CHILD RESTRAINT SYSTEM INSTALLATION
Type A:
1. Widen the clearance at the lower seatback and confirm
the position of the lower anchorages below the tag in the
seatback.
2. Latch the hooks of lower straps onto the anchorages
and tighten the lower straps.
Type B:
1. Widen the clearance at the lower seatback and confirm
the position of the lower anchorages below the tag in the
seatback.
2. Latch the buckles onto the anchorages.
If your child restraint system has a top strap, it should be
anchored.
(For the installation of the top strap, see ºUsing a top
strapº on page 159 or 164.)
For the installation details, refer to the instruction manual
equipped with each product.
CAUTION
 When using the lower anchorages for the child
restraint system, be sure that there are no irregular
objects around the anchorages or that the seat belt is
not caught.
 Push and pull the child restraint system in different
directions to be sure it is secure. Follow all the
installation instructions provided by its
manufacturer.
 Do not put a child restraint system on the rear seat if
it interferes with the lock mechanism of the front
seats. This can cause death or severe injury to the
child and front passenger in case of sudden braking
or a collision.

AIR CONDITIONING
187
CAUTION
Do not use the ºFRONT WINDSHIELDº button during
cooled air operation in extremely humid weather. The
difference between the temperature of the outside air
and that of the windshield could cause the outer surface
of the windshield to fog up blocking your vision.
(c) Air filter
The air filter may clog after long use which will reduce the air
flow. However, you can inspect the filter easily.
The air conditioning filter may clog after long use. The filter
may need to be replaced if the air flow of the air conditioner and
heater experiences extreme reductions in operating ef ficiency,
or if the windows become to fog up easily.
When you inspect and replace the air filter, be sure to turn off
the fan.

2. Remove the cover and take out the air filter
If it is dirty, it should be replaced. To maintain the air
conditioning efficiency, replace the air filter according to the
maintenance schedule. (For scheduled maintenance
information, please refer to the ºOwner's Manual Supplement
/ Scheduled Maintenanceº.)
INFORMATION
The air filter should be installed properly in position.The use of air conditioning with the air filter removedmay cause deteriorated dustproof performance andthen affect air conditioning performance.
(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.

the signal becomes weak, the radio reduces the amount of
channel separation to prevent the weak signal from creating
noise. If the signal becomes extremely weak, the radio
switches from stereo to mono reception. In this case, ºSTº
disappears from the display.

Car audio system operating hints
NOTICE
To ensure correct audio system operations:
Be careful not to spill beverages over the audiosystem.
Do not put anything other than a cassette tape orcompact disc into the cassette tape slot or compact
disc slot.
The use of a cellular phone inside or near the vehiclemay cause a noise from the speakers of the audiosystem which you are listening to. However, thisdoes not indicate a malfunction.
Radio reception
Usually, the problem with radio reception does not mean there
is a problem with your radio ± it is just the normal result of
conditions outside the vehicle.
For example, nearby buildings and terrain can interfere with
FM reception. Power lines or telephone wires can interfere
with AM signals. And of course, radio signals have a limited
range. The farther you are from a station, the weaker its signal
will be. In addition, reception conditions change constantly as
your vehicle moves.
Here are some common reception problems that probably do
not indicate a problem with your radio: FM
Fading and drifting stations
± Generally, the effective range
of FM is about 40 km (25 miles). Once outside this range, you
may notice fading and drifting, which increase with the
distance from the radio transmitter. They are often
accompanied by distortion.
Multi±path ± FM signals are reflective, making it possible for
two signals to reach your antenna at the same time. If this
happens, the signals will cancel each other out, causing a
momentary flutter or loss of reception.
Static and fluttering ± These occur when signals are blocked
by buildings, trees, or other large objects. Increasing the bass
level may reduce static and fluttering.
Station swapping ± If the FM signal you are listening to is
interrupted or weakened, and there is another strong station
nearby on the FM band, your radio may tune in the second
station until the original signal can be picked up again.
