How the System Works
When the vehicle is shifted into
R (Reverse) the front and rear
sensors are automatically turned on,
after the vehicle is shifted out of
R (Reverse), the rear sensors are
turned off and the front sensors
stay on until the vehicle is above
a certain speed. The front sensors
may also be turned on by pressing
the park assist button located next
to the shift lever without shifting
into R (Reverse) while the vehicle
is traveling at a low speed.
See“Turning the System On
and Off” later in this section.
When the vehicle is in N (Neutral),
the system may be active. If the
vehicle is in a car wash, the sensors
may detect objects in the car wash.
See “Turning the System On and
Off” later in this section to turn the
system off. High-toned beeps heard from the
front speakers are for objects
detected near the front bumper.
Low-toned beeps heard from the
rear speakers are for objects
detected near the rear bumper.
When an object is detected, high or
low‐tone beeps are heard. As the
vehicle gets closer to an object, the
time between the beeps becomes
shorter. When the distance is less
than 30 cm (11.8 in), beeping is
continuous. The distance may
be less during warmer or humid
weather.
PARK ASSIST OFF displays on
the Driver Information Center (DIC)
to indicate that UFRPA is off.
The message disappears after
a short period of time.
Front Display
The front display is located in the
instrument panel in the center of
the speedometer and has four bars
to provide distance and system
information.

The following describes how the UFRPA front display lights appear as the
vehicle gets closer to a detected object:Description Metric English
one amber bar 1.2 m 4 ft
two amber bars 1.0 m 40 in
three amber bars 0.6 m 23 in
three amber bars and one red bar 0.3 m 1 ft
Turning the System On and Off
The UFRPA system can be turned
on and off by pressing 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.
When the System Does Not
Seem to Work Properly
If UFRPA does not turn on due to a
temporary condition, the message
PARK ASSIST OFF displays on the
DIC, and the light on the park assist
button turns off. This can occur
under the following conditions:
.The ultrasonic sensors are
not clean. Keep the vehicle's
bumpers free of mud, dirt, snow,
ice and slush. For cleaning
instructions, see Exterior Care
on page 10‑101.
.A trailer was attached to the
vehicle, or an object was
hanging out of the liftgate during
the last drive cycle. Once the
attached object is removed,
UFRPA will return to normal
operation.
.If an object is attached to the
front of the vehicle.
.A tow bar is attached to the
vehicle.
.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.

Lift the cover away from base.
7. Lift the air cleaner/filter base todisengage from three pins.
Low-Beam Headlamps/Daytime
Running Lamps (DRL),
High-Beam Headlamps (Base)
1. From the back side of theheadlamp assembly, remove the
top cap to replace the low-beam
headlamp/DRL bulb.
2. From the back side of theheadlamp assembly, remove
the bottom cap to replace the
high-beam headlamp bulb.
3. Disconnect electrical connector.
4. Remove the bulb socket from the headlamp assembly.
5. Replace the bulb in the bulb socket.

Vehicle Care 10-63
Vehicles with P235/65R18,
P235/55R20, or 235/55R20 size
tires require inflation pressure
adjustment when driving
your vehicle at speeds of
160 km/h (100 mph) or higher.
Set the cold inflation pressure to
the maximum inflation pressure
shown on the tire sidewall,
or 260 kPa (38 psi), whichever
is lower. When you end this
high-speed driving, return the tires
to the cold tire inflation pressure
shown on the Tire and Loading
Information label. SeeVehicle
Load Limits on page 9‑12 and
Tire Pressure on page 10‑61.
You will find the maximum load and
inflation pressure molded on the
tire's sidewall, in small letters,
near the rim flange. It will read
something like this: Maximum load
690 kg (1521 lbs) 300 kPa (44 psi)
Max. Press.Tire Pressure Monitor
System
The Tire Pressure Monitor System
(TPMS) uses radio and sensor
technology to check tire pressure
levels. The TPMS sensors monitor
the air pressure in your tires and
transmit tire pressure readings to
a receiver located in the vehicle.
Each tire, including the spare
(if provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on
the vehicle placard or tire inflation
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or
tire inflation pressure label, you
should determine the proper tire
inflation pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a
tire pressure monitoring system
(TPMS) that illuminates a low tire pressure telltale when one or
more of your tires is significantly
under‐inflated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them
to the proper pressure. Driving on
a significantly under‐inflated tire
causes the tire to overheat and can
lead to tire failure. Under‐inflation
also reduces fuel efficiency and
tire tread life, and may affect the
vehicle's handling and stopping
ability.
Please note that the TPMS is
not a substitute for proper tire
maintenance, and it is the driver's
responsibility to maintain correct
tire pressure, even if under‐inflation
has not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been
equipped with a TPMS malfunction
indicator to indicate when the
system is not operating properly.
