WARNING!
²Never leave children in a vehicle, with the keys in
the ignition switch. Occupants, particularly unat-
tended children, can become entrapped by the
power sunroof while operating the power sunroof
switch. Such entrapment may result in serious
injury or death.
²In an accident, there is a greater risk of being
thrown from a vehicle with an open sunroof. You
could also be seriously injured or killed. Always
fasten your seat belt properly and make sure all
passengers are properly secured too.
²Do not allow small children to operate the sun-
roof. Never allow fingers or other body parts, or
any object to project through the sunroof opening.
Injury may result.
Opening Sunroof - Express
Press the switch rearward and release, and the sunroof
will open automatically from any position. The sunroof
will open fully, then stop automatically. This is called
Express Open. During Express Open operation, any
movement of the sunroof switch will stop the sunroof.
Closing Sunroof - Express
Press the switch forward and release, and the sunroof
will close automatically from any position. The sunroof
will close fully and stop automatically. This is called
Express Close. During Express Close operation, any
movement of the switch will stop the sunroof.

If not equipped, your authorized dealer can order and
install Mopartcross rails built specifically for this roof
rack system or a number of after market rails that are
tailored to your life-style or activities.
The optional cross rails have five specific locations iden-
tified by a feature on both the side rail and the cross rail.
Cross rails must be secured in one of the five detent
locations on the side rail to prevent movement with a
sudden stop. The cross rails must also be installed using
the correct orientation (the longer rail toward the front)
with the wind trip toward the front of the vehicle as
shown below. For improved windnoise performance
when cross rails are not in use, place them in detent
positions #1 (first detent from the front of the vehicle) and
#4 (second detent from the rear of the vehicle) as indi-
cated with a unique feature on the side rails.The grab
handles (A) on the back of the vehicle (if equipped) are
not to be used as a towing feature.NOTE:If the rear cross rail (or any metallic object) is
placed over the satellite radio antenna (if equipped), you
may experience interruption of satellite radio reception.
For improved satellite radio reception, place the rear
cross rail in detent position #4 when not in use.

CAUTION!
²To prevent damage to the roof of your vehicle, DO NOT
carry any loads on the roof rack without cross rails
installed. The load should be secured and placed on top
of the cross rails, not directly on the roof. If it is
necessary to place the load on the roof, place a blanket or
some other protection between the load and the roof
surface.
²To avoid damage to the roof rack and vehicle, do not
exceed the rated load capacity of your cross rail system
or the roof rack system maximum load capacity of 150
lbs (68 kg). Always distribute heavy loads as evenly as
possible and secure the load appropriately.
²Long loads which extend over the windshield, such as
wood panels or surfboards, should be secured to both
the front and rear of the vehicle.
²Travel at reduced speeds and turn corners carefully
when carrying large or heavy loads on the roof rack.
Wind forces, due to natural causes or nearby truck
traffic, can add sudden upward loads. This is especially
true on large flat loads and may result in damage to the
cargo or your vehicle.
WARNING!
Cargo must be securely tied before driving your
vehicle. Improperly secured loads can fly off the
vehicle, particularly at high speeds, resulting in per-
sonal injury or property damage. Follow the roof rack
ªCautionsº when carrying cargo on your roof rack.

8. Tachometer
The red segments indicate the maximum permissible
engine revolutions-per-minute (r.p.m. x 1000) for each
gear range. Before reaching the red area, ease up on the
accelerator.
9. Security Alarm System Indicator Light Ð If
Equipped
This light will flash rapidly for approximately 15 seconds
when the vehicle theft alarm is arming. The light will
flash at a slower speed continuously after the alarm is set.
The security light will also come on for about three
seconds when the ignition is first turned on.
10. Oil Pressure Warning Light
This light shows low engine oil pressure. The light
should turn on momentarily when the engine is
started. If the light turns on while driving, stop the
vehicle, and shut off the engine as soon as possible. A
continuous chime will sound when this light turns on.Do not operate the vehicle until the cause is corrected.
This light does not show how much oil is in the engine.
The engine oil level must be checked under the hood.
11. Electronic Stability Program (ESP) Indicator
Light/Traction Control System (TCS) Indicator Light
This indicator light starts to flash as soon as the
tires lose traction and the ESP system becomes
active. The ªESP/TCS Indicator Lightº also
flashes when TCS is active. If the ªESP/TCS
Indicator Lightº begins to flash during acceleration, ease
up on the accelerator and apply as little throttle as
possible. Be sure to adapt your speed and driving to the
prevailing road conditions. The ªESP/TCS Indicator
Lightº will flash any time the ESP or TCS is active and
helping to improve vehicle stability. If the ªESP/TCS
Indicator Lightº is on solid, the ESP system has been
turned off by the driver or a temporary condition exists
that will not allow full ESP function.

or rear axles has been exceeded but the total load is
within the specified GVWR. If so, weight must be shifted
from front to rear or rear to front as appropriate until the
specified weight limitations are met. Store the heavier
items down low and be sure that the weight is distributed
equally. Stow all loose items securely before driving.
Improper weight distributions can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.
CAUTION!
Do not load your vehicle any heavier than the GVWR
or the maximum front and rear GAWR. If you do,
parts on your vehicle can break, or it can change the
way your vehicle handles. This could cause you to
lose control. Also overloading can shorten the life of
your vehicle.
TRAILER TOWING
In this section you will find safety tips and information
on limits to the type of towing you can reasonably do
with your vehicle. Before towing a trailer carefully re-
view this information to tow your load as efficiently and
safely as possible.
To maintain warranty coverage, follow the requirements
and recommendations in this manual concerning ve-
hicles used for trailer towing.
Common Towing Definitions
The following trailer towing related definitions will assist
you in understanding the following information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and tongue
weight. The total load must be limited so that you do not
exceed the GVWR.

WARNING!
Improper towing can lead to an injury accident.
Follow these guidelines to make your trailer towing
as safe as possible:
Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have an accident.
²When hauling cargo or towing a trailer, do not over-
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to brakes,
axle, engine, transmission, steering, suspension, chas-
sis structure or tires.
²Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
hook retainers of the vehicle hitch. Cross the chains
under the trailer tongue and allow enough slack for
turning corners.
²Vehicles with trailers should not be parked on a grade.
When parking, apply the parking brake on the tow
vehicle. Put the tow vehicle transmission in P (Park).
For four-wheel-drive vehicles, make sure the transfer
case is not in N (Neutral). Always, block or9chock9the
trailer wheels.
²GCWR must not be exceeded.
²Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
