(b) Seat Belt Reminder Light and Buzzer
Once the ignition key is turned to ºONº or ºSTARTº, the reminder light and
buzzer come on if the driver's seat belt is not fastened. Unless the driver
fastens the belt, the light stays on and the buzzer stops after about 4 to 8
seconds.
(c) SRS Warning Light
The indicator comes on when the ignition key is turned to the ºACCº o\
r
ºONº position. It goes off after about 6 seconds. This means the SRS is
operating properly.
The SRS warning light system monitors the airbag sensor assemblies,
inflators, seat belt pretensioners, warning light, interconnecting wiring and
power sources.
If either of the following conditions occurs, this indicates a malfunction
somewhere in the parts monitored by the warning light system. Contact your
Lexus dealer as soon as possible to service the vehicle.

il.
(d) Discharge Warning Light
This light warns that the battery is being discharged.
If it comes on while you are driving, stop the vehicle, turn off the engine, and
check for the cause. Look first at the engine drive belt.
 If it is loose or broken, the generator will not charge the battery properly.
 If the belt is O.K., there is a problem somewhere in the charging system.
The engine ignition will continue to operate, however, until the battery is
discharged. Turn off the air conditioning, blower, radio, etc., and drive
directly to the nearest Lexus dealer or repair shop.
NOTICE
Do not continue driving if the engine drive belt is broken or loose.

(e) Low Oil Pressure Warning Light
This light warns that the engine oil pressure is too low.
If it flickers or stays on while you are driving, pull off the road to a safe place
and stop the engine immediately. Call a Lexus dealer or qualified repair shop
for assistance.
The light may occasionally flicker when the engine is idling or it may c\
ome
on briefly after a hard stop. There is no cause for concern if it then go\
es out
when the engine is accelerated slightly.
The light may come on when the oil level is extremely low. It is not designed
to indicate low oil level, and the oil level must be checked using the oil\
level
dipstick.
NOTICE
Do not drive the vehicle with the warning light on ± even for one block\
.
It may ruin the engine.
(f) Low Engine Oil Level Warning Light
This light warns that the engine oil level is too low. Add oil as soon as possible.
(For instructions, see ºChecking the engine oil levelº on page 19\
8.)
While driving on steep inclines or rough roads which causes the vehicle to
substantially sway or on curves, this light may come on due to the movement
of engine oil in the engine.
NOTICE
Continued engine operation with low engine oil will damage the engine.
(g) Malfunction Indicator Lamp
This lamp comes on in the following cases.
a. The fuel tank is completely empty. (See ºFuel gaugeº on page 28 for
instructions.)
b. The fuel tank cap is not tightened securely. (See ºFuel tank capº on page
52 for instructions.)

AIR CONDITIONING AND AUDIO
108
20E007±1
The air intake control button is used to switch the air intake between the
OUTSIDE AIR mode and RECIRCULATED AIR mode.
With the button 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 OUT\
SIDE
AIR mode. If recirculated air is used during heating, the windows will \
fog up
more easily.If the engine coolant temperature becomes extremely high, the
RECIRCULATED AIR mode is automatically selected. This is not a
malfunction. When the engine coolant temperature is lowered, the previous
mode resumes.
If manual on±off of the air conditioning is desired ±
Push the ºA/Cº button to turn the air conditioning on and push it agai\
n to turn
the air conditioning off.
The air conditioning does not work if the outside temperature is lowered do\
wn
to around 0C (32F).
If the system is used for ventilation, heating in dry weather or removing \
frost
or exterior fog on the windshield, turn the air conditioning off once it is no
longer required. This will improve fuel economy. The air conditioning can
be used for year±round automatic temperature control including cooling \
and
dehumidifying operation.
If the air conditioning compressor does not operate, the indicator of the \
ºA/Cº
button will blink. If the indicator of the ºA/Cº button blinks even wh\
en the
ºA/Cº button is pushed again, have the compressor checked by your \
nearest
Lexus dealer.
Displaying the outside temperature ±
When you push the ºOUTSIDE TEMPº knob, the temperature display shows
the outside temperature. To return to the display of the current set
temperature, push the knob again. The temperature display ranges from
±30 C (±22F) up to 50C (122F).

