GAUGES, METERS AND SERVICE REMINDER INDICATORS
lvi
ENGINE COOLANT
TEMPERATURE GAUGE
 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.
 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 “If your vehicle overheats” on page cccviii.

STARTING AND DRIVING
cclxii
HOW TO START THE ENGINE
Before cranking
1. Apply the parking brake firmly.
2. Turn off unnecessary lights and accessories.
3. Put the selector lever in “P”. If you need to restart the engine
while the vehicle is moving, put the selector lever in “N”. A
starter safety device will prevent the starter from operating if
the selector lever is in any drive position.
4. 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
“Before cranking”.
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 “START”. 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 “If your vehicle will not start” on page ccciii.
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 stalls
frequently, have the engine checked immediately.

STARTING AND DRIVING
cclxv
1Brake pedal 2“D” (Drive) position
2. With your foot holding down the brake pedal, shift the
selector lever to “D”.
Always use the “D” position to improve fuel economy and quiet
driving. Only 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 “D” position. (See “(b) Using engine braking” and\
“(f)
Good driving practice” for exceptions.)
CAUTION
Never put your foot on the accelerator pedal while
shifting.
3. Release the parking brake and brake pedal. Depress
the accelerator pedal slowly for smooth starting.
In normal cruising, the vehicle will start in first gear and
automatically shift up to the most suitable gear. On inclines,
declines or winding roads, etc., the vehicle shifts up and down
automatically according to the running conditions to obtain the
suitable driving power and engine braking.
When the lever is in the “4” position, the automatic
transmission system will select the most suitable gear for the
running conditions such as hill climbing, hard towing, etc.
If you need to accelerate rapidly while driving, depress the
accelerator pedal to the full throttle position. This provides
more acceleration by automatically downshifting the
transmission to the next lower gear or beyond, depending on
the vehicle speed.
If engine braking is needed, such as in descending a long hill,
see “(b) Using engine braking”.

DRIVING TIPS
ccxciv
Avoid jerky starts or sudden acceleration.
 Avoid jerky steering and sharp turns. The trailer could hit
your vehicle in a tight turn. Slow down before making a turn
to avoid the need of sudden braking.
 Remember that when making a turn, the trailer wheels will
be closer than the vehicle wheels to the inside of the turn.
Therefore, compensate for this by making a larger than
normal turning radius with your vehicle.
 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 grade 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 “If your vehicle overheats” on page cccviii.
 Always pl ace wheel blocks under both the vehicle and trailer
wheels when parking. Apply the parking brake firmly. Put
the transmission in “P”. 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 “P” and turn off the engine.
When restarting out after parking on a slope:
1. With the transmission in “P” position, start the engine. Be
sure to keep the brake pedal depressed.
2. Shift into the “3”, “2”, “L” or “R” position.

IN CASE OF AN EMERGENCY
cccviii
IF YOU CANNOT INCREASEENGINE SPEED
If engine speed does not increase when the accelerator pedal
is depressed, there may be a problem somewhere in the
electronic throttle control system.
At this time, vibration may occur. However, if you depress the
accelerator pedal more firmly and slowly, you can drive your
vehicle at low speeds. Have your vehicle checked by your
Lexus dealer as soon as possible.
Even if the abnormality of the electronic throttle control system
is corrected during low speed driving, the system may not be
recovered until the engine is stopped and the ignition key is
turned to the “ACC” or “LOCK” position.
CAUTION
Be especially careful to prevent erroneous pedal
operation.
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 “P” 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.

IN CASE OF AN EMERGENCY
cccix
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?
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
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.
IF YOU HAVE A FLAT TIRE
1. Reduce your speed gradually, keeping a straight
line. Move cautiously off the road to a safe place
— well away from the traffic. Avoid stopping on the
center divider of a highway. Park on a level spot with
firm ground.
2. Stop the engine and turn on your emergency
flashers.
3. F i r m l y s e t t h e p a r k i n g b r a k e a n d p u t t h e
transmission in “P”.
4. Have everyone get out of the vehicle on the side
away from traffic.
5. Read the following instructions thoroughly.
