Retained Accessory Power (RAP)
Your vehicle is equipped with Retained Accessory
Power (RAP) which will allow certain features of your
vehicle to continue working for up to 20 minutes after the
ignition key is turned to LOCK.
Your radio, front wipers, sunroof, if equipped, and power
windows will work when the ignition key is in ON or
ACC. Once the key is turned from ON to LOCK, these
features will continue to work for up to 20 minutes
or until a door is opened.
Starting the Engine
Automatic Transmission
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position — that 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 gear selector should be in NEUTRAL 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 Your Engine
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
your engine gets warm.
Notice:Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor. Wait about
15 seconds between each try to help avoid draining
your battery or damaging your starter.
2. If the engine does not start within 10 seconds, push
the accelerator pedal all the way to the oor, while
you hold the ignition key in START. When the
engine starts, let go of the key and let up on the
accelerator pedal. Wait about 15 seconds between
each try.

Front Armrest Storage Area
Your vehicle is equipped with a front armrest storage
area. To open, lift the latch on the front of the armrest
and pull up.
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 4-52.
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.
2-43

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.
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. SeeCargo Tie
Downs on page 2-45for more information.
Rear Storage Area
Your vehicle is equipped with 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 be equipped with 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 is equipped with 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.

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. SeeRetained Accessory
Power (RAP) on page 2-16.
The switch used to operate
the sunroof is located in
the headliner.
Open/Close:Press 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 the back of the switch to vent the sunroof.
To stop the sunroof before it reaches its full vent
position, press the front or back of the switch again and
release it when the desired position is reached.
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.

Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day. DRL
can be helpful in many different driving conditions, but
they can be especially helpful in the short periods after
dawn and before sunset. Fully functional daytime running
lamps are required on all vehicles rst sold in Canada.
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, only the DRLs will be on. The
other lamps will not be 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 3-14.
Vehicles rst sold in Canada cannot turn off DRL
unless certain conditions are met. SeeExterior Lamps
on page 3-14.
Automatic Headlamp System
When it is dark enough outside, your automatic
headlamp system will turn on your headlamps at the
normal brightness along with other lamps such as
the taillamps, sidemarker, parking lamps, roof marker
lamps and the instrument panel lights. 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 your 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 sees a
change in lighting lasting longer than the delay.
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 approximately one minute for
the automatic headlamp system to change to DRL if it is
light outside. During that delay, your instrument panel
cluster may not be as bright as usual. Make sure your
instrument panel brightness control is in the full bright
position. SeeInstrument Panel Brightness on page 3-18.

Off-Road Lamps
The off-road lamps, if equipped, provide auxiliary
lighting when your 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 climate controls.
One switch is used for the front lower-grille mounted
off-road lamps, if equipped, and the other switch is used
for the roof-mounted off-road lamps, if equipped.
To use the lamps, remove the covers from the lamps
and press the switch to turn them on. Press the switch
again to turn them 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 will remain on even after the ignition
is turned off. The off-road lamp switch must be
pressed to turn them off.

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 (if available). 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 tunnels may cause loss of
XM signal for a period of time. The radio may display
NO SIGNAL to indicate interference.
Care of Your CDs
Handle CDs carefully. Store them in their original cases
or other protective cases and away from direct
sunlight and dust. If the surface of a CD is soiled,
dampen a clean, soft cloth in a mild, neutral detergent
solution and clean it, wiping from the center to the edge.
Be sure never to touch the side without writing when
handling CDs. Pick up CDs by grasping the outer edges
or the edge of the hole and the outer edge.
Care of the CD Player
The use of CD lens cleaners for CD players is not
advised, due to the risk of contaminating the lens of the
CD optics with lubricants internal to the CD mechanism.
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.
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
that the XM™ satellite antenna is not obstructed.

Loading Your Vehicle for Off-Road
Driving
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.
{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.
CAUTION: (Continued)
CAUTION: (Continued)

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.
You will nd other important information in this manual.
