1.15. Switches and switches


Fig. 1–43. An arrangement of switches and switches on the panel of devices:
1, 8 – regulators of heating of seats; 2 – antifog headlights; 3 – back antifog light; 4 – heating of back glass; 5 – the emergency light alarm system; 6 – a sun-protection curtain of back glass; 7 – moving of back headrests


1, 8 – regulators of heating of seats (fig. 1–43).
The back and seat pillow can be warmed up by an electric current at the included ignition.
Regulator 1 joins and the heating of a seat of the driver, by a regulator 8 – heating of a seat of the forward passenger is smoothly regulated.
The heating of back sitting joins and smoothly changes the regulators located in a back part of the central console: a – at the left and b – on the right (fig. 1–44).

Fig. 1–44. An arrangement of regulators of heating of a back seat: and – at the left, b – on the right


Seats are warmed up only in that case when they are loaded by body weight.
If the heating is included, number marks on a regulator blink.
For heating deenergizing it is necessary to turn a disk regulator in a starting position.

2 – antifog headlights burn at included distant or a passing light of headlights.
At inclusion of antifog headlights the control lamp in the switch lights up.

3 – back antifog light burns at included distant or a passing light of headlights, and on cars with antifog headlights – and at inclusion of antifog headlights.
At inclusion of back antifog lanterns the control lamp in the switch lights up.
Because of strong blinding influence back antifog lanterns should be included only at a low visibility.

4 – heating of back glass functions only at the included ignition. When heating is included, the control lamp in the switch burns.
On cars with the electric drive of adjustment of position of external mirrors heating of their surfaces joins simultaneously with inclusion of heating of back glass.
As soon as back glass will be released from запотевания or ice, it is necessary to switch off heating immediately: current consumption reduction favorably influences the fuel expense.
At cars with the conditioner heating of back glass automatically is switched off in 10 minutes
If on the car mirrors with heating at inclusion of a heater of back glass mirror heating joins also are established.

5 – the emergency light alarm system functions and at the switched off ignition.
The alarm system include in following cases:
– A stop of the car because of technical malfunction;
– Road and transport incident;
– At achievement of the end of a road stopper.
At the included alarm system all indexes of turn, and also control lamps of inclusion of indexes of turn and a control lamp in the switch blink simultaneously.

6 – a sun-protection curtain of back glass. Quickly press the switch – the curtain will reveal and then will automatically be switched off. During curtain moving it is possible to change a direction of movement by pressing the switch in an opposite direction.

7 – moving of back headrests. Back headrests with the electric drive can be moved on height, pressing the corresponding switch panels of devices.

The proof-reader of light of headlights. By means of the adjusting mechanism with the electric drive it is possible to regulate smoothly an angle of slope of light of headlights according to car loading. Thanks to it blinding action of headlights decreases for the driver of counter transport and visibility improves.
For lowering of a ray of light turn a regulator from a substantive provision (0) downwards.
Regulator positions correspond to the following loading of the car:
0 – passengers on forward seats, a luggage carrier empty;
1 – passengers on all seats, a luggage carrier empty;
II – passengers on all seats, the luggage carrier is loaded;
III – only the driver, the luggage carrier is loaded.

The note
On cars with gas-discharge (xenon) lamps at inclusion of ignition position of headlights is automatically regulated depending on car loading.

The protivobuksovochnaja system (ASR) with reduction of a twisting moment of the engine prevents proslipping of wheels at acceleration of all-wheel drive cars by decrease in capacity of the engine. The system works in all high-speed range together with antiblocking system. At infringements in work ABS the system does not function.
The protivobuksovochnaja system joins automatically at engine start-up. She can be switched on and off at will pressing the switch.
When the system is switched off, control lamp ASR burns.
Usually the system should be always included. System switch off only in exceptional cases when proslipping of wheels is necessary, for example, at movement with chains противоскольжения, at movement on deep snow or a friable ground, at rocking of the got stuck car.
After overcoming of such sites it is necessary to include again противобуксовочную system.

The note
For trouble-free operation maintenance противобуксовочной systems it is necessary to establish identical tyres on all wheels.

Podrulevye switches of indexes of turn and light of headlights

A – the illumination switch can occupy positions:
0 – illumination is switched off;
1 – dimensional light is included;
2 – it is included distant or a passing light.
External illumination works only at the included ignition.

