1Fan speed at low 2Fan speed at high
The fan speed can be set to your desired speed by turning the
fan speed control dial. The higher the fan speed is, the more
air is delivered. Turning the dial to ºOFFº turns off the fan.
To remove exterior windshield frost, use the high speed
setting.
If manual switching of air intake is desired ±
SV21003
The air intake control button is used to switch the air intake
between the OUTSIDE AIR mode and RECIRCULATED AIR
mode.
With the bu
tton in the OUTSIDE AIR mode, the OUTSIDE AIR
mode indicator light will come on and the system will take fresh
outside air into the vehicle.
If quick circulation of cooled air is desired, push the air intake
control button for RECIRCULATED AIR. The
RECIRCULATED AIR mode indicator light will come on.
For normal use, it is best to keep the air intake control button
set to OUTSIDE AIR mode. If recirculated air is used during
heating, the windows will fog up more easily.

AIR CONDITIONING

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 and reduce air flow. 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.

3. 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
/ Maintenance Scheduleº.)
NOTICE
Do not drive with the air filter removed, or the efficiency
of air conditioning may be lost.
(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, push 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 mode, which will close off the outside
passage and prevent outside air and dust from entering the
vehicle interior.

STARTING AND DRIVING
163
To allow proper operation of your vehicle's
ventilation system, keep the inlet grilles in front of the
windshield clear of snow, leaves, or other
obstructions.
 If you smell exhaust fumes in the vehicle, drive with
the windows open and the trunk lid closed. Have the
cause immediately located and corrected.BEFORE STARTING THE ENGINE
1. Check the area around the vehicle before entering it.
2. Adjust seat position, seatback angle, head restraint height
and steering wheel angle.
3. Adjust the inside and outside rear view mirrors.
4. Lock all doors.
5. Fasten seat belts.
Remember to check that the service reminder indicators
function when turning the key to ºONº, and check the fuel
gauge to see that you have sufficient fuel.

DRIVING TIPS
193
Depending on where you are driving, we recommend you
carry some emergency equipment.
Some of
the things you might put in the vehicle are tire chains,
window scraper, bag of sand or salt, flares, small shovel,
jumper cables, etc.
TRAILER TOWING
SV32001
Lexus does not recommend towing a trailer with your
vehicle. It is not designed for trailer towing.

IN CASE OF AN EMERGENCY
217
SV04013
2Insert your finger, the screwdriver or equivalent into the
hole to push down the shift lock override button. You can
shift the selector lever while pushing the button.
For your safety, keep the brake pedal depressed.
Be sure to have the system checked by your Lexus dealer as
soon as possible.
IF YOU LOSE YOUR KEYS OR LOCK YOURSELF OUT
You can purchase a new key at your Lexus dealer if you
can give them the key number and master key.
Even if you lose only one key, contact your Lexus dealer to
make a new key. If you lose all your master keys, you cannot
make new keys; the whole engine immobiliser system must be
replaced.
See the suggestion given in ºKeysº on page 8.
You can use the wireless remote control system with the new
key. Contact your Lexus dealer for detailed information.
If your keys are locked in the vehicle and you cannot get a
duplicate, many Lexus dealers can still open the door for you,
using their special tools. If you must break a window to get in,
we suggest breaking the smallest side window because it is the
least expensive to replace. Be extremely cautious to avoid
cuts from the glass.

MAINTENANCE
224
DOES YOUR VEHICLE NEEDREPAIRING?
Be on the alert for changes in performance and sounds, and
visual tip±offs that indicate service is needed. Some important
clues are:

Engine missing, stumbling, or pinging

Appreciable loss of power

Strange engine noises

A fluid leak under the vehicle (however, water dripping from
the air conditioning after use is normal.)

Change in exhaust sound (This may indicate a dangerous
carbon monoxide leak. Drive with the windows open and
have the exhaust system checked immediately.)

Flat±looking tires, excessive tire squeal when cornering,
uneven tire wear

Vehicle pulls to one side when driving straight on a level
road

Strange noises related to suspension movement

Loss of brake effectiveness, spongy feeling brake pedal,
pedal almost touches floors, vehicle pulls to one side when
braking

Engine coolant temperature continually higher than normal
If you notice any of these clues, take your vehicle to your Lexus
dealer as soon as possible. It probably needs adjustment or
repair.
CAUTION
Do not continue driving with the vehicle unchecked. It
could result in serious vehicle damage and possibly
personal injury.
