Safety Belts
This section of the manual
describes how to use safety belts
properly. It also describes some
things not to do with safety belts.
{WARNING
Do not let anyone ride where
a safety belt cannot be worn
properly. In a crash, if you or
your passenger(s) are not
wearing safety belts, the injuries
can be much worse. You can hit
things inside the vehicle harder
or be ejected from the vehicle.
You and your passenger(s) can
be seriously injured or killed.
In the same crash, you might
not be, if you are buckled up.
Always fasten your safety belt,
and check that your passenger(s)
are restrained properly too.
{WARNING
It is extremely dangerous to ride
in a cargo area, inside or outside
of a vehicle. In a collision, people
riding in these areas are more
likely to be seriously injured or
killed. Do not allow people to ride
in any area of your vehicle that
is not equipped with seats and
safety belts. Be sure everyone
in the vehicle is in a seat and
using a safety belt properly.
This vehicle has indicators as a
reminder to buckle the safety belts.
See Safety Belt Reminders on
page 5‑14 for additional information.

9-42 Driving and Operating
Object Detection
Systems
Ultrasonic Parking Assist
For vehicles with the Ultrasonic
Rear Parking Assist (URPA)
system, it assists the driver with
parking and avoiding objects while
in R (Reverse). URPA operates at
speeds less than 8 km/h (5 mph),
and the sensors on the rear bumper
detect objects up to 2.5 m (8 ft)
behind the vehicle, and at least
20 cm (8 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 8 km/h (5 mph).
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 20 cm (8 in) off the ground and
below trunk level. Objects must also
be within 2.5 m (8 ft) from the rear
bumper. The distance objects can
be detected may be less during
warmer or humid weather.

Driving and Operating 9-43
PARK ASSIST OFF displays on
the Driver Information Center (DIC)
to indicate that URPA is off. The
message disappears after a short
period of time.
Turning the System On and Off
The URPA system can be turned on
and off using the park assist button
located next to the shift lever.
The park assist button lights up
when the system is on and turns
off when it has been disabled.
URPA defaults to the on setting
each time the vehicle is started.
When the System Does Not
Seem to Work Properly
SERVICE PARK ASSIST:If this
message occurs, take the vehicle
to your dealer to repair the system.
PARK ASSIST OFF: If the URPA
system does not activate due to a
temporary condition, the message
displays on the DIC. See Driver
Information Center (DIC) on
page 5‑25 for more information.
This can occur under the following
conditions:
.The driver has disabled the
system.
.The ultrasonic sensors are not
clean. Keep the vehicle's rear
bumper free of mud, dirt, snow,
ice, and slush. For cleaning
instructions, see Exterior Care
on page 10‑92.
.An object was hanging out of the
trunk during the last drive cycle.
Once the object is removed,
URPA will return to normal
operation.
.The vehicle's bumper is
damaged. Take the vehicle to
your dealer to repair the system.
.Other conditions may affect
system performance, such as
vibrations from a jackhammer
or the compression of air brakes
on a very large truck.
If the system is still disabled after
driving forward at least 40 km/h
(25 mph), take the vehicle to your
dealer.

9-54 Driving and Operating
While refueling, hang the tethered
fuel cap from the hook on the fuel
door. Reinstall the cap by turning it
clockwise until it clicks
{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.
Do not top off or overfill the tank and
wait a few seconds before removing
the nozzle. Clean fuel from painted
surfaces as soon as possible.
See Exterior Care on page 10‑92.
{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 of 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 5‑17.
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.
