if equipped.
Side Blind Zone
Alert (SBZA)
If equipped, SBZA will detect
moving vehicles in the next lane
over in the vehicle's side blind zone
area. When this happens, the SBZA
display will light up in the
corresponding outside side mirror
and will flash if the turn signal is on.
See Side Blind Zone Alert (SBZA)
0 195.
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).
To clean the camera lens, rinse it
with water and wipe it with a soft
cloth.
See Rear Vision Camera (RVC)
0 193.
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) and 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 0194.

Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
. Pass with caution.
. Keep windshield wiping
equipment in good shape.
. Keep the windshield washer fluid
reservoir filled.
. Have good tires with proper
tread depth. See Tires0255.
. Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips include:
.Keep the vehicle serviced and in
good shape.
. Check all fluid levels and brakes,
tires, cooling system, and
transmission.
. Shift to a lower gear when going
down steep or long hills.
{Warning
Using the brakes to slow the
vehicle on a long downhill slope
can cause brake overheating, can
reduce brake performance, and
could result in a loss of braking.
Shift the transmission to a lower
gear to let the engine assist the
brakes on a steep downhill slope.
{Warning
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. This can cause
overheating of the brakes and
loss of steering assist. Always
have the engine running and the
vehicle in gear.
. Drive at speeds that keep the
vehicle in its own lane. Do not
swing wide or cross the
center line. .
Be alert on top of hills;
something could be in your lane
(e.g., stalled car, accident).
. Pay attention to special road
signs (e.g., falling rocks area,
winding roads, long grades,
passing or no-passing zones)
and take appropriate action.
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires and
the road creates less traction or
grip, so drive carefully. Wet ice can
occur at about 0 °C (32 °F) when
freezing rain begins to fall. Avoid
driving on wet ice or in freezing rain
until roads can be treated.
For slippery road driving:
.Accelerate gently. Accelerating
too quickly causes the wheels to
spin and makes the surface
under the tires slick.
. Turn on Traction Control. See
Traction Control/Electronic
Stability Control 0188.

How the System Works
RPA comes on automatically when
the shift lever is moved into
R (Reverse). A single beep sounds
to indicate the system is working.
RPA operates only at speeds less
than 8 km/h (5 mph).
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) 0111.
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.
Side Blind Zone
Alert (SBZA)
If equipped, the SBZA system is a
lane-changing aid that assists
drivers with avoiding crashes that
occur with moving vehicles in the
side blind zone (or spot) areas. The
SBZA warning display will light up in
the corresponding outside side
mirror and will flash if the turn signal
is on.
