Three types of keys are provided for your vehicle:
Master key, submaster key and valet key.
The master key and submaster key fit all
locks on your vehicle. . Ignition switch
. Doors
. Trunk (Sedan)
. Glove box
The valet key fits only the ignition switch
and driver ’s door lock. You can keep the
trunk and glove box locked when you leave your vehicle and valet key at a
parking facility.
CAUTION
Do not attach a large key holder or
key case to either key. If it bangs
against your knees while you are
driving, it could turn the ignition
switch from the ON position to the
Acc or OFF position, thereby stop-
ping the engine.
& Key number plate
The key number is stamped on the key
number plate attached to the key set.
Write down the key number and keep it in
another safe place, not in the vehicle. This
number is needed to make a replacement
key if you lose your key or lock it inside thevehicle.

Immobilizer (Turbo models)
The immobilizer system is designed to
prevent an unauthorized person from
starting the engine. Only keys registered
with your vehicle’s immobilizer system can
be used to operate your vehicle. Even if
an unregistered key fits into the ignition
switch and can be turned to the “START ”
position, the engine will automatically stop
after several seconds.
Each immobilizer key contains a trans-
ponder in which the key ’s ID code is
stored. When a key is inserted into the
ignition switch and turned to the “ON ”
position, the transponder transmits thekey ’s ID code to the immobilizer system ’s
receiver. If the transmitted ID code
matches the ID code registered in the
immobilizer system, the system allows the
engine to be started. Since the ID code is
transmitted and acted upon almost in-
stantly, the immobilizer system does not
impede normal starting of the engine.
If the engine fails to start, pull out the key
once before trying again. (Refer to the“ Ignition switch ”section in chapter 3.)

Ignition switch
WARNING
. Never turn the ignition switch to
“ LOCK ”while the vehicle is
being driven or towed because
that will lock the steering wheel,
preventing steering control. And
when the engine is turned off, it
takes a much greater effort than
usual to steer.
. Before leaving the vehicle, al-
ways remove the key from the
ignition switch for safety and
never allow an unattended child
to remain in the vehicle. Failure
to follow this procedure could
result in injury to a child or
others. Children could operate
the power windows, the moon-
roof or other controls or even
make the vehicle move.
CAUTION
Do not attach a large key holder or
key case to either key. If it banged
against your knees or hands while
you are driving, it could turn the
ignition switch from the “ON ”posi- tion to the
“Acc ”or “LOCK ”posi-
tion, thereby stopping the engine.
Also, if the key is attached to a
keyholder or to a large bunch of
other keys, centrifugal force may act
on it as the vehicle moves, resulting
in unwanted turning of the ignitionswitch.
The ignition switch has four positions:
LOCK, Acc, ON and START. NOTE . Keep the ignition switch in the
“ LOCK ”position when the engine is
not running. . Using electrical accessories for a
long time with the ignition switch in the
"ON" or “Acc ”position can cause the battery to go dead..
If the ignition switch will not move
from the “LOCK ”position to the “Acc ”
position, turn the steering wheel
slightly to the left and right as you turn
the ignition switch. & LOCK
The key can only be inserted or removed
in this position. The ignition switch will lock
the steering wheel when you remove the
key.
If turning the key is difficult, turn the
steering wheel slightly to the right and left
as you turn the key. ! Automatic transmission vehicles
Instruments and controls 3-3
– CONTINUED –

3-4Instruments and controls
The key can be turned from “Acc ”to
“ LOCK ”only when the selector lever is in
the “P ”position.
! Manual transmission vehicles
The key can be turned from “Acc ”to “
LOCK ”only when the key is pushed in
while turning it.
& Acc
In this position the electrical accessories
(radio, accessory power outlet, etc.) can
be used. & ON
This is the normal operating position after
the engine is started. & START
The engine is started in this position. The
starter cranks the engine to start it. When
the key is released (after the engine has
started), the key automatically returns tothe “ON ”position.
CAUTION
Do not turn the ignition switch to the “ START ”position while the engine
is running.
! For vehicle with immobilizer
If your registered key fails to start the
engine, pull out the key once (the security
indicator light will blink), and then insert
the key in the ignition switch and turn it tothe “START ”position and again try to start the engine.
NOTE
The engine may not start in the follow-
ing cases:
. The key grip is touching another key
or a metallic key holder.

&Speedometer
The speedometer shows the vehicle speed. & Odometer/Trip meter
1) Trip meter
2) Odometer
This meter displays the odometer and two
trip meters when the ignition switch is inthe “LOCK ”, “Acc ”or “ON ”position.
If you press the trip knob when the ignition
switch is in the “LOCK ”position, the
odometer/trip meter will light up. It is
possible to switch between the A trip
meter and B trip meter indications while
the odometer/trip meter is lit up. If you do
not press the trip knob within 10 seconds
of illumination of the odometer/trip meter, the odometer/trip meter will go off. !
Odometer
The odometer shows the total distance
that the vehicle has been driven. ! Double trip meter
The trip meter shows the distance that the
vehicle has been driven since you last set
it to zero.
To change the mode indication, briefly
push the knob.
Each press of the knob changes the
function alternately.
To set the trip meter to zero, select the A
trip or B trip meter by pushing the knob
and keep the knob pushed for more than 2 seconds.
CAUTION
To ensure safety, do not attempt to
change the function of the indicator
during driving, as an accident couldresult.
NOTE
If the connection between the combina-
tion meter and battery is broken for any
reason such as vehicle maintenance or
fuse replacement, the data recorded on
the trip meter will be lost. & Tachometer
The tachometer shows the engine speed
in thousands of revolutions per minute.
CAUTION
Do not operate the engine with the
pointer of the tachometer in the red
zone. In this range, fuel injection will
be cut by the engine control module
to protect the engine from overrev-
ving. The engine will resume run-
ning normally after the engine speed
is reduced below the red zone. Instruments and controls
