Section 2 Features and Controls
2-1
Power Windows
The controls for the power windows are located on the
armrest on each of the side doors. The switches
operate the windows when the ignition is in RUN,
ACCESSORY or when Retained Accessory Power
(RAP) is active. See “Retained Accessory Power” under
Ignition Positions on page 2-31.
The driver’s door also has a switch for each of the
passenger’s windows.
Press the top of the switch to lower the window. Pull up
the top of the switch to raise the window.
Express-Down Windows
The driver’s and front passenger’s window switches have
an express-down feature that allows you to lower the
window without continuously pressing the switch. Press
the top of the window switch down fully to activate the
feature. Lightly press the switch to open the window
slightly. The express-down feature can be interrupted at
any time by pulling up on the top of the switch.
Lockout Switch
Press the lockout switch to prevent passengers from
operating the power windows from their switches. A light
in the lockout switch will come on to show that the
switch has been activated. Press the lockout switch
again to return to normal operation.
Sun Visors
To block out glare, you can swing down the visors. You
can also swing them out to help block glare at the
front and side windows.
Illuminated Visor Vanity Mirrors
Pull the sunvisor down and lift the mirror cover to turn
on the lamps.
2-26
Outside Camper-Type Mirrors
If your vehicle is equipped with outside camper-type
mirrors, they can be adjusted so you can have a clear
view of objects behind you.
To extend the manual camper mirrors, pull out the
mirror head to extend it for better visibility. Adjust the
mirror glass manually to the desired position.
To extend the power camper mirrors, move the selector
switch, located above the mirror control, to the middle
position. The mirror control will illuminate. Press the left
or right side of the mirror control to slide the mirror heads
away or toward the body of the vehicle. Adjust the mirror
glass by using the power mirror switches. SeeOutside
Power Mirrors on page 2-56.
Outside Power Mirrors
The controls are located on
the driver’s door armrest.
Move the upper selector switch to the left or right to
choose the mirror you want to adjust; then press the dots
located on the four-way control pad to adjust the mirror.
The mirrors may also include a memory function which
works in conjunction with the memory seats. See
Memory Seat on page 2-90for more information.
2-56
Power Folding Mirrors
To fold or unfold the mirrors, move the selector switch,
located above the mirror control, to the middle position.
The mirror control will illuminate. Press the right or left
side of the mirror control to fold or unfold the mirrors. You
may notice the mirror glass adjust as the mirrors fold in;
this is normal. The mirror glass will reposition itself once
the mirrors are unfolded.
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 Folding Mirrors” next.
Resetting the Power Folding Mirrors
You will need to reset the power folding mirrors if:
They are accidently 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 folding mirrors, fold and unfold them
at least three times using the mirror controls. This will
reset them to their normal detent position.
Outside Convex Mirror
Your passenger’s side mirror is convex. 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.
2-57
If a hand, arm, or other object is blocking the sunroof
glass panel as it is closing, the glass panel will stop
at the obstruction. After the obstruction is removed, the
glass panel can be closed or opened.
Use care not to leave the sunroof open for long periods
of time as debris may collect in the tracks.
If the battery has been recharged, disconnected or is
not working, you may need to reprogram the sunroof. To
do this, start the vehicle and press the forward side of
the sunroof button until the glass panel moves to a fully
closed position. Release, and press again to move to
the vent position which occurs when the sunroof is fully
tilted rearward. This will reset the memory and enable
the sunroof to function properly.Vehicle Personalization
Memory Seat
If your vehicle has this
feature, then 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 seat, throttle and brake
pedals, both the driver’s and passenger’s outside mirror,
the radio station presets and the last chosen climate
control system settings. 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 the numbers
on the back of the remote keyless entry transmitters.
2-90
To store the memory settings, do the following:
1. Adjust the driver’s seat (including the seatback
recliner, lumbar, and side wing area), throttle
and brake pedals, both of the outside mirrors, and
the radio station presets to your preference.
2. Press and hold the 1 or 2 (for driver 1 or 2) button
of the memory control for three seconds. A double
chime will sound to let you know that the position
has been stored.
To repeat the procedure for a second driver, follow the
preceding steps, but press the other numbered
memory control button.
Each time button 1 or 2 is pressed and released while
the vehicle is in PARK (P), a single chime will sound and
the memory position will be recalled.If you use the unlock button on the remote keyless entry
transmitter to enter your vehicle, the preset driver’s
seat, throttle and brake pedal, mirror positions, radio
station presets and the last choosen climate control
settings will be recalled if programmed to do so through
the Driver Information Center (DIC). SeeDIC Operation
and Displays on page 3-54. The numbers on the
back of the transmitters, 1 or 2, correspond to the
numbers on the memory controls.
The seat, throttle and brake pedals and mirror positions
can also be recalled when placing the key in the
ignition if programmed to do so through the Driver
Information Center (DIC). SeeDIC Operation and
Displays on page 3-54.
To stop recall movement of the memory seat feature at
any time, press one of the memory buttons or power
seat controls.
