Side Blind Zone
Alert (SBZA)
If available, this feature will alert you
to vehicles located in the vehicle's
side blind zone. When the system
detects a vehicle in the side blind
zone, the SBZA display will light up
in the corresponding outside side
mirror.
The system is enabled at every
vehicle startup. It can be disabled
through the Driver Information
Center (DIC).
If the message SIDE BLIND ZONE
SYSTEM UNAVAILABLE appears
on the DIC, the system has been
disabled because the sensor is
blocked and cannot detect vehicles
in the blind zone. The sensor may
be blocked by mud, dirt, snow, ice,
slush, or even heavy rainstorms.
This message may also activate
during heavy rain or due to road
spray. The vehicle does not need
service.See
Side Blind Zone Alert (SBZA)
on page 9‑54 for more information.Rear Vision
Camera (RVC)
If available, the RVC displays a view
of the area behind the vehicle when

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 9‑57.
Ultrasonic Parking Assist
If available, Ultrasonic Rear Parking
Assist (URPA) 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). URPA uses audible beeps to
provide distance and system
information.
Keep the sensors on the vehicle's
rear bumper clean to ensure proper
operation.
See
Ultrasonic Parking Assist on
page 9‑53 for more information.
Power Outlets
The accessory power outlets can be

accessory power outlet in the rear
cargo area on the passenger side.
The accessory power outlets are
powered, even with the ignition off.
Continuing to use accessory power
outlets while the ignition is in LOCK/

Remote Vehicle Start
If available, this feature allows you
to start the engine from outside of
the vehicle. It may also start up the
vehicle's heating or air conditioning
systems and rear window defogger.
Normal operation of the system will
return after the key is turned to the
ON/RUN position.
If the vehicle has an automatic
climate control system, the climate
control system will default to a
heating or cooling mode depending
on the outside temperatures. If the
vehicle does not have an automatic
climate control system, the system
will turn on at the setting the vehicle
was set to when the vehicle was
last turned off. During a remote start, if the vehicle
has an automatic climate control
system and heated seats, the
heated seats will turn on during
colder outside temperatures and will
shut off when the key is turned to
ON/RUN. If the vehicle does not
have an automatic climate control
system, during remote start,
manually turn the heated seats on
and off. See
Heated and Ventilated
Front Seats on page 3‑9 for
additional information.
Laws in some communities may
restrict the use of remote starters.
For example, some laws may
require a person using the remote
start to have the vehicle in view
when doing so. Check local
regulations for any requirements
on remote starting of vehicles.
Do not use the remote start feature
if the vehicle is low on fuel. The
vehicle may run out of fuel.
