the knob to the second clickstop to turn on the headlights
to full intensity for driving at night.
When setting the knob to the third clickstop (“AUTO”), the
headlights will automatically adjust to full intensity and/or turn
on the other lights depending on the darkness of the
surroundings. Likewise, as the surroundings become brighter,
the headlights will turn to reduced intensity, ultimately turning
off the other lights.
NOTICE
To prevent the battery from being discharged, do not
leave the lights on longer than necessary when the
engine is not running.
Automatic headlight leveling system
(vehicles with discharge headlight only)
Vehicle position changes according to loading condition,
passengers getting on and off, vehicle acceleration and
deceleration, etc. However, the headlight beam level is always
maintained automatically by the system at the proper level so
that your headlights do not dazzle other road users.
If this system fails, the warning light in the instrument cluster
comes on. If this occurs, have your vehicle checked by your
Lexus dealer.
If you replace the rear suspension, contact your Lexus dealer
to check the automatic headlight leveling system and headlight
beam level.

(a) Brake System Warning Light and Buzzer
This light comes on in the following cases when the ignition key
is in the “ON” position.
 When the parking brake is applied...
This light comes on for a few seconds when the ignition key is
turned to the “ON” position even after the parking brake is
released.
If the vehicle speed rises above 5 km/h (3 mph) with the parking
brake applied, a buzzer sounds.
 When the brake fluid level is low...
CAUTION
It is dangerous to continue driving normally when the
brake fluid level is low.
Have your vehicle checked at your Lexus dealer in the
following case:
The light does not come on even if the parking brake is
applied when the ignition key is in the “ON” position.
 The light does not come on even if the ignition key is turned
on with the parking brake released. A warning light turning on briefly during operation does not
indicate a problem.
CAUTION
If either of the following conditions occurs, immediately
stop your
vehicle at a safe place and contact your Lexus
dealer.
 The light does not turn off even after the parking
brake is released while the engine is running.
In this case, the brakes may not work properly and
your stopping distance will become longer. Depress
the brake pedal firmly and bring the vehicle to an
immediate stop.
 The brake system warning light remains on together
with the “ABS” warning light.
In this case, not only the antilock brake system will
fail but also the vehicle will become extremely
unstable during braking.

(e) Charging System Warning Light
This warning light comes on when the ignition switch is turned
to the “ON” position, and goes off when the engine is started.
When there are problems in the charging system while the
engine is running, the warning light comes on.
NOTICE
When the charging system warning light comes on
while the engine is running, malfunctions such as the
engine drive belt being broken may have occurred. If
the warning light comes on, immediately stop the
vehicle in a safe place and contact your Lexus dealer.
(f) Low Engine Oil Pressure Warning Light
This light warns that the engine oil pressure is too low.
If it flickers or stays on while you are driving, pull off the road
to a safe place and stop the engine immediately. Call a Lexus
dealer or qualified repair shop for assistance.
The light may occasionally flicker when the engine is idling or
it may come on briefly after a hard stop. There is no cause for
concern if it then goes out when the engine is accelerated
slightly.
The light may come on when the oil level is extremely low. It
is not designed to indicate low oil level, and the oil level must
be checked using the oil level dipstick.
NOTICE
Do not drive the vehicle with the warning light on —
even for one block. It may ruin the engine.

(h) Malfunction Indicator Lamp
This lamp comes on when the ignition key 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 followings.
 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 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.

AIR CONDITIONING
251
If manual switching of air intake is desired —
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 indicator light
will turn off 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 indicator light will
come on.
For normal use, it is best to keep the air intake control button
set to the OUTSIDE AIR mode. If recirculated air is used during
heating, the windows will fog up more easily. To prevent fogging up of the windshield, the air intake mode
may change automatically to the OUTSIDE AIR mode
depending on the condition of the air conditioning system.
For example, when the ambient temperature is low, the air
intake mode may change automatically to the OUTSIDE AIR
mode. This is not a malfunction.
When the air conditioning is ON, 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 onoff of the air conditioning is desired —
Push the “A/C” button to turn the air conditioning on and push
it again to turn the air conditioning off.
The air conditioning does not work if the outside temperature
is lowered down to around 0 C (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 “A/C” button will blink. If the indicator of the
“A/C” button blinks even when the “A/C” button is pushed
again, have the compressor checked by your nearest Lexus
dealer.

STARTING AND DRIVING
402“3” (third range): The most suitable gear is automatically
selected between first and third gears according to vehicle
speed and driving conditions. This range is best used when
stronger engine braking is necessary.
“2” (second range): First or second gear will automatically
be selected according to vehicle speed and driving
conditions. This range is to be used when engine braking
stronger than that of the “3” (third range) position is
necessary.
“1” (first range): This gear is fixed in first regardless of
vehicle
speed or driving conditions. This range is to be used
when maximum engine braking is necessary.
If you attempt to downshift the transmission when it is not
possible to downshift due to high vehicle speed, a warning tone
sounds twice. 
Maximum allowable speeds
To get on a highway or to pass slower traffic, maximum
acceleration may be necessary. Make sure you observe the
following maximum allowable speeds in each range:
range km/h (mph)1 51 (32)
2 92 (58)
3 144 (90)
NOTICE
Do not downshift if you are going faster than the
maximum allowable speed for the next lower range.
 “S” mode indicator light
“S” mode allows you to use the shift range positions.
The “S” mode indicator light comes on when the selector
lever is shifted into the “S” position. When the “S” mode
indicator light does not come on even with the selector lever
moved to the “S” position, there may be a problem
somewhere in the system. Have your vehicle
checked/repaired by your Lexus dealer as soon as possible.
In this case, you can drive in the same condition as in the “D”
position.

(h) Driving in snow mode
Use this mode when starting your vehicle in ice or snow.
To set the snow mode, push the switch. In the “ECT SNOW”
indicator on the instrument cluster is on. To cancel the snow
mode, push the switch again. The “ECT SNOW” indicator light
will go off when the snow mode is cancelled.
If the engine is turned off with the snow mode is on, the snow
mode is cancelled when the engine is restarted.
REAR VIEW MONITOR SYSTEM
The rear view monitor system assists the driver by
displaying an image of the rear of the vehicle while
backing up. The displayed image on the screen is a
horizontally reversed mirror image of the inside rear view
mirror.
To display the rear view image on the screen, place the
selector lever in the “R” position when the ignition switch
is in the “ON” position.
If you move the selector lever out of the “R” position, the screen
returns to the previous screen. Operating another function of
the navigation system will display another screen.
The rear view monitor system is a supplemental device
intended to assist back up. When backing up, be sure to check
behind and all around the vehicle visually.
