door lock. You can keep the trunk and glove box
locked when you leave your vehicle and valet key at a
parking facility.

either key. If it banged against your knees while
you were driving, it could turn the ignition switch from the ON position to the ACC or OFF
position, thereby stopping the engine.

Instruments 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.
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.
! ACC
In this position the electrical accessories (radio, ciga-
rette lighter, 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 to the “ON” position.
Do not turn the ignition switch to the “START”position while the engine is running.

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.
To ensure safety, do not attempt to change the
function of the indicator during driving, as an
accident could result.
NOTE
If the connection between the combination meter
and battery is broken for any reason such as vehi-
cle maintenance or fuse replacement, the data re-
corded on the trip meter will be lost. !Tachometer
The tachometer shows the engine speed in thousands
of revolutions per minute.
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 overrevving.
The engine will resume running normally after
the engine speed is reduced below the red
zone.
! Fuel gauge
1) Low fuel warning light
The fuel gauge shows the approximate amount of fuel
remaining in the tank.
When the ignition switch is in the “LOCK” or “ACC” po-
sition, the fuel gauge shows “E” even if the fuel tank

contains fuel.
The gauge may move slightly during braking, turning
or acceleration due to fuel level movement in the tank.
NOTE
You will see the “ ” sign in the fuel gauge
meter.
This indicates that the fuel filler door (lid) is locat-
ed on the right side of the vehicle. !
Low fuel warning light
The low fuel warning light comes on when the tank is
nearly empty [About 2.3 U.S. gal. (9.0 liters, 1.9 Imp.
gal.)]. It only operates when the ignition switch is in the “ON” position.
NOTE
This light does not go out unless the tank is re-
plenished up to an internal fuel quantity of about
4.0 U.S. gal. (15 liters, 3.3 Imp. gal.). !
Temperature gauge
1) Normal operating range
The temperature gauge shows engine coolant temper-
ature when the ignition switch is in the “ON” position.
The coolant temperature will vary in accordance with
