Checking the clock

Check current time, adjust if necessary.

1. The clock is set in the multi-function display.
2. Press clock button on instrument cluster.
3. Set the time using the rocker switch on the wiper switch.
4. Press reset switch on the wiper switch.

Compare time displayed in instrument cluster with time displayed in PCM (if available) and adjust the time in PCM also if necessary.

Adjusting main headlight

The vehicle must be on a horizontal surface.

Make the adjustment with the regulator switch set to 0 (headlight beam adjustment).

Use a flexible screwdriver 9703 with a hexagon bit to adjust the headlights.

Using a headlight adjustment unit, make the adjustment with the vehicle ready for driving (fuel tank full, driver's seat occupied by a person or loaded with Mass 75 kg; tire pressures must correspond to specified values).







1. Press down cover -1- in engine compartment and remove it.
2. Turn on the ignition, turn on dipped beam and high beam headlights.
3. Check setting and adjust if necessary.

Adjusting:

Set headlight adjustment unit to 10 cm/10 m (1%).

With this alignment, preference must be given to the central zone around the salient point of the light/dark limit.

NOTE:
- The distance between the headlights and the adjustment unit should be as small as possible.
- It should not exceed 30 cm, because at greater distances it is no longer possible to define the formation of the light/dark limit in the adjustment unit clearly.







The vertical/side adjustment of the dipped beam/high beam highlight is made first: adjustment -A- and -B-.

4. To do this, line up the light/dark borderline running upwards at an angle on the right-hand side with the dotted 15 degrees line of the adjustment unit.







5. The dipped beam headlight is then adjusted horizontally: adjustment -A- and -B-.







To do this, line up the left, horizontal section of the light/dark limit (when driving on the right) with the dotted horizontal line of the adjustment unit.







6. Check auxiliary high beam headlight and, if necessary, adjust the side setting using -A- and -B-.
7. In the case of Xenon headlights, the ignition must be switched off and on after the adjustment has been made with the lights switched on.
8. After this, the adjustment must be checked again.
9. Fit cap again.
