●If the temperature of the raindrop sensor is 185°F (85°C) or higher, or -22°F

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.

The windshield wipers may operate unexpectedly if the sensor is touched or the
windshield is subject to vibration in AUTO mode. Take care that your fingers or
anything else do not become ca ught 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.

CAUTION
■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
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, pressur-
ized 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.
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 syst em components or the vehicle’s painted
surface.
