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.
See the inner back cover for fuel capacity and recommended fuel selectio\
n.
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.

CHECKING THE ENGINE COOLANT LEVEL
62E004±3
1Reservoir cap 2Upper line 3Lower line
Park the vehicle at a level spot and look at the see±through coolant
reservoir when the engine is cool. The coolant level is satisfactory if it is
between the upper and lower lines on the tank. If the level is low, add
ethylene±glycol type coolant.
The coolant level in the reservoir will vary with engine coolant temperatur\
e.
However, if the level is on or below the lower line, add coolant to bring the
level up to the upper line.
Use only ethylene±glycol type coolant. For information on ethylene±g\
lycol
coolant, see also ºEngine coolant selectionº described below.
If the coolant level drops within a short time after replenishing, there\
may be
a leak in the system. Visually check the radiator, hoses, radiator cap, drain
cock and water pump. If you can find no leak, have your Lexus dealer test the cap pressure and \
check
for leaks in the cooling system.
CAUTION
To prevent burning yourself, do not remove the radiator cap
when the engine is hot.
Engine coolant selection
Your coolant must contain ethylene±glycol antifreeze. In addition to
preventing freezing and subsequent damage to the engine, this will also
prevent corrosion. Further supplemental inhibitors or additives are neither
needed nor recommended.
Read
the antifreeze container for information on freeze protection. Follow t\
he
manufacturer 's directions for how much to mix with water. The total capacity
of the cooling system is given on page 193. We recommend 50% solution be
used for your Lexus, or a sufficient quantity to provide protection to about
±35 C (±31F).
NOTICE
Do not use alcohol type antifreeze or plain water alone.
