3. Put the two halves back together. Make sure
the cover is on tight so water 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 and
rear window defogger. When the remote start
system is active, the climate control system will
heat or cool the inside of the vehicle based on the
outside temperature. The rear window defogger
will be turned on by the climate control system
when it is heating the inside of the vehicle. Normal
operation of the system will return after the key
is turned to 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.
The remote start feature provides two separate
starts per ignition cycle, each with 10 minutes of
engine running time.
The remote start system needs to be reset after
your vehicle’s engine is started two times using the
transmitter’s remote start button. The remote
start system is reset by inserting the vehicle’s key
into the ignition switch and turning to RUN.
SeeIgnition Positions on page 105for information
regarding the ignition positions on your vehicle.
Your remote keyless entry transmitter with
the remote start button provides an increased
range of operation. You can start your vehicle from
about 492 feet (150 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 86for
additional information.

PASS-Key®III Operation
The vehicle is
equipped with
PASS-Key
®III
(Personalized
Automotive Security
System) theft-deterrent
system. PASS-Key
®III
is a passive
theft-deterrent
system.
This means nothing special needs to be done to
arm or disarm the system. It works when the key is
inserted or removed from the ignition.
PASS-Key
®III uses a transponder in the ignition
key that matches a decoder in the vehicle.
When the PASS-Key
®III system senses that the
wrong key has been inserted into the ignition, it
shuts down the vehicle’s starter and fuel systems.The starter will not work and fuel will stop owing to
the engine. If someone tries to start the vehicle
again with the wrong key, the vehicle will not start.
Anyone using a trial-and-error method to start the
vehicle will be discouraged to do so because of the
high number of electrical key codes.
When trying to start the vehicle, if the engine does
not start and the STARTING DISABLED DUE TO
THEFT SYSTEM warning message on the Driver
Information Center (DIC) comes on, 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 460.Ifthe
engine still does not start with the other key, the
vehicle needs service. If the 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.
SeeRoadside Assistance Program on page 498for
more information.

2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F
or−18°C), it could be ooded with too much
gasoline. Try pushing the accelerator
pedal all the way to the oor and holding it
there as you hold the key in START for up to
a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the
cranking motor to cool down. When the engine
starts, let go of the key and accelerator. If
the vehicle starts briey but then stops again,
do the same thing. This clears the extra
gasoline from the engine. Do not race the
engine immediately after starting it. Operate
the engine and transaxle gently until the
oil warms up and lubricates all moving parts.
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.Engine Coolant Heater
The vehicle may be equipped with an engine
coolant heater. In very cold weather, 0°F (−18°C)
or colder, the engine coolant heater can help.
The vehicle will start easier and get better
fuel economy during engine warm-up. Usually, the
coolant heater should be plugged in a minimum
of four hours prior to starting the vehicle. At
temperatures above 32°F (0°C), use of the coolant
heater is not required. Your vehicle may also
have an internal thermostat in the plug end of the
cord. This will prevent operation of the engine
coolant heater when the temperature is at or above
0°F (−18°C) as noted on the cord.

The HUD will temporarily display CHECK TRIP
COMPUTER when there are messages on the DIC
trip computer.
The HUD will also display the following messages
when these systems, if the vehicle has them,
are active:
TRACTION CONTROL ACTIVE
STABILITY CONTROL ACTIVE
The HUD will temporarily display the TRACTION
CONTROL OFF message when the traction
control system is turned off.
The HUD will temporarily display the CRUISE SET
message when cruise control is activated or
cruise speed is increased.
Notice:If you try to use the HUD image as a
parking aid, you may misjudge the distance
and damage your vehicle. Do not use the HUD
image as a parking aid.
When the HUD is on, the speedometer reading
will continually be displayed. The current radio
station or CD track number will display for a short
period of time after the radio or CD track status
changes. This will happen whenever one of
the radio controls is pressed.The speedometer size will be reduced when radio,
CD information, warnings, or turn-by-turn
guidance information are displayed on the HUD.
The HUD control is
located on the console.
To adjust the HUD image so that items are
properly displayed, do the following:
1. Adjust the driver’s seat to a comfortable
position.
2. Start the engine.
3. Adjust the HUD controls.
Use the following settings to adjust the HUD.
9(Off):Turn the outer ring on the HUD control
to this position to turn the HUD off.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages
that may be on the vehicle. The pictures help
to 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 the 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 the vehicle’s functions. As
the details show on the next few pages, some
warning lights come on briey when the engine is
started just to indicate they are 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 the vehicle’s functions. Often
gages and warning lights work together to
indicate when there is a problem with the vehicle.
When one of the warning lights comes on and
stays on while the vehicle is being driven, or when
one of the gages shows there may be a problem,
check the section that tells you what to do
about it. Follow this manual’s advice. Waiting to
do repairs can be costly – and even dangerous.
So please get to know the vehicle’s warning lights
and gages. They can be a big help.
The vehicle also has a Driver Information
Center (DIC) that works along with the warning
lights and gages. SeeDriver Information
Center (DIC) on page 186for more information.

