shield wipers
With low speed windshield wiper
operation selected, wiper operation
will be switched from low speed to
intermittent wiper operation when
the vehicle is stationary. (However,
when the sensor s ensitivity is
adjusted to the highest level, the
mode will not switch.)
■Raindrop sensor (vehicles with
rain-sensing windshield wipers)
●The raindrop sensor judges the
amount of raindrops.
●If the wiper switch is turned to the
“AUTO” position while the power
switch is in ON, the wipers will
operate once to show that “AUTO”
mode is activated.
●If the wiper sensitivity is adjusted
to higher, the wip er may operate
once to indicate the change of
sensitivity.
●If the temperature of the raindrop
sensor is 185°F (85°C) or higher,
or 5°F (-15°C) or lower, the auto-
matic operation m ay not occur. In
this case, operate the wipers in
any mode other than “AUTO”.
■If no windshield washer fluid
sprays
Check that the wash er nozzles are
not blocked if there is washer fluid in

WARNING
■Caution regarding the use of
windshield wipe rs in “AUTO”
mode (vehicles with rain-
sensing windshield wipers)
The windshield wipers may oper-
ate unexpectedly if the sensor is
touched or the windshield is sub-
ject to vibration in “AUTO” mode.
Take care that your fingers or
anything else does not become
caught in the windshield wipers.
■Caution regarding the use of
washer fluid
When it is cold, do not use the
washer fluid unt il the windshield

3784-6. Driving tips
Use fluids that are appropriate
to the prevailing outside tem-
peratures.
• Engine oil
• Engine coolant
• 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.
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
WARNING
■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 LTA (Lane Tracing
Assist) system.
NOTICE
■Repairing or replacing snow
tires (vehicles with tire pres-
sure warning system)
Request repairs or replacement of
snow tires from your Toyota
dealer 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.

Maintenance and care
■Brake fluid can absorb moisture
from the air
Excess moisture in the brake fluid
can cause a dangerous loss of brak-
ing efficiency. Use only newly
opened brake fluid.
If any washer does not work or
the warning message appears
on the multi-information display,
the washer tank may be empty.
Add washer fluid.
Fluid
type
FMVSS No.116 DOT 3 or

your hands and eyes and damage
painted surfaces.
If fluid gets on your hands or in
your eyes, flush th e affected area
with clean water immediately.
If you still experien ce discomfort,
see a doctor.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level
to go down slightly as the brake
pads wear out or when the fluid
level in the accumulator is high.
If the reservoir needs frequent
refilling, there ma y be a serious
problem.
Adding the washer fluid
WARNING
■When adding washer fluid
Do not add washer fluid when the

Do not use soapy water or engine
antifreeze instead of washer fluid.
Doing so may cause streaking on
the vehicle’s painted surfaces, as
well as damaging the pump lead-

fluid not spraying.
■Diluting washer fluid
Dilute washer fluid with water as
necessary.
Refer to the freezing tempera-
tures listed on the label of the
washer fluid bottle.

Maintenance and care
install them to the replace-
ment wiper insert.
5 Insert the wiper insert starting
from the claw at the center of
the wiper blade. Pass the
wiper insert through the 3
claws so that it sticks out
from the stopper, and then
pass the wiper insert through
the final remaining claw.
Applying a small amount of washer
fluid to the wiper insert can make it
easier to insert the claws into the
grooves.
6Check that the wiper blade
claws are fitted in the
grooves of the wiper insert.
If the wiper blade claws are not fit-
ted in the grooves of the wiper
insert, grasp the wiper insert and
slide it back and fo rth multiple times
to insert the claws into the grooves.
Lightly lift up the center of the wiper
insert to make the rubber easier to slide.
7
When installing a wiper
blade, reverse the procedure
in step 1.
After installing the wiper blade,
check that the connection is locked.
■Wiper blade and wiper insert
handling
Improper handling may result in
damage to the wiper blades or wiper
insert. If you have any concerns
about replacing the wiper blades or
wiper insert yourself, contact your
Toyota dealer.
NOTICE
■When lifting the windshield
wipers
●When raising the wiper arms off
the windshield, lift up the driver
side first, and then lift up pas-
senger side. When returning the
wipers to their original position,
return the passenger side first.
●Do not lift a windshield wiper by
the wiper blade. Otherwise, the
wiper blade may be deformed.
●Do not operate the wiper lever
when the windshield wipers are
lifted. Otherwise, the wind-
shield wipers may contact the
hood, possibly resulting in dam-
age to the windshield wipers
and/or hood.
