Running the Vehicle 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 a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains Carbon
Monoxide (CO) which cannot be seen or smelled.
It can cause unconsciousness and even death.
Never run the engine in an enclosed area that
has no fresh air ventilation. For more information,
seeEngine Exhaust on page 2-45.
{CAUTION:
It can be dangerous to get out of the vehicle

The vehicle can roll. Do not leave the 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 the vehicle will not move, even when
you are on fairly level ground, always set the
parking brake and move the shift lever to P (Park).
{CAUTION:
Full-time four-wheel drive vehicles with the transfer
case in (N) Neutral will allow the vehicle to roll,
even if the automatic transmission shift lever is in
P (Park). So, be sure the transfer case is in a
drive gear — not in (N) Neutral. Always set the
parking brake.
Follow the proper steps to be sure the vehicle will not
move. SeeShifting Into Park on page 2-43.

Mirrors
Automatic Dimming Rearview Mirror
The vehicle has an automatic dimming rearview

Your vehicle may also have a Rear Vision Camera.
SeeRear Vision Camera (RVC) on page 2-50for more
information.
Cleaning the Mirror
Do not spray glass cleaner directly on the mirror.
Use a soft towel dampened with water.
Outside Power Foldaway Mirrors
If your vehicle has outside
power foldaway mirrors,
the controls are located on
the driver’s door armrest.
Mirror Adjustment
1. Press (A) or (B) to select the driver or passenger
side mirror.
2. Press one of the four arrows located on the control
pad to move the mirror to the desired position.
3. Adjust each outside mirror so that a little of the
vehicle and the area behind can be seen.
2-47

4. Press (C), to fold the mirrors out to the driving
position.
5. Press (D) to fold the mirrors in to the folded
position.
If the mirrors are accidentally folded/unfolded manually,
they may shake or utter at normal driving speeds
and may not stay in the unfolded position. If this
happens, you will need to reset the mirrors.
See “Resetting the Power Foldaway Mirrors” next.
Resetting the Power Foldaway Mirrors
You will need to reset the power foldaway mirrors if the
following occurs:
The mirrors are accidentally obstructed while
folding.
They are accidentally manually folded/unfolded.
The mirrors will not stay in the unfolded position.
The mirrors shake and utter at normal driving
speeds.
To reset the power foldaway mirrors, fold and unfold
them three times using the mirror controls. This will reset
them to their normal position.
Outside Automatic Dimming Mirror
If the vehicle has this feature, the driver outside
mirror adjusts for the glare of the headlamps behind
you. SeeAutomatic Dimming Rearview Mirror on
page 2-47for more information.
Park Tilt Mirrors
The vehicle’s outside mirrors can also perform a park tilt
function. This causes the passenger and/or driver’s mirror
to tilt to a preselected position when the vehicle is in
R (Reverse). This feature may be useful in viewing the
curb when parallel parking.
When the vehicle is shifted out of R (Reverse) and a
short delay has occurred, the passenger and/or driver’s
mirror will return to its original position.
To change the preselected tilt position, adjust the
mirrors to the desired position while the vehicle is
in R (Reverse). When the vehicle is shifted out of
R (Reverse), this new position is saved in memory
as the tilt position.
This feature can be enabled/disabled through the Driver
Information Center. SeeDIC Vehicle Customization
on page 3-64for more information.
2-48

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 the right. Check the inside mirror
or glance over your shoulder before changing
lanes.The passenger side mirror is convex shaped. A convex
mirror’s surface is curved so more can be seen from
the driver seat.
Outside Heated Mirrors
The vehicle may have outside heated mirrors which
help clear them of condensation, snow, and ice.
When the rear window defogger button is pressed, the
heated mirrors are also turned on. See “Rear Window
Defogger” underDual Automatic Climate Control System
on page 3-22for more information.

Object Detection Systems
Rear Vision Camera (RVC)
This vehicle may have a Rear Vision Camera system.
Read this entire section before using it.
{CAUTION:

eld of view, below the bumper, or
underneath the vehicle.

vision camera screen, or use the screen during
longer, higher speed backing maneuvers or where
there could be cross-traffic. Your judged distances
using the screen will differ from actual distances.
So if you do not use proper care before backing
up, you could hit a vehicle, child, pedestrian,
bicyclist, or pet, resulting in vehicle damage,
injury, or death. Even though the vehicle has
the RVC system, always check carefully before
backing up by checking behind and around the
vehicle.
Vehicles Without Navigation System

driver when backing up by displaying a view of the area
behind the vehicle. When the key is in the ON/RUN
position and the driver shifts the vehicle into R (Reverse),
the video image automatically appears on the inside rear
view mirror. Once the driver shifts out of R (Reverse),
the video image automatically disappears from the inside
rear view mirror.

it requires from other vehicle systems.
If any other problem occurs or if a problem persists, see
your dealer/retailer.
Rear Vision Camera Location
The image is provided by the camera located on the
rear bumper.
The camera uses a special lens. The distance of the
image that appears on the screen differs from the actual
distance. The area displayed by the camera is limited.
The camera does not display objects which are close
to either corner of the bumper or under the bumper.
The spare tire and carrier extends rearward of the rear
bumper. The area displayed on the screen can vary
according to vehicle orientation or road conditions.
The following illustration shows the eld of view that the
camera provides.
2-52

Notice:The spare tire extends farther away from
rear of the vehicle than the trailer hitch shown on rear
vision camera display. The spare tire could hit an
object even though there appears to be enough
distance on the display between the trailer hitch
and objects behind you causing vehicle or property
damage. Do not use this system to judge the distance
between the spare tire and objects behind you.
When the System Does Not Seem To
Work Properly
The rear vision camera system might not work properly
or display a clear image if:
The RVC is turned off. See “Turning the Rear
Camera System On or Off” earlier in this section.
It is dark.
The sun or the beam of headlights is shining
directly into the camera lens.
Ice, snow, mud, or anything else builds up on the
camera lens. Clean the lens, rinse it with water,
and wipe it with a soft cloth.
The back of the vehicle is in an accident, the
position and mounting angle of the camera
can change or the camera can be affected.
Be sure to have the camera and its position and
mounting angle checked at your dealer/retailer.
There are extreme temperature changes.
2-53

The rear vision camera system display in the rearview
mirror may turn off or not appear as expected due to a
loss of video signal, or no video signal present during
the reverse cycle. The display will be blank and the left
indicator light will slowly ash as long as the vehicle is
in R (Reverse) or until the condition returns to normal.
Pressing and holding
zwhen the left indicator light
is ashing will turn off the video display along with the
left indicator light.
