KEYS AND DOORS
19
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.
Locking with power door lock switch
11L007-2

Lock 2
Unlock
To lock all the doors simultaneously, push the power door lock
switch on the front side. Pushing on the rear side will unlock
them.
The same switch is also equipped on the front passenger’s side.
Locking with rear door childprotector
11L009-2
Whenever small children are in the vehicle, lock the rear door so
that it does not open from the inside. To do this, turn the knob
to the ”LOCK” position as shown and then close the door.

ODOMETER AND TRIP METER
13L0041
This meter displays the odometer and two trip meters. To
change the mode indication, push the ”ODO/TRIP” button.
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 A trip meter to zero,
display the A meter reading, then push the ”RESET” button.
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
38If the brake fluid level is correct ...
Have the warning system checked by your Lexus dealer.
(b) Driver’s Seat Belt Reminder Light and Buzzer
Once the ignition key is turned to ”ON” or ”START”, the reminder
light flashes and buzzer sounds if the driver’s seat belt is not
fastened. Unless the driver fastens the belt, the light stays flashing
and the buzzer stops after about 4 to 8 seconds.
(c) Front Passenger’s Seat Belt Reminder Light
Once the ignition key is turned to ”ON” or ”START”, the reminder
light flashes if a passenger sits in the front passenger seat and does
not fasten the seat belt. Unless the front passenger fastens the belt,
the light stays flashing.
If luggage load is placed on the front passenger seat, depending on
its weight and how it is placed on the seat, builtin sensors in the seat
cushion may detect the pressure, causing the reminder light to come
on.
(d) SRS Warning Light
The indicators come on when the ignition key is turned to the
”ACC” or ”ON” position. It goes off after about 6 seconds. This
means the SRS is operating properly.
The SRS warning light system monitors the airbag sensor
assemblies, inflators, seat belt pretensioners, warning light,
interconnecting wiring and power sources.
If either 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.
The light does not come on as described above.
The light stays 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 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.
NOTICE
Do not continue driving if the engine drive belt is broken or
loose.
(f) Malfunction Indicator Lamp
This lamp comes on in the following cases.
a. The fuel tank is completely empty. (See ”Fuel gauge” on page 34
for instructions.)
b. The fuel tank cap is not tightened securely. (See ”Fuel tank cap”
on page 65 for instructions.)
c. There is a problem somewhere in your engine electrical system
or electronic throttle control system.
If it comes on while you are driving in case c., have your vehicle
checked/repaired by your Lexus dealer as soon as possible.
(g) ”ABS” Warning Light
This light warns that there is a problem somewhere in your antilock
brake system.
If the light comes on while you are driving, have your vehicle
checked by your Lexus dealer as soon as possible.
The light will come on when the ignition key is turned to ”ON”, and
will go off after about a few seconds.
When the ”ABS” warning light is on (and the brake system warning
light is off), the brake system operates conventionally but antilock
brake system is not assisting brake performance so that the wheels
could lock up during a sudden brake or braking on slippery road
surfaces.
(h) Open Door Warning Light
This light remains on until all the doors are completely closed.

Adjusting seatback angle
16L112
Move the control switch in the desired direction.
Releasing the switch will stop the seatback in that position.
CAUTION
To reduce the risk of sliding under the lap belt during a
collision, avoid reclining the seatback any more than needed.
The seat belts provide maximum protection in a frontal or rear
collision when the driver and the passenger are sitting up
straight and well back in the seats. If you are reclined, the lap
belt may slide past your hips and apply restraint forces
directly to the abdomen. Therefore, in the event of a frontal
collision, the risk of personal injury may increase with
increasing recline of the seatback.
Adjusting seat cushion angle and height
16L113
Move the control switch in the desired direction.
Releasing the switch will stop the seat cushion in that position.

SEAT BELTS
Seat belt precautions
Lexus strongly urges that the driver and passengers in the vehicle be
properly restrained at all times with the seat belts provided. Failure
to do so could increase the chance of injury and/or the severity of
injury in accidents.
Child. Use a child restraint system appropriate for the child until the
child becomes large enough to properly wear the vehicle’s seat belts.
See ”Child restraint” for details.
If a child is too large for a child restraint system, the child should sit
in the rear seat and must be restrained using the vehicle’s seat belt.
According to accident statistics, the child is safer when properly
restrained in the rear seat than in the front seat.
If a child must sit in the front seat, the seat belts should be worn
properly. Do not let the child sit on your lap. It does not provide
sufficient restraint. If an accident occurs and the seat belts are not
worn properly, the force of the rapid inflation of the airbag may cause
severe injury to the child.
Do not allow the child to stand up or kneel on either rear or front
seats. An unrestrained child could suffer serious injury during
emergency braking or a collision.Pregnant woman. Lexus recommends the use of a seat belt. Ask
your doctor for specific recommendations. The lap belt should be
worn securely and as low as possible over the hips and not on the
waist.
Injured person. Lexus recommends the use of a seat belt.
Depending on the injury, first check with your doctor for specific
recommendations.
CAUTION
Persons should ride in their seats properly wearing their seat
belts whenever the vehicle is moving. Otherwise, they are
much more likely to suffer serious bodily injury in the event
of sudden braking or a collision.
When using the seat belts, observe the following:
Use the belt for only one person at a time. Do not use a
single belt for two or more people even children.
Avoid reclining the seatbacks too much. The seat belts
provide maximum protection when the seatbacks are in the
upright position. (See ”Adjusting seatback angle”.)
Be careful not to damage the belt webbing or hardware.
Take care that they do not get caught or pinched in the seat
or doors.
Inspect the belt system periodically. Check for cuts,
fraying, and loose parts. Damaged parts should be
replaced. Do not disassemble or modify the system.
