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. See
Climate Control System on page 170for
additional information.
Laws in some local 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.
/(Remote Vehicle Start):If your vehicle has
the remote vehicle start feature, the remote
keyless entry transmitter will have a button with
this symbol on it.
An increased range of operation is provided with
the remote keyless entry transmitter that has
the remote vehicle start button. The vehicle can
be started from approximately 197 feet (60 m)
away. However, the operating range may be less
while the engine is running and you will need
to be closer to your vehicle to turn it off than you
were to turn it on.Do not use the remote start feature if your vehicle
is low on fuel. Your vehicle may run out of fuel.
To start the engine using the remote start feature,
do the following:
1. Aim the remote keyless entry transmitter at
the vehicle.
2. Press and release the transmitter’s lock button,
then immediately press and hold the remote
vehicle start button for four seconds or until the
vehicle’s turn signal lamps ash. The vehicle’s
doors will be locked.
3. When the vehicle’s engine starts, the parking
lamps will turn on and remain on while the
engine is running.
After a remote start, the engine will automatically
shut off after 10 minutes unless a time extension
has been done or the vehicle’s key is inserted into
the ignition switch and turned to RUN.
The maximum number of remote starts between
ignition cycles with the key is two.
If the remote start procedure is used again before
the rst 10 minute time frame has ended, the
rst 10 minutes will immediately expire and
the second 10 minute time frame will start.

{CAUTION:
It can be dangerous to drive with the
liftgate 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 liftgate open or if
electrical wiring or other cable
connections must pass through the seal
between the body and the liftgate:
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 System on page 170.
If you have air outlets on or under the
instrument panel, open them all the
way. SeeEngine Exhaust on page 132.
Manual Liftgate Release
If the liftgate cannot be opened by pressing the
switch on the outside handle, the battery may
be run down. SeeJump Starting on page 320.
To manually open the liftgate, do the following:
1. Remove the trim plug, located on the inside of
the liftgate near the center.
107

Ashtray(s) and Cigarette Lighter
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.
Notice:If you put papers, pins, or other
ammable items in the ashtray, hot cigarettes
or other smoking materials could ignite
them and possibly damage your vehicle. Never
put ammable items in the ashtray.
Climate Controls
Climate Control System
With this system you can control the heating,
cooling, and ventilation for your vehicle.
If your vehicle has remote start and you want to
warm up or cool down the interior before you
get in, leave your climate control system on with
the settings adjusted where you want them.
The next time the vehicle is started with remote
start, the climate control system will come on and
adjust the interior to the temperature settings.

Enhanced Traction System
Warning Light
If your vehicle is
equipped with the
Enhanced Traction
System (ETS),
this warning light should
come on briey as
you start the engine.
If the warning light does not come on, then have it
xed so it will be ready to warn you if there is a
problem.
If the warning light stays on, or comes on when
you are driving, there may be a problem with your
Enhanced Traction System and your vehicle
may need service. When this warning light is on,
the system will not limit wheel spin. Adjust
your driving accordingly.
SeeEnhanced Traction System (ETS) on
page 246for more information.
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.
187

Engine Coolant Temperature Gage
Your vehicle has an
engine coolant
temperature gage. With
the ignition turned to
RUN, this gage shows
the engine coolant
temperature.
If the gage pointer moves into the red area, your
engine is too hot. It means that your engine
coolant has overheated.
If you have been operating your vehicle under
normal driving conditions, you should pull off the
road, stop your vehicle and turn off the engine
as soon as possible.
SeeEngine Overheating on page 309.
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.
188

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.
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
is how to do it:
1. Apply your regular brakes, but do not shift into
PARK (P) for an automatic transaxle, or into
gear for a manual transaxle. When parking
uphill, turn your wheels away from the
curb. When parking downhill, turn your wheels
into the curb.
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 regular brakes. Then apply your
parking brake, and then shift into PARK (P) for
an automatic transaxle or REVERSE (R) for a
manual transaxle.
5. Release the regular brakes.
285

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 393for more on this.
Things that are especially important in trailer
operation are automatic 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.

Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. This system does not have its own
reservoir. It receives uid from the brake master
cylinder reservoir.
SeeBrakes on page 317for more information.
Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is
designed to remain in your vehicle for ve years or
150,000 miles (240 000 km), whichever occurs
rst, if you add only DEX-COOL
®extended
life coolant.
The following explains your cooling system and
how to add coolant when it is low. If you have
a problem with engine overheating, seeEngine
Overheating on page 309.A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
Give freezing protection down
to−34°F (−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.
Notice:Using coolant other than DEX-COOL
®
may cause premature engine, heater core,
or radiator corrosion. In addition, the engine
coolant may require changing sooner, at
the rst maintenance service after each
30,000 miles (50 000 km) or 24 months,
whichever occurs rst. Any repairs would not
be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your
vehicle.
306

{CAUTION:
You can be burned if you spill coolant on
hot engine parts. Coolant contains
ethylene glycol, and it will burn if the
engine parts are hot enough. Do not spill
coolant on a hot engine.
Pressure Cap
Notice:If the pressure cap is not tightly
installed, coolant loss and possible engine
damage may occur. Be sure the cap is properly
and tightly secured.
SeeEngine Compartment Overview on page 298
for more information on location.
Engine Overheating
You will nd a coolant temperature warning light
and a coolant temperature gage on your vehicle’s
instrument panel. SeeEngine Coolant
Temperature Warning Light on page 187and
Engine Coolant Temperature Gage on page 188
for more information.
