Rear Vision
Camera (RVC)
If equipped, the RVC displays a
view of the area behind the vehicle
when the vehicle is shifted into
R (Reverse). The display will appear
on either the inside rearview mirror
or navigation screen, if equipped.
To clean the camera lens, located
above the license plate, rinse it with
water and wipe it with a soft cloth.
SeeRear Vision Camera (RVC) on
page 9-36.
Parking Assist
If equipped, this system uses
sensors on the rear bumper to
assist with parking and avoiding
objects while in R (Reverse).
It operates at speeds less than
8 km/h (5 mph). Rear Parking Assist
(RPA) uses audible beeps to
provide distance and system
information. Keep the sensors on the vehicle's
rear bumper clean to ensure proper
operation.
See
Parking Assist on page 9-35.
Power Outlets
The accessory power outlets can be
used to plug in electrical equipment,
such as a cell phone or an MP3
player.
The vehicle may have two
accessory power outlets on the
instrument panel.
Remove the cover to access and
replace when not in use.
SeePower Outlets on page 5-7.
Performance and
Maintenance
Traction Control/
Electronic Stability
Control
The vehicle may have a traction
control system that limits wheel spin
and the StabiliTrak system that
assists with directional control of the
vehicle in difficult driving conditions.
Both systems turn on automatically
every time the vehicle is started.

Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The low tire pressure warning light
alerts to a significant loss in
pressure of one of the vehicle's
tires. If the warning light comes on,
stop as soon as possible and inflate
the tires to the recommended
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits on page 9-9.
The warning light will remain on until
the tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that the
tire pressures are getting low and
the tires need to be inflated to the
proper pressure. The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
See
Tire Pressure Monitor System
on page 10-51.Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and displays a DIC message when
it is necessary to change the engine
oil and filter. The oil life system
should be reset to 100% only
following an oil change.
Resetting the Oil Life System
1. Turn the ignition to ON/RUN, with the engine off.
2. Fully press and release the accelerator pedal three times
within five seconds.
3. Turn the key to LOCK/OFF.
See Engine Oil Life System on
page 10-8.

This light comes on briefly when the
engine is started. If the light does not come on, have
the vehicle serviced by your dealer.
If the system is working normally,
the indicator light turns off.
If the light is on and not flashing, the
TCS and potentially the StabiliTrak
system have been disabled. A DIC
message may display. Check the
DIC messages to determine which
feature(s) is no longer functioning
and whether the vehicle requires
service.
If the indicator/warning light is on
and flashing, the TCS and/or the
StabiliTrak system is actively
working.
See
Traction Control/Electronic
Stability Control on page 9-29.

SERVICE TRACTION
CONTROL
If the vehicle has StabiliTrak, this
message displays when there is a
problem with the Traction Control
System (TCS). When this message
displays, the system will not limit
wheel spin. Adjust your driving
accordingly. See your dealer for
service. SeeTraction Control/
Electronic Stability Control on
page 9-29.
STABILITRAK INITIALIZING
If the vehicle has StabiliTrak, this
message may display until first
driving the vehicle and exceeding
40 km/h (25 mph) for two minutes.
The StabiliTrak system is not
functional until this message has
turned off. See Traction Control/
Electronic Stability Control on
page 9-29.
TRACTION XX
STABILITRAK XX
If the vehicle has StabiliTrak, this
message displays when the traction
control and/or StabiliTrak systems
have been turned on or off. Adjust
your driving accordingly. To limit
wheel spin and realize the full
benefits of the stability
enhancement system, you should
normally leave StabiliTrak on.
However, you should turn
StabiliTrak off if the vehicle gets
stuck in sand, mud, ice, or snow
and you want to rock the vehicle to
attempt to free it, or if you are
driving in extreme off-road
conditions and require more wheel
spin. See If the Vehicle Is Stuck on
page 9-8. To turn the StabiliTrak
system on or off, see Traction
Control/Electronic Stability Control
on page 9-29. STABILITRAK OFF may also
display when the stability control
has been automatically disabled.
There are several conditions that
can cause this message to appear.
.One condition is overheating,
which could occur if StabiliTrak
activates continuously for an
extended period of time.
.The message also displays if the
brake system warning light is on.
See
Brake System Warning
Light on page 5-19.
.The message could display if the
stability system takes longer
than usual to complete its
diagnostic checks due to driving
conditions.
.The message displays if an
engine or vehicle related
problem has been detected and
the vehicle needs service. See
your dealer.
