ENGINE COOLANT TEMPERATUREGAUGE
SV13012

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.
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 traffic.
NOTICE
Do not remove the thermostat in the engine cooling
system as this may cause the engine to overheat. Thethermostat is designed to control the flow of coolantto keep the temperature of the engine within thespecified operating range.
Do not continue driving with an overheated engine.See ºIf your vehicle overheatsº on page 285.

STARTING AND DRIVING
237
HOW TO START THE ENGINE
Before cranking
1. Apply the parking brake firmly.
2. Turn off unnecessary lights and accessories.
3.Manual transmission : Press the clutch pedal to the floor
and shift the transmission into neutral. Hold the clutch pedal
to the floor until the engine is started. A starter safety device
will prevent the starter from operating if the clutch pedal is not
fully depressed.
Automatic transmission : 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 device will prevent the
starter from operating if the selector lever is in any drive
position.
4. For automatic transmission only :Depress the brake
pedal and hold it to the floor until driving 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 system in your engine automatically controls the
proper air-fuel mixture for starting. You can start a cold or hot
engine as follows:
With your foot off the accelerator pedal, crank the engine by
turning the key to ºSTARTº. Release it when the engine starts. Engine should be warmed up by driving, not in idle. For
warming up drive with smoothly turning engine until engine
coolant temperature is within normal range.
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 281.
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 stallsfrequently, have the engine checked immediately.

SS31019

1Power position 2Normal position
3Snow position
2. Set the driving pattern selector switch to the ºNormalº
position.
Your transmission has a driving pattern selector switch which
allows you to select ºPowerº, ºNormalº or ºSnowº mode \
to suit
your driving condition. For ordinary driving, Lexus
recommends that you use the ºNormalº position to improve fuel
economy.
3. For more powerful acceleration and sporty driving, use
the ºPowerº position.
In the ºPowerº position, the ºECT PWRº light in the instrument\
cluster is on and the transmission is shifted up at higher vehicle
speeds and shifted down more responsively than in the
ºNormalº position.
For ºSnowº mode, see ºElectronic Throttle Control
Systemº on page 260.
SV31022

1Brake pedal 2ºDº (Drive) position
4. With your foot holding down the brake pedal, shift the
selector lever to ºDº.
Always use the ºDº position to improve fuel economy and quiet
driving. In this position, shifting into the overdrive gear is
possible. However, while the engine coolant temperature is
low, the transmission will not shift into the overdrive gear even
in the ºDº position. (See º(c) Using engine brakingº and\
º(g)
Good driving practiceº for exceptions.)
CAUTION
Never put your foot on the accelerator pedal while
shifting.

DRIVING TIPS
270
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 your coolant is properly protected against
freezing.
Only use ºToyota Super Long Life Coolantº or similar high
quality ethylene glycol based non-silicate, non-amine,
non-nitrite, and non-borate coolant with long-life hybrid
organic acid technology.
See ºChecking the engine coolant levelº on page 337 for
details of coolant type selection.
ºToyota Super Long Life Coolantº is pre-mixed with 50%
coolant and 50% deionized water. This coolant provides
protection down to about -35 C (-31F).
NOTICE
Do not use plain water alone.
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 378 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.

IN CASE OF AN EMERGENCY
285
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 (automatic)
or neutral (manual) 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 eng ine 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
acceptable 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.
