FUEL GAUGE
13L062d
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
13L151
 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.

(e) Discharge Warning Light
This light warns that the battery is being discharged.
If it comes on while you are driving, stop the vehicle, turn off the
engine, and check for the cause. Look first at the engine drive
belt.
 If it is loose or broken, the generator will not charge the
battery properly.
 If the belt is O.K., there is a problem somewhere in the
charging system.
The engine ignition will continue to operate, however, until the
battery is discharged. Turn off the air conditioning, blower,
radio, etc., and drive directly to the nearest Lexus dealer or
repair shop.
NOTICE
Do not continue driving if the engine drive belt is broken
or loose.
(f) Malfunction Indicator Lamp
This lamp comes on when the ignition switch is turned to
the “ON” position and goes off after the engine starts.
This means that the warning light system is operating
properly.
If the lamp remains on, or the lamp comes on while
driving, first check the following:
 Empty fuel tank
If the fuel tank is empty, refuel immediately.
 Loose fuel tank cap
If the fuel tank cap is loose, securely tighten it.
These cases are temporary malfunctions. The malfunction
indicator lamp will go off after taking several driving trips.
If the lamp does not go off even after several trips, contact your
Lexus dealer as soon as possible.
If the fuel tank is not empty or the fuel tank cap is not
loose...
 There is a problem somewhere in the engine, emission
control system, electronic throttle control system, automatic
transmission electrical system or warning light system itself.
Contact your Lexus dealer as soon as possible to service the
vehicle.
If this lamp comes on and engine speed does not increase
when the accelerator pedal is depressed, there may be a
problem somewhere in the electronic throttle control system.

2. To remove the fuel tank cap, turn the cap slowly
counterclockwise, then pause slightly before removing it.
The removed cap can be stored on the back side of the fuel
filler door.
It is not unusual to hear a slight swoosh when the cap is
opened. When installing the cap, turn the cap clockwise until
you hear a click.
If the cap is not tightened securely, the malfunction indicator
lamp comes on. Make sure the cap is tightened securely.
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.
CAUTION
 Make sure the cap is tightened securely to prevent
fuel spillage in case of an accident.
 Use only a genuine Lexus fuel tank cap for
replacement. It is designed to regulate fuel tank
pressure.
NOTICE
To prevent damage to the cap, observe the following
precautions.
Apply force only in the turning direction to the cap.
Do not pull or pry it.
 Do not tighten the cap further after you hear one click
when installing.

DRIVING TIPS
383
CAUTION
Before driving off, make sure the parking brake is
fully released and that the parking brake reminder
light is off.
 Do not leave your vehicle unattended while the
engine is running.
 Do not rest your foot on the brake pedal while driving.
It can cause dangerous overheating, needless wear,
and poor fuel economy.
 To drive down a long or steep hill, reduce your speed
and downshift. Remember, if you ride the brakes
excessively, they may overheat and not work
properly. See page 311.
 Be careful when accelerating, upshifting,
downshifting or braking on a slippery surface. The
abrupt change in engine speed, such as sudden
acceleration or engine braking, could cause the
vehicle to skid or spin.
 Do not drive in excess of the speed limit. Even if the
legal speed limit permits it, do not drive over 140 km/h
(85 mph) unless your vehicle has highspeed
capability tires. Driving over 140 km/h (85 mph) may
result in tire failure, loss of control and possible
injury. Be sure to consult a tire dealer to determine
whether the tires on your vehicle are highspeed
capability tires or not before driving at such speeds.
 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.

