Section 2 Features and Controls
86

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)
Your vehicle has Retained Accessory Power (RAP)
which allows certain features of your vehicle to
continue working for up to 20 minutes after
the ignition key is turned to LOCK.
The radio, front wipers, power windows, and a
sunroof if your vehicle has one, will work when the
ignition key is in ON or ACC. Once the key is turned
from ON to LOCK, these features continue working
for up to 20 minutes or until a door is opened.
Starting the Engine
Place the transmission in the proper gear.
Automatic Transmission
Move your shift lever to PARK (P) or
NEUTRAL (N). Your engine will not start in
any other position -- this is a safety feature.
To restart when you are already moving, use
NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could
damage the transmission. Shift to PARK (P)
only when your vehicle is stopped.
Manual Transmission
The shift lever should be in the NEUTRAL position
and the parking brake engaged. Hold the clutch
pedal to the oor and start the engine. Your
vehicle will not start if the clutch pedal is not all
the way down. That is a safety feature.
Starting Procedure
1. With your foot off the accelerator pedal, turn
the ignition key to START. When the engine
starts, let go of the key. The idle speed will go
down as the engine gets warm. Do not race the
engine immediately after starting it. Operate
the engine and transmission gently to allow the
oil to warm up and lubricate all moving parts.

Luggage Carrier
If your vehicle has this feature, you can load cargo
on your vehicle.
The luggage carrier consists of siderails attached
to the roof. The crossrails attach into the
siderails and can be moved back and forth to
accommodate various cargo sizes.
Notice:Loading cargo on the luggage carrier
that weighs more than 250 lbs. (113 kg) or
hangs over the rear or sides of the vehicle may
damage your vehicle. Load cargo only on
top of the crossrails and tie the cargo down to
the crossrail support cargo tie-down loops,
making sure to fasten it securely
Do not exceed the maximum vehicle capacity
when loading your vehicle. For more information
on vehicle capacity and loading, seeLoading Your
Vehicle on page 289.
Adjusting the Crossrails
Adjust the crossrails to t your load by doing the
following:
1. Use the provided crossrail key to unlock the
crossrail end cap by turning it
counterclockwise.
144

Stop Tabs
If your vehicle has a sunroof, it will have a
crossrail stop tab placed in the siderail. This tab
prevents you from moving the crossrails past
the opening of the sunroof and loading cargo too
far forward.
Your vehicle may have cargo tie downs. Once you
load the cargo onto the crossrails, secure it by
tying it down to the cargo tie downs. Do not load
cargo directly on the roof of your vehicle. See
Cargo Tie Downs on page 146for more
information.
Rear Storage Area
Your vehicle has a rear storage area located on
the passenger’s side of the cargo area. To
open, pull the two tabs out and open lid.
Convenience Net
Your vehicle may have a convenience net in the
rear of the vehicle. Put small loads behind the net.
The net is not for heavier loads. Store them as
far forward as you can.
Cargo Cover
Notice:If you put items onto the cargo cover,
the weight of the items could cause the
attachment clips to break. You would no longer
be able to attach and use the cargo cover.
The repairs would not be covered by your
warranty. Never put anything on top of
the cargo cover.
If your vehicle has a cargo cover, you can use it
to cover items in the rear of the vehicle. Remove
the cover from its pouch and place the loops
found on each corner of the cover, over the
two pegs in each corner of the rear if the vehicle.
When it is not in use, fold up the cover and
return it to the pouch.
Cargo Tie Downs
Your vehicle may have four cargo tie-downs.
These tie-downs are located in tracks on the roof
of the vehicle. Each tie-down can be moved to
anywhere on the track. To loosen, turn the
tie-down counterclockwise until it moves freely in
the track. To tighten, turn the tie-down clockwise.
146

Sunroof
Your vehicle may have a power sliding sunroof.
The ignition must be on or in ACC, or Retained
Accessory Power (RAP) must be active. See
Retained Accessory Power (RAP) on page 103.
The switch used to
operate the sunroof is
located in the headliner.
Open/Close:Press and release the back of the
switch to open the sunroof. If the sunshade is in the
closed position, it will automatically open with the
sunroof. To stop the sunroof before it has reached
the full open position press and release the front or
back of the switch. An air deector will raise when
the sunroof is fully opened.
Press the front of the switch to close the sunroof.To stop the sunroof before it is fully closed, press
and release the front or back of the switch.
Vent:Press and hold the back of the switch to
vent the sunroof. To stop the sunroof before
it reaches its full vent position, release the switch.
Do not keep the sunroof open for long periods
of time as debris may collect in the tracks.
Sunshade Operation
The sunshade will open automatically open with
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.
Anti-Pinch Feature
If an object is in the path of the sunroof when it is
closing, the anti-pinch feature will detect the
object and stop the sunroof from closing at the
point of the obstruction. The sunroof will then
return to the full-open or vent position, and the air
deector will raise.
147

