Remote Vehicle Start
Your vehicle may have the remote start feature.
This feature allows you to start the engine
from outside the vehicle. See “REMOTE START”
underDIC Vehicle Personalization on page 210
for instructions on how to enable and disable this
feature.
During a remote start, the climate control system
will turn on at the fan, temperature, and mode
settings the vehicle was set to when the vehicle
was last turned off and will also turn on the
rear window defogger.
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):Press and release
the lock button and then press and hold the remote
vehicle start button to start the vehicle.
Your 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.
If your vehicle is low on fuel, do not use the remote
start feature. The vehicle may run out of fuel.
To start the engine using the remote start feature,
do the following:
1. Aim the RKE transmitter, that has a remote
vehicle start button, at the vehicle.
2. Press and release the transmitter’s lock
button, then immediately press and hold
the remote vehicle start button until the
vehicle’s turn signal lamps ash, or for at
least four seconds, if the vehicle’s lights are
not visible. The vehicle’s doors will be locked.
Pressing the remote start button again after the
vehicle has started will turn off the ignition.

PASS-Key®III+ Operation
Your vehicle has PASS-Key®III+ (Personalized
Automotive Security System) theft-deterrent
system. PASS-Key
®III+ is a passive
theft-deterrent system. This means you do not
have to do anything special to arm or disarm the
system. It works when you transition the key
to RUN, ACC or START from the LOCK position.
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 431. If the 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.

Transaxle Overheating
If the transaxle uid temperature rises above
284°F (140°C) or rises rapidly, the Engine Coolant
Temperature Warning Light will ash. See
Engine Coolant Temperature Warning Light on
page 182for more information. When the transaxle
overheats it will go into a protection mode and
will default shift into fth gear if in the DRIVE (D)
position, or second gear if in the LOW (L)
position. Continue driving the vehicle in either
position depending on the required vehicle speed
and load. Once the uid temperature lowers to
the normal temperature range, the transaxle
will return to the normal shift patterns. Towing or
driving on long hills can cause the transaxle
uid temperature to be higher than normal. If the
transaxle uid temperature will not cool, you
may need to pull over and check the transaxle
uid level. You should also check the engine
coolant temperature. If it is hot, seeEngine
Overheating on page 360.
Parking Brake
The parking brake lever is located to the right of
the driver’s seat.
To set the parking brake, hold the brake pedal
down and pull up on the parking brake lever. If the
ignition is on, the brake system warning light will
come on.
To release the parking brake, hold the brake pedal
down. Pull the parking brake lever up until you can
press the release button. Hold the release button in
as you move the brake lever all the way down.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages
that may be 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 following
pages, some warning lights come on briey when
you start the engine just to let you know 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 your vehicle’s functions. Often
gages and warning lights work together to let you
know when there is 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 are a big help.

If the word OFF or the off symbol is lit on the
airbag status indicator, it means that the
passenger sensing system has turned off the right
front passenger’s frontal airbag. SeePassenger
Sensing System on page 82for more on this,
including important safety information.
If, after several seconds, all status indicator lights
remain on, or if there are no lights at all, there
may be a problem with the lights or the passenger
sensing system. See your dealer for service.
{CAUTION:
If the off indicator and the airbag
readiness light ever come on together, it
means that something may be wrong with
the airbag system. If this ever happens,
have the vehicle serviced promptly,
because an adult-size person sitting in the
right front passenger seat may not have
the protection of the frontal airbag. See
Airbag Readiness Light on page 176.
Battery Warning Light
The battery warning light
will come on briey as a
check, when you turn on
the ignition. Then it
should go out when the
engine is started.
If the light does not come on when you start your
vehicle, have your vehicle serviced right away.
This condition may indicate your battery warning
light is not functioning properly. If this light
comes on while you are driving, be sure to turn off
accessories such as the radio and climate
control system. Have your vehicle serviced right
away. The SERVICE BATTERY CHARGING
SYSTEM message may also appear in the Driver
Information Center. SeeDIC Warnings and
Messages on page 200for more information.
179

Engine Coolant Temperature Gage
This gage measures the
temperature of the
vehicle’s engine.
If the indicator needle moves towards the shaded
in thermostat, the engine is too hot. The engine
coolant temperature warning light will turn on. See
Engine Coolant Temperature Warning Light on
page 182for more information.
If you have been operating your vehicle under
normal driving conditions, and the engine coolant
temperature warning light comes on, you
should pull off the road, stop your vehicle and turn
off the engine as soon as possible.
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.
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 386for 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 395
for more information.
183

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,
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 339.

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
possible
If 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.
185

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 343.
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.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The
condition will usually be corrected when the
electrical system dries out. A few driving trips
should turn the light off.Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
SeeGasoline Octane on page 341. 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.
186

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.
Oil Pressure Light
If you have a low engine
oil pressure problem,
this light will stay on after
you start your engine, or
come on when you are
driving.
This indicates that your engine is not receiving
enough oil.
The engine could be low on oil, or could have
some other oil problem. Have it xed immediately.
The oil light could also come on in three other
situations:
When the ignition is on but the engine is not
running, the light will come on as a test to
show you it is working, but the light will go out
when you turn the ignition to START. If it
does not come on with the ignition on,
you may have a problem with the fuse or bulb.
Have it xed right away.
