SECOND (2):This position gives you more power but
lower fuel economy. You can use SECOND (2) on
hills. It can help control your speed as you go down
steep mountain roads, but then you would also want to
use your brakes off and on.
If you manually select SECOND (2), the transmission
will drive in second gear. You may use this feature
for reducing the speed of the rear wheels when you are
trying to start your vehicle from a stop on slippery
road surfaces. Once the vehicle is moving, shift into
DRIVE (D).
FIRST (1):This position gives you even more power,
but lower fuel economy than SECOND (2). You can use
it on very steep hills, or in deep snow or mud. If the
shift lever is put in FIRST (1) while the vehicle is moving
forward, the vehicle will not shift into rst gear until
the vehicle is going slowly enough.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transmission. If you are
stuck, do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
On cold days, approximately 32°F (0°C) or colder, your
transmission is designed to shift differently until the
engine reaches normal operating temperature. This is
intended to improve heater performance.Tow/Haul Mode
Your vehicle is equipped
with a tow/haul mode.
The button for this feature
is located on the end of
the column shift lever.
You can use this feature to assist when towing or
hauling a heavy load. See “Tow/Haul Mode” under
Towing a Trailer on page 4-50for more information.
The tow/haul mode also interacts with the Road Sensing
Suspension (RSS) feature to enhance the ride when
trailering or with a loaded vehicle. SeeRoad Sensing
Suspension on page 4-9.

Sunroof
Your vehicle may be equipped with a power sliding
sunroof. To open or close your sunroof, the ignition

closed, press the forward side of the button to open the
sunroof to the vent position.The sunroof is also equipped with a sunshade which
you can pull forward to block sun rays.
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 upward and the button is held for
an additional twenty seconds. This will reset the memory
and enable the sunroof to function properly.

If the ignition or radio is turned off with the CD in the
player, it will stay in the player. When the ignition
or radio is turned on, the CD will start playing where it
stopped, if it was the last selected audio source.
When a CD is inserted, the CD symbol will appear on

The CD player can play the smaller 3 inch (8 cm)
single CDs with an adapter ring. Full-size CDs and the
smaller CDs are loaded in the same manner.
If playing a CD-R, the sound quality may be reduced

of the music that has been recorded, and the way the
CD-R has been handled. There may be an increase
in skipping, difficulty in nding tracks, and/or difficulty in
loading and ejecting. If these problems occur, check
the bottom surface of the CD. If the surface of the CD is
damaged, such as cracked, broken, or scratched, the
CD will not play properly. If the surface of the CD
is soiled, seeCare of Your CDs and DVDs on
page 3-101for more information.
If there is no apparent damage, try a known good CD.
Do not add any label to a CD, it could get caught in the
CD player. If a CD is recorded on a personal computer
and a description label is needed, try labeling the top of
the recorded CD with a marking pen instead.Notice:If you add any label to a CD, insert more
than one CD into the slot at a time, or attempt
to play scratched or damaged CDs, you could
damage the CD player. When using the CD player,
use only CDs in good condition without any
