Rear Vision
Camera (RVC)
If equipped, RVC displays a view of
the area behind the vehicle on the
center stack display when the
vehicle is shifted into R (Reverse) to
aid with parking and low-speed
backing maneuvers.
See Assistance Systems for Parking
or Backing on page 9-49.
Rear Cross Traffic Alert
(RCTA) System
If equipped, the RCTA system uses
a triangle with an arrow displayed
on the RVC screen to warn of traffic
behind your vehicle that may cross
your vehicle's path while in
R (Reverse). In addition, beeps will
sound, or the driver seat will pulse.
See Assistance Systems for Parking
or Backing on page 9-49.
Parking Assist
If equipped, Rear Parking
Assist (RPA) 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). RPA may
display a warning triangle on the
Rear Vision Camera screen and a
graphic on the instrument cluster to
provide the object distance. In

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 10-49.

Be careful not to reset the oil life
display accidentally at any time
other than after the oil is
changed. It cannot be reset
accurately until the next oil
change.
