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.

GAUGES, METERS AND SERVICE REMINDER INDICATORS29
Your vehicle may overheat during severe operating conditions, such as:

Driving up a long hill on a hot day.
 Reducing speed or stopping after high speed driving.
 Idling for a long period with the air conditioning on in stop±and±go traf\
fic.
 Towing a trailer.
NOTICE
Do not remove the thermostat in the engine cooling system as this may
cause the engine to overheat. The thermostat is designed to control the
flow of coolant to keep the temperature of the engine within the
specified operating range.
 Do not continue driving with an overheated engine. See ºIf your
vehicle overheatsº on page 166.
TACHOMETER
13E003
The tachometer indicates engine speed in thousands of rpm (revolutions
per minute). Use it while driving to prevent engine overrevving.
Driving with the engine running too fast causes excessive engine wear and
poor fuel economy. Remember, in most cases the slower the engine speed, the
greater the fuel economy.
NOTICE
Do not let the indicator needle get into the red zone. This may cause
severe engine damage.

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 DRIVING139

1On 2Off
2. Set the overdrive switch to the ON position.
Always set the overdrive switch to the ON position to improve fuel economy
and quiet driving. (See º(b) Using engine brakingº and º(f)\
Good driving
practiceº for exceptions.)
31E008

1 Brake pedal 2ºDº (Drive) position
3. With your foot holding down the brake pedal, shift the selector lever
to ºDº.
CAUTION
Never put your foot on the accelerator pedal while shifting.
4. Release the parking brake and brake pedal. Depress the accelerator
pedal slowly for smooth starting.
The vehicle will start in the first gear and automatically shift to the mos\
t
suitable gear for the running conditions, such as the vehicle speed, hill
climbing, hard towing, etc. However, while the engine coolant temperature
is low and the vehicle is traveling at low speed, the transmission will no\
t shift
into the overdrive gear even with the overdrive switch on.

DRIVING TIPS
158

Crosswinds and rough roads will adversely affect handling of your vehicle
and trailer, causing sway. Pay attention to the rear from time to time to
prepare yourself for being passed by large trucks or buses, which may
cause your vehicle and trailer to sway. If swaying happens, firmly grip the
steering wheel and reduce speed immediately but gradually. Never
increase speed. If it is necessary to reduce speed, brake slowly. Steer
straight ahead. If you make no extreme correction with the steering or
brakes, your vehicle and trailer will stabilize.
 Be careful when passing other vehicles. Passing requires considerable
distance. After passing a vehicle, do not forget the length of your trailer
and be sure you have plenty of room before changing lanes.
 In order to maintain efficient engine braking and electrical charging
performance, do not use overdrive.
 Because of the added load of the trailer, your vehicle's engine may overheat
on hot days (at temperatures over 30C [85 F]) when going up a long or
steep gr ade with a trailer. If the engine coolant temperature gauge indicates
overheating, immediately turn off the air conditioning (if in use), pull your
vehicle off the road and stop in a safe spot. See ºIf your vehicle overheatsº\
on page 166 of this manual.
 Always place wheel blocks under both the vehicle and trailer wheels when
parking. Apply the parking brake firmly. Put the transmission in ºPº.
Avoid parking on a slope with a trailer, but if it cannot be avoided, do so
only after performing the following: 1. Apply the brakes and keep them applied.
2. Have someone place wheel blocks under both the vehicle and trailer
wheels.
3. When the wheel blocks are in place, release your brakes slowly until the
blocks absorb the load.
4. Apply the parking brake firmly.
5. Shift into ºPº and turn off the engine.
When restarting out after parking on a slope:
1. With the transmission in ºPº position, start the engine. Be sure to k\
eep the
brake pedal depressed.
2. Shift into the º2º, ºLº or ºRº position.
3. Release the parking brake and brake pedal and slowly pull or back away
from the wheel blocks. Stop and apply your brakes.
4. Have someone retrieve the blocks.
CAUTION

Do not exceed 72 km/h (45 mph) or the posted towing speed
limit, whichever is lower. Because instability (swaying) of
a towing vehicle±trailer combination usually increases as
the speed increases, exceeding 72 km/h (45 mph) may cause
loss of control.
Slow down and downshift before descending steep or long downhill
grades. Do not make sudden downshifts.
 Avoid holding the brake pedal down too long or too fr equently. This
could cause the brakes to overheat and result in reduced braking
efficiency.

IN CASE OF AN EMERGENCY
166
IF YOUR VEHICLE OVERHEATS
If your engine coolant temperature gauge indicates overheating, if you
experience a loss of power, or if you hear a loud knocking or pinging noise,
the engine has probably overheated.
When the engine overheats
Pull safely off the road, stop the vehicle and turn on your emergency flashers.
Put the transmission in ºPº and apply the parking brake.
A: If steam is coming from your engine:
Turn off the engine. Leave the hood closed until there is no sign of steam or
coolant. Your engine could have been seriously damaged already. Call your
Lexus dealer for assistance.
CAUTION
To help avoid personal injury, keep the hood closed until there
is no steam. Escaping steam or coolant is sign of very high
pressure.
B: If no steam is coming from your engine:
Leave the engine running and turn off the air conditioning. Check the
following.
Is the cooling fan operating?
 Is the coolant in the acceptable range?
 Is the engine drive belt O.K.?
CAUTION
When the engine is running, keep hands and clothing away
from the moving fan and engine drive belt.
 Do not attempt to remove the radiator cap when the engine
and radiator are hot. Serious injury could result from
scalding hot fluid and steam blown out under pressure.
If the cooling fan is not operating or the coolant is not in the acceptabl\
e range,
turn off the engine and call your Lexus dealer.
If both conditions are O.K., after the engine coolant temperature has cooled
to normal, continue driving your vehicle.
If the engine coolant temperature does not cool down, or your vehicle
overheats again, have it checked as soon as possible by your Lexus dealer.
