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.
Do not turn the engine off when the vehicle is moving.
This will cause a loss of power assist in the brake and
steering systems and disable the airbags.
In an emergency:1. Brake using a firm and steady pressure. Do not pump the brakes repeatedly. This may deplete
power assist, requiring increased brake pedal
force.
2. Shift the vehicle to N (Neutral). This can be done while the vehicle is moving. After shifting to
N (Neutral), firmly apply the brakes and steer the
vehicle to a safe location.
3. Come to a complete stop, shift to P (Park), and turn the ignition to LOCK/OFF. On vehicles with
an automatic transmission, the shift lever must
be in P (Park) to turn the ignition switch to the
LOCK/OFF position.
4. Set the parking brake. See Parking Brake
on
page 3‑26. 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 Messageson page 4‑49for more
information.

DIC Operation and Displays
on page 4‑42for more
information.
When the System Does Not Seem to
Work Properly
SERVICE PARK ASSIST: If this message occurs, take
the vehicle to your dealer to repair the system.
PARK ASSIST OFF: If the URPA system does not
activate due to a temporary condition, the message
displays on the DIC, see DIC Operation and Displays
on page 4‑42for more information. This can occur
under the following conditions:
.The driver disables the system.
.The ultrasonic sensors are not clean. Keep the
vehicle's rear bumper free of mud, dirt, snow, ice
and slush. For cleaning instructions, see Washing
Your Vehicle on page 6‑102.
.A trailer was attached to the vehicle, or a bicycle or
an object was hanging out of the trunk during the
last drive cycle. Once the object is removed, URPA
will return to normal operation.
.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.
If the system is still disabled, after driving forward at
least 40 km/h (25 mph), take the vehicle to your dealer.
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. (Continued)

Malfunctions often are indicated by the system before
any problem is apparent. Being aware of the light can
prevent more serious damage to the vehicle. This
system assists the service technician in correctly
diagnosing any malfunction.
Notice:If the vehicle is continually driven with this
light on, after a while, the emission controls might
not work as well, the vehicle fuel economy might
not be as good, and the engine might not run as
smoothly. This could lead to costly repairs that
might not be covered by the vehicle warranty.
Notice: Modifications made to the engine,
transmission, exhaust, intake, or fuel system
of the vehicle or the replacement of the original
tires with other than those of the same Tire
Performance Criteria (TPC) can affect the vehicle's
emission controls and can cause this light to come
on. Modifications to these systems could lead to
costly repairs not covered by the vehicle warranty.
This could also result in a failure to pass a required
Emission Inspection/Maintenance test. See
Accessories and Modifications on page 6‑3.
This light comes on during a malfunction in one of
two ways:
Light Flashing: A misfire condition has been detected.
A misfire increases vehicle emissions and could
damage the emission control system on the vehicle.
Diagnosis and service might be required. To prevent more serious damage to the vehicle:
.Reduce vehicle speed.
.Avoid hard accelerations.
.Avoid steep uphill grades.
.If towing a trailer, reduce the amount of cargo
being hauled as soon as it is possible.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park the vehicle.
Turn the vehicle off, wait at least 10 seconds, and
restart the engine. If the light is still flashing, follow the
previous steps and see your dealer for service as soon
as possible.
Light On Steady: An emission control system
malfunction has been detected on the vehicle.
Diagnosis and service might be required.
The following may correct an emission system
malfunction:
.Make sure the fuel cap is fully installed. See Filling
the Tankon page 6‑9. The diagnostic system
can determine if the fuel cap has been left off or
improperly installed. A loose or missing fuel cap
allows fuel to evaporate into the atmosphere. A few
driving trips with the cap properly installed should
turn the light off.

5. Install the coolant recovery tank cap and thepressure cap. After a day or two of driving, when
the engine is cold, check the coolant level in the
recovery tank. If it is low, refill it to the COLD
FILL line.
If the coolant in the recovery tank is constantly low, you
should have a dealer service department inspect the
vehicle for leaks.
Notice: If the pressure cap is not tightly installed,
coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.
Engine Overheating
The vehicle has several indicators to warn of engine
overheating.
You will find a warning light about a hot engine as
well as an engine coolant temperature gauge on the
instrument panel cluster. You may decide not to lift the hood when this warning
appears, but instead get service help right away. See
Roadside Assistance Program on page 8‑7.
If you do decide to lift the hood , make sure the vehicle
is parked on a level surface.
Then check to see if the engine cooling fans are
running. If the engine is overheating, both fans should
be running. If they are not, do not continue to run the
engine and have the vehicle serviced.
Notice:
Engine damage from running the engine
without coolant is not covered by the warranty.
Notice: If the engine catches fire while driving
with no coolant, the vehicle can be badly damaged.
The costly repairs would not be covered by the
vehicle warranty. See Overheated Engine Protection
Operating Mode
