GAUGES, METERS AND SERVICE REMINDER INDICATORS
lvii
TACHOMETER
The tachometer indicates engine speed in thousands of
rpm (revolutions per minute). Use it while driving to
prevent engine overrevving.
Driving with the engine running too fast causes excessive
engine wear and poor fuel economy. Remember, in most
cases the slower the engine speed, the greater the fuel
economy.
NOTICE
Do not let the indicator needle get into the red zone. This
may cause severe engine damage.
ODOMETER AND TRIP METER
Trip meter reset knob
This meter displays the odometer and two trip meters. To
change the mode indication, push the trip meter reset
knob briefly. Each time you push the knob, the mode
changes in order from the odometer to trip meter A to trip
meter B, then back 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.

lviiiTo set the A
trip meter to zero, display the A meter reading,
push the knob and hold it. The same applies for the B trip
meter.
The data of trip meters will be cancelled if the electrical power
source is disconnected.

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.
(b) Driver’s Seat Belt Reminder Light and Buzzer
The light and buzzer act as a reminder to buckle up the driver’s
seat belt.
Once the ignition key is turned to “ON” or “START”, the
reminder light and buzzer come on if the driver’s seat belt is not
fastened. Unless the driver fastens the belt, the light remains
on and the buzzer stops after about 4 to 8 seconds.
(c) Front Passenger’s Seat Belt Reminder Light
The light acts as a reminder to have the front passenger buckle
up the seat belt.
Once the ignition key is turned to the “ON” position, the
reminder light flashes if a front passenger sits in the front
passenger seat and does not fasten the seat belt.
If luggage or other load is placed on the front passenger seat,
depending on its weight, the reminder light may come on.
(d) SRS Warning Light
This indicator comes on when the ignition key is turned to
the “ON” position. It goes off after about 6 seconds. This
means the SRS airbags and seat belt pretensioners are
operating properly.

lxiiIf any of the following conditions occurs, this indicates a
malfunction of the
airbags or seat belt pretensioners. Contact
your Lexus dealer as soon as possible.
 The light does not come on when the ignition key is turned
to the “ON” position or remains on for more than 6 seconds.
 The light comes on while driving.
The SRS warning light and “AIRBAG OFF” indicator light will
be illuminated if there is a malfunction in the front passenger
occupant classification system.
(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.

(g) Low Engine Oil Level Warning Light
This light warns that the engine oil level is too low. Add oil as
soon as possible. (For instructions, see “Checking the engine
oil level” on page ccclvi.)
While driving on steep inclines or rough roads which causes
the vehicle to substantially sway or on curves, this light may
come on due to the movement of engine oil in the engine.
In normal conditions, due to engine oil consumption, this light
may come on 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
cccliv.)
NOTICE
Continued engine operation with low engine oil will
damage the engine.
(h) Engine Oil Replacement Reminder Light (for vehicles sold in U.S.A.)
This light acts as a reminder to replace the engine oil.
This light will come on when the ignition key is turned to the
“ON” position and will go off after about a few seconds.
When you drive for about 7200 km (4500 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 the “ON” position. If you continue driving
without replacing the engine oil, and if the distance driven
exceeds 8000 km (5000 miles), the light will come on after the
ignition key is turned to the “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 conditions. If the light comes on, replace it as soon as
possible.
The system must be reset after the engine oil replacement.
Reset the system by the following procedure:
1. Turn the ignition key to the “ACC” or “LOCK” position with
the odometer reading shown. (For details, see “Odometer and
trip meter” on page lvii.)
2. Turn the ignition key to the “ON” position while holding down
the trip meter reset knob.
Hold down the knob for at least 5 seconds. The odometer
indicates “000000” and the light goes off.
If the system fails to reset, the light will continue flashing.

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.
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.
