■The windshield wiper and washer can be operated when
The engine switch is in IGNITION ON mode.
■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, the last sweep will not happen while the vehicle is moving.
■Effects of vehicle speed on wiper operation
●Intermittent windshield wipers interval changes when the vehicle is stopped.
●With low speed operation selected, wiper oper ation will be switched from low speed to
intermittent operation only wh en the vehicle is stationary.
■Raindrop sensor
●If AUTO mode is selected while the engine switch is in IGNITION ON mode, the wip-
ers will operate once to show that AUTO mode is activated.
●If the temperature of the raindrop sensor is 185°F (85°C) or higher, or -22°F
(-30°C) or lower, automatic operation ma y not occur. In this case, operate the
wipers in any mode other than AUTO mode.
Switching between the intermittent windshield wipers and rain-sensing
windshield wipers (vehicles with rain-sensing windshield wipers)
●The raindrop sensor judges the amount of
raindrops.
An optical sensor is ad opted. It may not oper-
ate properly when sunlight from the rising or
setting of the sun inte rmittently strikes the
windshield, or if bugs etc. are present on the
windshield.

●If something bumps against the windshield
●If you directly touch the raindrop sensor body or if something bumps into the raindrop
sensor
■Precautions regarding the exhaust pipes and rear bumper diffusers
Exhaust gases cause the exhaust pipes and rear bumper diffusers to become quite hot.
When washing the vehicle, be careful not to touch the pipes and rear bumper diffusers
until they have cooled sufficiently, as touc hing hot exhaust pipes and rear bumper dif-
fusers can cause burns.
■Precaution regarding the rear bumper with Blind Spot Monitor (if equipped)

NOTICE
■Application of coatings to
the vehicle body (GS F)
Do not apply any kind of coating to the vehicle body as doing so may damage the paint
or reduce its durability.
■To prevent paint deterioration and corrosion on the body and components (aluminum
wheels etc.)
●Wash the vehicle immediately in the following cases:
• After driving near the sea coast
• After driving on salted roads
• If coal tar, pollen or tree sap is present on the paint surface
• If dead insects, insect droppings or bird droppings are present on the paint surface
• After driving in an area contaminated wi th soot, oily smoke, mine dust, iron pow-
der or chemical substances
• If the vehicle becomes heavily soiled with dust or mud
• If liquids such as benzene and gasoli ne are spilled on the paint surface
●If the paint is chipped or scratched, have it repaired immediately.
●To prevent the wheels from corroding, remove any dirt and store in a place with low
humidity when storing the wheels.
■Cleaning the exterior lights
●Wash carefully. Do not use organic subs tances or scrub with a hard brush.
This may damage the surfaces of the lights.
●Do not apply wax to the surfaces of the lights.
Wax may cause damage to the lenses.
■When using an automatic car wash (vehicles with rain-sensing windshield wipers)
Turn off AUTO mode of the wiper to prevent the wiper from operating. ( P. 229)
If AUTO mode is selected, the wipers may operate and the wiper blades may be dam-
aged.
■When using a high-pressure car wash
●When washing the vehicle, do not let water from the high-pressure washer directly hit
the camera or the area around the camera. Due to the shock from high-pressure
water, it is possible that the device may not operate normally.
●Do not bring the nozzle tip close to boots (rubber or resin manufactured cover), con-
nectors or the following parts. The parts may be damaged if they come into contact
with high-pressure water.
• Traction related parts
