WARNING
Do not stop the engine while the
vehicle is moving:
Stopping the engine while the vehicle
is moving for any reason other than in
an emergency is dangerous. Stopping
the engine while the vehicle is moving
will result in reduced braking ability
due to the loss of power braking ,
which could cause an accident and
serious injury.
1. Stop the vehicle completely.
2.(Manual transmission)
Shift into neutral and set the
parking brake.
(Automatic transmission)
Shift the selector lever to the P

minutes after the ignition is switched
from ON to OFF, whether or not the
A/C is on or off, to cool the engine
compartment quickly.
If the system detects that the
remaining battery power of the key is
low when the ignition is switched
from ON to ACC or OFF, the
following is indicated.
Replace with a new battery before
the key becomes unusable.
Refer to Key Battery Replacement on
page 6-29.
A message is indicated in the display

CAUTION
When the engine coolant temperature
gauge needle is in the red range, the
engine coolant temperature is
extremely high. Drive slowly to reduce
engine load. If the engine coolant
temperature gauge needle is in the red
range, there is the possibility of
overheating. Park the vehicle in a safe
place immediately and take
appropriate measures.
Refer to Overheating on page 7-17.
NOTE
If the engine or engine coolant
temperature is high or low, the
engine output may be restricted to
protect the engine.
▼Fuel Gauge
The fuel gauge shows approximately
how much fuel is remaining in the tank
when the ignition is switched ON. We
recommend keeping the tank over 1/4
full.

1. Full
2. 1/4 Full
3. Empty

If the low fuel warning light illuminates
or the fuel level is very low, refuel as
soon as possible.
If inconsistency in engine performance
or stalling occurs due to low fuel level
conditions, refuel the vehicle as soon
as possible and add at least 10 L (2.7
US gal, 2.2 Imp gal) of fuel.
Refer to Low Fuel Warning Indication/
Warning Light on page 7-30.

NOTE
After refueling, it may require some
time for the indicator to stabilize. In
addition, the indicator may deviate
while driving on a slope or curve
since the fuel moves in the tank.
The direction of the arrow ()
indicates that the fuel-filler lid is on
the left side of the vehicle.
▼ Dashboard Illumination
(Without auto-light control)
When the lights are turned on with the
ignition switched ON, the brightness of
the dashboard illumination is dimmed.
(With auto-light control)
When the lights are turned on with the
ignition switched ON, the brightness of
the dashboard illumination is dimmed.
However, when the light sensor
detects that the surrounding area is
bright such as when the lights are
turned on in the daytime, the
dashboard illumination does not dim.
NOTE
(With auto-light control)
When the ignition is switched ON in
the early evening or at dusk, the
dashboard illumination is dimmed
for several seconds until the light
sensor detects the brightness of the
surrounding area, however, the
dimming may cancel after the
brightness is detected.
When the lights are turned on, the
lights-on indicator light in the
instrument cluster turns on.
Refer to Headlights on page 4-44.
The brightness of the instrument panel
and dashboard illuminations can be
adjusted by pressing the dashboard
illumination switch while the
dashboard illumination is dimmed.
The brightness increases by pressing
the + switch.
The brightness decreases by pressing
the - switch. If you press the - switch
while the instrument cluster is at
maximum dimness, a sound is
activated to notify you that the
current dimmer setting is at
maximum dimness.

1. Bright
2. Dim
Function for canceling illumination
dimmer
The illumination dimmer can be
canceled by pressing the + switch
while the instrument cluster is at
maximum dimness and while the
ignition is switched ON. If you press
the + switch again while the
illumination dimmer is canceled, a

▼ Distance-to-empty
This displays the approximate distance
you can travel on the remaining fuel
based on the fuel economy.
The distance-to-empty will be
calculated and displayed every second.

NOTE
Even though the distance-to-empty
display may indicate a sufficient
amount of remaining driving distance
before refueling is required, refuel as
soon as possible if the fuel level is
very low or the low fuel warning light
illuminates.
The display will not change unless
you add more than approximately 9
L (2.3 US gal, 1.9 Imp gal) of fuel.
The distance-to-empty is the
approximate remaining distance the
vehicle can be driven until all the
graduation marks in the fuel gauge
indicating the remaining fuel supply
disappear.
If there is no past fuel economy
information such as after first
purchasing your vehicle or the
information is deleted when the
battery cables are disconnected, the
actual distance-to empty/range may
differ from the amount indicated.
