Steering column switches

The car uses two steering column switches mounted on the steering column.

On some vehicles, the sound signal is turned on by the turn signal and headlight switches, and on others - by the windshield wiper and washer switch

Left turn signal switch

The switch automatically returns to position I or II after turning. A – non-fixed position of the lever for briefly turning on the turn signal.

When the lever is moved from position I towards you to the non-fixed position, the high beam headlights turn on while the lever is held in this position.

Scheme of operation of the steering column switches: a - left switch for direction indicators, headlights (sound signal); I - low beam headlights (if the handle of the central light switch is pulled out all the way); II - high beam headlights (if the handle of the central light switch is pulled out all the way); V or III - left turn enabled; VI or IV - right turn is enabled. b - Right switch for windshield wiper, windshield washer (sound signal); 0 - windshield wiper off; I - low speed windshield wiper is on; II - high speed windshield wiper is on; III - the windshield wiper operates intermittently

The sound signal (option 1) is activated by pressing the lever button from any position.

For a switch without a sound signal (option 1), moving the lever toward you (arrow) from position 0 briefly turns on the washer and wiper.

For a switch with an audible signal (option 2), the washer and wiper are switched on briefly by moving the lever away from position 0 (arrow B).

The sound signal is activated by moving the lever towards you from any position (arrow C).

The washer and signal can be turned on at any position of the lever.
