Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
Do not drive at any one constant speed, fast or
slow, for the rst 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting to
brake or slow the vehicle.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time the new brake
linings are not yet broken in. Hard stops
with new linings can mean premature wear and
earlier replacement. Follow this breaking-in
guideline every time you get new brake linings.
Do not tow a trailer during break-in. SeeTowing
a Trailer on page 4-27for the trailer towing
capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.

Automatic Transmission Operation
The automatic transmission may have a shift lever
located either on the steering column or on the console
between the seats.
There are several different positions for the shift lever.
PARK (P):This position locks the front wheels. It is the
best position to use when you start the engine because
your vehicle cannot move easily.{CAUTION:
It is dangerous to get out of the vehicle if the
shift lever is not fully in P (Park) with the
parking brake rmly set. The vehicle can roll.
Do not leave the vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure the
vehicle will not move, even when you are on
fairly level ground, always set the parking brake
and move the shift lever to P (Park). SeeShifting
Into Park on page 2-31. If you are pulling a
trailer, seeTowing a Trailer on page 4-27.
Make sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transmission shift lock control system. You have to fully
apply your regular brakes before you can shift from
PARK (P) while the ignition key is in ON/RUN. If you
cannot shift out of PARK (P), ease pressure on the shift
lever. Push the shift lever all the way into PARK (P)
as you maintain brake application. Then move the shift
lever into another gear. SeeShifting Out of Park on
page 2-33.
2-27

Downshifting the transmission in slippery road conditions
could result in skidding, see Skidding underLoss of
Control on page 4-10.
Notice:Driving your vehicle if you notice that it is
moving slowly or not shifting gears as you increase
speed may damage the transmission. Have your
vehicle serviced right away. You can drive in
SECOND (2) when you are driving less than 35 mph
(55 km/h) and DRIVE (D) for higher speeds until then.
DRIVE (D) can be used for towing. You may want to
shift the transmission to THIRD (3) or, if necessary, to a
lower gear if the transmission shifts too often under
heavy loads and/or hilly conditions.
SeeTowing a Trailer on page 4-27for more information.
THIRD (3):This position is also used for normal driving.
However, it reduces vehicle speed more than DRIVE (D)
without using your brakes. You might choose THIRD (3)
instead of DRIVE (D) when driving on hilly, winding
roads, when towing a trailer, so there is less shifting
between gears and when going down a steep hill.
SECOND (2):This position reduces vehicle speed more
than THIRD (3) without using your brakes. You can
use SECOND (2) on hills. It can help control your speed
as you go down steep mountain roads, but then you
would also want to use your brakes off and on.Notice:Do not shift into SECOND (2) unless you
are going slower than 65 mph (105 km/h), or you can
damage your engine and/or transmission.
FIRST (1):This position reduces vehicle speed even
more than SECOND (2) without using your brakes.
You can use it on very steep hills, or in deep snow or
mud. If the shift lever is put in FIRST (1) while the
vehicle is moving forward, the transmission will not shift
into rst gear until the vehicle is going slowly enough.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transmission. The repair will
not be covered by your warranty. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
Performance Shifting
If your vehicle has this feature, it can detect a change in
driving patterns. If you make an aggressive driving
maneuver, the vehicle’s transmission automatically
shifts to the lowest possible gear to maximize vehicle
performance. The vehicle will automatically return to
normal operation when you return to normal driving
patterns.
2-29

Parking Brake
The parking brake pedal is
located to the left of the
regular brake pedal,
near the driver’s door.
To set the parking brake, hold the regular brake pedal
down with your right foot and push the parking brake
pedal down with your left foot.
If the ignition is on, the brake system warning light on
the instrument panel cluster should come on. If it
does not, you need to have your vehicle serviced.A warning chime will sound if the parking brake is set,
the ignition is on, and the vehicle speed is greater
than 5 mph (8 km/h). The brake light will come on and
stay on until the parking brake is released. See
Brake System Warning Light on page 3-60for more
information.
To release the parking brake, hold the regular brake
pedal down with your right foot and push the parking
brake pedal down with your left foot. When you lift your
left foot, the parking brake pedal will follow it to the
released position.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Make sure
that the parking brake is fully released and the brake
warning light is off before driving.
If you are towing a trailer and are parking on any hill,
seeTowing a Trailer on page 4-27.
2-30

Shifting Into Park
{CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
If you have left the engine running, the vehicle
can move suddenly. You or others could be
injured. To be sure your vehicle will not move,
even when you are on fairly level ground, use
the steps that follow. If you are pulling a trailer,
seeTowing a Trailer on page 4-27.
Steering Column Shift Lever
If your vehicle has a steering column shift lever, use this
procedure to shift the vehicle into PARK (P):
1. Hold the brake pedal down with your right foot.
2. Move the shift lever into PARK (P) by pulling the
shift lever toward you and moving it up as far as it
will go.3. With your right foot still holding the brake pedal
down, set the parking brake. SeeParking Brake
on page 2-30for more information.
4. Turn the ignition key to LOCK/OFF.
5. Remove the key and take it with you. If you can
leave your vehicle with the ignition key in your
hand, your vehicle is in PARK (P).
Console Shift Lever
If your vehicle is equipped with a console shift lever,
use this procedure to shift the vehicle into PARK (P):
1. Hold the brake pedal down with your right foot.
2. Move the shift lever into PARK (P) by pushing the
lever all the way toward the front of your vehicle
and then to the left.
3. With your right foot still holding the brake pedal
down, set the parking brake. SeeParking Brake
on page 2-30for more information.
4. Turn the ignition key to LOCK/OFF.
5. Remove the key and take it with you. If you can
leave your vehicle with the ignition key in your
hand, your vehicle is in PARK (P).
2-31

