includes information on the radio,
audio players, and navigation
system.
The navigation system provides
detailed maps of most major
freeways and roads. After a
destination has been set, the
system provides turn-by-turn
instructions for reaching the
destination. In addition, the system
can help locate a variety of points of
interest (POIs), such as banks,
airports, restaurants, and more.
See the navigation system manual
for more information.
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.
SeeUltrasonic Parking Assist on
page 9‑34 for more information.
