GAUGES, METERS AND SERVICE REMINDER INDICATORS
56If the brake fluid level is correct ...
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 flashes and buzzer comes on if the driver's seat
belt is not fastened. Unless the driver fastens the belt, the light
stays flashing and the buzzer stops after about 4 to 8 seconds.
(c) SRS Airbag Warning Light
This indicator comes on when the ignition key is turned to
the ºACCº or ºONº position. It goes off after about 6
seconds. This means the SRS airbag system is operating
properly.
The SRS airbag warning light system monitors the airbag
sensor assembly, inflators, 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 or remains
on.

The light comes on while driving.
(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.

GAUGES, METERS AND SERVICE REMINDER INDICATORS
57
The light may occasionally flicker when the engine is idling
or it may come on briefly after a hard stop. There is no cause
for concern if it then goes 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 342.)
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 49 for instructions.)
b. The fuel tank cap is not tightened securely (SC400 only).
(See ºFuel tank capº on page 85 for instructions.)
c. There is a problem
somewhere in your engine or automatic
transmission electrical system.
If it comes on while you are driving in case ºc.º, have your
vehicle checked/repaired by your Lexus dealer as soon as
possible.
(h) ºABSº Warning Light
This light warns that there is a problem somewhere in your
anti±lock brake system.
If the light comes on while you are driving, have your vehicle
checked by your Lexus dealer as soon as possible.
The light will come on when the ignition key is turned to
ºONº, and will go off after about a few seconds.
When the ºABSº warning light is on (and the brake system
warning light is off), the brake system operates
conventionally but anti±lock brake system is not assisting
brake performance so that the wheels could lock up during a
sudden brake or braking on slippery road surfaces.

DRIVING TIPS
260

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 234.

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 require 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 a proper freeze protection of engine
coolant.
Your coolant must contain ethylene±glycol type coolant for
a proper corrosion protection of aluminum components. Use
ºToyota Long Life Coolantº or equivalent. See ºChecking
the engine coolant levelº on page 347 for instructions.
NOTICE
Do not use alcohol type antifreeze or plain water alone.
When it is extremely cold, we recommend to use 60%
solution for your Lexus, to provide protection down to about
±50 C (±58F). Do not use more than 70% solution for better
coolant performance.
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 380 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 346 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

HOW TO SAVE FUEL AND
MAKE YOUR VEHICLE LAST LONGER
Getting more kilometer/mileage from a liter/gallon of fuel is
easy ± just take 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 traffic, 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 r est your foot on the clutch or brake pedal. This
causes needless wear, overheating and poor fuel economy.

Maintain a m oderate 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.

Keep your vehicle tuned±up and in top shape. A dirty
air cleaner, improper valve clearance, dirty plugs, dirty oil
and grease, brakes not adjusted, etc. all lower engine
performance and contribute to poor fuel economy. For
longer life of all parts and lower operating costs, keep all
maintenance work on schedule, and if you often drive
under severe conditions, see that your vehicle receives
more frequent maintenance. (For scheduled maintenance
information, please refer to the separate ºOwner's Manual
