GAUGES, METERS AND SERVICE REMINDER INDICATORS

FUEL GAUGE
13X500
Low fuel level warning light
The gauge indicates the approximate quantity of fuel
remaining in the tank when the ignition switch is on.
It is a good idea to keep the tank over 1/4 full.
If the fuel level approaches “E” 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 gauge 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 selection.
ENGINE COOLANT
TEMPERATURE GAUGE
13X501
 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 INDICATORS
49
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 338.
ENGINE OIL PRESSURE GAUGE
13X623
 1
Normal driving 2Idling
The engine oil pressure gauge indicates engine oil
pressure when the ignition is on. Check it while driving to
make sure the needle is in the proper range.
If the engine oil pressure should stay below the normal range,
pull off the road to a safe place and stop the engine
immediately. Call a Lexus dealer or qualified repair shop for
assistance.
Engine oil pressure may not build up when the engine oil level
is too low. The engine oil pressure gauge is not designed to
indicate engine oil level, and the engine oil level must be
checked using the level dipstick.

STARTING AND DRIVING
259
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, turn the ignition key to
“START” position, then release it.
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 334.
NOTICE
 Do not race a cold engine.
 If the engine becomes difficult to start or stalls
frequently, have the engine checked immediately.
AUTOMATIC TRANSMISSION
Your automatic transmission has a shift lock system to
minimize the possibility of incorrect operation. This
means you can only shift out of “P” position when the
brake pedal is depressed with the ignition switch in “ON”
position ( )
31x542

STARTING AND DRIVING
262
31X008e
 1Brake pedal 2“D” (Drive) position
4. 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.
5. 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
315

Always perform a maintenance inspection after each
day of offroad driving that has taken you through
rough terrain, sand, mud, or water. For scheduled
maintenance information, refer to the “Owner’s
Manual Supplement / Scheduled Maintenance”.
WINTER DRIVING TIPS
Make sure you have a proper freeze protection for engine
coolant.
Only use “Toyota Super Long Life Coolant” or similar high
quality ethylene glycol based non −silicate, non −amine,
non− nitrite, and non −borate coolant with long −life hybrid
organic acid technology. (Coolant with long −life hybrid organic
acid technology is a combination of low phosphates and
organic acids.)
See “Checking the engine coolant level” on page 413 for
details of coolant type selection.
For the U.S.A.—“Toyota Super Long Life Coolant” is a mixture
of 50% coolant and 50% deionized water. This coolant
provides protection down to about −35C (− 31F).
For Canada—“Toyota Super Long Life Coolant” is a mixture of
55% coolant and 45% deionized water. This coolant provides
protection down to about −42C (− 44F).
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 pr ovide enough power for winter
starting. Page 450 tells you how to visually inspect the battery.
Your Lexus dealer and most service stations will be pleased to
check the battery charge level.

DRIVING TIPS
326
Because of the added load of the trailer, your vehicle’s
engine may overheat on hot days (at temperatures over
30 C [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 338.
 Always place 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.
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 vehicletrailer 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
frequently. This could cause the brakes to overheat
and result in reduced braking efficiency.