Running the Vehicle While Parked
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier caution under
Engine Exhaust on page 2-34.
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the climate control fan is at the highest setting.
One place this can happen is a garage.
Exhaust — with CO — can come in easily.
NEVER park in a garage with the engine
running.
Also see “If You Are Caught in a Blizzard” under
Winter Driving on page 4-16.
{CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
Do not leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle will not move, even when you are on
fairly level ground, always set the parking brake
after you move the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle will not
move. SeeShifting Into Park on page 2-31.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer on page 4-27.
2-35

When the System Does Not Seem to
Work Properly
The driver disables the system.
The parking brake pedal is depressed.
The ultrasonic sensors are not kept clean. So be
sure to keep your vehicle’s front and rear bumpers
free of mud, dirt, snow, ice and slush. For cleaning
instructions, seeWashing Your Vehicle on
page 5-94.
A trailer was attached to your vehicle, or a bicycle or
an object was hanging out of your trunk during your
last drive cycle, the red light may illuminate in the
rear display. Once the attached object is removed,
UFRPA will return to normal operation.
A tow bar is attached to your vehicle.
The vehicle’s bumper is damaged. Take the vehicle
to your dealer/retailer 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 15 mph (25 km/h), take your vehicle to your
dealer/retailer.
Side Blind Zone Alert (SBZA)
Your vehicle may have a Side Blind Zone Alert (SBZA)
system. Read this entire section before using the system.
The SBZA system operates on a radio frequency
subject to Federal Communications Commission (FCC)
Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.

2-43

The manufacturer is not responsible for any radio or TV
interference caused by unauthorized modications to
this equipment. Such modications could void the user’s
authority to operate the equipment.
{CAUTION:
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.
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 will light up in your side mirrors.
This indicates that it may be unsafe for you 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, 11 ft. or 3.5 m.
This zone starts at each side mirror and goes back
approximately 16 ft. (5.0 m). The height of the zone is
approximately between 1.5 ft. (0.5 m) and 6 ft. (2.0 m) off
the ground.
The SBZA detection zones do not change if your
vehicle is towing a trailer. So be extra careful when
changing lanes while towing a trailer.
2-44

How the System Works
When the vehicle is started, both outside mirror displays
will briey come on to indicate that the system is
operating. When you are driving forward, the left or right
side mirror SBZA display will light up if a vehicle is
detected in that blind zone. If you activate a turn signal
and a vehicle has been detected on the same side, the
SBZA display will ash to give you extra warning not to
change lanes.
SBZA displays do not come on while your vehicle is
approaching or passing other vehicles. At speeds greater
then 20 mph (32 km/h), 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). SeeDriver Information Center (DIC) on
page 3-70for 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 your vehicle to your dealer/retailer.
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, your 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, seeWashing Your Vehicle on page 5-94.
If the DIC still displays the CLEAN SIDE BLIND
ZONE ALERT SYSTEM message after cleaning the
bumper, see your dealer/retailer.
The SBZA displays may remain on if a trailer is attached
to your vehicle, or a bicycle or object is extending out
to either side of the vehicle. Left Side Mirror Display

Using Adaptive Cruise Control on Hills
and When Towing a Trailer
How well Adaptive Cruise Control will work on hills
and when towing a trailer depends on your vehicle’s
speed, vehicle load, traffic conditions and the steepness
of the hills. It may not detect a vehicle in your lane
while driving on hills. When going up steep hills, you
may want to use the accelerator pedal to maintain your
vehicle’s speed. When going downhill, especially
when towing a trailer, you may want to brake to keep
your speed down. Applying the brake disengages
the system. You may choose not to use Adaptive Cruise
Control on steep hills, especially when towing a trailer.
Disengaging Adaptive Cruise Control
To turn off the system, apply the brake pedal,
press the cancel button, or press the Adaptive
Cruise Control button.
Erasing Set Speed Memory
Press the Adaptive Cruise Control button or turn the
ignition off.
Other Messages
There are three additional messages that may appear
on the DIC. They are SERVICE RADAR CRUISE,
RADAR CRUISE NOT READY and CLEAN RADAR.
These messages will appear to indicate a problem with
the Adaptive Cruise Control. SeeDIC Warnings and
Messages on page 3-75for more information.
Cleaning the System
The radar can become blocked by snow, ice, or dirt.
If so, you may need to turn off the engine and clean the
lens. Remember, do not use Adaptive Cruise Control
in icy conditions, or when visibility is low, such as in fog,
rain or snow.
The emblem/lens is located in the center of the grille.
To clean the emblem/lens, wipe the surface with a
soft cloth. After cleaning the emblem/lens, try to engage
the Adaptive Cruise Control. If you are unable to do
so, see your dealer/retailer.
