■The windshield wiper and washer can be operated when 
The power switch is in ON mode.
■Dripping prevention wiper sweep 
After washing and wiping operation several times, the wipers operate one more time 
after a short delay to prevent dripping. 
However, the last sweep will not happen while the vehicle is moving.
■Effects of vehicle speed on wiper operation
●Intermittent windshield wipers interval  changes when the vehicle is stopped.
●With low speed operation selected, wiper operation will be switched from low speed to intermittent operation only when the vehicle is stationary.
■Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If AUTO mode is selected while the power sw itch is in ON mode, the wipers will oper- ate once to show that AUTO mode is activated.
●If the temperature of the raindrop sensor  is 85°C (185°F) or higher, or -30°C (-22°F) or lower, automatic operation may not occur. In this case, operate the wip-ers in any mode other than AUTO mode.
■When the windshield wipers are in temporary operation 
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 washer fluid in the windshield washer fluid reservoir.
●The raindrop sensor judges the amount of 
raindrops. 
An optical sensor is adopted. It may not oper- ate properly when sunlight from the rising or 
setting of the sun intermittently strikes the windshield, or if bugs etc. are present on thewindshield.
WARNING
■Caution regarding the use of windshield wipers in AUTO mode 
The windshield wipers may operate unexpectedly if the sensor is touched or the wind- shield is subject 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.

closed.
●Confirm the type of fuel.
■Fuel types 
 P. 559
■Fuel tank opening for unleaded gasoline 
To help prevent incorrect fueling, your vehicle has a fuel tank opening that only accom- modates the special nozzle on unleaded fuel pumps.
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 vehicle and before opening the fuel door, touch an unpainted metalsurface to discharge any static electricity. It  is important to discharge static electricity before refueling because sparks resulting fr om 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 discharged 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 vehicle.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  nozzle automatically clicks off.
●Do not top off the fuel tank.
