Mirrors
Manual Rearview Mirror
Pull the tab under the mirror toward you to reduce the
glare from headlamps behind you after dark. Push
the tab away from you for normal daytime operation.
Automatic Dimming Rearview Mirror
If your vehicle has this feature, the mirror automatically
changes to reduce glare from headlamps behind
you. A photocell on the back of the mirror senses when
it is becoming dark outside. Another photocell built
into the mirror surface senses when headlamps
are behind you.
At night, when the glare is too high, the mirror will
gradually darken to reduce glare. This change may take
a few seconds. The mirror will return to its clear
daytime state when the vehicle is put into REVERSE (R)
or when the glare is reduced.AUTO (Automatic Dimming):This button is located at
the base of the mirror. Use it to turn on the automatic
feature. The button has an indicator light to show it is on.
OFF:Press this button to turn the automatic feature off.
Time Delay
The automatic mirror has a time delay feature which
prevents unnecessary switching from the night back to
the day position. This delay prevents rapid changing
of the mirror as you drive under lights and through traffic.
Cleaning the Photocells
Use a cotton swab and glass cleaner to clean the
photocells and mirror face when necessary.
Cleaning the Mirror
When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner. Do not spray
glass cleaner directly on the mirror as that may cause
the liquid cleaner to enter the mirror housing.

Outside Manual Mirror
Adjust your outside mirrors so you can see a little of the
side of your vehicle and the area beside and behind
your vehicle from a comfortable driving position.
You can also fold the mirrors in before entering a car
wash. Pull the mirrors in toward the vehicle. Push
the mirrors back out when ®nished.
Outside Power Mirrors
If your vehicle has this
feature, the controls are
located on the driver's door
armrest.Move the selector switch to the left or right to choose
the driver's or passenger's mirror, then use the
arrows located on the four-way control pad to move the
mirror in the direction you want the mirror to go.
Put the selector switch back in the center position when
®nished adjusting the mirror so that you don't
accidentally bump into the control pad and get the
mirror out of adjustment.
Outside Convex Mirror
A convex mirror's surface is curved so you can see
more 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.
2-40

Outside Heated Mirrors
Your vehicle may be equipped with heated outside
rearview mirrors.
The heated mirror button is
located to the lower right
of the mode knob on
the climate control system.
The button has an
indicator light to indicate if
the heated mirror feature
is on or off.
When the heated mirror feature is turned on, the
defogger will warm the mirrors to help clear them of
snow or condensation. The heated mirror feature
will turn off automatically when the mirror is clear.

glove box and lower the door. The glove box should

Exit Lighting
With exit lighting, the interior lamps will come on when
you remove the key from the ignition to help you
see while exiting the vehicle. These lights will stay on
for a short period of time and then will go out, if the
DOME OVERRIDE button is in the out position.
Front Map Lamps
If your vehicle is a Crew Cabžand has front map
lamps, they are located in the overhead console. For all
other vehicles that have this feature, they are located
on the inside rearview mirror. The front map lights
that are located on the inside rearview mirror will
automatically come on for approximately 40 seconds
when the doors are unlocked with the remote keyless
entry transmitter (if equipped) or until the ignition key is
turned to RUN or ACCESSORY. The lamps will also
stay on for approximately 40 seconds after you exit the
vehicle, unless you lock the doors with the remote
keyless entry transmitter.
You can also turn the lamps on and off by pressing the
switch near each lamp.
Dome Lamp

below the exterior lamps control, to set the dome lamps
to come on automatically when any door is opened,
or to remain off. To turn the lamps off, press the button
in. With the button in, the dome lamps will remain off
when any door is opened. To return the lamps to
automatic operation, press the button again and return it

·Check your mirrors, glance over your shoulder, and
start your left lane change signal before moving out
of the right lane to pass. When you are far
enough ahead of the passed vehicle to see its front
in your inside mirror, activate your right lane
change signal and move back into the right lane.
(Remember that your right outside mirror is convex.
The vehicle you just passed may seem to be
farther away from you than it really is.)
·Try not to pass more than one vehicle at a time on
two-lane roads. Reconsider before passing the
next vehicle.
·Don't overtake a slowly moving vehicle too rapidly.
Even though the brake lamps are not ¯ashing, it
may be slowing down or starting to turn.
·If you're being passed, make it easy for the
following driver to get ahead of you. Perhaps you
can ease a little to the right.
Loss of Control
Let's review what driving experts say about what
happens when the three control systems (brakes,
steering and acceleration) don't have enough friction
where the tires meet the road to do what the driver has
asked.
In any emergency, don't give up. Keep trying to steer
and constantly seek an escape route or area of
less danger.
Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not
ªoverdrivingº those conditions. But skids are always
possible.
The three types of skids correspond to your vehicle's
three control systems. In the braking skid, your wheels
aren't rolling. In the steering or cornering skid, too much
speed or steering in a curve causes tires to slip and lose
cornering force. And in the acceleration skid, too much
throttle causes the driving wheels to spin.
A cornering skid is best handled by easing your foot off
the accelerator pedal.
