148 Driving and Operating
An obstacle detection is indicated by beeps.
The time between beeps gets shorter as the
vehicle approaches the obstacle. Repeated
beeps are heard when the distance is less
than 30 cm (12 in).
To be detected, objects must be at least
25 cm (10 in) off the ground and below rear
door level. Objects must also be within 2.5 m
(8 ft) from the rear bumper. This distance
may be less during warmer or humid
weather.
Turning the System On and Off
The system can be disabled through the
Driver Information Center (DIC). See“Park
Assist” underDriver Information Center (DIC)
0 82.
RPA defaults to the on setting each time the
vehicle is started.
Turn RPA off when towing a trailer.
When the System Does Not Seem to
Work Properly
The following messages may be displayed
on the DIC:
SERVICE PARK ASSIST : If this message
occurs, take the vehicle to your dealer for
repair. PARK ASSIST OFF :
This message occurs if
the driver disables the system or if the
vehicle is driven above 8 km/h (5 mph) in
R (Reverse).
PARK ASST BLOCKED SEE OWNERS
MANUAL : This message can occur under the
following conditions:
.The sensors are not clean. Keep the rear
bumper free of mud, dirt, snow, ice, slush,
and frost. The message may not clear
until frost or ice has melted all around
and inside the sensor.
.A trailer is attached to the vehicle, or a
bicycle or an object hanging out of the
rear door during the current or last drive
cycle. RPA will return to normal operation
after it is determined the object is
removed. This could take a few drive
cycles.
.A tow bar is attached to the vehicle.
Other conditions may affect system
performance, such as vibrations from a
jackhammer or the compression of air
brakes on a very large truck.
Forward Collision Alert (FCA)
System
If equipped, the FCA system may help to
avoid or reduce the harm caused by
front-end crashes. When approaching a
vehicle ahead too quickly, FCA provides a
red flashing alert on the windshield and
rapidly beeps. FCA also lights an amber
visual alert if following another vehicle
much too closely.
FCA detects vehicles within a distance of
approximately 60 m (197 ft) and operates at
speeds above 40 km/h (25 mph).
{Warning
FCA is a warning system and does not
apply the brakes. When approaching a
slower-moving or stopped vehicle ahead
too rapidly, or when following a vehicle
too closely, FCA may not provide a
warning with enough time to help avoid
a crash. It also may not provide any
warning at all. FCA does not warn of
pedestrians, animals, signs, guardrails,
bridges, construction barrels, or other (Continued)
