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 3-57for 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. The rear window defogger will also turn on.
If your vehicle has heated seats, they may turn on during
colder outside temperatures and will shut off when the
key is turned to ON/RUN. You may not notice an increase
in seat surface temperature until the seat is occupied for
a short period of time.
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.
If your vehicle is low on fuel, do not use the remote
start feature. The vehicle may run out of fuel.If your vehicle has the remote start feature, the RKE
transmitter functions will have an increased range
of operation. However, the range may be less while
the vehicle is running.
There are other conditions which can affect the
performance of the transmitter, seeRemote Keyless
Entry (RKE) System on page 2-4for additional
information.
/(Remote Vehicle Start):This button will be on the
RKE transmitter if you have remote start.
To start the engine using the remote start feature:
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. Hold the remote 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.
When the vehicle’s engine starts, the parking lamps
will turn on and remain on while the engine is
running.

PASS-Key®III+ Electronic
Immobilizer Operation
Your vehicle has PASS-Key®III+ (Personalized
Automotive Security System) theft-deterrent system.
PASS-Key
®III+ is a passive theft-deterrent system.
The system is automatically armed when the key
is removed from the ignition.
The system is automatically disarmed when the key is
turned to ON/RUN, ACC/ACCESSORY or START from
the LOCK/OFF position.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem
with arming or disarming the theft-deterrent system.
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, there may be a problem with your theft-deterrent
system. 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 5-97. 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/retailer 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/retailer or a locksmith who can service
PASS-Key
®III+ to have keys made and programmed
to the system.
See your dealer/retailer 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.

Starting Procedure
1. With your foot off the accelerator pedal, turn the
ignition to START. When the engine starts, let go of
the key. The idle speed will slow down as the engine
warms. Do not race the engine immediately after
starting it. Operate the engine and transmission
gently to allow the oil to warm up and lubricate all
moving parts.
The vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the engine
and protects components. If the ignition key is turned
to the START position, and then released when the
engine begins cranking, the engine will continue
cranking for a few seconds or until the vehicle starts.
If the engine does not start and the key is held in
START, 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/
ACCESSORY or LOCK/OFF 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 let the cranking motor 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, repeat these steps. This clears
the extra gasoline from the engine. Do not race the
engine immediately after starting it. Operate the
engine and transmission gently until the oil warms up
and lubricates all moving parts.
Notice:The engine is designed to work with the
electronics in the vehicle. If you add electrical parts
or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer/retailer. If you do not, the
engine might not perform properly. Any resulting
damage would not be covered by the vehicle
warranty.
2-22

I (Intermediate):This position is also used for normal
driving. However, it reduces vehicle speed without using
the brakes for slight downgrades where the vehicle
would otherwise accelerate due to steepness of grade.
If constant upshifting or downshifting occurs while
driving up steep hills, this position can be used to
prevent repetitive types of shifts. You might choose
I (Intermediate) instead of D (Drive) when driving
on hilly, winding roads and when towing a trailer,
so that there is less shifting between gears.
L (Low):This position reduces vehicle speed more than
I (Intermediate) without actually using the brakes. You
can use it on very steep hills, or in deep snow or mud.
If the shift lever is placed in L (Low), the transmission
will not shift into L (Low) until the vehicle is going slowly
enough.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator pedal
may damage the transmission. The repair will not be
covered by the vehicle warranty. If you are stuck, do
not spin the tires. When stopping on a hill, use the
brakes to hold the vehicle in place.Transmission Overheating
If the transmission uid temperature rises above
284°F (140°C) or rises rapidly, the Engine Coolant
Temperature Warning Light will ash. SeeEngine
Coolant Temperature Warning Light on page 3-31for
more information. When the transmission overheats
it will go into a protection mode and will default shift into
fth gear if in the D (Drive) position, or second gear if
in the L (Low) 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 transmission will
return to the normal shift patterns. Towing or driving on
long hills can cause the transmission uid temperature
to be higher than normal. If the transmission uid
temperature will not cool, you may need to pull over and
check the transmission uid level. You should also
check the engine coolant temperature. If it is hot, see
Engine Overheating on page 5-28.
2-26

Transmission Overheating
If the transmission uid temperature rises above
270°F (132°C) or rises rapidly, the Engine Coolant
Temperature Warning Light will ash. SeeEngine
Coolant Temperature Warning Light on page 3-31for
more information. When the transmission overheats
it will go into a protection mode and will default into a
different shift sequence to help cool the transmission
uid. This shift sequence is the same for both D (Drive)
position and manual mode. 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
transmission will return to the normal shift patterns.
Towing or driving on long hills can cause the
transmission uid temperature to be higher than normal.
If the transmission uid temperature will not cool, you
may need to pull over and check the transmission
uid level. You should also check the engine coolant
temperature. If it is hot, seeEngine Overheating
on page 5-28.
2 (Second) and 3 (Third) Gear Start
Feature
When accelerating the vehicle from a stop in snowy
and icy conditions, you may want to select 2 (Second)
and 3 (Third) gear. A higher gear, and light application of
the gas pedal, may allow you to gain more traction on
slippery surfaces.
With the MSM (Manual Shift Mode), the vehicle can
accelerate from a stop in 2 (Second) or 3 (Third).
1. Move the shift lever from D (Drive) into the
manual gate.
2. With the vehicle stopped, move the shift lever
forward to select 2 (Second) or 3 (Third).
The vehicle will start from a stop position in
2 (Second) or 3 (Third).
3. Once the vehicle is moving select the desired drive
gear or move the shift lever to the D (Drive) position.
2-30

