Object Detection
Systems
Ultrasonic Parking Assist
For vehicles with the Ultrasonic
Rear Parking Assist (URPA) system,
it operates at speeds less than
8 km/h (5 mph), and assists the
driver with parking and avoiding
objects while in R (Reverse). The
sensors on the rear bumper are
used to detect the distance to an
object up to 2.5 m (8 ft) behind the
vehicle, and at least 25.4 cm (10 in)
off the ground.
{WARNING
The Ultrasonic Rear Parking
Assist (URPA) system does not
replace driver vision. It cannot
detect:
.Objects that are below the
bumper, underneath the
vehicle, or too close or far
from the vehicle
.Children, pedestrians,
bicyclists, or pets.
If you do not use proper care
before and while backing, vehicle
damage, injury, or death could
occur. Even with URPA, always
check behind the vehicle before
backing up. While backing, be
sure to look for objects and check
the vehicle's mirrors.
How the System Works
URPA comes on automatically when
the shift lever is moved into
R (Reverse). A single tone sounds
to indicate the system is working.
URPA operates only at speeds less
than 5 mph (8 km/h).
An obstacle is indicated by audible
beeps. The interval between the
beeps becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm (12 in) the beeps are
continuous.
To be detected, objects must be at
least 25.4 cm (10 in) off the ground
and below liftgate 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.

Side Blind Zone
Alert (SBZA)
The vehicle may have a Side Blind
Zone Alert (SBZA) system. Read
this entire section before using the
system.
{WARNING
SBZA is only a lane changing aid
and does not replace driver
vision. SBZA does not detect:
.Vehicles outside the side
blind zones which may be
rapidly approaching.
.Pedestrians, bicyclists,
or animals.(Continued)
WARNING (Continued)
Failure to use proper care when
changing lanes may result in
damage to the vehicle, injury,
or death. Always check the
outside and rearview mirrors,
glance over your shoulder, and
use the turn signal before
changing lanes.
When the system detects a vehicle
in the side blind zone, amber SBZA
displays light up in the side mirrors.
This indicates that it may be unsafe
to change lanes. Before making a
lane change, always check the
SBZA display, check the outside
and rearview mirrors, look over your
shoulder for vehicles and hazards,
and use the turn signal.
SBZA Detection Zones
The SBZA sensor covers a zone of
approximately one lane over from
both sides of the vehicle, 3.5 m
(11 ft). This zone starts at each side
mirror and goes back approximately
5.0 m (16 ft). The height of the zone
is approximately between
0.5 m (1.5 ft) and 2.0 m (6 ft)
off the ground.
Use caution while changing lanes
when towing a trailer, as the SBZA
detection zones do not change
when a trailer is towed.

How the System Works
Left Side MirrorDisplayRight Side Mirror Display
When the vehicle is started, both
outside mirror displays will briefly
come on to indicate that the system
is operating. When the vehicle is
moving forward, the left or right side
mirror SBZA display will light up if a
vehicle is detected in that blind
zone. If the turn signal is activated
and a vehicle is also detected on
the same side, the SBZA display will
flash to give you extra warning not
to change lanes.
SBZA displays do not come on
while the vehicle is approaching or
passing other vehicles. At speeds
greater then 32 km/h (20 mph),
SBZA displays may come on when a vehicle you have passed remains
in or drops back into the
detection zone.
SBZA can be disabled through the
Driver Information Center (DIC). See
Driver Information Center (DIC) on
page 5‑29
for more information.
If the SBZA is disabled by the
driver, the SBZA mirror displays will
not light up during normal driving.
When the System Does Not Seem
To Work Properly
Occasional missed alerts can occur
under normal circumstances and will
increase in wet conditions. The
system does not need to be
serviced due to an occasional
missed alert. The number of missed
alerts will increase with increased
rainfall or road spray.
If the SBZA displays do not light up
when the system is on and vehicles
are in the blind zone, the system
may need service. Take the vehicle
to your dealer. SBZA is designed to ignore
stationary objects; however, the
system may occasionally light up
due to guard rails, signs, trees,
shrubs, and other stationary objects.
This is normal system operation, the
vehicle does not need service.
SBZA does not operate when the
left or right corners of the rear
bumper are covered with mud, dirt,
snow, ice, slush, or in heavy
rainstorms. For cleaning
instructions, see
“Washing the
Vehicle” underExterior Care on
page 10‑98. If the DIC still displays
the SIDE BLIND ZONE SYS.
UNAVAILABLE message after
cleaning the bumper, see your
dealer.
The SBZA displays may remain on
if a trailer is attached to the vehicle,
or a bicycle or object is extending
out to either side of the vehicle.

Rear Vision
Camera (RVC)
This vehicle may have a Rear
Vision Camera system. Read this
entire section before using it.
{WARNING
The Rear Vision Camera (RVC)
system does not replace driver
vision. RVC does not:
.Detect objects that are
outside the camera's field of
view, below the bumper,
or underneath the vehicle.
.Detect children, pedestrians,
bicyclists, or pets.
Do not back the vehicle by only
looking at the RVC screen, or use
the screen during longer, higher
speed backing maneuvers or
where there could be cross-traffic. (Continued)
WARNING (Continued)
Your judged distances using the
screen will differ from actual
distances.
If you do not use proper care
before backing up, you could hit a
vehicle, child, pedestrian,
bicyclist, or pet, resulting in
vehicle damage, injury, or death.
Even though the vehicle has the
RVC system, always check
carefully before backing up by
checking behind and around the
vehicle.
Vehicles Without Navigation
System
The rear vision camera system is
designed to help the driver when
backing up by displaying a view of
the area behind the vehicle. When
the key is in the ON/RUN position
and the driver shifts the vehicle into
R (Reverse), the video image
automatically appears on the inside
rear view mirror. Once the driver
shifts out of R (Reverse), the video
image automatically disappears
from the inside rear view mirror.
Turning the Rear Vision Camera
System Off or On
To turn off the rear vision camera
system, press and hold
z, located
on the inside rearview mirror, until
the left indicator light turns off. The
rear camera vision display is now
disabled.

