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:

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 1-4and
Heated and Cooled Seats on page 1-5for additional
information. When the remote start system is active, the
climate control system will heat and cool the inside of
the vehicle based on the outside temperature. The rear
window defogger will be turned on by the climate
control system when it is heating the inside of the
vehicle. 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 keyless entry
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 System on page 2-5for additional information.
/(Remote Start):Press and release the lock button
and then press and hold the remote start button to
start the vehicle.
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.
3. When the vehicle starts, the parking lamps will turn
on and remain on while the vehicle is running.
4. If it is your rst remote start since last driving,
repeat these steps while the engine is still
running for a 10 minute time extension. Remote
start can be extended one time.
2-9

When you want to open a rear door when the security
lock is on, do the following:
1. Unlock the door using the remote keyless entry
transmitter, if the vehicle has one, the power
door lock switch, or by lifting the rear door
manual lock.
2. Open the door from the outside.
To cancel the rear door security lock, do the following:
1. Unlock the door and open it from the outside.
2. Insert the key into the security lock slot and turn it
so the slot is in the vertical position.
Lockout Protection
If the key is in the ignition and the power door lock
switch is used to lock the doors, all doors will lock and
then the driver’s door will unlock. It is always
recommended that you remove the ignition key when
locking your vehicle.
The lockout protection feature can be overridden by
holding the power door lock switch for three seconds or
longer.
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 2-31.
2-14

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 under
Engine Exhaust on page 2-31.
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. See
Winter Driving on page 4-24.
{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 2-29.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer on page 4-36.
2-32

Outside Convex Mirror
The passenger’s side mirror is convex. A convex
mirror’s surface is curved so more can be seen from the
driver’s seat.
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.
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 3-23orDual Automatic Climate Control
System on page 3-26for 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. See
Turn and Lane-Change Signals on page 3-7for more
information.

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 automatically
cool the vehicle if the temperature is greater than
90°F (32°C) and heat the vehicle if the temperature is
below 37°F (3°C). If the temperature is between
37°F (3°C) and 90°F (32°C), the last control setting
selected when the engine was running will be used.
Normal operation and the last setting of the climate
control system will return after the ignition key is turned
to the C (RUN) position. SeeRemote Keyless Entry
System Operation on page 2-6for more information.
Operation
(
(Off):Turn the left knob to this position to turn the
climate control system off.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
The fan speed will be temporarily reduced between
the transition to a new mode. The fan will resume when
the new mode is complete.
If the airow seems low when the fan speed is at the
highest setting, the passenger compartment air lter may
need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-31and
Scheduled Maintenance on page 6-4.
Temperature Control:Turn the center knob clockwise
or counterclockwise to warm or cool the air coming
through the outlets.
Use the right knob to select from the following modes:
H(Vent):This mode directs outside air to the
instrument panel outlets. If driving in city traffic, and the
vehicle is stopped and idling, or the weather is hot,
turn on the recirculation mode.
)(Bi-Level):This mode directs half of the air to the
instrument panel outlets, and the remaining air to
the oor outlets. Slightly cooler air is directed to the
instrument panel outlets and warmer air is directed to
the oor outlets.
3-23

6(Floor):This mode directs most of the air to the
oor outlets with some air directed toward the side
window outlets and a little air directed to the windshield.
In this mode, the system will automatically use
outside air.
If recirculation is selected, it will stay on for three minutes
to reduce windshield fogging. The led will come on.
You can also select modes by using the following
buttons:
h(Recirculate):Press this button to recirculate
cabin air through the vehicle. It can be used to prevent
outside air and odors from entering your vehicle or
to help heat or cool the air inside your vehicle more
quickly. An indicator light below the button will come on
in this mode. Operation in this mode during periods
of high humidity and cool outside temperatures
may result in increased window fogging. If window
fogging is experienced, select the defrost mode.
#(Air Conditioning):Press this button to turn the air
conditioning system on or off. When this button is
pressed, an indicator light below the button will come on
to let you know the air conditioning is activated. Air
conditioning can be selected in any mode as long as the
fan knob is not in the off position. When in defrost
and defog the air-conditioning compressor will come on
automatically.On hot days during the vehicle’s initial start-up, open
the windows to let hot inside air escape; then close
them. This helps to reduce the time it takes for
the vehicle to cool down. It also helps the system to
operate more efficiently.
For quicker cool down on hot days, do the following:
1. Select the vent air mode.
2. Select the recirculation mode.
3. Select the air conditioner.
4. Select the coolest temperature.
5. Select the highest fan speed.
The air-conditioning system removes moisture from the
air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.
Defogging and Defrosting
Fog on the inside of the vehicle is a result of high humidity
causing moisture to condense on the cool window glass.
This can be minimized if the climate control system is
used properly. There are two modes to clear frost or fog
from the windshield. Use the defog mode to clear the
windows of condensation and to warm the vehicle’s
occupants. Use the defrost mode to remove frost or
condensation from the windshield quickly. Recirculation
cannot be selected when in these modes (the indicator
light will come on when pressed).
