Remote Vehicle Start
Your vehicle may have a remote starting feature.
This feature allows you to start the engine
from outside of the vehicle. It may also start up
the vehicle’s heating or air conditioning systems
and rear window defogger. Normal operation of the
system will return after the key is turned to the
RUN position.
If your vehicle has an automatic climate control
system, during remote start, the climate control
system will default to a heating mode during colder
outside temperatures and a cooling mode during
warmer outside temperatures. If your vehicle
does not have an automatic climate control
system, during remote start the climate control
system will turn on at the setting the vehicle was
set to when the vehicle was last turned off.Laws in some communities may restrict the use of
remote starters. For example, some laws may
require a person using the 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 RKE transmitter with the remote start button,
provides an increased range of operation.
However, the range may be less while the vehicle
is running. 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 System on page 114for additional
information.

When the PASS-Key®III+ system senses that
someone is using the wrong key, it prevents the
vehicle from starting. Anyone using a trial-and-error
method to start the vehicle will be discouraged
because of the high number of electrical key codes.
If the engine does not start and the security light
on the instrument panel comes on when trying
to start the vehicle, the key may have a damaged
transponder. Turn the ignition off and try again.
If the engine still does not start, and the key
appears to be undamaged, try another ignition key.
At this time, you may also want to check the fuse,
seeFuses and Circuit Breakers on page 507.Ifthe
engine still does not start with the other key, your
vehicle needs service. If your vehicle does start, the
rst key may be faulty. See your dealer who can
service the PASS-Key
®III+ to have a new key
made. In an emergency, contact Roadside
Assistance.It is possible for the PASS-Key
®III+ decoder to
“learn” the transponder value of a new or
replacement key. Up to nine additional keys may
be programmed for the vehicle. The following
procedure is for programming additional keys only.
If all the currently programmed keys are lost or
do not operate, you must see your dealer or
a locksmith who can service PASS-Key
®III+ to
have keys made and programmed to the system.
See your dealer or a locksmith who can service
PASS-Key
®III+ to get a new key blank that is cut
exactly as the ignition key that operates the
system.
To program the new additional key do the
following:
1. Verify that the new key has a
1stamped on it.
2. Insert the original, already programmed, key
in the ignition and start the engine. If the
engine will not start, see your dealer
for service.

2. If the engine does not start within 10 seconds,
push the accelerator pedal all the way to the
oor, while you hold the ignition key in
START. When the engine starts, let go of the
key and let up on the accelerator pedal.
Wait about 15 seconds between each try.
When starting your engine in very cold weather
(below 0°F or−18°C), do this:
1. With your foot off the accelerator pedal, turn
the ignition key to START and hold it there up
to 15 seconds. When the engine starts, let
go of the key.
2. If your engine still will not start, or starts but
then stops, it could be ooded with too much
gasoline. Try pushing your accelerator
pedal all the way to the oor and holding it
there as you hold the key in START for about
three seconds. When the engine starts, let
go of the key and accelerator. If the vehicle
starts briey but then stops again, do the
same thing, but this time keep the pedal down
for ve or six seconds. This clears the extra
gasoline from the engine.Notice:Your engine is designed to work with
the electronics in your vehicle. If you add
electrical parts or accessories, you could
change the way the engine operates. Before
adding electrical equipment, check with
your dealer. If you do not, your engine might
not perform properly. Any resulting damage
would not be covered by your vehicle’s
warranty.
Adjustable Throttle and Brake Pedal
If your vehicle has this feature, you can change
the position of the throttle and brake pedals.
This feature is designed for shorter drivers, since
the pedals can not move farther away from
the standard position, but can move toward the
driver for better pedal reach.
The feature will not operate when the vehicle is in
REVERSE (R) or while using the cruise control.
142

The recirculation mode cannot be selected while in
the defrost mode. The air conditioning compressor
will run automatically in this setting, unless the
outside temperature is close to freezing. Do not
drive the vehicle until all the windows are clear.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(Rear Window Defogger):The rear window
defogger will turn off automatically after it has
been activated. The defogger can also be turned
off by pressing the button again or by turning
off the engine. Do not drive the vehicle until all the
windows are clear.
If your vehicle has heated outside rearview
mirrors, the mirrors will heat to help clear fog or
frost from the surface of the mirror when the
rear window defog button is pressed.
Notice:Do not use a razor blade or sharp
object to clear the inside rear window. Do not
adhere anything to the defogger grid lines
in the rear glass. These actions may damage
the rear defogger. Repairs would not be
covered by your warranty.
Outlet Adjustment
Use the air outlets located in the center and on
the side of your instrument panel to direct
the airow.
Operation Tips

