ing the switch.
●Compared to turning on the head-
lights, the daytime running light
system offers gr eater durability
and consumes less electricity, so
it can help improve fuel economy.
■Headlight control sensor (if
equipped)
The sensor may not function prop-
erly if an object is placed on the sen-
sor, or anything that blocks the
sensor is affixed to the windshield.
Doing so interferes with the sensor
detecting the level of ambient light
and may cause the automatic head-
light system to malfunction.

dows, and turn the power
switch to OFF.
 Confirm the type of fuel.
■Fuel types
 P.607
■Fuel tank opening for unleaded
gasoline
To help prevent incorrect fueling,
your vehicle has a fuel tank opening
that only accommodates the spe-
cial nozzle on unleaded fuel pumps.
Opening the fuel tank
cap
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

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 sur-
face to discharge any static
electricity. It is important to dis-
charge static electricity before
refueling because sparks result-
ing 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 igni-
tion 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.

remains, wait a few seconds and
then turn the power switch to OFF
once again.
WARNING
■When replacing the fuel tank
cap
Do not use anything but a genu-
ine Toyota fuel tank cap designed
for your vehicle. Doing so may
cause a fire or other incident
which may result in death or seri-
ous injury.
