Replacing Restraint System Parts
After a Crash
{WARNING:
A crash can damage the restraint systems in your
vehicle. A damaged restraint system may not
properly protect the person using it, resulting in
serious injury or even death in a crash. To help
make sure your restraint systems are working
properly after a crash, have them inspected and
any necessary replacements made as soon as
possible.
If the vehicle has been in a crash, do you need new
safety belts or LATCH system (if equipped) parts?
After a very minor crash, nothing may be necessary.
But the safety belt assemblies that were used during
any crash may have been stressed or damaged. See
your dealer to have the safety belt assemblies
inspected or replaced. If the vehicle has the LATCH system and it was being
used during a crash, you may need new LATCH system
parts.
New parts and repairs may be necessary even if the
safety belt or LATCH system (if equipped), was not
being used at the time of the crash.
If an airbag inflates, you will need to replace airbag
system parts. See the part on the airbag system earlier
in this section.
Have the safety belt pretensioners checked if the
vehicle has been in a crash, if the airbag readiness light
stays on after the vehicle is started, or while you are
driving. See
Airbag Readiness Light
on page 4‑33.

Ignition Positions
The ignition has four different positions:
In order to shift out of P (Park), ignition must be in
the ON/RUN and the regular brake pedal must be
applied.
Notice:Using a tool to force the key to turn in the
ignition could cause damage to the switch or break
the key. Use the correct key, make sure it is all the
way in, and turn it only with your hand. If the key
cannot be turned by hand, see your dealer.
A (LOCK/OFF): This position locks the ignition. It also
locks the transmission and steering column. This is the
only position in which the ignition key can be inserted or
removed. The steering can bind with the wheels turned off center.
If this happens, move the steering wheel from right to
left while turning the key to ACC/ACCESSORY. If this
doesn't work, then the vehicle needs service.
B (ACC/ACCESSORY):
This position lets the radio
and windshield wipers operate while the engine is off.
To use ACC/ACCESSORY, turn the key clockwise.
C (ON/RUN): This position can be used to operate
electrical accessories and to display some of the
warning and indicator lights. The switch stays in this
position when the engine is running.
If you leave the key in the ACC/ACCESSORY or
ON/RUN position with the engine off, the battery could
be drained. You may not be able to start the vehicle if
the battery is allowed to drain for an extended period
of time.
D (START): This position starts the engine. When the
engine starts, release the key. The ignition switch
returns to ON/RUN for driving.
A warning tone will sound and the Driver Information
Center (DIC) will display DRIVER DOOR OPEN when
the driver door is opened if the ignition is in LOCK/OFF,
ACC/ACCESSORY and the key is in the ignition. See
DIC Warnings and Messages
on page 4‑55for more
information.

2 (Second):This position reduces vehicle speed even
more than 3 (Third) without using the brakes. You can
use 2 (Second) on hills. It can help control vehicle
speed as you go down steep mountain roads, but then
you would also want to use the brakes off and on.
Notice: Driving in 2 (Second) for more than 25 miles
(40 km) or at speeds over 55 mph (90 km/h) may
damage the transmission. Also, shifting into
2 (Second) at speeds above 65 mph (105 km/h) can
cause damage. Drive in 3 (Third) or D (Drive) instead
of 2 (Second).
1 (First): This position reduces vehicle speed even
more than 2 (Second) without using the brakes. You can
use it on very steep hills, or in deep snow or mud. If the
shift lever is put in 1 (First) while going forward, the
transmission will not shift into first 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 the vehicle warranty. If you are stuck, do
not spin the tires. When stopping on a hill, use the
brakes to hold the vehicle in place.Parking Brake
The parking brake pedal
is located to the left of the
regular brake pedal, near
the driver door.
To set the parking brake, hold the regular brake pedal
down, then push the parking brake pedal down.
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 the vehicle serviced.
3-26

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. SeeBrake
System Warning Light
on page 4‑36for more
information.
To release the parking brake, hold the regular brake
pedal down, then push the parking brake pedal down.
When you lift your foot off the parking brake pedal, the
pedal will follow your foot 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,
see Towing a Trailer on page 5‑27.
Shifting Into Park
{WARNING:
It can be dangerous to get out of the vehicle if the
shift lever is not fully in P (Park) with the parking
brake firmly set. The vehicle can roll. 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, use the steps that follow.
If you are pulling a trailer, see Towing a Trailer
on
page 5‑27

Object Detection Systems
Ultrasonic Rear Parking
Assist (URPA)
For vehicles with the URPA system, it operates at
speeds less than 8 km/h (5 mph), 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 2.5 m (8 ft) behind the
vehicle, and at least 25 cm (10 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 if they are 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 (Continued)
WARNING: (Continued)
the vehicle before backing up. While backing, be
sure to look for objects and check the vehicle's
mirrors.
The display is located on
the rear shelf, below the
rear window, and can be
seen by looking over your
right shoulder.
URPA uses three color-coded lights to provide distance
and system information.
How the System Works
URPA comes on automatically when the shift lever is
moved into R (Reverse). The rear display briefly
illuminates to indicate the system is working.
3-37

Side Blind Zone Alert (SBZA)
The vehicle may have a Side Blind Zone Alert (SBZA)
system. Read this entire section before using the
system.
{WARNING:
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 the side
mirrors. This indicates that it may be unsafe 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, 3.5 m (11 ft).
This zone starts at each side mirror and goes back
approximately 5 m (16 ft). The height of the zone is
approximately between 0.5 m (1.5 ft) and 2.0 m (6 ft) off
the ground.
3-39

The SBZA detection zones do not change if the vehicle
is towing a trailer. So be extra careful when changing
lanes while towing a trailer.
How the System Works
Left Side Mirror DisplayRight Side Mirror Display
When the vehicle is started, both outside mirror displays
will briefly come on to indicate that the system is
operating. While 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 flash to give you extra warning not to
change lanes.
SBZA displays do not come on while the 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). See
Driver Information Center (DIC)
on
page 4‑47for 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 the vehicle to your dealer.
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, the 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,
see Washing Your Vehicle
on page 6‑104. If the DIC still
displays the SIDE BLIND ZONE SYS. UNAVAILABLE
message after cleaning the bumper, see your dealer.

How the System Works
LDW uses a camera located between the inside
rearview mirror and the windshield to detect the lane
markings.
@(Lane Departure Warning):To turn LDW on and
off, press the LDW control, located by the exterior
headlamp control. An indicator on the control will light
to indicate that LDW is on.
When the vehicle is started, the LDW symbol, located
in the instrument panel cluster, will briefly come on to
indicate that the light is operational. LDW only operates at speeds of 35 mph (56 km) or
greater. If LDW is turned on when traveling at these
speeds, the LDW symbol will appear green if the
system detects a left or right lane marking. This symbol
will change to amber and flash and three beeps will
sound if you cross a detected lane marking without
using the turn signal.
If the LDW symbol does not appear, LDW is not
currently operating and will not warn you.
To change the volume of the warning chime, see Chime
Volume under
DIC Vehicle Customization
on page 4‑65for more information.
When the System Does Not Seem To Work
Properly
The LDW symbol will not appear when the system is
having difficulty seeing the lines on the road or if the
view of the camera on the windshield is blocked with
mud, dirt, snow, ice, or slush, if the windshield is
damaged, or when weather limits visibility, such as
while driving in fog, rain, or snow conditions. This is
normal operation, the vehicle does not need service.
For cleaning instructions, see Washing Your Vehicle
on
page 6‑104.
