Do not attach a microphone or any other device or
object around the part where the curtain shield airbag
activates such as on the windshield glass, side door
glass and front and side pillar. When the curtain
shield airbag inflates, the microphone or other device
or object will be thrown with great force or the curtain
shield airbag may not activate correctly, resulting in
death or serious injury.
Do not use seat accessories which cover the parts
where the side airbags inflate. Such accessories may
prevent the side airbags from activating correctly,
causing death or serious injury.
Do not modify or remove any wiring. Do not modify,
remove, strike or open any components, such as the
steering wheel pad, steering wheel, column cover,
front passenger airbag cover, front seats or airbag
sensor assembly. Doing so may cause sudden SRS
front airbags inflation or disable the system, which
could result in death or serious injury.
Do not modify or replace the seats or upholstery of
front seats with side airbags. Such changes may
disable the system or cause the side airbags to inflate
accidentally, resulting in death or serious injury.
Do not disassemble or repair the front pillar and roof
side containing the curtain shield airbags. Such
changes may disable the system or cause the curtain
shield airbags to inflate accidentally, resulting in

(d) Operating tips
To help cool down the interior after parking in the hot sun,
drive for the first few minutes with the windows open. After
the excess heat has blown away, close the windows.
Make sure the air inlet grilles in front of the windshield are
not blocked by leaves or other obstructions.
If air flow control is not satisfactory, check the dashboard
vents. (See ºCenter ventsº and ºSide ventsº.)
On humid days, do not blow cold air on the windshield. The
windshield could fog up because of the difference in air
temperature on the inside and outside of the windshield.
Keep the area under the front seats clear to allow air to
circulate throughout the vehicle.
On cold days, set the fan speed selector to adjust the fan
speed high for a minute to help clear the intake ducts of
snow or moisture. This can reduce the amount of fogging
on the windows.
When driving on dusty roads, close all windows. If dust
thrown up by the vehicle is still drawn into the vehicle after
closing the windows, it is recommended that the air intake
control button be left to the OUTSIDE AIR mode and the fan
speed control dial be turned to anywhere except the ºOFFº
button.
If following another vehicle on a dusty road, or driving in
windy and dusty conditions, it is recommended that the air
intake control button be temporarily pressed in to the
RECIRCULATED AIR m ode, which will close off the outside
passage and prevent outside air and dust from entering the
vehicle interior.