Keep the hood and front air inlets free of ice,
snow, or any other obstruction (such as
leaves). The heater and defroster will work far
better, reducing the chance of fogging the
inside of your windows.
When you enter a vehicle in cold weather,
press the fan up button to the maximum
fan level before driving. This helps clear the
intake ducts of snow and moisture, and
reduces the chance of fogging the inside of
your window.
Keep the air path under the front seats
clear of objects. This helps air to circulate
throughout your vehicle.
Adding outside equipment to the front of your
vehicle, such as hood-air deectors, may
affect the performance of the heating and air
conditioning system. Check with your dealer
before adding equipment to the outside of your
vehicle.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages
on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that
something is wrong before it becomes serious
enough to cause an expensive repair or
replacement. Paying attention to your warning
lights and gages could also save you or others
from injury.
Warning lights come on when there may be or
is a problem with one of your vehicle’s functions.
As you will see in the details on the next few
pages, some warning lights come on briey when
you start the engine just to let you know they’re
working. If you are familiar with this section,
you should not be alarmed when this happens.Gages can indicate when there may be or is a
problem with one of your vehicle’s functions.
Often gages and warning lights work together to
let you know when there’s a problem with
your vehicle.
When one of the warning lights comes on and
stays on when you are driving, or when one of
the gages shows there may be a problem, check
the section that tells you what to do about it.
Please follow this manual’s advice. Waiting to do
repairs can be costly – and even dangerous.
So please get to know your warning lights and
gages. They’re a big help.
Your vehicle also has a Driver Information Center
(DIC) that works along with the warning lights
and gages. SeeDriver Information Center (DIC)
on page 245.
228

Speedometer and Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers
per hour (km/h).
Your vehicle’s odometer works together with the
driver information center. You can set a Trip
odometer. See “Trip Odometer” underDIC
Operation and Displays on page 245for more
information.
The odometer mileage can be checked without the
vehicle running. Simply press the trip stem on
the instrument panel cluster.
If your vehicle ever needs a new odometer
installed, the new one will be set to the correct
mileage total of the old odometer.
Trip Odometer
The trip odometer can tell you how far your
vehicle has been driven since you last set the trip
odometer to zero.
For more information see “Trip Odometer” under
DIC Operation and Displays on page 245.
Tachometer
Your tachometer displays the engine speed in
revolutions per minute (rpm).
230

Charging System Light
The charging system
light will come on briey
when you turn on the
ignition, but the
engine is not running,
as a check to show you
it is working.
It should go out once the engine is running. If it
stays on, or comes on while you are driving,
you may have a problem with the charging system.
It could indicate that you have problems with the
generator, the generator drive belt, or another
electrical problem. Have it checked right away.
Driving while this light is on could drain your
battery.
When this light comes on, the DIC will also display
the SERVICE BATTERY NOT CHARGING
SYSTEM message. SeeDIC Warnings and
Messages on page 250for more information.If you must drive a short distance with the light on,
be certain to turn off all your accessories, such
as the radio and air conditioner, to reduce
the drain on your battery.
Brake System Warning Light
With the ignition on, the brake system warning
light will come on when you set the parking brake.
If you try to drive with the parking brake engaged,
a chime will sound when the vehicle speed is
greater than 3 mph (5 km/h).
Your vehicle’s hydraulic brake system is divided
into two parts. If one part is not working, the
other part can still work and stop you. For good
braking, though, you need both parts working well.
235

If the StabiliTrak®system warning light comes
on and stays on for an extended period of
time when the system is turned on, your vehicle
needs service. SeeStabiliTrak
®System on
page 330for more information.
Engine Coolant Temperature Gage
This gage shows the
engine coolant
temperature.
If the gage pointer moves towards the shaded in
thermostat, 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 422.
Tire Pressure Light
This light will come on
briey when you turn
the ignition to RUN.
This light will also come on when one or more of
your tires are signicantly underinated.
If equipped, a CHECK TIRE PRESSURE DIC
message will accompany the light.
Stop and check your tires as soon as it is safe to do
so. If underinated, inate to the proper pressure.
SeeTires on page 454for more information.
This light will ash for 60 seconds and then turn
on solid if a problem is detected with the Tire
Pressure Monitor system.
SeeTire Pressure Monitor System on page 462
for more information.
238

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.Notice:If you keep driving your vehicle with
this light on, after awhile, your emission
controls may not work as well, your fuel
economy may not be as good, and your engine
may not run as smoothly. This could lead to
costly repairs that may not be covered by your
warranty.
Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system
of your vehicle or the replacement of the
original tires with other than those of the same
Tire Performance Criteria (TPC) can affect
your vehicle’s emission controls and may
cause this light to come on. Modications to
these systems could lead to costly repairs not
covered by your warranty. This may also
result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 396.
239

This light should come on, as a check to show
you it is working, when the ignition is on and the
engine is not running. If the light does not
come on, have it repaired. This light will also
come on during a malfunction in one of two ways:
Light Flashing— A misre condition has
been detected. A misre increases vehicle
emissions and may damage the emission
control system on your vehicle. Diagnosis and
service may be required.
Light On Steady— An emission control
system malfunction has been detected on your
vehicle. Diagnosis and service may be
required.
If the Light is Flashing
The following may prevent more serious damage
to your vehicle:
Reducing vehicle speed
Avoiding hard accelerations
Avoiding steep uphill grades
If you are towing a trailer, reduce the amount
of cargo being hauled as soon as it is
possibleIf the light stops ashing and remains on steady,
see “If the Light Is On Steady” following.
If the light continues to ash, when it is safe to do
so, stop the vehicle. Find a safe place to park
your vehicle. Turn the key off, wait at least
10 seconds and restart the engine. If the light
remains on steady, see “If the Light Is On Steady”
following. If the light is still ashing, follow the
previous steps, and see your dealer for service as
soon as possible.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully
install the cap. SeeFilling the Tank on page 401.
The diagnostic system can determine if the fuel cap
has been left off or improperly installed. A loose or
missing fuel cap will allow fuel to evaporate into the
atmosphere. A few driving trips with the cap
properly installed should turn the light off.
