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 207
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 429.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.

If the engine does not start and the key is held
in START for many seconds, cranking will be
stopped after 15 seconds to prevent cranking
motor damage. To prevent gear damage, this
system also prevents cranking if the engine is
already running. Engine cranking can be
stopped by turning the ignition switch to
the ACC or LOCK position.
Notice:Cranking the engine for long periods
of time, by returning the key to the START
position immediately after cranking has ended,
can overheat and damage the cranking motor,
and drain the battery. Wait at least 15 seconds
between each try, to allow the cranking motor
to cool down.
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.

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 181for 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 355.
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.

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 198for more information.
Brake System Warning Light
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.
If the brake system warning light comes on, there
is a brake problem. Have your brake system
inspected right away.
The brake light is located in the instrument panel
cluster.

Engine Coolant Temperature Gage
This gage measures
the temperature of
the vehicle’s engine.
If the indicator needle moves into the shaded
area, the engine is too hot. A temperature indicator
light will turn on.
If you have been operating your vehicle under
normal driving conditions, and the temperature
indicator 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 382for 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 391
for 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.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 333.
183

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.
184

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 337.
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 335. 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.
