POWER SUNROOF — IF EQUIPPED
The power sunroof switch is located between the sun
visors on the overhead console.WARNING!

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.
•In 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.
•Do 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.

ROOF LUGGAGE RACK — IF EQUIPPED
External racks do not increase the total load carrying
capacity of the vehicle. Be sure that the total occupant
and luggage load inside the vehicle, plus the load on the
luggage rack, do not exceed the rated vehicle capacity.
This vehicle is not equipped with roof rack cross rails as
built, unless ordered as optional equipment. Cross rails
must be installed prior to carrying loads on the roof rack.
If not equipped, your authorized dealer can order and
install Moparcross rails built specifically for this roof
rack system or a number of after market rails that are
tailored to your life-style or activities.NOTE:The optional cross rails have seven specific
locations identified by a feature on both the side rail and
the cross rail. Cross rails must be secured in one of the
seven detent locations on the side rail to prevent move-
ment with a sudden stop. For improved windnoise
performance when cross rails are not in use, place them
in detent positions #2 (second detent from the front of the
vehicle) and #7 (detent closest to the rear of the vehicle)
as indicated with a unique feature on the side rails.

CAUTION!
•To 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.
•To 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.
•Long loads which extend over the windshield, such as
wood panels or surfboards, should be secured to both
the front and rear of the vehicle.
•Travel 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
personal injury or property damage. Follow the roof
rack “Cautions” when carrying cargo on your roof
rack.

WARNING!
It is dangerous to shift the selector lever out of P
(Park) or N (Neutral) if the engine speed is higher
than idle speed. If your foot is not firmly on the
brake pedal, the vehicle could accelerate quickly
forward or in reverse. You could lose control of the
vehicle and hit someone or something. Only shift
into gear when the engine is idling normally and
when your foot is firmly on the brake pedal.
Brake Transmission Shift Interlock System
This vehicle is equipped with a brake transmission shift
interlock system (BTSI) that holds the gearshift lever in
the P (Park) position when the ignition switch is in the
LOCK position. To move the gear selector lever out of the
P (Park) position, the ignition switch must be turned to
the ON position, and the brake pedal must be depressed.
Gear Ranges
P (Park)
Supplements the parking brake by locking the transmis-
sion. The engine can be started in this range. Never use P
(Park) while the vehicle is in motion. Apply the parking
brake when leaving the vehicle in this range.
WARNING!
Unintended movement of a vehicle could injure those
in and near the vehicle. As with all vehicles, you
should never exit a vehicle while the engine is running.
Before exiting a vehicle, you should apply the park
brake, shift the transmission into P (Park), and remove
the key from the ignition. Once the key is removed
from the ignition the transmission shift lever is locked
in the P (Park) position, securing the vehicle against
unwanted movement. Furthermore, you should never
leave children unattended inside a vehicle.
