GAUGES, METERS AND SERVICE REMINDER INDICATORS
28
FUEL GAUGE
13E001

Low fuel level warning light
The gauge is displayed when the ignition switch is on and indicates the
approximate quantity of fuel remaining in the tank.
It is a good idea to keep the tank over 1/4 full.
This fuel gauge has a non±return type needle which remains at the last
indicated position when the ignition switch is turned off.
If the fuel level approaches ºEº or the low fuel level warning light\
comes on,
fill the fuel tank as soon as possible.
On inclines or curves, due to the movement of fuel in the tank, the fuel g\
auge
needle may fluctuate or the low fuel level warning light may come on earlier
than usual.
If the fuel tank is completely empty, the malfunction indicator lamp comes on.
Fill the fuel tank immediately.
The indicator lamp goes off after driving several times. If the indicator lamp
does not go off, contact your Lexus dealer as soon as possible.

ENGINE COOLANT
TEMPERATURE GAUGE
13E002±1

Normal range
The gauge indicates the engine coolant temperature when the ignition
switch is on. The engine operating temperature will vary with changes in
weather and engine load.
If the needle points to the red zone or higher, stop your vehicle and allow the
engine to cool.

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.

FUEL
Fuel type
Your vehicle must use only unleaded gasoline.
To help prevent gas station mixups, your Lexus has a smaller fuel tank
opening. The special nozzle on pumps with unleaded fuel will fit it, but the
larger nozzle on pumps with leaded gas will not.
At a minimum, the gasoline you use should meet the specifications of ASTM
D4814 in the U.S.A. and CGSB 3.5±M93 in Canada.
NOTICE
Do not use leaded gasoline. Use of leaded gasoline will cause the
three±way catalytic converter/warm up three±way catalytic converter to
lose its effectiveness and the emission control system to function
improperly. Also, this can increase maintenance costs.
Octane rating
Select Octane Rating 87 (Research Octane Number 91) or higher. For
improved vehicle performance, the use of premium unleaded gasoline
with an Octane Rating of 91 (Research Octane Number 96) or higher is
recommended.
Use of unleaded fuel with an Octane Rating or Research Octane Number
lower than stated above will cause persistent heavy knocking. If it is sever\
e,
this will lead to engine damage. If your engine knocks ...
If you detect heavy knocking even when using the recommended fuel, or if\
you hear steady knocking while holding a steady speed on level roads, consu\
lt
your Lexus dealer.
However, now and then, you may notice light knocking for a short time while
accelerating or driving up hills. This is no cause for concern.
Gasolines containing detergent additives
Lexus recommends use of gasolines that contain detergent additives to
avoid build±up of engine deposits.
For further details, ask your Lexus dealer or a local gasoline retailer.
Improved gasolines
The American Automobile Manufacturers Association (AAMA) has
developed a specification of improved gasolines. The AAMA
specification offers optimal fuel information for better vehicle
performance and better protection of your engine.
Lexus recommends the use of gasolines that meet the AAMA specification,
if available, for improved drivability and emission control system.
