(f) “ABS” Warning Light
The light comes on when the ignition key is turned to the “ON”
position. If the anti−lock brake system and the brake assist
system work properly, the light turns off after a few seconds.
Thereafter, if either of the systems malfunctions, the light
comes on again.
When the “ABS” warning light is on (and the brake system
warning light is off), the following systems do not operate, but
the brake system still operates conventionally.
 Anti− lock brake system
 Brake assist system
 Active traction control system
 Vehicle skid control system
 Downhill assist control system
 Hill− start assist control system
When the “ABS” warning light is on (and the brake system
warning light is off), the anti −lock brake system does not
operate, so that the wheels will lock up during a sudden braking
or braking on slippery road surfaces.
If either of the following conditions occurs, this indicates
a malfunction somewhere in the components monitored
by the warning light system. Contact your Lexus dealer as
soon as possible to service the vehicle.
 The light does not come on when the ignition key is turned
to the “ON” position, or remains on.
 The light comes on while you are driving. A warning light turning on briefly during operation does not
indicate a problem.
CAUTION
If the “ABS” warning light remains on together with the
brake system warning light, immediately stop your
vehicle at a safe place and contact your Lexus dealer.
In this case, not only the antilock brake system will fail
but also the vehicle will become extremely unstable
during braking.
Either of the following conditions may occur, but do not
indicate a malfunction:

The light may stay on for about 60 seconds after the ignition
key is turned to the “ON” position. It is normal if it turns off
after a while.
 Depressing the brake pedal repeatedly may turn on the
light. It is normal if it turns off after a few seconds.

(j) “VSC TRAC” Warning Light
The light warns that there is a problem somewhere in the
following.
Vehicle skid control system
 Active traction control system
 Downhill assist control system
 Hill− start assist control system
The light will come on when the ignition key turned to “ON”, and
will go off after a few seconds.
It is not a malfunction that the warning light may stay on for 60
seconds after the ignition key is turned to the “ON” position.
Depressing the brake pedal repeatedly may turn on the lights.
It is normal if they go out after a few seconds.
There is no problem when the “VSC TRAC” warning light
comes on when the brake actuator temperature becomes high.
If the light comes on while driving, the above mentioned
systems do not work. However, as conventional braking
operates when applied, there is no problem to continue your
driving.
In the following cases, contact your Lexus dealer:
 The warning light does not come on after the ignition key is
turned to “ON”.
 The warning light remains on after the ignition key is turned
to “ON”.
 The warning light comes on while driving.
(k) 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.
(l) 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.
(m) Engine Oil Replacement Reminder Light
This light reminds you when to replace the engine oil.
This light will come on when the ignition key is turned to “ON”
and will go off after about a few seconds.
When you drive for about 8000 km (5000 miles) after the
engine oil replacement, this light illuminates for about 3
seconds and then flashes for about 12 seconds with the
ignition key turned to “ON” position. If you continue driving
without the engine oil replacement, and if the driving range
exceeds
12000 km (7500 miles), the light will come on after the
ignition key is turned to “ON” position. The light will remain on
thereafter.
If the light is flashing, we recommend that you replace the
engine oil at an early opportunity depending on the driving and
road condition. If the light comes on, replace it as soon as
possible. You need to reset the light after the engine oil replacement.
Reset the light by following the procedure below:
1. Turn the ignition key to the “OFF” position with the odometer
reading
shown. (For details, see “Odometer and trip meter” on
page 42.)
2. Turn the ignition key to the “ON” position while holding down
the trip meter reset knob.
Hold down the knob until the light goes off. Before the light
goes off, it illuminates for 3 seconds, flashes for 2 seconds and
illuminates for 1 second.
If the system fails to reset, the light will remain flashing. In this
case, return to step 1 and try again.
(n) Low Fuel Level Warning Light
This light comes on when the fuel level in the tank becomes
very low. Fill the tank as soon as possible.
On inclines or curves, due to the movement of fuel in the tank,
the low fuel level warning light may come on earlier than usual.
(o) Low Washer Fluid Warning Light
This light comes on when the fluid level in the tank becomes
very low. Fill the tank as soon as possible.
(p) Key Reminder Buzzer
This buzzer reminds you to remove the key when you open the
driver’s door with the ignition key in the “ACC” or “LOCK”
position.

Altimeter mode
In altimeter mode, the approximate altitude is displayed.
The displayed altitude ranges from −1500 ft. (−500 m) up to
13000 ft. (4000 m).
As the altitude value is converted from the atmospheric
pressure, it can be easily affected by air motion and
temperature, so the indication may vary. The indicated altitude
of a single position may deviate according to the atmospheric
pressure and temperature.
The displayed value is updated every 2 seconds.
RECTIFICATION OF THE ALTITUDE
Rectification is valid only when the correct altitude is known.
While the altitude mode is on the display, push the “
” or “”
button to increase or decrease the altitude by 50 ft. (10 m).
