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
air flow selector in the O (OFF) position.
•Do not put objects under the front seats that will interfere with the
airflow to the rear seats.
•Remove any snow, ice or leaves from the air intake area at the base of
the windshield.
•To improve the A/C cool down, drive with the windows slightly open
for 2–3 minutes after start up or until the vehicle has been “aired out.”
For maximum cooling performance (MAX A/C) in MAX A/C mode:
•Move the temperature control to the coolest setting.
•Set the fan to the highest speed initially, then adjust in order to
maintain comfort.
To aid in side window defogging and demisting in cold weather:
1. Select

the foglamps. The foglamps can be
turned on only when the headlamp

turned on.
In autolamp mode, the foglamps
won’t be operational until lighting
conditions warrant the activation of the headlamp/parklamp lighting.
Pull headlamp control towards you to turn foglamps on. The foglamp
indicator light
will illuminate when the switch is pulled and the
parklamps are on.
Daytime running lamps (DRL) (if equipped)

To activate:
•the ignition must be in the ON position,
•the headlamp control is in the OFF or parking lamp position and
•the parking brake must be disengaged.
Always remember to turn on your headlamps at dusk or during
inclement weather. The Daytime Running Lamp (DRL) system
does not activate the tail lamps and generally may not provide
adequate lighting during these conditions. Failure to activate your
headlamps under these conditions may result in a collision.

the headlamp(s) through the vents, there is a possibility that
condensation can occur. This condensation is normal and will clear
within 45 minutes of headlamp operation.
Replacing exterior bulbs
Check the operation of all the bulbs frequently.
