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 in-
stalled. 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 protec-
tion 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.

engine revolutions-per-minute (r.p.m. x 1000) for each
gear range. Before reaching the red area, ease up on the
accelerator.

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 “ESP/TCS Indicator Light” also
flashes when TCS is active. If the “ESP/TCS
Indicator Light” 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 “ESP/TCS Indicator
Light” will flash any time the ESP or TCS is active and
helping to improve vehicle stability. If the “ESP/TCS
Indicator Light” 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.
