■Dripping prevention wiper
sweep
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 driv-
ing.
■Effects of vehicle speed on
wiper operation
Vehicle speed affects the intermit-
tent wiper interval.
■Raindrop sensor (vehicles with
rain-sensing windshield wipers)
●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
●If the wiper switch i s turned to the
“AUTO” position while the power
switch is in ON, the wipers will
operate once to show that AUTO
mode is activated.
●When the sensor sensitivity ring is
turned toward high while in
“AUTO” position, the wipers will
operate once to indicate that the
sensor sensitivity is enhanced.
●If the temperature of the raindrop
sensor is 185°F (85°C) or higher,
or 5°F (-15°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.

■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

Driving
 Use fluids that are appropriate
to the prevailing outside tem-
peratures.
• Engine oil
• Engine/power control unit coolant
• Washer fluid
Have a service technician
inspect the condition of the
12-volt battery.
 Have the vehicle fitted with
four snow tires or purchase a
set of tire chains for the front
tires.
Ensure that all tires are the same
size and brand, and that chains
match the size of the tires.
Perform the following according
to the driving conditions:
Winter driving tips
Carry out the necessary
preparations and inspec-
tions before driving the
vehicle in winter. Always
drive the vehicle in a man-
ner appropriate to the pre-
vailing weather conditions.
Pre-winter preparations
WA R N I N G
■Driving with snow tires
Observe the following precautions
to reduce the risk of accidents.
Failure to do so m ay result in a
loss of vehicle control and cause
death or serious injury.
●Use tires of the specified size.
●Maintain the recommended
level of air pressure.
●Do not drive in excess of 75
mph (120 km/h), regardless of
the type of snow tires being
used.
●Use snow tires on all, not just
some wheels.
■Driving with tire chains
Observe the following precautions
to reduce the risk of accidents.
Failure to do so may result in the
vehicle being unable to be driven
safely, and may cause death or
serious injury.
●Do not drive in excess of the
speed limit specifi ed for the tire
chains being used, or 30 mph
(50 km/h), whichever is lower.
●Avoid driving on bumpy road
surfaces or over potholes.
●Avoid sudden acceleration,
abrupt steering, sudden brak-
ing and shifting operations that
cause sudden engine braking.
●Slow down sufficiently before
entering a curve to ensure that
vehicle control is maintained.
●Do not use the LTA (Lane Trac-
ing Assist) system.
NOTICE
■Repairing or replacing snow
tires
Request repairs or replacement of
snow tires from Toyota dealers or
legitimate tire retailers.
This is because the removal and
attachment of snow tires affects
the operation of the tire pressure
warning valves and transmitters.
Before driving the vehicle

The engine compartment contains
many mechanisms and fluids that
may move suddenly, become hot,
or become electrically energized.
To avoid death or serious injury,
observe the following precautions.
ItemsParts and tools■When working on the engine
compartment
●Make sure that the “ACCES-
SORY” or “IGNITION ON” on
the multi-information display
and the “READY” indicator are
both off.
●Keep hands, clothing and tools
away from the moving fan and
engine drive belt.
●Be careful not to touch the
engine, power control unit, radi-
ator, exhaust manifold, etc. right
after driving as they may be hot.
Oil and other fluids may also be
hot.
●Do not leave anything that may
burn easily, such as paper and
rags, in the engine compart-
ment.
●Do not smoke, c ause sparks or
expose an open flame to fuel or

electric cooling fa n may automati-
cally start to run if the air condi-
tioning is on and/or the coolant
temperature is high. ( P.414)
■Safety glasses
Wear safety glasses to prevent
flying or falling material, fluid
spray, etc. from getting in your
eyes.
NOTICE
