IMPORTANT INFORMATIONABOUT YOUR LEXUS
Occupant restraint systems
Lexus encourages you and your family to take the time to read
Section 1 −6 of this Owner’s Manual carefully. In terms of
helping you understand how you can receive the maximum
benefit of the occupant restraint systems this vehicle provides,
Section 1 −6 of this Owner’s Manual is the most important
Section for you and your family to read.
Section 1 −6 describes the function and operation concerning
seats, seat belts, SRS airbags and child restraint systems of
this vehicle and some potential hazards you should be aware
of. These systems work together along with the overall
structure of this vehicle in order to provide occupant restraint
in the event of a crash. The effect of each system is enhanced
when it is used properly and together with other systems. No
single occupant restraint system can, by itself, provide you or
your family with the equal level of restraint which these
systems can provide when used together. That is why it is
important for you and your family to understand the purpose
and proper use of each of these systems and how they relate
to each other. The purpose of all occupant
restraint systems is to help reduce
the possibility of death or serious injury in the event of a
collision. None of these systems, either individually or
together, can ensure that there is no injury in the event of
collision. However, the more you know about these systems
and how to use them properly, the greater your chances
become of surviving an acci dent without death or serious
injury.
Seat belts provide the primary restraint to all occupants of the
vehicle, and every occupant of the vehicle should wear seat
belts properly at all times. Children should always be secured
in child restraint systems that are appropriate for their age and
size. SRS (Supplemental Restraint System) airbags are, as
their names imply, designed to work with, and be supplemental
to, seat belts and are not substitutes for them. SRS airbags
can be very effective in reducing the risk of head and chest
injuries by preventing contact of the head and chest with
interior portions of the vehicle.
In order to be effective, the SRS airbags must deploy with
tremendous speed. The rapid deployment of the SRS airbags
makes the SRS airbags themselves potential sources of
serious injury if an occupant is too close to an airbag, or if an
object or some part of his or her body has been placed between
the occupant and the airbag at the time of deployment. This
is just one example of how the instructions in Section 1 −6 of
this Owner’s Manual will help ensure proper use of the
occupant restraint systems, and increase the safety they can
provide to you and your family in the event of an accident.

KEYS AND DOORS
11
Flat key
As a transponder chip is built in its key case, you can start
the engine with this key.
The flat key works in every lock.
A transponder chip for engine immobilizer system has been
placed in the key case of the flat key. This chip is needed to
enable the system to function correctly, so be careful not to lose
this key. If you make your own duplicate key, you will not be
able to cancel the system or start the engine.
Insert your key plate in its key case as shown. We recommend
that you always carry this with you for emergency use. Do not
leave it in your vehicle.
Starting the engine using a flat key
1. Remove the key plate from the key case.
2. Insert the key plate into the ignition switch. The indicator
light keeps flashing.
3. Bring the key case closer to the ignition switch within 10
seconds as indicated by the arrow head. The indicator light
goes out. This means the engine immobilizer system is
automatically canceled. (For details, see “Engine immobilizer
system” on page 14.) You can put the key case away then. You
cannot cancel the engine immobilizer system if 10 seconds
have past after you inserted the key plate. You need to remove
the key plate from the ignition switch and try it again from the
step 2.
4. Start the engine within 20 seconds after the security
indicator light goes out. You cannot start the engine if 20
seconds have past after the security indicator went off. You
need to remove the key plate from the ignition switch and try
it again from the step 2.

KEYS AND DOORS
14
ENGINE IMMOBILIZER SYSTEM
Type A
Type B The engine immobilizer system is a theft prevention
system. When you insert the key in the ignition switch, the
transponder chip in the key’
s head transmits an electronic
code to the vehicle. The engine will start only when the
electronic code in the chip corresponds to the registered
ID code for the vehicle.
The system is automatically set when the key is removed from
the ignition switch. At this time, the security indicator light
flashes. When you insert the key in the ignition switch, the
security indicator light goes out and the system is canceled
automatically, which enables the engine to start.
For your Lexus dealer to make you a new key with built −in
transponder chip, your dealer will need your key number and
master key. However, there is a limit to the number of
additional keys your Lexus dealer can make for you.
If you make your own duplicate key, you will not be able to
cancel the system or start the engine.

KEYS AND DOORS

At this time, two beeps sound and the turn signal lights flash
twice.* Together with the activation of unlocking, the interior
light comes on for 15 seconds if the interior light switch is in
“DOOR” position.** However, this function does not work
when the ignition key is in the “ACC” or “ON” position. For\
further information, see “Illuminated entry system” on page 73.

remote unlock feature.*** If a door is not opened by then, all
the doors will be automatically locked again.

GAUGES, METERS AND SERVICE REMINDER INDICATORS
63
(i) Malfunction Indicator Lamp
This lamp comes on when the ignition key is turned to the
“ON” position and goes off after the engine starts. This
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.
For details, see “Emissions Inspection and Maintenance (I/M)
programs” on page 331.
