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 the vehicle. It may also start the vehicle’s
heating or air conditioning systems, rear window
defogger, and heated seats. SeeHeated Seats on
page 11andHeated and Cooled Seats on page 12
for additional information. When the remote start
system is active, the climate control system will
heat or cool the inside of the vehicle at the setting
the vehicle was set to when the vehicle was last
turned 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 may
also turn on. Cooled seats are not activated during
a remote start. Normal operation of the system will
return after the key is turned to the RUN position.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.
If your vehicle has remote start, the RKE transmitter
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 94for
additional information.
/(Remote Start):If your vehicle has the remote
start feature, the RKE transmitter will have a
button with this symbol on it.

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 127.
Remote Trunk Release
The remote trunk
release button is located
in the glovebox.
Press the button to open the trunk. To use this
feature, your vehicle must be in PARK (P)
or NEUTRAL (N).
You can also press the remote trunk release
button on the Remote Keyless Entry (RKE)
transmitter to open the trunk. SeeRemote Keyless
Entry (RKE) System Operation on page 95.
106

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 127.
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 302.
{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).
Follow the proper steps to be sure your vehicle
will not move. SeeShifting Into Park (P) on
page 123.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer on page 315.
128

Outside Automatic Dimming
Heated Mirror
If you have this feature, the outside driver’s mirror
will adjust for the glare of headlamps behind you.
When you operate the rear window defogger, the
heated driver’s and passenger’s outside rearview
mirrors are warmed to help clear them of ice and
snow. See “Rear Window Defogger” underClimate
Control System on page 182orDual Automatic
Climate Control System on page 186for more
information.
Your vehicle may also have a turn signal indicator
on the mirror. An arrow on the outside rearview
mirror will ash in the direction of the turn or lane
change. SeeTurn and Lane-Change Signals
on page 162for more information.

Electric Power Management
The vehicle has Electric Power Management
(EPM) that estimates the battery’s temperature and
state of charge. It then adjusts the voltage for
best performance and extended life of the battery.
When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage or voltage
display on the Driver Information Center (DIC),
you may see the voltage move up or down. This
is normal. If there is a problem, an alert will
be displayed.
The battery can be discharged at idle if the
electrical loads are very high. This is true for all
vehicles. This is because the generator (alternator)
may not be spinning fast enough at idle to produce
all the power that is needed for very high electrical
loads.A high electrical load occurs when several of the
following loads are on: headlamps, high beams, fog
lamps, rear window defogger, climate control fan at
high speed, heated seats, engine cooling fans,
trailer loads, and loads plugged into accessory
power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s
output and the vehicle’s electrical needs. It can
increase engine idle speed to generate more
power, whenever needed. It can temporarily
reduce the power demands of some accessories.
Normally, these actions occur in steps or levels,
without being noticeable. In rare cases at the
highest levels of corrective action, this action
may be noticeable to the driver. If so, a Driver
Information Center (DIC) message might be
displayed, such as Battery Saver Active or Service
Battery Charging System. If this message is
displayed, it is recommended that the driver
reduce the electrical loads as much as possible.
SeeDIC Warnings and Messages on page 221.

Ashtray(s) and Cigarette Lighter
Push down on the front center tray to reveal the
front ashtray, cigarette lighter, and accessory
power outlet. The ashtray can be removed
for cleaning. Hold the sides of the ashtray
and then pull the ashtray up and out.
Notice:If you put papers, pins, or other
ammable items in the ashtray, hot cigarettes
or other smoking materials could ignite
them and possibly damage your vehicle.
Never put ammable items in the ashtray.
To use the lighter, push the center all the way in
and let it go. When it is ready, the center will
pop back out by itself. Pull out the entire unit to
use it.
Notice:Holding a cigarette lighter in while it
is heating will not allow the lighter to back
away from the heating element when it is hot.
Damage from overheating may occur to the
lighter or heating element, or a fuse could be
blown. Do not hold a cigarette lighter in
while it is heating.
Climate Controls
Climate Control System
With this system you can control the heating,
cooling, and ventilation for your vehicle.
If your vehicle has the remote start feature and it is
activated, the climate control system will heat and
cool the inside of the vehicle, using the previous
system settings before the vehicle was turned 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.
Cooled seats are not activated during a remote
start. Normal operation of the system will return
after the key is turned to the RUN position. See
Remote Keyless Entry (RKE) System Operation on
page 95for more information.
