CAUTIONTo 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 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.
CAUTIONDo 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.
NOTE To protect the engine/transmission
while the select lever is in the “ P ” or
“ N ” position (CVT models) or the shift
lever is in the neutral position (MT
models), the engine is controlled so
that the engine speed may not become
too high even if the accelerator pedal is
depressed hard. & 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 ” /
“ OFF ” or “ ACC ” position, 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.
If you press the trip knob while the ignition
switch is in the “ LOCK ” / “ OFF ” or “ ACC ”
position, the fuel gauge ’ s dial will light up
and the needle will indicate the amount of
fuel remaining in the tank.
If, while the fuel gauge needle is indicating
the amount of fuel remaining in the tank,3-10

you (a) do not press the trip knob for 10
seconds or (b) open and close the driver ’ s
door, the fuel gauge needle will drop to the
“ E ” position and the dial and needle will
turn off.
NOTE
. You will see the “ ” sign in the fuel
gauge.
This indicates that the fuel filler door
(lid) is located on the right side of the
vehicle.
. When you have refueled, the fuel
gauge indicates the amount in the fuel
tank after starting the engine. Also, it
may take some time until the fuel
gauge indication stabilizes.
. The gauge indicates only an approx- imate amount of fuel remaining in the
tank. Use this indication only as a
guide.
. If you refuel while the ignition switch
is in the “ ON ” position, the fuel gauge
may not indicate the correct amount of
the fuel in the fuel tank.
. If the refuel amount is less than
approximately 4.0 US gal (15 liters, 3.3
Imp gal), it may take some time until the
fuel gauge indication stabilizes.
& Temperature gauge
1) Normal operating range
The temperature gauge shows engine
coolant temperature when the ignition
switch is in the “ ON ” position.
The coolant temperature will vary in accordance with the outside temperature
and driving conditions.
We recommend that you drive moderately
until the pointer of the temperature gauge
reaches near the middle of the range.
Engine operation is optimum with the
engine coolant at this temperature range
and high revving operation when the
engine is not warmed up enough should
be avoided.
CAUTIONIf the pointer exceeds the normal
operating range, safely stop the
vehicle as soon as possible.

& ECO gauge
The unit displayed varies depending on the
models.
The ECO gauge shows the difference
between the average rate of fuel con-
sumption since the trip meter was last
reset and the current rate of fuel con-
sumption.
The ECO gauge indicates the current fuel
efficiency as shown in the following chart.

shown until driving 0.6 mile (1 km).
Until that time, the ECO gauge does not
operate.
REV indicator light and buz-
zer (STI)
1) REV indicator light
The REV alarm system has the following
functions.
. When the engine speed reaches the
level that was previously set, the REV
indicator light illuminates to inform you. At
this time, a buzzer also sounds if the
buzzer setting is activated.
. Whenever the engine speed enters the
red zone of the tachometer, the REV
indicator light flashes.
NOTE
Even if the REV alarm system is not set,
the REV indicator light will flash when-3-12
