A crash can damage the
airbag systems in the vehicle.
A damaged airbag system
may not work properly and may
not protect you and your
passenger(s) in a crash, resulting
in serious injury or even death. To
help make sure the airbag
systems are working properly
after a crash, have them
inspected and any necessary
replacements made as soon as
possible.If an airbag inflates or the vehicle
has been in a crash, the sensing
system may shut down the high
voltage system. When this occurs,
the high voltage battery is
disconnected and the vehicle will
not start. The SERVICE VEHICLE
SOON message in the Driver
Information Center (DIC) will be
displayed. Before the vehicle can be
operated again, it must be serviced
at your dealer.
If an airbag inflates, you will need to
replace airbag system parts. See
your dealer for service.
If the airbag readiness light stays on
after the vehicle is started or comes
on when you are driving, the airbag
system may not work properly. Have
the vehicle serviced right away. See
Airbag Readiness Light on
page 5‑17
for more information.

Power Outlets
The accessory power outlets can be
used to plug in electrical equipment,
such as a cell phone or MP3 player.
There are three accessory power
outlets:
.Inside the front of the floor
console.
.On the rear of the floor console.
.Inside the instrument panel
storage area.
The power outlets supply power
while the vehicle is on, or if the
vehicle is in Retained Accessory
Power (RAP). See Retained
Accessory Power (RAP) on
page 9‑21. Remove the cover to access and
replace when not in use.
Certain accessory plugs may not be
compatible with the accessory
power outlet and could overload
vehicle or adapter fuses. If a
problem is experienced, see your
dealer.
When adding electrical equipment,
be sure to follow the installation
instructions included with the
equipment. See
Add-On Electrical
Equipment on page 9‑65.
Notice: Hanging heavy
equipment from the power outlet
can cause damage not covered
by the vehicle warranty. The
power outlets are designed for
accessory power plugs only, such
as cell phone charge cords.
Warning Lights,
Gauges, and
Indicators
Warning lights and gauges can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gauges could
prevent injury.
Warning lights come on when there
could be a problem with a vehicle
function. Some warning lights come
on briefly when the propulsion
system is started to indicate they
are working.
Gauges can indicate when there
could be a problem with a vehicle
function. Often gauges and warning
lights work together to indicate a
problem with the vehicle.

comes on and stays on while
driving, or when one of the gauges
shows there may be a problem,
check the section that explains what
to do. Waiting to do repairs can be
costly and even dangerous.

passenger safety belt is buckled,
the corresponding safety belt
symbol in the instrument cluster
turns green. If a safety belt is not
initially buckled, the instrument
cluster displays a gray safety belt
symbol. While the vehicle is moving,
if a second row passenger who was
previously buckled becomes
unbuckled, the corresponding safety
belt symbol will change to flashing
red for several seconds and a chime
may sound.Airbag Readiness Light
This light shows if there is an
electrical problem. The system
check includes the airbag sensor,
passenger sensing system, the
pretensioners, the airbag modules,
the wiring, and the crash sensing
and diagnostic module. For more
information on the airbag system,
seeAirbag System on page 3‑19.
The airbag readiness light comes on
and stays on for several seconds
when the vehicle is started. Then
the light goes out. A message may also display in the
Driver Information Center (DIC).
See
Airbag System Messages on
page 5‑53 for more information.
{WARNING
If the airbag readiness light stays
on after the vehicle is started or
comes on while driving, it means
the airbag system might not be
working properly. The airbags in
the vehicle might not inflate in a
crash, or they could even inflate
without a crash. To help avoid
injury, have the vehicle serviced
right away.

Passenger Airbag Status
Indicator
The vehicle has a passenger
sensing system. SeePassenger
Sensing System on page 3‑26 for
important safety information. The
passenger airbag status indicator is
in the overhead console.
United States
Canada When the vehicle is started, the
passenger airbag status indicator
will light ON and OFF, or the symbol
for on and off for several seconds
as a system check. Then, after
several more seconds, the status
indicator will light either ON or OFF,
or the on or off symbol to let you
know the status of the front
outboard passenger frontal airbag
and knee airbag.
If the word ON or the on symbol is
lit on the passenger airbag status
indicator, it means that the front
outboard passenger frontal airbag
and knee airbag are allowed to
inflate.
If the word OFF or the off symbol is
lit on the airbag status indicator, it
means that the passenger sensing
system has turned off the front
outboard passenger frontal airbag
and knee airbag.
If, after several seconds, both status
indicator lights remain on, or if there
are no lights at all, there may be a
problem with the lights or the
passenger sensing system. See
your dealer for service.
{WARNING
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. See
Airbag Readiness
Light on page 5‑17 for more
information, including important
safety information.

Brake System Warning
Light
The vehicle brake system consists
of two hydraulic circuits. If one
circuit is not working, the remaining
circuit can still work to stop the
vehicle. For normal braking
performance, both circuits need to
be working.
If the warning light comes on, there
is a brake problem. Have the brake
system inspected right away.
MetricEnglish
This light comes on briefly when the
vehicle is turned on. If it does not
come on then, have it fixed so it will
be ready to warn if there is a
problem. If the light comes on and stays on,
there is a base brake problem.
{WARNING
The brake system might not be
working properly if the brake
system warning light is on.
Driving with the brake system
warning light on can lead to a
crash. If the light is still on after
the vehicle has been pulled off
the road and carefully stopped,
have the vehicle towed for
service.
Electric Parking Brake
Light
This status light comes on when the
parking brake is applied. If the light
flashes and stays on after the
parking brake is released, or while
driving, there is a problem with the
electric parking brake system.
If the light does not come on,
or remains flashing, see your dealer.

Service Electric Parking
Brake Light
The Service Electric Parking Brake
light should come on briefly when
the vehicle is in ON/RUN. If it does
not come on, have it fixed so it will
be ready to warn if there is a
problem.
If this light stays on, there is a
problem with a system on the
vehicle that is causing the parking
brake system to work at a reduced
level. The vehicle can still be driven,
but should be taken to a dealer as
soon as possible. SeeElectric
Parking Brake on page 9‑34 for
more information. If a message
displays in the Driver Information Center (DIC), see
Brake System
Messages on page 5‑48 for more
information.
Antilock Brake System
(ABS) Warning Light
This light should come on briefly
when the vehicle is in ON/RUN. If it
does not come on, have the vehicle
serviced by your dealer.
If the ABS warning light stays on
longer than a few seconds after the
vehicle is in ON/RUN, or comes on
and stays on while driving, try
resetting the system. To reset the
system:
1. While driving, pull over when it is safe to do so.
2. Place the vehicle in P (Park). 3. Turn the vehicle off.
4. Restart the vehicle.
If the ABS warning light remains on
after resetting the system or comes
on again while driving, the vehicle
needs service. If the ABS warning
light is on, but the regular brake
system warning light is not on, the
antilock brakes are not working
properly, but the regular brakes are
still functioning. Have the vehicle
serviced right away. If both brake
lights are on, the vehicle does not
have antilock brakes, and there is a
problem with the regular brakes as
well. Have the vehicle towed for
service. See
Towing the Vehicle on
page 10‑81.