DRIVING TIPS
393

Keep your vehicle tunedup and in top shape. A dirty air
cleaner, improper valve clearance, dirty plugs, dirty oil and
grease, brakes not adjusted, etc. all lower engine
performance and contribute to poor fuel economy. For
longer life of all parts and lower operating costs, keep all
maintenance work on schedule, and if you often drive under
severe conditions, see that your vehicle receives more
frequent maintenance. (For scheduled maintenance
information, please refer to the “Owner’s Manual
Supplement / Scheduled Maintenance”.)
CAUTION
Never turn off the engine to coast down hills. Your
power steering and brake booster will not function
without the engine running. Also, the emission control
system operates properly only when the engine is
running.
VEHICLE LOAD LIMITS
Vehicle load limits include total load capacity, seating
capacity, towing capacity and cargo capacity . Follow the
load limits shown below. Total load capacity and seating
capacity are also described on the tire and loading
information label. For location of the tire and loading
information label, see “Checking tire inflation pressure”
on page 468.
Total load capacity: 410 kg (900 lb.)
Total load capacity means combined weight of
occupants, cargo and luggage. Tongue load is included
when trailer towing.
Seating capacity: Total 5 (Front 2, Rear 3)
Seating capacity means the maximum number of
occupants whose estimated average weight is 68 kg
(150 lb.) per person. Depending on the weight of each
person, the seating capacity given may exceed the total
load capacity.
NOTICE
Even if the number of occupants are within the
seating capacity, do not exceed the total load
capacity.

DRIVING TIPS
394
Towing capacity:907 kg (2000 lb.)
Towing capacity means the maximum gross trailer
weight (trailer weight plus its cargo weight) that your
vehicle is able to tow.
Cargo capacity
Cargo capacity may increase or decrease depending on
the size (weight) and the number of occupants. For
details, see “Capacity and distribution” that follows.
CAUTION
Do not apply the load more than each load limit.
That may cause not only damage to the tires, but
also deterioration to the steering ability and
braking ability, which may cause an accident.
CARGO AND LUGGAGE
Stowage precautions
When stowing cargo and luggage in the vehicle,
observe the following:
 Put cargo and luggage in the trunk when at all
possible. Be sure all items are secured in place.
 Be careful to keep the vehicle level. Placing the
weight as far forward as possible helps maintain
vehicle balance.
 For better fuel economy, do not carry unnecessary
weight.
CAUTION
Do not place anything on the package tray
behind the rear seatback. Such items may be
thrown about and possibly injure people in the
vehicle during sudden braking or in an
accident.
 Do not drive with objects left on top of the
instrument panel. They may interfere with the
driver’s field of view. Or they may move during
sharp vehicle acceleration or turning, and
impair the driver’s control of the vehicle. In an
accident they may injure the vehicle occupants.

MAINTENANCE
431
CAUTION
Do not continue driving with the vehicle unchecked. It
could result in serious vehicle damage and possibly
personal injury.
EMISSIONS INSPECTION AND
MAINTENANCE (I/M) PROGRAMS
Some states have vehicle emission inspection programs
which include OBD (On −Board Diagnostics) checks.
The OBD system monitors the operation of the emission
control system. When the OBD system determines that a
problem exists somewhere in the emission control system, the
malfunction indicator lamp comes on. In this case, your vehicle
may not pass the I/M test and need to be repaired. Contact
your Lexus dealer to service the vehicle.
Even if the malfunction indicator lamp does not come on, your
vehicle may not pass the I/M test as readiness codes have not
been set in the OBD system.
Readiness codes are automatically set during ordinary driving.
However, when the battery is disconnected or run down, the
codes are erased. Also, depending on your driving habits, the
codes may not be completely set.
Also, if the malfunction indicator lamp had come on recently
due to temporary malfunction such as a loose fuel tank cap,
your vehicle may not pass the I/M test.
The malfunction indicator lamp will go off after taking several
driving trips, but the error code in the OBD system will not be
cleared unless about 40 trips or more are taken.
If your vehicle does not pass the I/M test and the malfunction
indicator lamp does not come on, contact your Lexus dealer to
prepare the vehicle for re −testing.

ENGINE
449

Take care not to spill gasohol during refueling.
Gasohol may cause paint damage.
Fuel tank capacity
84 L (22.2 gal., 18.5 lmp.gal.)
FUEL PUMP SHUT OFF
SYSTEM323.
The fuel pump shut off system stops supplying fuel to the
engine to minimize the risk of fuel leakage when the engine
stalls or an airbag inflates upon collision. To restart the engine
after the fuel pump shut off system activates, turn the ignition
switch to “ACC” or “LOCK” once and start it.
CAUTION
Inspect the ground under the vehicle before restarting
the engine. If you find that liquid has leaked onto the
ground, it is the fuel system that has been damaged and
it is in need of repair. In this case, do not restart the
engine.
