Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is all the way in.
If it is, turn the steering wheel left and right while
you turn the key hard. If none of this works,
then your vehicle needs service.
B (ACC/ACCESSORY):This position lets things like
the radio and the windshield wipers operate while
the engine is off.
Lengthy operation of features such as the radio in the
ACC/ACCESSORY ignition position and the ON/RUN
position may drain the battery and prevent your vehicle
from starting. Do not operate your vehicle in the
ACC/ACCESSORY ignition position for a long period
of time.
C (ON/RUN):This is the position for driving. It is the
position the ignition switch returns to after the engine
starts, and the key is released.
The battery could be drained if you leave the key in
the ACC/ACCESSORY or ON/RUN position with
the engine off. You may not be able to start your
vehicle if the battery is allowed to drain for an extended
period of time.
D (START):This position starts the engine.Key In the Ignition
Never leave your vehicle with the keys inside, as it is an
easy target for joy riders or thieves. If you leave the
key in the ignition and park your vehicle, a chime
will sound, when you open the driver’s door. Always
remember to remove your key from the ignition and take
it with you. This will lock your ignition and transmission.
Also, always remember to lock the doors.
The battery could be drained if you leave the key in the
ignition while your vehicle is parked. You may not be
able to start your vehicle after it has been parked for an
extended period of time.
Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
10 minutes after the engine is turned off:
Audio System
Sunroof
Power Windows
The sunroof and power windows will continue to work
up to 10 minutes after the key is turned to LOCK/OFF or
until any door is opened. The radio will continue to
work for up to 10 minutes after the key is turned
to LOCK/OFF or until the driver’s door is opened.

Outlet Adjustment
Your vehicle has air outlets that let you adjust the
direction and amount of airow inside the vehicle.
Use the thumbwheels located beside the air outlets to
direct the airow up and down. Use the thumbwheels
below the air outlets to direct the air left or right.
Operation Tips

Keep the hood and front air inlets free of ice,
snow, or any other obstruction, such as leaves.
The heater and defroster will work far better,
reducing the chance of fogging the inside of
the windows.
Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
the vehicle.
Adding outside equipment to the front of the
vehicle, such as hood-air deectors, etc., may affect
the performance of the heating and air conditioning
system. Check with your dealer/retailer before
adding equipment to the outside of your vehicle.
Rear Air Conditioning and
Heating System and Electronic
Climate Controls
If your vehicle has this rear climate control system
there are rear seat audio controls located in the
center console.
The rear system can be controlled through the AUX
button on the front climate control panel. Press the
AUX button to turn the rear climate control system
on or off. An indicator light in the AUX button comes
on when the rear climate control system is on. The
direction, temperature, and speed of the airow for
the rear of the vehicle will be the same as those set
for the front of the vehicle.
Use the controls located in the rear of the front console,
to independently control the air ow for the rear of
the vehicle separately from that of the front of the
vehicle. To turn the system on, press any of the rear
air conditioning control buttons, except the
Cbutton.
To turn the system off, press and hold the
Cbutton.
