PRECAUTION

PRECAUTION FOR DISCONNECTING CABLE FROM NEGATIVE BATTERY TERMINAL

NOTICE:

When disconnecting the cable from the negative (-) battery terminal, initialize the following systems after the cable is reconnected.

PRECAUTIONS FOR AUTO WIPER SYSTEM

(a) When the engine switch is on (IG) and the front wiper switch is in AUTO, the rain sensor may operate the front wipers if the rain sensor sensing portion of the windshield glass is touched by a hand or if something moist, such as a wet cloth, is brought near. This may lead to injury or damage to the vehicle.

(b) When the engine switch is on (IG) and the front wiper switch is in AUTO, the rain sensor may operate the front wipers if the rain sensor or parts around the rain sensor (windshield glass, rain sensor cover, etc.) are vibrated.

(c) If the windshield glass is coated with a water-repellent coating, the rain sensor may not correctly detect the amount of raindrops that strike the windshield and the auto wiper system may not operate normally.

(d) As the rain sensor is an optical sensor, if sunlight intermittently strikes the windshield glass or the rain sensor sensing portion of the windshield glass is dirty, the auto wiper system may not operate normally.

PRECAUTION FOR WASHER NOZZLE ADJUSTMENT

(a) Do not clean or adjust the washer nozzle with a safety pin, etc. because:

(1) The washer nozzle tip is made of resin and may be damaged.

(2) Adjustment is not necessary for this spray type washer nozzle. If it is necessary to change the nozzle angle, replace the washer nozzle with one that has a different nozzle angle.
