■The windshield wiper and washer can be operated when
The “ENGINE START STOP” switch is in IGNITION ON mode.
■Raindrop sensor
●If the temperature of the raindrop sensor is 194°F (90 °C) or higher, or 5 °F
( -1 5 °C) or lower, automatic operation may not occur. In this case, operate
the wipers in any mode other than “AUTO”.
■AUTO mode
If the wiper switch is turned to AUTO position while the “ENGINE START STOP”
switch is in IGNITION ON mode, the wiper will operate once to show that AUTO
mode is activated.
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the wind-
shield washer fluid reservoir.
Wash/wipe operation
Wipers operate automatically.
(With “AUTO” selected, after
operating several times, the wip-
ers operate one more time after
a short delay to prevent drip-
ping.)
●The sensor judges the amount of raindrops.

■Caution regarding the use of windshield wipers in AUTO mode
The windshield wipers may operate unexpectedly if the sensor is touched or the

anything else do not become caught in the windshield wipers.
NOTICE
■When the windshield is dry
Do not use the wipers, as they may damage the windshield.

Winter driving tips
Carry out the necessary preparations and inspections before driving the
vehicle in winter. Always drive the vehicle in a manner appropriate to the
prevailing weather conditions.
■Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspect the level and specific gravity of
battery electrolyte.
● 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.
●Tire inflation pressure falls in winter as the outside temperature
falls. Add 2.9 to 4.3 psi (20 to 30 kPa, 0.2 to 0.3 kgf/cm2 or bar)
to the standard tire inflation pressure.
