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

Section 2 Features and Controls

Remote Vehicle Start
The remote vehicle starting feature allows you to
start the engine from outside of the vehicle. It
also starts up the vehicle’s automatic climate
control system. When the remote start system is
active, the climate control system will heat
and cool the inside of the vehicle according to the
previous settings of the system before turning
the vehicle off. The rear window defogger will be
turned on by the climate control system when
it is cold outside. If the vehicle has heated seats,
they will also turn on. SeeHeated and Cooled
Seats on page 11for additional information.
Cooled seats are not activated during a remote
start. Normal operation of the climate control
system will return after the key is turned to RUN.
SeeDual Climate Control System on page 210.
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.
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.
There are other conditions which can affect the
performance of the transmitter, see “Remote
Keyless Entry System Operation” listed previously
for additional information.
/(Remote Start):Press and release the lock
button and then press and hold this button to use
the remote start feature.
100

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 or if the vehicle’s
lights are not visible, 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 engine
running time by 10 minutes. Remote start
can be extended one time.
After entering the vehicle during a remote start,
insert and turn the key to RUN 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 remote vehicle start feature provides two
separate starts, each with 10 minutes of engine
running, or it provides one start with 10 minutes of
engine running that may be extended 10 more
minutes. If you press and release the transmitter
lock button and then press and hold the remote
start button on the RKE transmitter again before the
rst 10 minutes of engine running time has expired,
10 minutes are added to the remaining minutes. For
example, if the lock button and then the remote
start buttons are pressed again after ve minutes of
the engine run time, 10 minutes are added and you
now have 15 minutes of engine running. The added
ten minutes are considered a second remote
vehicle start.
Once two remote starts or a single start with a
time extension have been used, the vehicle must
be started with the ignition key before you can
use the remote start feature again.
101

The remote vehicle start feature will not operate if
the key is in the ignition, the hood is not closed,
or if there is an emission control system
malfunction.
The engine will turn off during a remote vehicle
start if the coolant temperature gets too high,
or the oil pressure is too low.
Your vehicle was shipped from the factory with the
remote vehicle start system enabled. The
system may be disabled through the Driver
Information Center (DIC). See “REMOTE START”
underDIC Vehicle Customization on page 259
for additional information.
SeeEngine Exhaust on page 130for important
safety information when using remote start
in a closed garage.
Remote Start Ready
If your vehicle does not have the remote vehicle
start feature, it may have the remote start
ready feature. This feature allows your dealer to
add the manufacturer’s remote vehicle start
feature. See your dealer if you would like to add
the manufacturer’s remote vehicle start feature
to your vehicle.
Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers, especially children, can
easily open the doors and fall out of a
moving vehicle. When a door is
locked, the handle will not open it.
You increase the chance of being
thrown out of the vehicle in a crash if
the doors are not locked. So, wear
safety belts properly and lock the
doors whenever you drive.
CAUTION: (Continued)
102

Trunk
{CAUTION:
It can be dangerous to drive with the
trunk lid open because carbon monoxide
(CO) gas can come into your vehicle. You
cannot see or smell CO. It can cause
unconsciousness and even death. If you
must drive with the trunk lid open or if
electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or
cooling system to its highest speed
and select the control setting that will
force outside air into your vehicle. See
Climate Control System.
If you have air outlets on or under
the instrument panel, open them all
the way.
SeeEngine Exhaust on page 130.
Remote Trunk Release
G
(Remote Trunk Release):The remote trunk
release button is located to the left of the
steering wheel next to the instrument panel
brightness control. Press the button to open the
trunk. To use this feature, your vehicle must be in
PARK (P) or NEUTRAL (N) and the valet
lockout switch must be off.
You can also press the button with the trunk
symbol on the remote keyless entry transmitter to
open the trunk. To disable this feature, see
Valet Lockout Switch on page 112.

PASS-Key®III+
The PASS-Key®III+ system operates on a radio
frequency subject to Federal Communications
Commission (FCC) Rules and with Industry
Canada.
This device complies with Part 15 of the FCC
Rules. Operation is subject to the following
two conditions:
1. This device may not cause harmful
interference.
2. This device must accept any interference
received, including interference that may
cause undesired operation.
This device complies with RSS-210 of Industry
Canada. Operation is subject to the following
two conditions:
1. This device may not cause interference.
2. This device must accept any interference
received, including interference that may
cause undesired operation of the device.
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 insert or remove
the key from the ignition or transition the key from
RUN, 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
comes on when trying to start the vehicle, the
key may have a damaged transponder. Turn the
ignition off and try again.
115

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 452.Ifthe
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.To program the new key:
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 RUN position within
ve seconds of removing the original key.
The security light will turn off once the key has
been programmed.
5. Repeat Steps 1 through 4 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.
116

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.
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:
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 342for the
trailer towing capabilities of your vehicle
and more information.
Following break-in, engine speed and load can
be gradually increased.
117

Ignition Positions
With the ignition key in the ignition, the key can be
turned to four different positions:
Notice:Using a tool to force the key from the
ignition switch could cause damage or
break the key. Use the correct key and turn the
key only with your hand. Make sure the key
is in all the way. If none of this works,
then your vehicle needs service.A (OFF):This is the only position in which the
ignition key can be inserted or removed. This
position locks the ignition and transaxle. It is a
theft-deterrent feature.
B (ACCESSORY):This position lets the radio and
windshield wipers operate while the engine is
off. To use ACCESSORY, turn the key clockwise.
C (RUN):This position is where the key returns
to after the vehicle is started. This position displays
some of the warning and indicator lights.
The battery could be drained if you leave the key
in the ACCESSORY or RUN position with the
engine off. You may not be able to start your
vehicle if the battery is allowed to drain for
an extended period of time.
D (START):This position starts the engine.
A warning chime will sound and the Driver
Information Center (DIC) will display DRIVER
DOOR OPEN when the driver’s door is opened if
the ignition is in OFF, ACCESSORY and the
key is in the ignition. SeeDIC Warnings
and Messages on page 246for more information.
