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
component, gage, or indicator, reference the
following topics:

3. Slide the new battery into the transmitter with
the positive side of the battery facing down.
Use a type CR2032 battery, or equivalent
type. Make sure the cover is on tightly,
so water will not get in.
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
RUN 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 controlsystem, 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.
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.
Do not use the remote start feature if your vehicle
is low on fuel. Your vehicle may run out of fuel.
The keyless entry 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 System on page 112for additional
information.
/(Remote Start):Press and release the lock
button and then press and hold the remote
start button to start the vehicle.
117

If the passenger’s side power door lock switch is
pressed when the front passenger’s door is
open and the key is in the ignition, all of the doors
will lock and then the front passenger’s door
will unlock.
Liftgate/Liftglass
{CAUTION:
It can be dangerous to drive with the
liftglass or liftgate open because carbon
monoxide (CO) gas can come into your
vehicle. You cannot see or smell CO. It
can cause unconsciousness and even
death.
CAUTION: (Continued)
CAUTION: (Continued)
If you must drive with the liftglass or
liftgate open, or if electrical wiring or
other cable connections must pass
through the seal between the body and
the liftglass or liftgate:
Make sure all other windows are shut.
Turn the fan on your heating or
cooling system to its highest speed
with the recirculation mode off. That
will force outside air into your vehicle.
SeeClimate Control System on
page 210orDual Automatic Climate
Control System on page 213.
If you have air outlets on or under the
instrument panel, open them all
the way.
If your vehicle has a power liftgate,
disable the power liftgate function.
SeeEngine Exhaust on page 155.
If your vehicle has a power liftgate, seePower
Liftgate on page 125.
123

It is not recommended that you drive with the
liftgate open, however, if you must drive with the
liftgate open, the power liftgate should be switched
to manual liftgate operation — the overhead
console switch set to the “Disable” position.
Both the liftglass and liftgate have an electric latch.
If the battery is disconnected or has low voltage,
the liftglass and liftgate will not open. The
liftglass and liftgate will resume operation when
the battery is reconnected and charged.
If the battery is properly connected and has
adequate voltage, and the liftgate or liftglass still
will not function, your vehicle should be taken to a
dealership for service.
{CAUTION:
It can be dangerous to drive with the
liftglass or liftgate open because carbon
monoxide (CO) gas can come into your
vehicle. You cannot see or smell CO.
It can cause unconsciousness and even
death.

Power Running Boards
Your vehicle may have power running boards.
These make getting into and out of the vehicle
easier.
The power running boards activate when either
door on the driver’s or passenger’s side is opened
or closed. They automatically extend from
beneath the vehicle on the side in which the door
has been opened. Once the door is closed, the
running boards will automatically move back under
the vehicle. The vehicle must be stationary for
the running boards to extend or retract.The switch used to
disable the power
running boards is
located on the center
console below the
climate control system.
The running boards cannot be disabled in the
extended position.
129

Adjustable Throttle and Brake Pedal
If your vehicle has this feature, you can change
the position of the throttle and brake pedals.
The switch used to
adjust the pedals is
located on the center
console below the
climate control system.
Press the arrow at the bottom of the switch to
move the pedals closer to your body. Press
the arrow at the top of the switch to move the
pedals away from your body.
This feature is designed for shorter drivers, since
the pedals can not move farther away from
the standard position, but can move toward the
driver for better pedal reach.No adjustment to the pedals can be made when
the vehicle is in REVERSE (R) or while using
the cruise control.
Your vehicle may have a memory function which
allows pedal settings to be saved and recalled.
SeeMemory Seat, Mirrors, and Pedals on
page 13for more information.
Engine Coolant Heater
Your vehicle may have an engine coolant heater.
In very cold weather, 0°F (−18°C) or colder,
the engine coolant heater can help. You will get
easier starting and better fuel economy during
engine warm-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your vehicle.
At temperatures above 32°F (0°C), use of the
coolant heater is not required. Your vehicle may
also have an internal thermostat in the plug end of
the cord. This will prevent operation of the engine
coolant heater when the temperature is at or above
0°F (−18°C) as noted on the cord.
140

Running the Engine While Parked
It is better not to park with the engine running. But if
you ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust
into your vehicle. See the earlier caution
underEngine Exhaust on page 155.
Also, idling in a closed-in place can let
deadly carbon monoxide (CO) into your
vehicle even if the climate control fan is at
the highest setting. One place this can
happen is a garage. Exhaust — with
CO — can come in easily. NEVER park in
a garage with the engine running.
Another closed-in place can be a blizzard.
SeeWinter Driving on page 384.
{CAUTION:
It can be dangerous to get out of your
vehicle if the shift lever is not fully in
PARK (P) with the parking brake rmly
set. Your vehicle can roll. Do not leave
your vehicle when the engine is running
unless you have to. If you have left the
engine running, the vehicle can move
suddenly. You or others could be injured.
To be sure your vehicle will not move,
even when you are on fairly level ground,
always set your parking brake and move
the shift lever to PARK (P).
