WARNING!
• Never leave children unattended in avehicle, or with access to an unlocked
vehicle. Never leave the key fob in or
near the vehicle, or in a location acces-
sible to children. Do not leave the igni-
tion of a vehicle equipped with Keyless
Enter-N-Go in the ACC or ON/RUN
mode. Occupants, particularly unat-
tended children, can become entrapped
by the power sunroof while operating the

• Rear of the center console storagecompartment.
When the vehicle is turned off, be sure to
unplug any equipment as to not drain the
battery of the vehicle. All accessories con-
nected to the outlet(s) should be removed or
turned off when the vehicle is not in use to
protect the battery against discharge.WARNING!
To avoid serious injury or death:
• Only devices designed for use in this type of outlet should be inserted into any
12 Volt outlet.
• Do not touch with wet hands.
• Close the lid when not in use and while
driving the vehicle.
• If this outlet is mishandled, it may cause
an electric shock and failure.
CAUTION!
•Many accessories that can be plugged in
draw power from the vehicle's battery, even
when not in use (i.e., cellular phones,
etc.). Eventually, if plugged in long
enough, the vehicle's battery will discharge
sufficiently to degrade battery life and/or
prevent the engine from starting.
• Accessories that draw higher power (i.e.,coolers, vacuum cleaners, lights, etc.),
will discharge the battery even more
quickly. Only use these intermittently
and with greater caution.
CAUTION!
• After the use of high power draw acces-sories, or long periods of the vehicle not
being started (with accessories still
plugged in), the vehicle must be driven a
sufficient length of time to allow the
generator to recharge the vehicle's bat-
tery.
Power Inverter — If Equipped
A 115 or 230 Volt (150 Watts Maximum)
outlet is located on the center stack of the
instrument panel, to the right of the radio.
This outlet can power cellular phones, elec-
tronics and other low power devices requiring
power up to 150 Watts. Certain high-end
video game consoles will exceed this power
limit, as will most power tools.

bin, insert the key into the keyhole on the
push button and turn clockwise to lock or
counterclockwise to unlock. Always return
the key to the upright (vertical) position be-
fore removing the key from the push button.
CAUTION!
• Ensure cargo bin lids are closed and latched before moving or driving vehicle.
• Loads applied to the top of the bin lid
should be minimized to prevent damage
to the lid and latching/hinging mecha-
nisms.
• Damage to the RamBox bin may occur
due to heavy/sharp objects placed in bin
that shift due to vehicle motion. In order
to minimize potential for damage, se-
CAUTION!
cure all cargo to prevent movement and
protect inside surfaces of bin from
heavy/sharp objects with appropriate
padding.

WARNING LIGHTS AND MESSAGES
Red Warning Lights
— Seat Belt Reminder Warning Light
This light indicates when the driver or pas-
senger seat belt is unbuckled. When the
ignition is first placed in the ON/RUN or
ACC/ON/RUN position and if the driver’s seat
belt is unbuckled, a chime will sound and the
light will turn on. When driving, if the driver
or front passenger seat belt remains unbuck-
led, the Seat Belt Reminder Light will flash or
remain on continuously and a chime will
sound. Refer to “Occupant Restraints Sys-
tems” in “Safety” for further information.
— Air Bag Warning Light
This light indicates a fault with the air bag,
and will turn on for four to eight seconds as a
bulb check when the ignition is placed in the
ON/RUN or ACC/ON/RUN position. This light
will illuminate with a single chime when a
fault with the air bag has been detected, it
will stay on until the fault is cleared. If thelight is either not on during startup, stays on,
or turns on while driving, have the system
inspected at an authorized dealer as soon as
possible.
— Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on it may
indicate that the parking brake is applied,
that the brake fluid level is low, or that there
is a problem with the anti-lock brake system
reservoir.
If the light remains on when the parking brake
has been disengaged, and the fluid level is at
the full mark on the master cylinder reservoir, it
indicates a possible brake hydraulic system
malfunction or that a problem with the Brake
Booster has been detected by the Anti-Lock
Brake System (ABS) / Electronic Stability Con-
trol (ESC) system. In this case, the light will
remain on until the condition has been cor-
rected. If the problem is related to the brake
booster, the ABS pump will run when applying
the brake, and a brake pedal pulsation may be
felt during each stop.
The dual brake system provides a reserve
braking capacity in the event of a failure to a
portion of the hydraulic system. A leak in
either half of the dual brake system is indi-
cated by the Brake Warning Light, which will
turn on when the brake fluid level in the
master cylinder has dropped below a speci-
fied level.
The light will remain on until the cause is
corrected.
NOTE:
The light may flash momentarily during sharp
cornering maneuvers, which change fluid level
conditions. The vehicle should have service
performed, and the brake fluid level checked.
If brake failure is indicated, immediate repair
is necessary.
WARNING!
Driving a vehicle with the red brake light
on is dangerous. Part of the brake system
may have failed. It will take longer to stop
the vehicle. You could have a collision.
Have the vehicle checked immediately.

hicle is running, immediate service is re-
quired and you may experience reduced per-
formance, an elevated/rough idle, or engine
stall and your vehicle may require towing.
The light will come on when the ignition is
placed in the ON/RUN or ACC/ON/RUN posi-
tion and remain on briefly as a bulb check. If
the light does not come on during starting,
have the system checked by an authorized
dealer.— Electric Power Steering Fault
