In  the  situations  shown  below,  the  system  may  not  be  able  to  accurately
detect  surrounding  brightness  levels.  This  may  cause  the  low  beams  to

ahead or other parties. In these cases, manually switch between the high
and low beams.

or fog lights.

• Vehicles ahead have headlights that are either switched off, dirty, are

changing color, or are not aimed properly.

• When driving through an area of intermittently changing brightness and

darkness.

• When frequently and repeatedly driving ascending/descending roads, or

roads with rough, bumpy or uneven surfaces (such as stone-paved
roads, gravel tracks etc.).

WARNING

■

Caution regarding the use of windshield wipers in AUTO mode (vehi-
cles with rain-sensing windshield wipers)

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 fin-
gers, etc. 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 the windshield is dry

Do not use the wipers, as they may damage the windshield.

■

When the washer fluid tank is empty

Do not operate the switch continually as the washer fluid pump may over-
heat.

■

When a nozzle becomes blocked

In this case, contact your Toyota dealer.
Do not try to clear it with a pin or other object. The nozzle will be damaged.

■

To prevent 12-volt battery discharge

Do not leave the wipers on longer than necessary when the hybrid system

Fuel tank opening for unleaded gasoline

To help prevent incorrect fueling, your vehicle has a fuel tank opening that
only accommodates the special nozzle on unleaded fuel pumps.

The fuel tank of your vehicle has a special structure, which
requires a reduction in fuel tank pressure before refueling. After
the opener switch has been pressed, it will take several seconds
until the vehicle is ready for refueling.

Before refueling the vehicle

5-4. Refueling

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 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 of 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.

367

5-4. Refueling

riv

Press the opener to open the
fuel filler door.

The fuel filler door will open within
about  10  seconds  of  the  switch
being  pressed.  Before  refueling  is
possible, a message will be shown
on  the  multi-information  display  in
the  instrument  cluster  to  indicate
the  progress  of  the  fuel  filler  door
opener.

Turn the fuel tank cap slowly to
open and hang it on the back of
the fuel filler door.

NOTICE

■

Refueling

●

Finish refueling within 30 minutes. If more than 30 minutes passes, the
internal valve closes. In this condition, fuel may overflow during the refuel-
ing process.
Press the fuel filler door opener switch again.

●

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.

5-4. Refueling

■

When the fuel filler door cannot be opened by pressing the inside switch

Using the lever to open the fuel filler door may not allow for an adequate
reduction in fuel tank pressure before refueling. To prevent fuel from spilling
out, turn the cap slowly when removing it.
During refueling, fuel may spill out from the filler opening due to air being dis-
charged from inside the fuel tank. Therefore, fill the fuel tank carefully and
slowly.

Open the back door and remove the
cover underneath the luggage compart-
ment light.

Pull the lever backward and check that
the fuel lid opens.

NOTICE

■

When refueling

When  refueling  your  vehicle,  make  sure
that the fuel filler door lock is not pushed
by the fuel nozzle boot, etc., as this may
cause a valve to close, possibly resulting
in a fuel spill.
If  the  fuel  filler  door  lock  has  been
pushed,  operate  the  fuel  filler  door
opener switch in the vehicle before con-
tinuing to refuel.
