Remote Vehicle Start
Your vehicle may have a remote starting feature that
allows you to start the engine from outside the vehicle.
It may also start the vehicle’s heating or air conditioning
systems and rear window defogger. When the remote
start system is active and the vehicle has an automatic
climate control system, it will automatically regulate
the inside temperature. Normal operation of these
systems will return after the ignition key is turned to
ON/RUN.
Laws in some communities may restrict the use of
remote starters. For example, some laws may require a
person using remote start to have the vehicle in view
when doing so. Check local regulations for any
requirements on remote starting of vehicles.
Do not use the remote start feature if your vehicle is low
on fuel. Your vehicle may run out of fuel.
If your vehicle has the remote start feature, the RKE
transmitter functions will have an increased range
of operation. However, the range may be less while the
vehicle is running.
There are other conditions which can affect the
performance of the transmitter, seeRemote Keyless
Entry (RKE) System on page 2-4for additional
information.

{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the trunk lid
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See Climate Control

(80 km/h), the rear window defogger remains on once
the button is pressed.
If your vehicle has heated outside mirrors, the surface
of the outside mirrors heat when the rear window
defogger is activated. SeeOutside Power Mirrors on
page 2-41.
Notice:Do not use anything sharp on the inside of
the rear window. If you do, you could cut or
damage the warming grid, and the repairs would not
be covered by the vehicle warranty. Do not attach
a temporary vehicle license, tape, a decal or
anything similar to the defogger grid.
Remote Start Climate Control Operation
If your vehicle has the remote start feature and it
is activated, the climate control system heats or cools
the inside of the vehicle using the modes that were
set before the vehicle was turned off. The climate control
knobs will remain active during a remote start.
However, the climate control buttons will be inactive
until the ignition is turned on by the key. If the fan is off,
the climate control system will not operate during
remote start. SeeRemote Keyless Entry (RKE) System

When the weather is cool or damp, operating the
system in recirculation for extended periods of time can
cause fogging of the vehicle’s windows. To clear the
fog, select either defog or defrost. Make sure the
air conditioning is on. Allow the air conditioning to run
automatically to help dehumidify the air.
Temperature Control:Press the up and down arrows
to increase or decrease the temperature inside the
vehicle.
#(Air Conditioning):Press this button to turn the air
conditioning compressor on and off. A light above
the button comes on while the air conditioning is on.
When air conditioning is selected or is in AUTO mode,
the system runs the air conditioning automatically to
cool and dehumidify the air entering the vehicle.
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for
the vehicle to cool down. Then keep the windows closed
for the air conditioner to work its best.On cool, but sunny days while using manual operation
of the automatic system, use bi-level to deliver warm
air to the oor and cooler air to the instrument
panel outlets. To warm or cool the air delivered, press
the temperature buttons to the desired setting.
In AUTO mode the system cools and dehumidies the
air inside the vehicle. Also while in AUTO mode,
the system maximizes its performance by using
recirculation as necessary.
Heating:On cold days when using manual operation of
the automatic system, use oor mode to deliver air to
the oor outlets. To warm or cool the air delivered, push
the temperature buttons to the desired setting.
To use the automatic mode, turn the knob to AUTO and

When towing a trailer, the arrows on your instrument
panel will ash for turns even if the bulbs on the trailer
are burned out. Thus, you may think drivers behind
you are seeing your signal when they are not. It’s
important to check occasionally to be sure the trailer
bulbs are still working.
Driving on Grades
Notice:Do not tow on steep continuous grades
exceeding 6 miles (9.6 km). Extended, higher
than normal engine and transmission temperatures
may result and damage your vehicle. Frequent
stops are very important to allow the engine and
transmission to cool.
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don’t shift
down, you might have to use your brakes so much
that they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your
speed to around 45 mph (70 km/h) to reduce the
possibility of the engine and the transmission
overheating. If your engine does overheat, see
Engine Overheating on page 5-29.
Parking on Hills
{CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People
can be injured, and both your vehicle and the
trailer can be damaged.
But if you ever have to park your rig on a hill, here’s
how to do it:
1. Apply your regular brakes, but don’t shift into
PARK (P).
When parking uphill, turn your wheels away from
the curb. When parking downhill, turn your wheels
into the curb.
2. Have someone place chocks behind the trailer
wheels.
3. When the chocks are in place, release the regular
brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your
parking brake and shift into PARK (P).
5. Release the regular brakes.
4-35

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
start your engine
shift into a gear, and
release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. SeeScheduled Maintenance on
page 6-4for more information. Things that are especiallyimportant in trailer operation are automatic transmission
uid (don’t overll), engine oil, axle lubricant, drive
belt, cooling system and brake system. Each of these is
covered in this manual, and the Index will help you
nd them quickly. If you’re trailering, it’s a good idea to
review this information before you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. SeeEngine Overheating on
page 5-29.
Changing a Tire When Trailer Towing
If you get a at tire while towing a trailer, be sure
to secure the trailer and disconnect it from the vehicle
before changing the tire.
