once. After this, the headlight cleaners will
operate every 5th time the lever is pulled.
■The windshield wiper and washer can be
operated when
The engine switch is in IGNITION ON
mode.
■Dripping prevention wiper sweep
After performing a washing and wiping
operation several times, the wipers operate
one more time after a short delay to prevent
dripping.
However, this final wiper operation will not
be performed while driving.
■Effects of vehicle speed on wiper opera-
tion (vehicles with rain-sensing wind-
shield wipers)
Vehicle speed affects the following even
when the wipers are not in AUTO mode.
●Intermittent wiper interval
●Wiper operation when the washer is
being used (delay until drip prevention
wiper sweep occurs)
With low speed windshield wiper opera-
tion selected, wiper operation will be
switched from low speed to intermittent
wiper operation only when the vehicle is
stationary.
■Raindrop sensor (vehicles with
rain-sensing windshield wipers)
●The raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes the windshield, or if bugs etc. are
present on the windshield.
●If the wiper is turned to AUTO mode
while the engine switch is in IGNITION ON mode, the wipers will operate once
to show that AUTO mode is activated.
●If the temperature of
the raindrop sensor
is 185°F (85°C) or higher, or -22°F
(-30°C) or lower, automatic operation
may not occur. In this case, operate the
wipers in any mode other than AUTO
mode.
■When the windshield wipers are in tem-
porary operation (vehicles with
rain-sensing wind shield wipers)
AUTO mode cannot be activated even if is pressed.
■If no windshield washer fluid sprays
Check that the washer nozzles are not
blocked if there is wash er fluid in the wind-
shield washer fluid reservoir.
WARNING
■Caution regarding the use of wind-
shield wipers in AUTO mode
The windshield wipers may operate
unexpectedly if the se nsor is touched or
the windshield is subj ect to vibration in
AUTO mode. Take care that your fingers
or anything else do not become caught
in the windshield wipers.
■Caution regarding the use of washer
fluid
When it is cold, do not use the washer
fluid until the windshield becomes warm.
The fluid may freeze on the windshield
and cause low visibility. This may lead to
an accident, resulting in death or serious
injury.
NOTICE
■When there is no washer fluid spray
from the nozzle
Damage to the washer fluid pump may
be caused if the lever is pulled toward
you and held continually.

Close both side doors and windows,
and turn the engine switch off.
 Confirm the type of fuel.
■Fuel types
P.337
■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your vehi-
cle has a fuel tank opening that only accom-
modates the special nozzle on unleaded
fuel pumps.
■If the malfunction indicator lamp illumi-
nates
The malfunction indicator lamp may illumi-
nate erroneously if refueling is performed
repeatedly when the fuel tank is nearly full.
Opening the fuel tank cap
Perform the following steps to open
the fuel tank cap:
Before refueling the vehicle
WARNING
■When refueling the vehicle
Observe the following precautions while
refueling the vehicle. Failure to do so may
result in death or serious injury.
●After exiting the ve hicle and before
opening the fuel door, touch an
unpainted metal surface to discharge
any static electricity. It is important to
discharge static electricity before
refueling because sparks resulting
from static electricity can cause fuel
vapors to ignite while refueling.
●Always hold the grips on the fuel tank
cap and turn it slowly to remove it.
A whooshing sound may be heard
when the fuel tank cap is loosened.
Wait until the sound cannot be heard
before fully removing the cap. In hot
weather, pressurized fuel may spray
out the filler neck and cause injury.
●Do not allow anyone that has not dis-
charged static electricity from their
body to come close to an open fuel
tank.
●Do not inhale vaporized fuel.
Fuel contains substances that are
harmful if inhaled.
●Do not smoke while refueling the vehi-
cle.
Doing so may cause the fuel to ignite
and cause a fire.
●Do not return to the vehicle or touch
any person or object that is statically
charged.
This may cause static electricity to
build up, resulting in a possible ignition
hazard.
■When refueling
Observe the following precautions to
prevent fuel overflowing from the fuel
tank:
●Securely insert the fuel nozzle into the
fuel filler neck.
●Stop filling the tank after the fuel noz-
zle automatically clicks off.
●Do not top off the fuel tank.
NOTICE
■Refueling
Do not spill fuel during refueling. Doing
so may damage the vehicle, such as
causing the emission control system to
operate abnormally or damaging fuel
system components or the vehicle’s
painted surface.