STARTING AND DRIVING133

Keep your engine in good running order. Malfunctions in the engine
electrical system, electronic ignition system/distributor ignition
system or fuel system could cause an extremely high three±way
catalytic converter/warm up three±way catalytic converter
temperature.
 If the engine becomes difficult to start or stalls frequently, take your
vehicle in for a check±up as soon as possible. Remember, your Lexus
dealer knows your vehicle and its three±way catalytic converter/warm
up three±way catalytic converter system best.
 To ensure that the three±way catalytic converter /warm up three±way
catalytic converter and the entire emission control system operate
properly, your vehicle must receive the periodic inspections required
by the Lexus Maintenance Schedule. For scheduled maintenance
information, refer to the separate ºOwner's Manual Supplement/
Maintenance Scheduleº.
ENGINE EXHAUST CAUTION
CAUTION
Avoid inhaling the engine exhaust. It contains carbon
monoxide, which is a colorless and odorless gas. It can
cause unconsciousness or even death.
 Make sure the exhaust system has no holes or loose
connections. The system should be checked from time to
time. If you hit something, or notice a change in the sound
of the exhaust, have the system checked immediately.
 Do not run the engine in a garage or enclosed area except
for the time needed to drive the vehicle in or out. The
exhaust gases cannot escape, making this a particularly
dangerous situation.
 Do not remain for a long time in a parked vehicle with the
engine running. If it is unavoidable, however, do so only in
an unconfined area and adjust the heating or cooling
system to force outside air into the vehicle.
 Keep the trunk lid closed while driving. An open or
unsealed trunk lid may cause exhaust gases to be drawn
into the vehicle. If you must drive with the trunk lid open
to accommodate a large object, close the windows, open all
the dashboard vents and have the heating or cooling system
deliver fresh air into the vehicle by turning the fan to high
speed with the air intake control button in the OUTSIDE
AIR mode.

STARTING AND DRIVING
134
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 inside and outside rear view mirrors.
4. Lock all doors.

HOW TO START THE ENGINE
Before cranking
1. Apply the parking brake firmly.
2. Turn off unnecessary lights and accessories.
3. Put the selector lever in ºPº. If you need to restart the engine \
while the
vehicle is moving, put the selector lever in ºNº. A starter safety devic\
e will
prevent the starter from operating if the selector lever is in any drive positi\
on.
4. Depress the brake pedal and hold it to the floor until you are ready to \
drive
off.
Starting the engine
Before starting the engine, be sure to follow the instructions in ºBefore
crankingº.
Normal starting procedure
The multiport fuel injection system/sequential multiport fuel injection sys\
tem
in your engine automatically controls the proper air±fuel mixture for s\
tarting.
You can start a cold or hot engine as follows:
1. With your foot off the accelerator pedal, crank the engine by turning the
key to ºSTARTº. Release it when the engine starts.
2. After the engine runs for about 10 seconds, you are ready to drive.If the weather is below freezing, let the engine warm up for a few minut\
es
before driving. Do not leave the vehicle while the engine is warming up.
If the engine stalls ...
Simply restart it , using the correct procedure given in normal starting\
.
If the engine will not start
See ºIf your vehicle will not startº on page 162.
NOTICE

Do not crank for more than 30 seconds at a time. This may overheat
the starter and wiring systems.
 Do not race a cold engine.
 If the engine becomes difficult to start or stalls frequently, have the
engine checked immediately.

STARTING AND DRIVING

BRAKE SYSTEM
The tandem master cylinder brake system is a hydraulic system with two
separate sub±systems. If either sub±system should fail, the other will still
work. However, the pedal will be harder to press, and your stopping distance
will be longer. Also, the brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a single brake system.
Have your brakes fixed immediately.
Brake booster
The brake booster uses engine vacuum to power±assist the brakes. If the
engine should quit while you are driving, you can bring the vehicle to a stop
with normal pedal pressure. There is enough reserve vacuum for one or t\
wo
stops but no more!
CAUTION
Do not pump the brake pedal if the engine stalls. Each push
on the pedal uses up your vacuum reserve.
 Even if the power assist is completely lost, the brakes will
still work. But you will have to push the pedal hard ± much
harder than normal. And your braking distance will be
longer.
Anti±lock brake system
The anti±lock brake system is designed to automatically help prevent
lock±up of the wheels during a sudden brake or braking on slippery road
surfaces. This assists in providing directional stability and steering
performance of the vehicle under these circumstances.
The anti±lock brake system becomes operative after the vehicle has
accelerated to a speed in excess of approximately 10 km/h (6 mph). It stops
operating when the vehicle decelerates to a speed below approximately 5
km/h (3 mph).
You may hear a sound in the engine compartment for a few seconds when the
engine is started or just after the vehicle is started. This means that the
anti±lock brake system is in the self±check mode, and does not indicate a
malfunction.
Effective way to press the ABS brake pedal: When the anti±lock brake
system function is in action, you may feel the brake pedal pulsating and hear
a noise. In this situation, to let the anti±lock brake system work f\
or you, just
hold the brake pedal down more firmly. Do not pump the brake. This will
result in reduced braking performance.
The brake pedal pulsation caused by the anti±lock brake system may indic\
ate
hazardous road surface conditions. Although the anti±lock brake system
assists in providing vehicle control, it is still important to drive with all due
care, because the anti±lock brake system cannot overcome the laws of physic\
s
that act on your vehicle:
 Braking capability is dependent on tire friction with the road surface.