Notice:This vehicle was not
designed for fuel that contains
methanol. Do not use fuel
containing methanol. It can
corrode metal parts in the fuel
system and also damage plastic
and rubber parts. That damage
would not be covered under the
vehicle warranty.
Filling the Tank
{WARNING
Fuel vapor burns violently and a
fuel fire can cause bad injuries.
To help avoid injuries to you and
others, read and follow all the
instructions on the fuel pump
island. Turn off the engine when
refueling. Do not smoke near fuel
or when refueling the vehicle. Do
(Continued)
WARNING (Continued)
not use cellular phones. Keep
sparks, flames, and smoking
materials away from fuel. Do not
leave the fuel pump unattended
when refueling the vehicle. This is
against the law in some places.
Do not re-enter the vehicle while
pumping fuel. Keep children away
from the fuel pump; never let
children pump fuel.
The tethered fuel cap is located
behind a hinged fuel door on the
driver side of the vehicle. If the
vehicle has E85 fuel capability, the
fuel cap will be yellow and state that
E85 or gasoline can be used. See
Fuel E85 (85% Ethanol) on
page 9‑74.

9-76 Driving and Operating
To open the fuel door, push the
rearward center edge in and release
and it will open.
To remove the fuel cap, turn it
slowly counterclockwise. The fuel
cap has a spring in it; if the cap is
released too soon, it will spring back
to the right.
While refueling, hang the tethered
fuel cap from the hook on the
fuel door.
{WARNING
Fuel can spray out on you if you
open the fuel cap too quickly.
If you spill fuel and then
something ignites it, you could be
badly burned. This spray can
happen if the tank is nearly full,
and is more likely in hot weather.
Open the fuel cap slowly and wait
for any hiss noise to stop. Then
unscrew the cap all the way.
Be careful not to spill fuel. Do not
top off or overfill the tank and wait a
few seconds after you have finished
pumping before removing the
nozzle. Clean fuel from painted
surfaces as soon as possible. See
Exterior Care on page 10‑98. When replacing the fuel cap, insert
the tether in its hole before
tightening the cap. Turn the fuel cap
clockwise until it clicks. It will require
more effort to turn the fuel cap on
the last turn as you tighten it. Make
sure the cap is fully installed. The
diagnostic system can determine if
the fuel cap has been left off or
improperly installed. This would
allow fuel to evaporate into the
atmosphere. See
Malfunction
Indicator Lamp on page 5‑22.
If the vehicle has a Driver
Information Center (DIC), the
TIGHTEN GAS CAP message
displays if the fuel cap is not
properly installed.

{WARNING
If a fire starts while you are
refueling, do not remove the
nozzle. Shut off the flow of fuel by
shutting off the pump or by
notifying the station attendant.
Leave the area immediately.
Notice: If a new fuel cap is
needed, be sure to get the right
type of cap from your dealer. The
wrong type fuel cap might not fit
properly, might cause the
malfunction indicator lamp to
light, and could damage the fuel
tank and emissions system. See
Malfunction Indicator Lamp on
page 5‑22.
Filling a Portable Fuel
Container
{WARNING
Never fill a portable fuel container
while it is in the vehicle. Static
electricity discharge from the
container can ignite the fuel
vapor. You can be badly burned
and the vehicle damaged if this
occurs. To help avoid injury to you
and others:
.Dispense fuel only into
approved containers.
.Do not fill a container while it
is inside a vehicle, in a
vehicle's trunk, pickup bed,
or on any surface other than
the ground.
(Continued)
WARNING (Continued)
.Bring the fill nozzle in contact
with the inside of the fill
opening before operating the
nozzle. Contact should be
maintained until the filling is
complete.
.Do not smoke while
pumping fuel.
.Do not use a cellular phone
while pumping fuel.

Important considerations that have
to do with weight:
.The weight of the trailer
.The weight of the trailer tongue
.The weight on the vehicle's tires
.And the weight of the trailering
combination
Driving with a Trailer
{WARNING
When towing a trailer, exhaust
gases may collect at the rear of
the vehicle and enter if the
liftgate, trunk/hatch, or rear-most
window is open.
Engine exhaust contains Carbon
Monoxide (CO) which cannot be
seen or smelled. It can cause
unconsciousness and even death.(Continued)
WARNING (Continued)
To maximize safety when towing
a trailer:
.Have the exhaust system
inspected for leaks and make
necessary repairs before
starting a trip.
.Never drive with the liftgate,
trunk/hatch, or rear-most
window open.
.Fully open the air outlets on
or under the instrument
panel.
.Adjust the Climate Control
system to a setting that
brings in only outside air and
set the fan speed to the
highest setting. See Climate
Control System in the Index.
For more information about
Carbon Monoxide, see Engine
Exhaust on page 9‑37. Towing a trailer requires a certain
amount of experience. The
combination you are driving is
longer and not as responsive as the
vehicle itself. Get acquainted with
the handling and braking of the rig
before setting out for the open road.
Before starting, check all trailer hitch
parts and attachments, safety
chains, electrical connectors, lamps,
tires and mirrors. If the trailer has
electric brakes, start the
combination moving and then apply
the trailer brake controller by hand
to be sure the brakes work.
During the trip, check occasionally
to be sure that the load is secure
and the lamps and any trailer
brakes still work.
