3. Snap the front and back together tightly so
moisture will not get inside the transmitter.
4. Test the operation of the transmitter with the
vehicle.
Remote Vehicle Start
Your vehicle may have a remote start feature.
This feature allows you to start the engine
from outside the vehicle. It may also start the
vehicle’s heating or air conditioning systems.
When you start your vehicle using the remote start
feature, the climate control system will come on
and adjust the interior to the temperature settings
that you left it set to when you turned the
vehicle off.
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.The remote start feature provides two separate
starts per ignition cycle, each with 10 minutes
of engine running time.
After your vehicle’s engine has been started
two times using the remote vehicle start button,
the vehicle’s ignition switch must be turned to RUN
and then back to LOCK using the key before
the remote start procedure can be used again.
SeeIgnition Positions on page 112for information
regarding the ignition positions on your vehicle.
You can start your vehicle’s engine from about
197 feet (60 m) away. However, the range may be
less while the vehicle is running, and as a result
you may need to be closer to your vehicle to turn it
off than you were to turn it on.
There are other conditions which can affect the
performance of the transmitter, seeRemote
Keyless Entry (RKE) System on page 91for
additional information.
/(Remote Start):If your vehicle has the remote
start feature, the RKE transmitter will have a
button with this symbol on it.

Your vehicle may have an ashtray and cigarette
lighter. To use the lighter, located on the
instrument panel below the climate controls,
push it in all the way and let go. When it is ready,
it will pop back out by itself.
Notice:Holding a cigarette lighter in while it
is heating will not allow the lighter to back
away from the heating element when it is hot.
Damage from overheating may occur to the
lighter or heating element, or a fuse could
be blown. Do not hold a cigarette lighter
in while it is heating. Do not use equipment
exceeding maximum amperage rating of
15 amperes.
To clean the center console ashtray, remove the
entire ashtray and empty it.

cooling, and ventilation for the vehicle.
Operation
To change the current mode, select one of the
following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs about half of
the air to the instrument panel outlets, and
then directs the remaining air to the oor outlets.
Cooler air is directed to the upper outlets and
warmer air to the oor outlets.
6(Floor):This mode directs most of the air to
the oor outlets with some air directed to the
windshield and side windows.
The left knob can also be used to select defog or

Engine Coolant Temperature
Warning Light
The engine coolant
temperature warning
light will come on
when the engine
has overheated.
If this happens you should pull over and turn off
the engine as soon as possible. SeeEngine
Overheating on page 309for more information.
Notice:Driving with the engine coolant
temperature warning light on could cause your
vehicle to overheat. SeeEngine Overheating
on page 309. Your vehicle could be damaged,
and it might not be covered by your warranty.
Never drive with the engine coolant
temperature warning light on.
This light will also come on briey when starting
your vehicle. If it does not, have your vehicle
serviced.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle has a
computer which
monitors operation
of the fuel, ignition,
and emission control
systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment. The check engine light comes on
to indicate that there is a problem and service is
required. Malfunctions often will be indicated by
the system before any problem is apparent. This
may prevent more serious damage to your vehicle.
This system is also designed to assist your service
technician in correctly diagnosing any malfunction.

Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal asher and/or extra wiring.
Check with your dealer. The arrows on your
instrument panel will ash whenever you signal a
turn or lane change. Properly hooked up, the
trailer lamps will also ash, telling other drivers
you are about to turn, change lanes or stop.
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 is 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 gearbefore
you start down a long or steep downgrade. If you
do not shift down, you might have to use your
brakes so much that they would get hot and
no longer work well.
Pay attention to the engine coolant gage. If the
indicator is in the red area, turn off the air
conditioning to reduce engine load. SeeEngine
Overheating on page 309.
When towing under severe conditions such as hot
ambient temperatures or steep grades, your
vehicle may experience more transaxle shifting.
A COOLING MODE ON message may also appear
in the DIC. This alerts the driver that the shifting
mode is in progress and is aiding engine cooling.
SeeDIC Warnings and Messages on page 184
for more information.

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.
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 are pulling a trailer. SeeScheduled
Maintenance on page 396for more on this.
Things that are especially important in trailer
operation are transaxle uid (do not overll),
engine oil, 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
are trailering, it is 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 309.
