If this light is on, make sure the parking brake is fully released. The\
light
should go off.
Low brake fluid level warning
If this light comes on and stays on while you are driving, slow down and p\
ull
off the road. Then stop the vehicle carefully. Remember that stopping
distance and pedal effort may be increased. There may be a problem
somewhere in the brake system. Check the fluid level of the see±through
reservoir.
To make sure the parking brake has not caused the warning light to come on\
,
check to see that the parking brake is fully released.

Have the warning system checked by your Lexus dealer.
(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.

The light does not come on as described above.
 The light stays on or flashes.
 The light comes on or starts flashing while driving.
If the light stays on, it indicates that the driver and front passenger air\
bags fail.
If the light flashes, the side airbags and/or seat belt pretensioners fa\
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.

GAUGES, METERS AND SERVICE REMINDER INDICATORS33
(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).

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.

DRIVING TIPS
152
BREAK±IN PERIOD
Drive gently and avoid high speeds.
You need not follow a break±in schedule with your new Lexus. But follow\
ing
a few simple tips for the first 1600 km (1000 miles) can add to the fu\
ture
economy and long life of your vehicle:
Do not drive over 88 km/h (55 mph).
 Avoid overrevving. Maintain engine speed between 2000 and 4000 rpm.
 Avoid full±throttle starts.
 Try to avoid hard stops during the first 300 km (200 miles).
 Do not drive for a long time at any single speed, either fast or slow.
 Do not tow a trailer during the first 800 km (500 miles).
OPERATION IN FOREIGN COUNTRIES
If you plan to drive your Lexus in another country ...
First, comply with the vehicle registration laws.
Second, confirm the availability of the correct fuel (unleaded and minimum
octane rating).
TIPS FOR DRIVING IN VARIOUS CONDITIONS
Always slow down in gusty crosswinds. This will allow you much better
control.
 Drive slowly onto curbs and, if possible, at a right angle. Avoid driving
onto high, sharp±edged objects and other road hazards. Failure to do so can
lead to severe tire damage resulting in tire bursts.
 When parking on a hill, turn the front wheels until they touch the curb so
that the vehicle will not roll. Apply the parking brake, and place the
transmission in ºPº. If necessary, block the wheels.
 Washing your vehicle or driving through deep water may get the brakes
wet. To see whether they are wet, check that there is no traffic near you and
then press the pedal lightly. If you do not feel a normal braking force, the
brakes are probably wet. To dry them, drive the vehicle cautiously while
lightly pressing the brake pedal with the parking brake applied. If they still
do not work safely, pull to the side of the road and call a Lexus dealer for
assistance.

DRIVING TIPS153
CAUTION
Before driving off, make sure the parking brake is fully
released and that the parking brake reminder light is off.
 Do not rest your foot on the brake pedal while driving. It
can cause dangerous overheating, needless wear, and poor
fuel economy.
 To drive down a long or steep hill, reduce your speed and
downshift. Remember, if you ride the brakes excessively,
they may overheat and not work properly. See page 140.
 Be careful when accelerating, upshifting, downshifting or
braking on a slippery surface. The abrupt change in engine
speed, such as sudden acceleration or engine braking, could
cause the vehicle to spin or skid.
 Do not drive in excess of the speed limit. Even if the legal
speed limit permits it, do not drive over 140 km/h (85 mph)
unless your vehicle has high±speed capability tires.
Driving over 140 km/h (85 mph) may result in tire failure,
loss of control and possible injury. Be sure to consult a tire
dealer to determine whether the tires on your vehicle are
high±speed capability tires or not before driving at such
speeds.
 Do not continue normal driving when the brakes are wet. If they are
wet, your vehicle will r equire a longer stopping distance, and it may
pull to one side when the brakes are applied. Also, the parking brake
will not hold the vehicle securely.
WINTER DRIVING TIPS
Make sure you have ethylene±glycol antifreeze in the radiator.
NOTICE
Do not use alcohol type antifreeze.
Check the condition of the battery and cables.
Cold temperatures reduce the capacity of any battery, so it must be in top shape
to provide enough power for winter starting. Page 219 tells you how to
visually inspect the battery. Your Lexus dealer and most service stations will
be pleased to check the battery charge level.
Make sure the engine oil viscosity is suitable for the cold weather.
See page 200 for recommended viscosity. Leaving a heavy summer oil in your
vehicle during winter months may cause harder starting. If you are not sure
about which oil to use, call your Lexus dealer ± they will be pleased to h\
elp.
Check the electronic ignition system for loose connections or obvious
damage.
Keep the door locks from freezing.
Squirt lock de±icer or glycerine into the locks to keep them from fre\
ezing.

