5-1. Before driving
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When the vehicle is parked
● Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in
the vehicle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and
plastic material of glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the
interior of the vehicle, and may also cause a short circuit in the vehicle’s
electrical components.
● Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a
place such as the glove box or on the floor, it may be lit accidentally when
luggage is loaded or the seat is adjusted, causing a fire.
● Do not attach adhesive discs to the windshield or windows. Do not place con-
tainers such as air fresheners on the instrument panel or dashboard. Adhe-
sive discs or containers may act as lenses, causing a fire in the vehicle.
● Do not leave a door or window open if the curved glass is coated with a
metallized film such as a silver-colored one. Reflected sunlight may cause
the glass to act as a lens, causing a fire.
● Always apply the parking brake, shift the shift position to P, stop the hybrid
system and lock the vehicle.
Do not leave the vehicle unattended while the “READY” indicator is illumi-
nated.
If the vehicle is parked with the shift position in P but the parking brake is
not set, the vehicle may start to move, possibly leading to an accident.
● Do not touch the exhaust pipe while the “READY” indicator is illuminated
or immediately after turning the hybrid system off.
Doing so may cause burns.

Driving
■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 hybrid system
is started and the parking brake is released with the headlight switch in the
/ / position. (Illuminate dimmer than the headlights.) Day-
time running lights are not designed for use at night.
For the U.S.A.: Daytime running lights can be turned off by operating the
headlight switch.
● 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 (if equipped)
■ 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 power switch is turned to
ACCESSORY mode or turned off. (The lights turn off immediately if 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
power switch is turned to ACCESSORY mode or turned off and the driver’s
door is opened.
To turn the lights on again, turn the power switch to ON mode, or turn th\
e light
switch (U.S.A. [type A]), or (U.S.A. [type B]) or
(Canada) once and then back to or . 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.
Air conditioning operation may also be
interrupted.

5-3. Operating the lights and wipers
●In the situations shown below, the system may not be able to accurately
detect surrounding brightness levels. This may cause the low beams to
remain on or the high beams to cause problems for pedestrians, vehicles
ahead or other parties. In these cases, manually switch between the high
and low beams.
• In bad weather (rain, snow, fog, sandstorms etc.)
• The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged.
• The camera sensor is deformed or dirty.
• The camera sensor temperature is extremely high.
• Surrounding brightness levels are equal to those of headlights, tail lights
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 in termittently 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.).
• When frequently and repeatedly taking curves or driving on a winding road.
• There is a highly reflective object ahead of the vehicle, such as a sign or
a mirror.
• The back of a vehicle ahead is highly reflective, such as a container on a truck.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is listing or tilting, due to a flat tire, a trailer being towed etc.
• The high beam and low beam are repeatedly being switched between in an abnormal manner.
• The driver believes that the high beam may be causing problems or dis-
tress to other drivers or pedestrians nearby.

5-3. Operating the lights and wipers
■The windshield wipers and washer can be operated when
The power switch is in ON mode.
■ Dripping prevention wiper sweep (vehicles with rain-sensing windshield
wipers)
After washing and wiping operation several times, the wipers operate one
more time after a short delay to prevent dripping. However, this function will
not operate while driving.
■ Effects of vehicle speed on wiper operation (vehicles with rain-sensing
windshield wipers)
Vehicle speed affects the Intermittent wiper interval.
■ Raindrop sensor (vehicles with ra in-sensing windshield wipers)
● If the wiper switch is turned to the “AUTO” position while the power switch is
in ON mode, the wipers will operate once to show that AUTO mode is acti-
vated.
● If the wiper sensitivity is adjusted to higher, the wiper may operate once to
indicate the change of sensitivity.
● If the temperature of the raindrop sensor is 185 °F (85 °C) or higher, or 14° F
(-10° C) or lower, automatic operation may not occur. In this case, operate
the wipers in any mode other than AUTO mode.
■ If no windshield washer fluid sprays
Check that the washer nozzles are not blocked, if there is washer fluid in the
washer fluid tank.
■ Customization
Settings of AUTO mode operation can be changed.
(Customizable features: →P. 732)
●
The raindrop sensor judges the amount
of raindrops.
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.

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
is off.
