Introduction

Static can be caused on AM stations by power lines, electric fences,
traffic lights and thunderstorms. Moving away from an interfering
structure (out of its“shadow”) returns your reception to normal.
•Station overload.Weak signals are sometimes captured by stronger
signals when you pass a broadcast tower. A stronger signal may
temporarily overtake a weaker signal and play while the weak station
frequency is displayed.
Principles of GPS (global positioning system) operation
Your system directs you based on information derived from global
positioning satellites, road maps stored on the DVD, sensors in your
vehicle and the desired destination. The system compiles all necessary
information to guide you to your selected destination. Space satellites
determine the vehicle’s current location and transmit position and time
signals to your car.
If the vehicle has been parked for a long period of time, the navigation
function may be temporarily unresponsive. The navigation system will
operate reliably again once GPS reception is available for a few minutes.
Limited GPS reception
System performance may be adversely affected if GPS reception is
interrupted or interference occurs over a distance of several miles. The
following are possible causes for GPS reception being interrupted. If the
vehicle is:
•in multi-story parking garages
•in tunnels and under bridges
•inside or in between buildings
•by forests or tree-lined avenues
•in heavy rain showers and thunderstorms
•in valleys and in mountainous regions
•roads under cliffs
Ensure that you do not have any metal objects on the rear parcel shelf
and that if your windows are tinted, they use non-metal tinting instead of
metal oxide tinting. Both of these factors can also interrupt GPS
reception.
Cleaning the display
Do not spray cleaning fluid directly onto the unit. Instead, spray onto a
soft cloth and gently wipe the unit. Only recommended products should
be used.

Press to toggle between Fahrenheit
and Celsius temperature on the
DEATC display only. The set point
temperatures in Celsius will be displayed in half-degree increments.
OPERATING TIPS
•To reduce fog build up on the windshield during humid weather, place
the air flow selector in the
position.
•To reduce humidity build up inside the vehicle: do not drive with the
recirculation control on or the system turned off.
•Do not put objects under the front seats that will interfere with the
airflow to the back seats.
•Remove any snow, ice or leaves from the air intake area at the base of
the windshield.
To aid in side window defogging/demisting in cold weather:
1. Select
2. Select A/C
3. Modulate the temperature control to maintain comfort.
4. Set the fan speed to HI
5. Direct the outer instrument panel vents towards the side windows
To increase airflow to the outer instrument panel vents, close the vents
located in the middle of the instrument panel.
Do not place objects on top of the instrument panel as these
objects may become projectiles in a collision or sudden stop.

PERIMETER ALARM SYSTEM (IF EQUIPPED)
The perimeter anti-theft system will help prevent your vehicle from
unauthorized entry.
If there is any potential perimeter anti-theft problem with your vehicle,
ensureALL remote entry transmittersare taken to the dealership to
aid in troubleshooting.
Your perimeter alarm system may include an interior motion detection
system (intrusion sensing). The interior motion detection system detects
an unauthorized vehicle entry by sensing movement within the vehicle.
The interior motion detection system will operate only when the
vehicle is locked using the remote keyless entry (keypad or
remote transmitters). If you lock the vehicle using the key in the
driver’s door key cylinder, the perimeter alarm will arm, but the
interior motion detection system will not arm.
Do not arm the interior motion detection system if movement within the
vehicle is likely to occur (i.e. a pet is left inside the vehicle).
For proper operation of the interior motion detection system, close all
windows and moonroof prior to arming the system. This will prevent
accidental alarm activation caused by external influences and ensure
proper interior motion detection.
Arming the system
When armed, the perimeter alarm will notify you of an unauthorized
entry. When unauthorized entry occurs, the system will flash the park
lamps and will sound the horn.
The system is ready to arm whenever the key is out of the ignition. Any
of the following actions will arm the alarm system:
•Press the remote transmitter lock control one time to arm the system.
•Lock all doors using the keypad.
•Lock all doors using the interior power lock switch while the driver or
passenger door is open and then closed.
•Lock all doors with the key in the key lock cylinder (this willnotarm
the interior motion detection system, if equipped).
The park lamps will flash once and the horn will chirp once if all the
closures are closed.
If any closure is not properly closed, the park lamps will not flash and
the horn will chirp twice.
The system will wait 20 seconds after one of the actions is performed
before allowing an alarm to go off. After the 20–second pre-arm phase,

Starting the engine
1. Turn the key to 4 (ON) without
turning the key to 5 (START). If
there is difficulty in turning the key,
rotate the steering wheel until the
key turns freely.
2. Turn the key to 5 (START), then
release the key as soon as the
engine starts. Excessive cranking
could damage the starter.
Note:If the engine does not start within five seconds on the first try,
turn the key to 3 (OFF), wait 10 seconds and try again.
Using the engine block heater (if equipped)
Use of an engine block heater is strongly recommended if you live in a
region where temperatures reach -23°C (-10°F) or below. For best
results, plug the heater in at least three hours before starting the vehicle.
The heater can be plugged in the night before starting the vehicle.
To reduce the risk of electrical shock, do not use your heater
with ungrounded electrical systems or two-pronged (cheater)
adapters.
Guarding against exhaust fumes
Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.
If you smell exhaust fumes inside your vehicle, have your dealer
inspect your vehicle immediately. Do not drive if you smell
exhaust fumes.
Important ventilating information
If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least 2.5 cm (one inch) or adjust the heating
or air conditioning to bring in fresh air.
