■Daytime running light system
●To make your vehicle more visible to other drivers during daytime driving,
the daytime running lights turn on automatically whenever the engine is
started and the parking brake is released with the headlight switch off or in
the “AUTO” position. (Illuminate brighter than the parking lights.) Daytime
running lights are not designed for use at night.
● Compared to turning on the headlights, the daytime running light system
offers greater durability and consumes less electricity, so it can help improve
fuel economy.
■ Headlight control sensor (vehicles with automatic headlight system)
■ Automatic light off system
●When the headlights come on: The headlights and tail lights turn off 30 sec-
onds after a door is opened and closed if the engine switch is turned to the
“ACC” or “LOCK” position. (The lights turn off immediately if the button
on the key is pressed after all the doors are locked.)
● When only the tail lights come on: The tail lights turn off automatically if the
engine switch is tuned to the “ACC” or “LOCK” position and the driver’s door
is opened.
Vehicles with automatic headlight system: If any of the doors is kept open, the
lights automatically turn off after 20 minutes.
To turn the lights on again, turn the engine switch to the “ON” position, or turn
the light switch off once and then back to or .
■ Light reminder buzzer
A buzzer sounds when the key is removed from the engine switch and the
driver’s door is opened while the lights are turned on.
■ Customization that can be configured at Toyota dealer
Settings (automatic light off system) can be changed.
(Customizable features: P. 543)
The sensor may not function properly if an
object is placed on the sensor, 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 headlight sys-
tem to malfunction.
NOTICE
■
To prevent battery discharge
Do not leave the lights on longer than necessary when the engine is not
running.

■The windshield wipers and washer can be operated when
The engine switch is in the “ON” position.
■ 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.
CAUTION
■ 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.

Driving
After refueling, turn the fuel tank
cap until you hear a click. Once
the cap is released, it will turn
slightly in the opposite direction.
■Fuel types
(
P. 520)
■ E85 Fueling Stations (Flex-fuel vehicles)
E85 fueling stations and fuel pumps can be identified by the indication “E85
85% Ethanol”. For more information about fueling stations, please refer to the
U.S. Department of Energy Web site.
http://www.afdc.energy.gov/afdc/locator/stations/
■ Refueling (Flex-fuel vehicles)
Observe the following precautions when switching fuels, in order to maintain
starting and driving performance.
●Do not change fuels when the fuel level is 1/4 or less.
● Always add at least 2.6 gal. (10 L) of fuel.
● After filling up with fuel, warm up the engine or drive the vehicle for at least 5
minutes or 7 miles (11 km).
● Do not accelerate rapidly immediately after refueling.
■ Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, y our vehicle has a fuel tank opening that
only accommodates the special nozzle on unleaded fuel pumps.

2004-4. Refueling
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, 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.
■ When replacing the fuel tank cap
Do not use anything but a genuine Toyota fuel tank cap designed for your
vehicle. Doing so may cause a fire or other incident which may result in
death or serious injury.
