of the windshield to fog up blocking your vision.
When you turn the ignition switch on after the removal and
installation of the battery terminal, the indicator light may flash
and the operating sound of the motor may be heard. This does
not indicate a malfunction.

(d) Replacing the photocatalyst filter for therear seats
This rear air conditioning is equipped with dustproof and
deodorant filter with photocatalyst.
Replace the air filter when the use of rear air conditioning or air
purification function reduces air flow or deodorant
performance.
This filter is an interchangeable type. Do not clean the filter by
washing or air blowing. The use of filter after washing or
cleaning may cause a malfunction of the system. Be sure to
replace it with a new one.
The filter is located in the trunk.
Replace the filter using the following procedures.

3. Pull out the filter case toward you.
4. Replace the filter.
When you install the filter, face the filter surface (gray)
downward and fit the filter folds properly in the case as shown.
5. Install the filter in the reverse order of removal.
The gray surface in the filter may turn to yellow (yellow spots)
because of ultraviolet rays included in the light, however it is
no problem for use.

AIR CONDITIONING
257
When the ignition switch is turned on, the xenon tube comes
on even if the rear air conditioning or rear fan is not operating.
This
does not indicate a malfunction but is required for the long
use of the photocatalyst.
NOTICE
 Do not look into the xenon tube in the air purifier
through the filter slot and do not expose your skin
directly to the light in the xenon tube also. Although
the xenon tube scarcely issues less than 300nm
ultraviolet rays which are thought harmful for the
human body, some people may have symptoms such
as eye sore, vision trouble, skin inflammation, etc.
 Do not disassemble the air purifier , or it may cause a
malfunction. As some part in the purifier is under
high voltage, you may get an electric shock when you
touch it.
 The filters should be installed properly in position.
The use of rear air conditioning controls with the filter
removed may cause the malfunction of the rear air
conditioning controls.
 Turn on the air conditioning with a filter in position.
The activation without an filter may not only cause a
malfunction of the system but also dirty the interior
by spouting dust.

THREEWAY CATALYTICCONVERTERS
31L353a
Threeway catalytic converters are emission control
devices installed in the exhaust system.
The purpose is to reduce pollutants in the exhaust gas.
CAUTION
Keep people and combustible materials away from
the exhaust pipe while the engine is running. The
exhaust gas is very hot.
 Do not drive, idle or park your vehicle over anything
that might burn easily such as grass, leaves, paper or
rags.
NOTICE
A large amount of unburned gases flowing into the
threeway catalytic converter may cause it to overheat
and create a fire hazard. To prevent this and other
damage, observe the following precautions:
 Use only unleaded gasoline.
 Do not drive with an extremely low fuel level; running
out of fuel could cause the engine to misfire, creating
an excessive load on the threeway catalytic
converter.
 Do not allow the engine to run at idle speed for more
than 20 minutes.
 Avoid racing the engine.
 Do not pushstart or pullstart your vehicle.
 Do not turn off the ignition while the vehicle is
moving.
 Keep your engine in good running order.
Malfunctions in the engine electrical system,
electronic ignition system or fuel system could cause
an extremely high threeway catalytic converter
temperature.
 If the engine becomes difficult to start or stalls
frequently, take your vehicle in for a checkup as
soon as possible. Remember, your Lexus dealer
knows your vehicle and its threeway catalytic
converter system best.

STARTING AND DRIVING
298
BEFORE STARTING THE ENGINE
1. Check the area around the vehicle before entering it.
2. Adjust seat cushion length, seat position, seatback angle,
seat cushion angle, seat cushion height, 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 ignition switch to “ON”, and check the
fuel gauge to see that you have sufficient fuel.
SMART IGNITION SWITCH WITH STEERING LOCK
31L345a
Carrying a smart key allows you to start the engine
without the key being inserted into the ignition switch.
The smart key system can be deactivated using a key cancel
switch. For details, see “Deactivating the smart key system”
on page 34.

STARTING AND DRIVING
299
31L346a
When you enter the vehicle carrying a sm art key and push
the ignition switch, the electronic code in the key is
automatically checked as to whether it corresponds to the
registered ID code for the vehicle. The key indicator light
comes on, the steering column lock is released, and the
engine immobilizer system is cancelled.
At this time, the security indicator light goes off and you can
start the engine when you turn the ignition switch and the key
indicator light does not come on. When you turn the ignition
switch, turn it slowly and surely. If you turn it quickly, it may
become stuck. To free it, see the following “If the ignition switch
seems to be stuck”.
If you push the ignition switch when the smart key is not within
the effective range of the smart key system, a warning tone
sounds and “Key is not Detected” appears on the display. If the ignition switch seems to be stuck:
To free the ignition switch, perform the following:
31L638