Low Tire Pressure Warning Light
This light should come
on briey as you start
the engine.
This light will also come on when one or more of
your tires is signicantly under-inated. Stop and
check your tires as soon as it is safe to do so.
If underinated, inate them to the proper pressure.
SeeTires on page 400for 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 409for more information.
Traction Control System (TCS)
Warning Light
If the vehicle has the
Traction Control
System (TCS), this light
may come on for the
following reasons:
The traction control button, located on the
center console, is pressed, turning the
system off. The light will stay on. To turn the
system back on, press the button again
and the warning light should go out. See
Traction Control System (TCS) on page 292
for more information.
If there is a brake system problem that is
specically related to traction control, the TCS
will turn off and the warning light will come on.
If the brakes begin to overheat, the TCS will
turn off and the warning light will come on until
the brakes cool down.
If the TCS warning light comes on and stays on
for an extended period of time when the system is
turned on, the vehicle needs service.
178

Engine Coolant Temperature Gage
The vehicle has a gage
that shows the engine
coolant temperature.
If the gage pointer moves into the shaded area,
the engine is too hot. That reading means
the engine coolant has overheated. If you have
been operating the vehicle under normal
driving conditions, you should pull off the road,
stop the vehicle, and turn off the engine as soon
as possible.
SeeCooling System on page 366for more
information.
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.
180

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,
transaxle, 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 336.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.
181

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
SeeGasoline Octane on page 338. Poor fuel
quality will cause your engine not to run as
efficiently as designed. You may notice this as
stalling after start-up, stalling when you put
the vehicle into gear, misring, hesitation on
acceleration, or stumbling on acceleration. (These
conditions may go away once the engine is
warmed up.) This will be detected by the system
and cause the light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at
least one full tank of the proper fuel to turn the
light off.
If none of the above steps have made the light
turn off, your dealer can check the vehicle.
Your dealer has the proper test equipment and
diagnostic tools to x any mechanical or electrical
problems that may have developed.Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have
or may begin programs to inspect the emission
control equipment on your vehicle. Failure to pass
this inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
check engine light is on or not working properly.
Your vehicle will not pass this inspection if
the OBD (on-board diagnostic) system determines
that critical emission control systems have not
been completely diagnosed by the system.
The vehicle would be considered not ready for
inspection. This can happen if you have recently
replaced your battery or if your battery has
run down. The diagnostic system is designed to
evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and
your vehicle still does not pass the inspection for
lack of OBD system readiness, your dealer
can prepare the vehicle for inspection.
183

Oil Pressure Light
If there is a problem
with the vehicle’s oil
pressure, this light may
stay on when the
engine is started.
It may also come on while the vehicle is being
driven. This indicates that the engine could be low
on oil or could have some other oil problem.
Have it xed right away.
The oil light could also come on in two other
situations:
When the ignition is on but the engine is not
running, the light will come on as a test to
indicate it is working. The light will go out when
the ignition is turned to RUN. If it does not come
on while the ignition is in the on position, there
may be a problem with the fuse or bulb. See
Fuses and Circuit Breakers on page 460.
If the brakes are applied quickly and the vehicle
makes a hard stop, the light may come on for a
moment. This is normal.
{CAUTION:
Do not keep driving if the oil pressure is
low. If you do, your engine can become so
hot that it catches re. You or others
could be burned. Check your oil as soon
as possible and have your vehicle
serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would
not be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.
