KEYS AND DOORS
23
Locking with inside lock button
 1Lock 2Unlock
Push in the lock button to lock and unlock the door.
The front doors can be opened by pulling the inside handles
even if the lock buttons are in the locked position.
CAUTION
Do not pull the inside handle of the front doors while
driving. The doors will open and an accident may occur.
Lexus strongly recommends that all children be placed
in the rear seat of the vehicle.
Closing the door with the lock button pushed in will also lock
the door. Be careful not to lock your keys in the vehicle. Doors
cannot be locked when either front door is open and the key is
in the ignition.
If the vehicle is subjected to a severe frontal, rear or side
impact with the ignition switch turned to the “ON” position, all
doors will unlock automatically after a few seconds.
CAUTION
Before driving, make sure the doors are closed and
locked, especially when small children are in the
vehicle. Along with the proper use of seat belts, locking
the doors helps prevent the driver and passengers from
being thrown out from the vehicle during an accident.
It also helps prevent the doors from being opened
unintentionally.

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.
To 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.

GAUGES, METERS AND SERVICE REMINDER INDICATORS

(a) Brake System Warning Light
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.
 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 cases.
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.
(b) Driver’s Seat Belt Reminder Light and
Buzzer
This light and buzzer remind you 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 stays on
and the buzzer stops after about 4 to 8 seconds.

GAUGES, METERS AND SERVICE REMINDER INDICATORS

(c) Front Passenger’s Seat Belt ReminderLight
This light reminds you to buckle up the front passenger’s seat
belt.
Once the ignition key is tur ned 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. Unless the
front passenger fastens the belt, the light keeps flashing.
If luggage load is placed on the front passenger seat,
depending on its weight and how it is placed on the seat,
built−in sensors in the seat cushion may detect the pressure,
causing the reminder light to come on.
(d) SRS Warning Light
This light 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.
This warning light system monitors the airbag sensor
assembly, front airbag sensors, side and curtain shield airbag
sensor assemblies, curtain shield airbag sensor assemblies,
driver’s seat position sensor, driver’s seat belt buckle switch,
front seat belt pretensioner assemblies, inflators, warning light,
interconnecting wiring and power sources. If any of the following conditions occurs, this indicates a
malfunction
somewhere in the parts monitored by the warning
light system. Contact your Lexus dealer as soon as possible
to service the vehicle.
 When the ignition switch is turned to the “ON” position, the
light does not come on, remains on or flashes.
 The light comes on or starts flashing while driving.
If the light stays on, it indicates that the driver and front
passenger airbags fail. If the light flashes, the side and curtain
shield airbags and/or seat belt pretensioners fail.
(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.
