Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something
that could damage your vehicle.
A notice tells about something that can damage
the vehicle. Many times, this damage would not be
covered by your vehicle’s warranty, and it could
be costly. But the notice will tell what to do to help
avoid the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors
or in different words.
There are also warning labels on the vehicle. They
use the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along
with the text describing the operation or
information relating to a specic component,
control, message, gage, or indicator.
If you need help guring out a specic name of a

4. Snap the front and the back of the transmitter
together.
5. Test the operation of the transmitter with the
vehicle.
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
ON 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.During a remote start, if your vehicle has an
automatic climate control system and heated
seats, the heated seats will turn on during colder
outside temperatures and will shut off when
the key is turned to RUN. If your vehicle does not
have an automatic climate control system,
during remote start, you will need to manually turn
the heated seats on and off. See Heated Seats
for additional information
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.
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 (RKE) System on page 98for
additional information.
103

/(Remote Start):This button will be on the
RKE transmitter if you have remote start.
To start the vehicle using the remote start feature,
do the following:
1. Aim the transmitter at the vehicle.
2. Press and release the transmitter’s lock
button, then immediately press and hold
the transmitter’s remote start button until the
turn signal lights ash. If you cannot see
the vehicle’s lights, press and hold the remote
start button for at least four seconds. The
vehicle’s doors will lock. Pressing the remote
start button again, after the vehicle has
started, will turn off the ignition.
When the vehicle starts, the parking lamps will
turn on and remain on while the vehicle is
running.
3. If it is the rst remote start since the vehicle
has been driven, repeat these steps while the
engine is still running, to extend the time
by 10 minutes for the engine to continue to
run. Remote start can be extended one time.
After entering the vehicle during a remote start,
insert and turn the key to the ON position to drive
the vehicle.If the vehicle is left running it will automatically
shut off after 10 minutes unless a time extension
has been done.
To manually shut off a remote start, do any of the
following:
Aim the RKE transmitter at the vehicle and
press the remote start button until the
parking lamps turn off.
Turn on the hazard warning ashers.
Turn the ignition switch on and then off.
The vehicle can be remote started two separate
times between driving sequences. The engine will
run for 10 minutes after each remote start.
Or, you can extend the engine run time by another
10 minutes within the rst 10 minute remote
start time frame, and before the engine stops.
For example, if the lock button and then the remote
start buttons are pressed again after the vehicle has
been running for ve minutes, 10 minutes are
added, allowing the engine to run for 15 minutes.
The additional 10 minutes are considered a
second remote vehicle start.
104

Once two remote starts, or a single remote start
with one time extension has been done, the
vehicle must be started with the key.
After the key is removed from the ignition, the
vehicle can be remote started again.
The vehicle cannot be remote started if the key is
in the ignition, the hood is not closed, or if
there is an emission control system malfunction.
Also, the engine will turn off during a remote
vehicle start if the coolant temperature gets too
high or if the oil pressure gets low.
Vehicles that have the remote vehicle start feature
are shipped from the factory with the remote
vehicle start system enabled. The system may be
enabled or disabled through the DIC if your
vehicle has DIC buttons. See “REMOTE START”
underDIC Vehicle Customization (With DIC
Buttons) on page 255for additional information. If
your vehicle does not have DIC buttons, see
your dealer/retailer to enable or disable the remote
vehicle start system.Remote Start Ready
If your vehicle does not have the remote vehicle
start feature, it will have the remote start ready
feature. This feature allows your dealer/retailer to
add the manufacturer’s remote vehicle start
feature.
See your dealer/retailer if you would like to add
the manufacturer’s remote vehicle start feature to
your vehicle.

Changes or modications to this system by other
than an authorized service facility could void
authorization to use this equipment.
PASS-Key
®III+ uses a radio frequency
transponder in the key that matches a decoder in
your vehicle.
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 ON, ACCESSORY or START from the OFF
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 490. 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.
121

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.
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/retailer
for service.
3. After the engine has started, turn the key to
OFF, and remove the key.
4. Insert the new key to be programmed and
turn it to the ON position within ve seconds
of removing the original key.
5. The security light will turn off once the key
has been programmed.
6. Repeat Steps 1 through 5 if additional keys
are to be programmed.If you are driving and the security light comes on
and stays on, you may be able to restart your
engine. Your PASS-Key
®III+ system, however,
may not be working properly and must be serviced
by your dealer/retailer.
If you lose or damage your PASS-Key
®III+ key,
see your dealer/retailer or a locksmith who can
service PASS-Key
®III+ to have a new key made.
The SERVICE THEFT DETERRENT SYSTEM
message displays on the Driver Information Center
(DIC) when there is a problem with the
theft-deterrent system. SeeDIC Warnings and
Messages on page 244for additional information.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the
vehicle.

Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an
elaborate break-in. But it will perform better in
the long run if you follow these guidelines:
If you have all-wheel drive, keep your
speed at 55 mph (88 km/h) or less for
the rst 500 miles (805 km).
Do not drive at any one constant speed,
fast or slow, for the rst 500 miles
(805 km). Do not make full-throttle starts.
Avoid downshifting to brake, or slow,
the vehicle.
Avoid making hard stops for the rst
200 miles (322 km) or so. During this time
the new brake linings are not yet broken
in. Hard stops with new linings can
mean premature wear and earlier
replacement. Follow this breaking-in
guideline every time you get new brake
linings.
Do not tow a trailer during break-in. See
Towing a Trailer on page 371for the
trailer towing capabilities of your vehicle
and more information.
Following break-in, engine speed and load can
be gradually increased.
