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 Taking Action on page 7-33.
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 display indicating a quarter or less
remaining fuel has more segments to
show the remaining fuel level in greater
detail.
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 position lights are turned on
with the ignition
switched ON, the
brightness of the dashboard illumination is
dimmed.
(With auto-light control)
When the position 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 position 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 dimmer may cancel after
the brightness is detected.
When the position lights are turned on,
the position lights i ndicator light in the
instrument cluster turns on.
Refer to Headlights on page 4-40.
The brightness of the instrument cluster
and dashboard illuminations can be
adjusted by ro tating the knob.
The brightness decreases by rotating the
knob to the left. A beep sound will be
heard when the knob has been rotated to
the maximum dim position.

WA R N I N G
Always adjust the display brightness and position with the vehicle stopped:
Adjusting the display brightness and position while driving the vehicle is dangerous as doing
so could distract your attention from the road ahead and lead to an accident.
CAUTION
 Do not try to adjust the angle or open/close the active driving display manually.
Fingerprints on the display will make it difficult to view and using excessive force when
operating it could cause damage.
 Do not place objects in the vicinity of the active driving display. The active driving display
may not operate or any interference wi th its operation could cause damage.
 Do not place beverages near the active driving display. If water or other liquids are splashed
on the active driving display, it could cause damage.
 Do not place objects above the active driving display or apply stickers to the dust-proof
sheet/optical receiver as they will cause interference.
 A sensor is integrated to control the display's luminosity. If the optical receiver is covered,
the display's luminosity will lower ma king the display difficult to view.
 Do not allow intense light to hit the optical receiver. Otherwise, it could cause damage.
NOTE
Wearing polarized sunglasses will reduce the visi bility of the active driving display due to
the characteristics of the display.

(Canada)
When the headlight switch is in a position other than
and the ignition is switched ON, the
light sensor senses the surr ounding lightness or darkness and automatically turns the
headlights and other exteri or lights on or off.
CAUTION
Do not shade the light sensor by adhering a st icker or a label on the windshield. Otherwise
the light sensor will not operate correctly.
 The light sensor also works as a rain sensor for the auto-wiper control. Keep hands and
scrapers clear of the windshield when the wiper lever is in the
position and the ignition
is switched ON as fingers could be pinched or the wipers and wiper blades could be
damaged when the wipers activa te automatically. If you are going to clean the windshield,
be sure the wipers are turned off completely when it is partic
ularly tempting to leave the
engine running. This is particularly important when clearing ice and snow.
NOTE
The headlights, other exterior lights and dashboard illumination may not turn off
immediately even if th e surrounding area becomes we ll-lit because the light sensor
determines that it is night time if the surrounding area is continuously dark for several
minutes such as inside long tunnels, traffic ja ms inside tunnels, or in indoor parking lots.
In this case, the lights turn off if the light switch is turned to the
position.
(Without auto headlight off function)
When the headlight switch is in the
position and the ignition is switched to ACC or
the ignition is switched off, the headlights, other exterior lights and dashboard
illumination will turn off.
The dashboard illumination can be adjusted by rotating the knob in the instrument cluster.
Also, the day/night mode can be changed by rotating the knob until a beep sound is heard.
To adjust the brightness of the dashboard illumination:
Refer to Dashboard Illumination on page 4-14.

If the windshield above the rain sensor
is touched or wiped with a cloth.
 If the windshield is struck with a hand
or other object from either outside or
inside the vehicle.
Keep hands and scrapers clear of the
windshield when the wi per lever is in the
AUTO position and the ignition is
switched ON as fingers could be pinched
or the wipers and wiper blades damaged
when the wipers activate automatically.
If you are going to clean the windshield,
be sure the wipers are turned off
completely (when it is most likely that the
engine is left running) this is particularly
important when clearing ice and snow.
NOTE
Switching the auto-wiper lever from the
OFF to the AUTO position while driving
activates the windshield wipers once,
after which they operate according to
the rainfall amount.
The auto-wiper control may not operate
when the rain sensor temperature is
about
－10 °C (14 °F) or lower, or
about 85 °C (185 °F) or higher.
If the windshield is coated with water
repellent, the rain sensor may not be
able to sense the amount of rainfall
correctly and the auto-wiper control
may not operate properly.
If dirt or foreign matter (such as ice or
matter containing salt water) adheres to
the windshield above the rain sensor, or
if the windshield is iced, it could cause
the wipers to move automatically.
However, if the wi pers cannot remove
this ice, dirt or foreign matter, the
auto-wiper control will stop operation.
In this case, set th e wiper lever to the
low speed position or high speed
position for manual operation, or
remove the ice, dirt or foreign matter by
hand to restore the auto-wiper
operation.
If the auto-wiper lever is left in the
AUTO position, the wipers could
operate automatically from the effect of
strong light sources, electromagnetic
waves, or infrared light because the rain
sensor uses an optical sensor. It is
recommended that the auto-wiper lever
be switched to the OFF position other
than when driving the vehicle under
rainy conditions.
(With auto-wiper control)
If the headlight switch and the
windshield wiper switch are in AUTO,
and the wipers are operated at low or
high speed by the auto wiper control for
several seconds, bad weather conditions
are determined and the headlights may
be turned on.
The auto-wiper control functions can be
turned off. Refer to Personalization

i-ACTIVSENSE*
i-ACTIVSENSE is a collective term covering a series of advanced safety and driver support
systems which make use of a Forward Sensing Camera (FSC) and radar sensors. These
systems consist of active safety and pre-crash safety systems.
These systems are designed to assist the driver in safer driving by reducing the load on the
driver and helping to avert collisions or reduce their severity. However, because each system
has its limitations, always drive carefull y and do not rely solely on the systems.
