Section 2 Features and Controls
2-2

Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is all the way in.
If it is, turn the steering wheel left and right while
you turn the key hard. If none of this works,
then your vehicle needs service.
B (ACC/ACCESSORY):This position lets things like
the radio and the windshield wipers operate while
the engine is off.
Lengthy operation of features such as the radio in the
ACC/ACCESSORY ignition position and the ON/RUN
position may drain the battery and prevent your vehicle
from starting. Do not operate your vehicle in the
ACC/ACCESSORY ignition position for a long period
of time.
C (ON/RUN):This is the position for driving. It is the
position the ignition switch returns to after the engine
starts, and the key is released.
The battery could be drained if you leave the key in
the ACC/ACCESSORY or ON/RUN position with
the engine off. You may not be able to start your
vehicle if the battery is allowed to drain for an extended
period of time.
D (START):This position starts the engine.Key In the Ignition
Never leave your vehicle with the keys inside, as it is an
easy target for joy riders or thieves. If you leave the
key in the ignition and park your vehicle, a chime
will sound, when you open the driver’s door. Always
remember to remove your key from the ignition and take
it with you. This will lock your ignition and transmission.
Also, always remember to lock the doors.
The battery could be drained if you leave the key in the
ignition while your vehicle is parked. You may not be
able to start your vehicle after it has been parked for an
extended period of time.
Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
10 minutes after the engine is turned off:
Audio System
Sunroof
Power Windows
The sunroof and power windows will continue to work
up to 10 minutes after the key is turned to LOCK/OFF or
until any door is opened. The radio will continue to
work for up to 10 minutes after the key is turned
to LOCK/OFF or until the driver’s door is opened.

Cargo Area Floor Drains
Your vehicle also has four cargo-area oor drains (A)
located under the cargo mat, if it has this feature,
near the sides of the cargo area. These drains should
be cleaned periodically to allow water to exit the
cargo area.The cargo mat has cutouts for the drains. You can ush
the drains through the cutouts, but if the cargo area
is extremely dirty you can lift up the edges of the cargo
oor mat or take the whole mat out and ush the
drains with water. The drain grates can be removed to
clear any debris that has accumulated in the drain.
Sunroof
The vehicle may have a
power sliding sunroof.
The ignition must be on or
in the accessory position,
or Retained Accessory
Power (RAP) must be
active.
SeeRetained Accessory Power (RAP) on page 2-29.
The switch used to operate the sunroof is located in the
overhead console.
2-67

Express-Open/Close Sunroof
The sunroof has a feature which allows the sunroof
panel to be opened or closed without continuously
pressing the switch. The express-open can be stopped
at any time by pushing the front of the switch a
second time.
The sunroof has four positions:
Comfort open stop:To open the sunroof and
sunshade, press the rear of the switch quickly and
release. The glass panel will open to an interim
position that reduces wind noise. For information on
using the sunshade, see “Sunshade Operation” later.
Full open stop:To open the sunroof further, press
the rear of the switch quickly once more.
Express close:To close the sunroof, press the front
of the switch quickly and release.
Vent:The vent position allows the rear of the sunroof
to be opened and tilted upward. With the sunroof in
the fully closed position, press and hold the front of
the switch until the sunroof reaches the desired vent
position or until it stops moving. To close the sunroof
from the vent position, press and hold the rear of the
switch until the sunroof is fully closed.
Do not leave the sunroof open for long periods of time
as debris may collect in the tracks.
Anti-Pinch Protection Feature
If something gets caught between the glass panel and
roof frame while the sunroof is closing, the glass
panel will stop and open half way, and the deector will
raise fully.
If something gets caught between the glass panel and
the roof frame during the tilt down operation, the
glass panel will stop and open fully.
If the sunroof panel receives a strong impact, the
anti-pinch protection feature may work even if nothing
gets caught between the glass panel and roof frame.
Sunshade Operation
The sunshade will open automatically when opening the
sunroof.
However, it can manually be pulled shut after the
sunroof is closed. To adjust the sunshade, push it
backward or pull it forward to the desired position.
The sunshade cannot be adjusted further than
the current closed position of the sunroof.
Notice:If you force the sunshade forward of the
sliding glass panel, damage will occur and the
sunroof may not open or close properly. Always
close the glass panel before closing the sunshade.

XM™ Satellite Radio Service
XM™ Satellite Radio Service gives digital radio
reception from coast-to-coast in the 48 contiguous
United States, and in Canada. Just as with FM, tall
buildings or hills can interfere with satellite radio signals,
causing the sound to fade in and out. In addition,
traveling or standing under heavy foliage, bridges,
garages, or through tunnels could cause loss of the XM
signal for a period of time. The radio may display NO XM
SIGNAL to indicate interference.
Fixed Mast Antenna
The xed mast antenna can withstand most car washes
without being damaged. If the mast should ever become
slightly bent, straighten it out by hand. If the mast is badly
bent, replace it.
Check occasionally to make sure the mast is still
tightened.
XM™ Satellite Radio Antenna
System
The XM™ Satellite Radio antenna is located on the roof
of your vehicle. Keep this antenna clear of snow and
ice build up for clear radio reception.
If your vehicle has a sunroof, the performance of the
XM™ system may be affected if the sunroof is open.
Loading items onto the roof of your vehicle can interfere
with the performance of the XM™ system. Make sure
the XM™ Satellite Radio antenna is not obstructed.
