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

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
Foldaway Mirrors” next.
Resetting the Power Foldaway Mirrors
You will need to reset the power foldaway mirrors if the
following occurs:
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 at least three times using the mirror controls.
This will reset them to their normal position.

Sunroof
The vehicle may be equipped with a power sliding
sunroof. To open or close your sunroof, the ignition
must be on or Retained Accessory Power (RAP) must
be active. SeeRetained Accessory Power (RAP) on
page 2-23for more information.
The sunroof control is
located on the overhead
console. Press the rear
of the control to open the
sunroof to the vent position,
then press the rear of
the control again to
express-open the sunroof.
To close the sunroof, press and hold the front of the
control. The control must be held until the glass stops
moving, so that the sunroof will be fully seated.The sunroof also has a roller sunscreen that can be used
to block the rays of the sun. The roller sunscreen can be
manually operated with the sunroof in an open or closed
position. To open the sunscreen, press up to unlatch it
and roll it back. To close, pull it forward and latch it to the
close position.
If the battery has been recharged, disconnected, or not
working, the sunroof may need to be reprogrammed. To
do this, start the vehicle and press forward on the sunroof
control until it moves to a fully closed position. This resets
the sunroof memory, enabling the sunroof to function
properly.

Windshield Washer
LQ(Washer Fluid):There is a paddle marked
with the windshield washer symbol at the top of the
multifunction lever. To spray washer uid on the
windshield, push the paddle. The wipers will clear the
window and then either stop or return to your preset
speed.
{CAUTION:
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer uid can form ice on the windshield,
blocking your vision.
Cruise Control
9(Off):This position
turns the system off.
If your vehicle is equipped with an Allison
®automatic
transmission, see “Grade Braking and Cruise Grade
Braking (Allison Transmission
®) underTow/Haul Mode
on page 2-31for an explanation of how cruise control
interacts with the tap up/down gear selection, tow/haul
and grade braking systems.
R(On):This position activates the system.
+ (Resume/Accelerate):Push the lever to this symbol
to make the vehicle accelerate or resume to a previously
set speed.
T(Set):Press this button to set the speed.
3-10

Resuming a Set Speed
Suppose you set your cruise control at a desired
speed and then you apply the brake. This, of course,
disengages the cruise control. But you don’t need to
reset it.
Once you’re going about 25 mph (40 km/h) or more,
you can move the cruise control switch briey from on
to resume/accelerate.
You’ll go right back up to your chosen speed and stay
there.
If you hold the switch at resume/accelerate the vehicle
will keep going faster until you release the switch or apply
the brake. So unless you want to go faster, don’t hold the
switch at resume/accelerate.
Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed:
Use the accelerator pedal to get to the higher speed.
Press the set button at the end of the lever, then
release the button and the accelerator pedal. You’ll
now cruise at the higher speed. If the accelerator
pedal is held longer than 60 seconds, cruise control
will turn off.
Move the cruise switch from on to resume/
accelerate. Hold it there until you get up to the speed
you want, and then release the switch. To increase
your speed in very small amounts, move the switch
briey to resume/accelerate. Each time you do this,
your vehicle will go about 1 mph (1.6 km/h) faster.
