Parking the vehicle on a hill with the trailer
attached can be dangerous. If something goes
wrong, the rig could start to move. People can be
injured, and both the vehicle and the trailer can be
damaged. When possible, always park the rig on
a flat surface.
If parking the rig on a hill: 1. Press the brake pedal, but do not shift into P (Park) yet. Turn the wheels into the curb if facing downhill
or into traffic if facing uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until the chocks absorb the load.
4. Reapply the brake pedal. Then apply the parking brake and shift into P (Park).
5. Release the brake pedal.