6. Remove the lter from the vehicle.
7. Install a new passenger compartment air lter.
For the type of lter to use seeMaintenance
Replacement Parts on page 6-13.
8. Reverse Steps 1 through 5.
Warning Lights, Gages, and
Indicators
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 prevent injury.
Warning lights come on when there may be or is a
problem with one of the vehicle’s functions. Some
warning lights come on briey when the engine is started
to indicate they are working.
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 a problem with
the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there
may be a problem, check the section that explains
what to do. Follow this manual’s advice. Waiting to do
repairs can be costly and even dangerous.
3-23

Airbag Readiness Light
There is an airbag readiness light on the instrument
panel cluster, which shows the airbag symbol.
The system checks the airbag’s electrical system for
malfunctions. The light tells you if there is an electrical
problem. The system check includes the airbag
sensor, the pretensioners, the airbag modules, the
wiring and the crash sensing and diagnostic module.
For more information on the airbag system, seeAirbag
System on page 1-58.
If the airbag readiness light stays on after you start
the vehicle or comes on when you are driving,
your airbag system may not work properly. Have your
vehicle serviced right away.{CAUTION:
If the airbag readiness light stays on after the
vehicle is started or comes on while driving, it
means the airbag system might not be working
properly. The airbags in the vehicle might not
inate in a crash, or they could even inate
without a crash. To help avoid injury, have the
vehicle serviced right away.
The airbag readiness light should ash for a few seconds
when you start the engine. If the light does not come on
then, have it xed immediately. If there is a problem with
the airbag system, an airbag Driver Information Center
(DIC) message may also come on. SeeDIC Warnings
and Messages on page 3-49for more information.
3-27

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
For vehicles with a tire
pressure light, this light
comes on briey when the
engine is started and
provides information about
tire pressures and the
Tire Pressure Monitoring
System.
When the Light is On Steady
This indicates that one or more of the tires is signicantly
underinated.
A tire pressure message in the Driver Information Center
(DIC), can accompany the light. SeeDIC Warnings and
Messages on page 3-49for more information. Stop and
check the tires as soon as it is safe to do so. If a tire is
underinated, inate to the proper pressure. SeeTires
on page 5-52for more information.
When the Light Flashes First and Then is
On Steady
This indicates that there could be a problem with the
Tire Pressure Monitor System. The light ashes for
about a minute and stays on steady for the remainder of
the ignition cycle. This sequence repeats with every
ignition cycle. SeeTire Pressure Monitor System
on page 5-61for more information.
3-32

Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation
of the fuel, ignition, and emission control systems.
It ensures that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment.
This light should come on
when the ignition is on, but
the engine is not running,
as a check to show it
is working. If it does not,
have the vehicle serviced
by your dealer/retailer.
If the check engine light comes on and stays on, while
the engine is running, this indicates that there is an
OBD II problem and service is required.Malfunctions often are indicated by the system before
any problem is apparent. Being aware of the light
can prevent more serious damage to the vehicle.
This system assists the service technician in correctly
diagnosing any malfunction.
Notice:If the vehicle is continually driven with this
light on, after a while, the emission controls might
not work as well, the vehicle’s fuel economy might
not be as good, and the engine might not run as
smoothly. This could lead to costly repairs that
might not be covered by the vehicle warranty.
Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system of the
vehicle or the replacement of the original tires with
other than those of the same Tire Performance
Criteria (TPC) can affect the vehicle’s emission
controls and can cause this light to come on.
Modications to these systems could lead to
costly repairs not covered by the vehicle warranty.
This could also result in a failure to pass a required
Emission Inspection/Maintenance test. See
Accessories and Modifications on page 5-3.
3-33

Make sure to fuel the vehicle with quality fuel.
Poor fuel quality causes the engine not to run
as efficiently as designed and can cause: stalling
after start-up, stalling when the vehicle is changed
into gear, misring, hesitation on acceleration,
or stumbling on acceleration. These conditions
might go away once the engine is warmed up.
If one or more of these conditions occurs, change
the fuel brand used. It will require at least one
full tank of the proper fuel to turn the light off.
SeeGasoline Octane on page 5-5.
If none of the above have made the light turn off, your
dealer/retailer can check the vehicle. The dealer/retailer
has the proper test equipment and diagnostic tools to
x any mechanical or electrical problems that might
have developed.Emissions Inspection and
Maintenance Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on the vehicle. Failure to pass this inspection
could prevent getting a vehicle registration.
Here are some things to know to help the vehicle pass
an inspection:
The vehicle will not pass this inspection if the check
engine light is on with the engine running, or if the
key is in ON/RUN and the light is not on.
The vehicle will not pass this inspection if the
OBD II (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 the battery has recently
been replaced or if the battery has run down.
The diagnostic system is designed to evaluate
critical emission control systems during normal
driving. This can take several days of routine
driving. If this has been done and the vehicle still
does not pass the inspection for lack of OBD II
system readiness, your dealer/retailer can prepare
the vehicle for inspection.