DRIVING TIPS
156
Brakes and safety chains
Lexus recommends trailers with brakes that conform to any
applicable federal and state/provincial regulations.
 A safety chain must always be used between the towing vehicle and the
trailer. Leave sufficient slack in the chain for turns. The chain should
cross under the trailer tongue to prevent the tongue from dropping to
the ground in case it becomes damaged or separated. For correct
safety chain procedures, follow the hitch or trailer manufacturer's
recommendations.
CAUTION
 If the total trailer weight exceeds 450 kg (1000 lb.), trailer
brakes are required.
 Never tap into your vehicle's hydraulic system as it will
lower its braking effectiveness.
 Never tow a trailer without using a safety chain securely
attached to both the trailer and the vehicle. If damage
occurs to the coupling unit or hitch ball, there is possible
danger of the trailer wandering over into another lane.
Tires
Ensure that your vehicle's tires are properly inflated. Adjust the tire
pressure to the recommended cold tire pressure indicated below:
Tire pressure, kPa (kgf/cm
2 or bar, psi)
Front 220 (2.2, 32)
Rear 220 (2.2, 32)
 The trailer tires should be inflated to the pressure recommended by the
trailer manufacturer in respect to the total trailer weight.
Trailer lights
Trailer lights must comply with federal, state/provincial and local
regulations. See your local recreational vehicle dealer or rental agency for
the correct type of wiring and relays for your trailer. Check for correct
operation of the turn signals and stop lights e ach time you hitch up. Direct
splicing may damage your vehicle's electrical system and cause a
malfunction of your lights.
Break±in schedule
 Lexus recommends that you do not tow a trailer with a new vehicle or a
vehicle with any new power train component (engine, transmission,
differential, wheel bearing, etc.) for the first 800 km (500 miles) of driving.
Maintenance
If you tow a trailer, your vehicle will require more frequent maintenance
due to the additional load. For this information, please refer to the
scheduled maintenance information in the ºOwner's Manual Supplement/
Maintenance Scheduleº.
 Retighten all fixing bolts of the towing ball and bracket after
approximately 1000 km (600 miles) of trailer driving.
Pre±towing safety check
Check that your vehicle remains level when a loaded or unloaded trailer is
hitched. Do not drive if the vehicle has an abnormal nose±up or
nose±down condition, and check for improper tongue load, overload, worn
suspension or other possible causes.
 Make sure the trailer cargo is securely loaded so that it cannot shift.
 Check that your rear view mirrors conform to any federal, state/provincial
or local regulation. If they do not, install required rear view mirrors\
appropriate for towing purposes.

DRIVING TIPS159
HOW TO SAVE FUEL AND MAKE YOURVEHICLE LAST LONGER
Getting more kilometer/mileage from a liter/gallon of fuel is easy ± just ta\
ke
it easy. It will help make your vehicle last longer, too. Here are some specific
tips on how to save money on both fuel and repairs:
Keep your tires inflated at the correct pressure. Check the pressure
every two weeks, or at least once a month. Underinflation causes tire wear
and wastes fuel.
 Do not carry unneeded weight in your vehicle. Excess weight puts a
heavier load on the engine, causing greater fuel consumption.
 Avoid lengthy warm±up idling. Once the engine is running smoothly,
begin driving ± but gently. Remember, however, that on cold winter days
this may take a little longer.
 Accelerate slowly and smoothly. Avoid jackrabbit starts.
 Avoid long engine idling. If you have a long wait and you are not in traf fic,
it is better to turn off the engine and start again later. 
Avoid engine overrevving. Use a gear position suitable for the road on
which you are traveling.
 Avoid continuous speeding up and slowing down. Stop±and±go driving
wastes fuel.
 Avoid unnecessary stopping and braking. Maintain a steady pace. Try
to time the traffic signals so you only need to stop as little as possible or
take advantage of through streets to avoid traffic lights. Keep a proper
distance from other vehicles to avoid sudden braking. This will also reduce
wear on your brakes.
 Avoid heavy traffic or traffic jams whenever possible.
 Do not rest your foot on the brake pedal. This causes needless wear,
overheating and poor fuel economy.
 Maintain a moderate speed on highways. The faster you drive, the
greater the fuel consumption. By reducing your speed, you will cut down
on fuel consumption.
 Keep the front wheels in proper alignment. Avoid hitting the curb and
slow down on rough roads. Improper alignment not only causes faster tire
wear but also puts an extra load on the engine, which, in turn, wastes fuel.\
 Keep the bottom of your vehicle free from mud, etc. This not only
lessens weight but also helps prevent corrosion.
