ODOMETER AND TRIP METER
13L145
This meter displays the odometer and two trip meters. To
change the mode indication, push the “ODO/TRIP” button
briefly. Each time you push the button, the mode changes
in order from the odometer to trip meter A to trip meter B,
then to the odometer.
The odometer records the total distance the vehicle has
been driven. The twin trip meter records two different
distances independently.
For example, you can use one meter to calculate the fuel
economy and the other to measure the distance on each trip.
To change the trip meter indication from one trip to the
other, push the “ODO/TRIP” button. To set the trip meter
A to zero, display the meter A reading, then push the
“RESET” button. The same applies for the trip B meter.
The data of trip meters will be cancelled if the electrical power
source is disconnected.

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 Lexus 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 switch is
turned to “ACC” or “LOCK” position.
Emissions inspection and maintenance (I/M) programs
Your vehicle may not pass a state emission inspection if the
malfunction indicator lamp remains on. Contact your Lexus
dealer to check your vehicle’s emission control system and
OBD (On −Board Diagnostics) system before taking your
vehicle for the inspection.
For details, see “Emissions inspection and maintenance (I/M)
programs” on page 431.
(g) Master Warning Light
If any system malfunctions, this warning light comes on or
flashes together with a warning tone, and a warning message
appears in the multi−information display. When the cause of
the problem is eliminated, the warning tone and message on
the display will turn off.
(h) “ABS” Warning Light
The light comes on when the ignition switch 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 anti −lock brake system, the brake
assist system, the traction control system and/or the vehicle
stability control system do/does not operate, but the brake
system still operates conventionally.
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 could lock up during a sudden
braking or braking on slippery road surfaces.

(c) Warning messages
13L148
W40W253
When the engine oil pressure becomes too low, the
master warning light comes on, a warning tone sounds
and the above message appears.
If this message appears 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 message may appear 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 while this warning message is
displayed even for one block. It may ruin the engine.
W41W254
When your brake pads have worn down enough to require
replacement, the master warning light flashes and a
warning tone sounds and the above message appears.
If this message appears while you are driving, have the brake
pads checked and replaced by your Lexus dealer as soon as
possible.
W50W255
When the engine oil level is too low, the master warning
light flashes, a warning tone sounds, and the above
message appears.
Add oil as soon as possible. (For instructions, see “Checking
the engine oil level” on page 452.)
While driving on steep inclines or rough roads which causes
the vehicle to substantially sway or on curves, this message
may appear due to the movement of engine oil in the engine.

GAUGES, METERS AND SERVICE REMINDER INDICATORS
95
In normal conditions, due to engine oil consumption, this
message may a
ppear earlier than the specified service interval
of the scheduled maintenance. This is because the engine oil
is consumed to the low level within the scheduled maintenance
interval and does not indicate a problem. (For detailed
information, see “Facts about engine oil consumption” on page
450.)
NOTICE
Continued engine operation with low engine oil will
damage the engine.
w282
This message indicates that the engine oil maintenance
data has been reset. After replacing the engine oil, be sure
to reset the maintenance data.
To reset the data, perform the following operations:
1. Push the “ODO/TRIP” button to change the display to
blank.
2. Turn the ignition switch off.
3. Turn the ignition switch to “ON” with the trip meter
“RESET” button held down.
4. Keep pushing the “RESET” button for longer than 5
seconds after the ignition is turned on.
