KEYS AND DOORS

KEYS
1Master keys (black) — These keys work in every lock.
For your Lexus dealer to make a new key with a
builtin transponder chip, your dealer will need one
of them.
2Valet key (gray) — This key will not open the glove
box and rear armrest door in the rear seat.
3Key number plate — Keep the plate in a safe place
such as your wallet, not in the vehicle.
A transponder chip for engine immobilizer system has been
placed in the head of the master and valet keys. These chips
are needed to enable the system to function correctly, so be
careful not to lose these keys. If you make your own duplicate
key, you will not be able to cancel the system or start the
engine. To protect items locked in the trunk or glove box when using
valet parking, leave the valet key with the attendant.
The trunk lid can be opened using a loop of wire in the trunk
even with the trunk lid opener main switch in the glove box
turned off.
When keeping items in the trunk, be sure to turn off
the trunk lid opener main switch and lock the glove box and rear
armrest door. To turn off the main switch in the glove box, see
page xcv. For locking the glove box, see page lxxviii. For
locking the rear armrest door, see page lxxxviii.
Since the doors can be locked without a key, you should always
carry the flat key or spare master key in case you accidentally
lock your keys inside the vehicle.
If you should lose your keys or if you need additional keys,
duplicates can be made by a Lexus dealer using the key
number.
We recommend writing down the key number and storing it in
a safe place.

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 xv.) You can put the key case away then. You
cannot cancel the engine immobilizer system if 10 seconds
have past after you ins erted 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.

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.

Setting the system
1. Turn the ignition key to the “LOCK” position and
remove it.
The engine immobilizer system causes the indicator light to
flash.
2. Close and lock all the doors, trunk and hood using an
ignition key or wireless remote control.
If you lock them with wireless remote control, the turn signal
lights flash once.
The flashing indicator light will remain on when all the doors,
trunk and hood are closed and locked.
3. After 30 seconds, the indicator starts flashing and the
system is set.
Cancelling the system
When you unlock any door or trunk using an ignition key
or wireless remote control, the system is cancelled.
If you unlock any door or trunk with wireless remote control, the
turn signal lights flash twice.

STARTING AND DRIVING
cclx
IGNITION SWITCH
“START” — Starter motor on. The key will return to the
“ON” position when released.
For starting tips, see page cclxii.
“ON” — Engine on and all accessories on.
This is the normal driving position.
NOTICE
Do not leave the key in the “ON” position if the engine
is not running. The battery will discharge and the
electronic ignition system could be damaged.
“ACC” — Accessories such as the radio operate, but the
engine is off.If you leave the key in the “ACC” or “LOCK” position and open
the driver’s door, a buzzer will remind you to remove the key.
“LOCK” —
Engine is off and the steering wheel is locked.
The ignition key can be removed only at this position.
To turn the ignition switch from “ACC” to the “LOCK” position,\
you must put the transmission selector lever in the “P” position.
Once you remove the key, the engine immobilizer system is
automatically set. See “Engine immobilizer system” on page
xv.
When starting the engine, the key may seem stuck at the
“LOCK” position. To free it, first be sure the key is pushed all
the way in, and then rock the steering wheel slightly while
turning the key gently.
If, in an emergency, you must turn the engine off while the
vehicle is moving, turn the key only to “ACC”.

IN CASE OF AN EMERGENCY
ccciii
IF YOUR ENGINE STALLS WHILEDRIVING
If your engine stalls while driving...
1. Reduce your speed gradually, keeping a straight line. Move
cautiously off the road to a safe place.
2. Turn on your emergency flashers.
3. Turn the ignition key to “ACC” or “LOCK”, and try starting the
engine again.
If the engine will not start, see “If your vehicle will not start”\
.
CAUTION
If the engine is not running, the power assist for the
brakes and steering will not work, so steering and
braking will be much harder than usual.
IF YOUR VEHICLE WILL NOT START
(a) Simple checks
Before making these checks, make sure you have followed the
correct starting procedure instructions in “How to start the
engine” on page cclxii and that you have sufficient fuel. Since
your vehicle is equipped with the engine immobilizer system,
also check whether the other keys will start the engine. If they
work, your key may be broken. Have the key checked at your
Lexus dealer. If none of your keys work, there may be a
malfunction in the immobilizer system. Call your Lexus dealer.
See “Keys” on page xi.
If the engine is not turning over or is turning over too
slowly —
1. Check that the battery terminals are tight and clean.
2. If the battery terminals are O.K., switch on the interior light.
3. If the light is out, dim or goes out when the starter is cranked,
the battery is discharged. You may try jump starting. See “(c)
Jump starting” for further instruction.
If the light is O.K., but the engine still will not start, it needs
adjustment or repair. Call a Lexus dealer, Roadside
Assistance or Customer Service Assistance. (See
“Foreword”.)

IN CASE OF AN EMERGENCY
cccxxviii
IF YOU LOSE YOUR KEYS ORLOCK YOURSELF OUT
You can purchase a new key at your Lexus dealer if you
can give them the key number and master key, because
your vehicle is equipped with the engine immobilizer
system.
Even if you lose only one key, contact your Lexus dealer to
make a new key. However, if you lose all your master keys, the
dealer cannot duplicate key but only replace the whole system.
See the suggestion given in “Keys” on page xi.
You can use the wireless remote control system with the new
key. Contact your Lexus dealer for detailed information.
If your keys are locked in the vehicle and you cannot get a
duplicate, many Lexus dealers can still open the door for you,
using their special tools. If you must break a window to get in,
we suggest breaking the smallest side window because it is the
least expensive to replace. Be extremely cautious to avoid
cuts from the glass.
