Check of control tools and bulbs

Take the wheel and serially check:


  1. Hours work with shooters?
  2. Include ignition. The control bulb of a battery charging, a control bulb of ABS (the control bulb of ASR (too about 2 c) dies away approximately through 2 c), a control bulb of a safety cushion have to light up (dies away approximately through 10 c).
  3. At ignition inclusion the symbol of a control lamp while comparison of data of the blocking preventing departure of the car, ignition key and car is carried out also for a while lights up. At the switched-on emergency brake the control bulb of the parking brake also burns.
  4. Cars without system of automatic control: in a light field above between round devices the alarm bulb of cooling liquid, a control bulb of pressure of oil and a control bulb of level of brake fluid blinks.
  5. In cars with system of automatic control in a light field at inclusion of ignition there is an inscription of "Bremslicht" – "stoplight fires". After short percussion on a pedal of a brake the sign "OK" has to flash.
  6. With some delay will move on a scale of an arrow of the indicator of amount of fuel and the indicator of temperature of cooling liquid (only at the warmed engine).
  7. If additional devices are built in, voltmeter and the indicator of temperature of engine oil, ready to work (signal only at the warmed engine).
  8. Include indexes of turns: one of green control bulbs of the index of turns rhythmically flashes – depending on the chosen direction. Press the switch of the alarm system: the control bulb of the alarm system (in the switch) and both control bulbs of indexes of turns blinks.
  9. Pull the lever of indexes of turns to a steering wheel: the control bulb of indexes of turns has to flash.
  10. Start the engine – the measuring instrument of number of turns works?
  11. During a trial trip check work of a speedometer and the indicator(s) of temperature.
