Inadvertent Power Battery Saver
This feature is designed to protect your vehicle’s
battery against drainage from the interior lamps, or
garage door opener. When the ignition is turned
off, the power to these features will automatically
turn off after 10 minutes. Power will be restored
for an additional 10 minutes if any door is opened,
the trunk is opened or the courtesy lamp switch
is turned on.
Battery Run-Down Protection
This vehicle has a feature to help prevent the
battery from being drained, if the interior courtesy
lamps, reading/map lamps, visor vanity lamps
or trunk lamp are accidentally left on. If any
of these lamps are left on, they will automatically
turn off after 10 minutes, if the ignition is off.
The lamps will not come back on again until one

Ultrasonic Rear Parking
Assist (URPA)
If your vehicle is equipped, the Ultrasonic Rear
Parking Assist (URPA) system is designed to help
you park while in REVERSE (R). It operates only at
speeds less than 5 mph (8 km/h). URPA helps
make parking easier and helps you avoid colliding
with objects such as parked vehicles. The URPA
system detects objects that are close to the rear of
the vehicle which are at least 10 inches (25.4 cm)
off the ground and below hood or trunk level. The
system detects objects up to 8 feet (2.5 m) behind
your vehicle. URPA determines how close these
objects are from your bumper within this area.
Ultrasonic sensors on the rear bumper are used
to detect the distance to the object.
{CAUTION:
The Ultrasonic Rear Park Assist (URPA)
system does not replace driver vision.
URPA does not:
Operate above speeds of
5 mph (8 km/h).
Detect objects more than 8 feet
(2.5 meters) behind the vehicle. This
distance may be less during warmer or
humid weather.
Detect objects that are below the
bumper, underneath the vehicle,
or that are very close to the vehicle.
Detect children, pedestrians, bicyclists,
or pets.
So 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 URPA system,
always check carefully before backing up
by checking behind your vehicle.

When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a
temporary condition, the message PARK ASSIST
OFF will be displayed on the DIC and a red light will
be shown on the rear URPA display when the shift
lever is moved into REVERSE (R). This occurs
under the following conditions:
The driver disables the system. SeeDIC
Controls and Displays on page 212.
The parking brake pedal is pressed.
A trailer was attached to your vehicle, or a
bicycle or an object was hanging out of your
trunk during your last drive when you turned off
the vehicle. If the attached objects are removed
from your vehicle before the start of your next
drive, the system will return to normal operation
unless an object is detected when the vehicle is
shifted into REVERSE (R). If this occurs, URPA
assumes the object is still attached, so you will
have to wait until the vehicle is driven forward
above 15 mph (25 km/h) before URPA will
return to normal operation.
The ultrasonic sensors are not kept clean. So,
be sure to keep your vehicle’s rear bumper free
of mud, dirt, snow, ice, and slush. For cleaning
instructions, seeWashing Your Vehicle on
page 422. If the DIC still displays the PARK
ASSIST OFF message after cleaning the
bumper and driving forward at a speed of at
least 15 mph (25 km/h), see your dealer.
Other conditions that may affect system
performance include vibrations from a
jackhammer or the compression of air brakes
on a very large truck or other mechanical
devices that interfere with URPA performance.
When URPA is disabled without driver action
and the driver attempts to turn URPA back on
using the Driver Information Center (DIC), the
PARK ASSIST ON option will not be selectable
if the necessary conditions stated above for
normal system operation are not met.
As always, drivers should use care when backing
up a vehicle. Always look behind you, being sure to
check for other vehicles, obstructions and blind
spots.

Winter Driving
Here are some tips for winter driving:
Have your vehicle in good shape for winter.
You may want to put winter emergency
supplies in your trunk.
Also seeTires on page 385.Include an ice scraper, a small brush or broom, a
supply of windshield washer uid, a rag, some
winter outer clothing, a small shovel, a ashlight,
a red cloth, and a couple of reective warning
triangles. And, if you will be driving under severe
conditions, include a small bag of sand, a
piece of old carpet, or a couple of burlap bags
to help provide traction. Be sure you properly
secure these items in your vehicle.

If you put things inside your vehicle, like suitcases,
tools, packages, or anything else, they will go
as fast as the vehicle goes. If you have to stop or
turn quickly, or if there is a crash, they will
keep going.
{CAUTION:
Things you put inside your vehicle can
strike and injure people in a sudden stop
or turn, or in a crash.
Put things in the trunk of your vehicle.
In a trunk, put them as far forward as
you can. Try to spread the weight
evenly.
Never stack heavier things, like
suitcases, inside the vehicle so that
some of them are above the tops of
the seats.
Do not leave an unsecured child
restraint in your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Automatic Level Control
This feature keeps the rear of your vehicle level
as the load changes. It is automatic, you do
not need to adjust anything. This type of level
control is fully automatic and will provide a better
leveled riding position as well as better handling
under a variety of passenger and loading
conditions. An air compressor connected to the
rear shocks will raise or lower the rear of the
vehicle to maintain proper vehicle height.
The system is activated when the ignition key is
turned to RUN and will automatically adjust vehicle
height thereafter. The system may exhaust
(lower vehicle height) for up to ten minutes after
the ignition key has been turned to OFF. You may
also hear the air compressor operating when
the height is being adjusted.

Trailer Wiring Harness
All of the electrical circuits required for your trailer
lighting system can be accessed at the driver’s
side rear lamp connector. This connector is located
under the carpet on the rear corner of the trunk
compartment.
Driving with a Trailer
Towing a trailer requires a certain amount of
experience. Before setting out for the open road,
you will want to get to know your rig. Acquaint
yourself with the feel of handling and braking with
the added weight of the trailer. And always
keep in mind that the vehicle you are driving is
now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check all trailer hitch parts and
attachments, safety chains, electrical connector,
lamps, tires and mirror adjustment. If the trailer
has electric brakes, start your vehicle and
trailer moving and then apply the trailer brake
controller by hand to be sure the brakes are
working. This lets you check your electrical
connection at the same time.During your trip, check occasionally to be sure
that the load is secure, and that the lamps and any
trailer brakes are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead
as you would when driving your vehicle without
a trailer. This can help you avoid situations
that require heavy braking and sudden turns.
Passing
You will need more passing distance up ahead
when you are towing a trailer. And, because
the vehicle is a good deal longer, you will need to
go much farther beyond the passed vehicle
before you can return to your lane.

Filling a Portable Fuel Container
{CAUTION:
Never ll a portable fuel container while it
is in your vehicle. Static electricity
discharge from the container can ignite the
gasoline vapor. You can be badly burned
and your vehicle damaged if this occurs.
To help avoid injury to you and others:
Dispense gasoline only into approved
containers.
Do not ll a container while it is inside a
vehicle, in a vehicle’s trunk, pickup
bed, or on any surface other than the
ground.
Bring the ll nozzle in contact with the
inside of the ll opening before
operating the nozzle. Contact should
be maintained until the lling is
complete.
Do not smoke while pumping gasoline.
Checking Things Under
the Hood
{CAUTION:
An electric fan under the hood can start up
and injure you even when the engine is not
running. Keep hands, clothing, and tools
away from any underhood electric fan.
{CAUTION:
Things that burn can get on hot engine
parts and start a re. These include
liquids like fuel, oil, coolant, brake uid,
windshield washer and other uids, and
plastic or rubber. You or others could be
burned. Be careful not to drop or spill
things that will burn onto a hot engine.
