Object Detection Systems
Ultrasonic Rear Parking
Assist (URPA)
For vehicles with the Ultrasonic Rear Parking Assist
(URPA) system, it operates at speeds less than 5 mph
(8 km/h), 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 8 feet (2.5 m) behind the vehicle, and
at least 10 inches (25.4 cm) off the ground.
{CAUTION:
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 if they are too close or far from
the vehicle
children, pedestrians, bicyclists, or pets.
CAUTION: (Continued)
CAUTION: (Continued)
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.
The display is located near
the passenger side rear
window and can be
seen by looking over your
right shoulder.
URPA uses three color-coded lights to provide distance
and system information.

Luggage Carrier
Notice:Loading cargo on the luggage carrier that
weighs more than 200 lbs (91 kg) or hangs over
the rear or sides of the vehicle can damage
the vehicle. Load cargo so that it rests on the slats
as far forward as possible and against the side
rails, making sure to fasten it securely.
For vehicles with a luggage carrier, items can be loaded
on top of the vehicle.
The luggage carrier has siderails attached to the roof.
It can also have crossrails which can be moved
back and forth to help secure cargo. Tie the load to the
siderails or siderail supports.
Do not exceed the maximum vehicle capacity when
loading the vehicle. For more information on vehicle
capacity and loading, seeLoading the Vehicle on
page 4-34.
Make sure the cargo is properly loaded.
To prevent damage or loss of cargo while driving,
periodically stop and check to make sure cargo is still
securely fastened.
If small heavy objects are placed on the roof, cut a
piece of 3/8 inch plywood to t inside the crossrails
and siderails to spread the load. Tie the plywood
to the siderail supports.
Tie the load and secure it to the crossrails or the
siderail supports. Use the crossrails only to keep
the load from sliding. To move a crossrail,
lift the release lever up, on both sides of the rail.
Then slide the crossrail to the desired position
balancing the force side to side. Press the release
lever down on both sides of the rail, down to
tighten it. Try to slide the crossrail back and forth
slightly to make sure it is tight.
To carry long items, move the crossrails as far
apart as possible. Tie the load to the crossrails and
the siderails or siderail supports. Also tie the
load to the bumpers, but do not tie the load so
tightly that the crossrails or siderails are damaged.
After moving a crossrail, be sure it is securely
locked into the siderail.
A Center High-Mounted Stoplamp (CHMSL) is located
above the rear window glass.
Make sure items loaded on the roof of the vehicle do
not block or damage the CHMSL.
Rear Seat Armrest
Vehicles with a rear seat armrest, have two cupholders.
Pull the armrest down from the rear seatback to
access the cupholders.

When the heated windshield washer uid system is
activated under certain outside temperature conditions,
steam may ow out of the washer nozzles for a short
period of time before washer uid is sprayed. This is a
normal condition.
HEATING WASH FLUID WASH WIPES PENDING is
displayed on the DIC when the washer system is heating
the uid. WASHER FLUID LOW ADD FLUID is displayed
when the washer uid is low. SeeDIC Warnings and
Messages on page 3-66.
Cruise Control
{CAUTION:
Cruise control can be dangerous where you cannot
drive safely at a steady speed. So, do not use the

Reading Lamps
For vehicles with reading lamps, they are located on the
overhead console.
To turn on the reading lamps, press the button located
next to each lamp. To turn them off, press the button
again.
The vehicle may also have reading lamps in other
locations. To turn the lamps on or off, press the button
located next to the lamp.
If the vehicle has a DVD Rear Seat Entertainment (RSE)
system, press the lamp lenses to turn the lamps on or off.
The lamps are xed and cannot be adjusted.
Cargo Lamp
The cargo lamps come on by turning the instrument panel
brightness control knob to the farthest clockwise position.
This knob is located on the instrument panel and also
turns on the dome lamps.
The cargo lamp can be used if more light is needed
in the cargo area of the vehicle or in the top-box
storage units.
Electric Power Management
The vehicle has Electric Power Management (EPM) that
estimates the battery’s temperature and state of charge.
It then adjusts the voltage for best performance and
extended life of the battery.
When the battery’s state of charge is low, the voltage is
raised slightly to quickly bring the charge back up. When
the state of charge is high, the voltage is lowered slightly
to prevent overcharging. If the vehicle has a voltmeter
gage or a voltage display on the Driver Information
Center (DIC), you may see the voltage move up or down.
This is normal. If there is a problem, an alert will be
displayed.
The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles. This is
because the generator (alternator) may not be spinning
fast enough at idle to produce all the power that is
needed for very high electrical loads.
A high electrical load occurs when several of the following
are on, such as: headlamps, high beams, fog lamps, rear
window defogger, climate control fan at high speed,
heated seats, engine cooling fans, trailer loads, and loads
plugged into accessory power outlets.