The DRL system will come on when the following
conditions are met:
The ignition is on.
The exterior lamps control is in AUTO.
The transmission is not in PARK (P) if
you have an automatic transmission.
The light sensor determines it is daytime.
When the DRL are on, no other lamps are on.
The instrument panel will not be lit up either.
For vehicles rst sold in Canada, if parking
lamps are manually turned on, DRL will stay on.
When it begins to get dark, the automatic
headlamp system will switch from DRL to the
headlamps.
As with any vehicle, you should turn on the
regular headlamp system when you need it.
To turn off the DRL, seeExterior Lamps
on page 162.
Vehicles rst sold in Canada cannot turn
off DRL unless certain conditions are met.
SeeExterior Lamps on page 162.
Automatic Headlamp System
When it is dark enough outside, the automatic
headlamp system will turn on after the transmission
has been shifted from PARK (P) to DRIVE (D).
The headlamps, taillamps, sidemarker, parking
lamps, roof marker lamps, and the instrument panel
lights will turn on at normal brightness. The radio
lights will become more dim when the headlights
are off compared to when the headlights are on.
Your vehicle has a light sensor located on the top of
the instrument panel. Be sure it is not covered, or
the system will be on whenever the ignition is on.
The system may also turn on the headlamps when
driving through a parking garage, heavy overcast
weather, or a tunnel. This is normal.
There is a delay in the transition between the
daytime and nighttime operation of the Daytime
Running Lamps (DRL) and the automatic headlamp
system so that driving under bridges or bright
overhead street lights does not affect the system.
The DRL and automatic headlamp system will only
be affected when the light sensor detects a change
in lighting lasting longer than the delay.
165

If you start your vehicle in a dark garage, the
automatic headlamp system will come on
immediately. Once you leave the garage, it will
take about one minute for the automatic headlamp
system to change to DRL if it is light outside.
During that delay, the instrument panel cluster
may not be as bright as usual. Make sure
the instrument panel brightness control is in
the full bright position. SeeInstrument Panel
Brightness on page 167.
Off-Road Lamps
The off-road lamps, if the vehicle has them,
provide auxiliary lighting when the vehicle is
used off road. These lamps are not intended to
be used in place of existing vehicle lighting.
The lamps are not to be used on any public street
or highway and are to be covered when not in
use. Check your state and local laws before
installing or using any auxiliary lighting. In some
states it may be necessary to remove the roof
lamps when operating the vehicle on the highway.The switches for the off-road lamps are located in
the center of the instrument panel below the climate
controls. One switch is used for the front lower-grille
mounted off-road lamps, if the vehicle has them,
and the other switch is used for the roof-mounted
off-road lamps, if the vehicle has them.
To use the lamps, remove the covers from the
lamps and press the switch to turn them on or
off. An indicator light on the switch will turn
on when the lamps are on.
Notice:Turning on the off-road lamps before
removing the lamp covers could damage the
off-road lamps and the covers. Always remove
the covers before turning on the off-road lamps.
The off-road lamps remain on even after the ignition
is turned off. The off-road lamp switch must be
pressed to turn them off.

Care of the CD Player
Do not use CD lens cleaners for CD players
because the lens of the CD optics can become
contaminated by lubricants.
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 to the fender. If tightening is
required, tighten by hand, then with a wrench
one quarter turn.
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.

Loading Your Vehicle for Off-Road
Driving
{CAUTION:
Cargo on the load oor piled higher
than the seatbacks can be thrown
forward during a sudden stop. You
or your passengers could be injured.
Keep cargo below the top of the
seatbacks.
Unsecured cargo on the load oor can
be tossed about when driving over
rough terrain. You or your passengers
can be struck by ying objects.
Secure the cargo properly.
Heavy loads on the roof raise the
vehicle’s center of gravity, making it
more likely to roll over. You can be
seriously or fatally injured if the
vehicle rolls over. Put heavy loads
inside the cargo area, not on the roof.
Keep cargo in the cargo area as far
forward and low as possible.There are some important things to remember
about how to load your vehicle.
The heaviest things should be on the
load oor and forward of your rear axle.
Put heavier items in the rear area, as far
forward as you can.
Be sure the load is secured properly, so
driving on the off-road terrain does not
toss things around.
You will nd other important information in this
manual. SeeLoading Your Vehicle on page 289
andTires on page 367.