In – the switch of indexes of turn and light of headlights. Turn indexes work only at the included ignition.
For inclusion of the index of the right turn translate the switch upwards, for inclusion of the left turn translate the switch downwards.
At the included index of turn the control lamp blinks.
After passage of turn the turn index is automatically switched off.

Giving of a signal of turn before lane change. The switch should be pressed upwards or down to the increase moment противодавления and to detain in this position – a control lamp should blink simultaneously with the turn index.

Light signal. The podrulevoj switch to move to a steering wheel, the control lamp of a headlight thus will light up.

Switching on distant or a passing light of headlights. Switching at included near or a headlight is carried out by switch moving forward. At switching on a headlight the control lamp of a headlight lights up.
Parking light. Parking light lamps burn only at the switched off ignition.
Parking light lamps on the right – the switch upwards.
Parking light lamps at the left – the switch downwards.
After вынимания a key from the ignition lock at an open door of the driver the buzzer sounds.

Cruise-control
Cruise-control provides a constancy of the set speed (over 30 km/h) if the engine can provide it, and releases the driver from necessity pressing a pedal of an accelerator it to support.

The prevention
Cruise-control should not be included at high intensity of a traffic and in adverse road conditions (the iced over or wet road, гравийное a covering).

The cruise-control operate with the help сдвижного the switch And and keys In, located on подрулевом the switch of indexes of turn and light of headlights.
To include cruise-control, shift the switch And in position EIN.
When desirable speed of movement is reached, quickly enough to press a key In (FIX). Now it is possible to remove a foot from an accelerator pedal. Speed of movement increase in the usual way – pressing an accelerator pedal. After release pedals cruise-control will lower speed of movement to a preset value. If the set speed has been exceeded for 5 mines more than on 10 km/h, it is necessary to establish necessary speed of movement again.

The prevention
To come back to initial speed of movement follows only in case of conformity of speed to concrete traffic conditions.
The established speed reduce pressing a key of Century
By each easy pressing of a key At speed in steps decreases. If to hold a key In pressed, speed decreases automatic moving of draught of an accelerator. At release keys the reached speed is entered into memory.
If to release a key at speed below 30 km/h, the store is cleared and it is necessary to establish again a key In desirable speed after achievement by the car of speed over 30 km/h.
The established speed can be raised, without pressing an accelerator pedal, moving of the switch And to position AUFN.
By each easy pressing on сдвижной the switch to the left speed in steps raises. If to shift the switch to the left and to keep it in this position, speed increases automatic moving of draught of an accelerator. At release the switch the reached speed is entered into memory.

Short-term switching-off of the cruise-control
Cars with a mechanical transmission
For short-term switching-off of the cruise-control it is necessary to press a brake or coupling pedal or to shift the switch And in position AUS (without its fixing).
Brought by this moment in memory value of the set speed remains.
For returning to earlier set speed follows after release to a pedal of coupling or a brake to shift the switch And against the stop to the left.

The prevention
To come back to earlier set speed of movement follows only when this speed is not too high for directly forthcoming traffic conditions.

Cars with an automatic transmission
Short-term switching-off of the cruise-control is made by pressing a brake or coupling pedal or shift of the switch And in position AUS (without its fixing).
Brought by this moment in memory value of the set speed remains.
For returning to earlier set speed follows after release to a pedal of coupling or a brake to shift the switch And against the stop to the left.

Preventions
To come back to earlier chosen speed of movement follows only when this speed is not too high for directly forthcoming traffic conditions.
Besides, cruise-control is temporarily disconnected and when the selector is translated in position N or 1 (a 4-step transmission), and also in a position 2 (a 5-step transmission).
Brought by this moment in memory value of the set speed is erased from memory.

Storing of the chosen speed.
If at short-term switching-off in memory there was no speed or the set speed has been erased, it is possible to establish new desirable speed one of next ways:
Shift the switch And against the stop to the left and hold it in this position until desirable speed will be reached;
Quickly press a key of Century In memory speed at the moment of key pressing will be brought.

Cruise-control deenergizing
Cars with a mechanical transmission
Definitive deenergizing of the cruise-control is carried out by shift of the switch And against the stop to the right (fixing in position АUS) or on the motionless car – ignition deenergizing.

Cars with an automatic transmission
Definitive deenergizing of the cruise-control is carried out by selector moving:
• in position Р, N or R;
• in a position 1 or 2 (a 4-step transmission);
• on the standing car ignition deenergizing.
