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:

Heated Seats
Your vehicle may have this feature. If it does, the
heated seat buttons are located on the climate
control panel.
This feature will heat the lower cushions of the
driver’s and front passenger’s seats.
Press this button once
to turn the heated seat
on to the high setting.
Both indicator lights next to the heated seat
symbol will be lit to indicate that it is on the high
setting. Press the button a second time to go to the
low setting. One indicator will be lit. Press the
button a third time to turn the heated seat off.This feature will turn off automatically when the
ignition is turned off.
Memory Seat
If your vehicle has this
feature, the controls for
the memory function
are located on the
driver’s door.
These buttons are used to program and recall
memory settings for the driver’s seating position.
The settings for these features can be
personalized for both driver 1 and driver 2.
Driver 1 or driver 2 corresponds to the memory
buttons labeled 1 and 2 on the driver’s door and to
the numbers, 1 or 2, on the back of the remote
keyless entry transmitters.

{CAUTION:
It can be dangerous to drive with the
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. If you
must drive with the liftgate open or if
electrical wiring or other cable
connections must pass through the seal
between the body and the liftgate:
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 on page 193
orDual Climate Control System on
page 197.
If you have air outlets on or under the
instrument panel, open them all the
way. SeeEngine Exhaust on page 141.To close the liftgate, pull down on the handle, then
rmly shut the liftgate. Do not drive with the
liftgate open, even slightly.
120

DRIVE (D):This position is for normal driving. It
provides the best fuel economy for your vehicle. If
you need more power for passing, and you are:
Going less than 35 mph (55 km/h), push
your accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push
the accelerator all the way down.
The vehicle will shift down to the next gear
and have more power.
Downshifting the transaxle in slippery road
conditions could result in skidding, see Skidding
underLoss of Control on page 362
Notice:If your vehicle seems to start up
rather slowly or not shift gears when you go
faster, and you continue to drive your vehicle
that way, you could damage the transaxle.
Have your vehicle serviced right away. You can
drive in SECOND (2) when you are driving
less than 35 mph (55 km/h) and DRIVE (D) for
higher speeds until then.
Warm-Up Shift
Your vehicle has a computer controlled transaxle
designed to warm up the engine faster when
the outside temperature is 35°F (2°C) or colder.
You may notice that the transaxle will shift at
a higher vehicle speed until the engine is warmed
up. This is a normal condition designed to
provide heat to the passenger compartment and
defrost the windows more quickly. SeeClimate
Control System on page 193andDual Climate
Control System on page 197for more information.
THIRD (3):This position is also used for normal
driving. It reduces vehicle speed more than
DRIVE (D) without using your brakes. You might
choose THIRD (3) instead of DRIVE (D) when
driving on hilly, winding roads, when towing
a trailer, so there is less shifting between gears
and when going down a steep hill.
135

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 141.
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 373.
{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 138.
If you are pulling a trailer, seeTowing a Trailer on
page 386.
142

Outside Convex Mirror
{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.The passenger’s side mirror is convex. A convex
mirror’s surface is curved so more can be
seen from the driver’s seat. It also makes things
appear farther away than they really are.Outside Heated Mirrors
The outside rearview mirrors will heat to help clear
them of ice, snow, and condensation when the rear
window defogger is turned on. See “Rear Window
Defogger” inClimate Control System on page 193
orDual Climate Control System on page 197.

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 Battery
Voltage Low. If this message is displayed, it is
recommended that the driver reduce the electrical
loads as much as possible.Battery Run-Down Protection
Your vehicle has a feature to help prevent you
from draining the battery, in case you accidentally
leave the interior lamps on. If you leave any
interior lamps on while the ignition is in lock or off,
they will automatically turn off after 10 minutes.
The lamps will not come back on again until
you do one of the following:
Turn the ignition to RUN or ACCESSORY
Open a closed door, or close and reopen
a door.
Turn the interior lamps on if they are in the
door or override position.
Turn the interior lamps to the door or override
position and then to on again if the interior
lamp control is in the on position.
If your vehicle has less than 15 miles (25 km)
on the odometer, the battery saver will turn off
the lamps after only three minutes.
