Controls, Safety, Instruments The rain sensor remains switched off if the wiper
lever is already in position 1 when the ignition is
switched on.
To switch the rain sensor on again:
fMove wiper stalk to position 0 and then to
position1 – switching on is confirmed by one
wipe of the windscreen – or
fOperate windscreen washer system 5–
switching on is confirmed by three wipes of the
windscreen – or
fChange the sensitivity of the rain sensor with
four-stage switch A.Changing the sensitivity of the rain sensor
Sensitivity can be set with switch A in 4 stages:
fAdjust switch A upwards –
high sensitivity.
The setting is confirmed by one wipe of the
windshield.
fAdjust switch A downwards –
low sensitivity.
2 – Front windshield wiper – slow
fMove wiper stalk upwards to the second click.
3 – Front windshield wiper – fast
fMove wiper stalk upwards to the third click.
At speeds of less than approx. ca. 2.5 mph
(4 km/h), rain sensor operation mode is automat-
ically activated if the windshield wiper is switched
on. If you exceed a speed of approx. 5 mph
(8 km/h), the system switches to the pre-selected
wiper level.
4 – Front windshield wiper – one-touch oper-
ation
fMove wiper stalk downwards. The front wind-
shield wipers go through one wipe cycle.5 – Front windshield wipers and washer sys-
tem
fPull wiper stalk towards the steering wheel.
The washer system sprays and wipes while the
lever is pulled towards the steering wheel.
When the wiper lever is released, a few drying
wipes are executed.
Headlight washer (on vehicles with Bi-Xe-
non headlights):
The washer sprays only while low beam or high
beam is switched on.
To activate the headlight washer system, the
wiper lever must be pulled for a longer period
of time.
The spray duration is limited.
Maintenance note
fIf heavily soiled, repeat wash.
fPersistent dirt (e.g. insect remains) should be
regularly removed.
Please observe the chapter “CAR CARE IN-
STRUCTIONS” on Page 265.
Thefront windscreen washer nozzles are heat-
ed when the ignition is on, as a precaution against
freezing.

Practical Tips, Minor Repairs
Headlight AdjustmentfCheck tire pressure and adjust if necessary.
fPlease observe the chapter “TIRE PRESSU-
RES, COLD” on Page 361.
fPlease observe the chapter “REPLACING BUL-
BS” on Page 336.Adjustment
The adjustment is made with the vehicle ready to
drive and the fuel tank completely filled.
The driver's seat must be loaded by a person or a
165lbs. (75kg) weight and the tire pressures must
meet the prescribed values. After being loaded,
the car must be rolled a few meters so that the
suspension can settle.
For checking the headlight adjustment, the verti-
cal position of the cutoff of the lowbeam (see fig.)
has to be projected on a vertical screen (wall) in
distance of 7.5 m (24.6 ft.) from the front lens of
the headlamp.The correct position of the cutoff is
7.5 cm (3.0 in.) at 7.5 m or 24.6 ft. (0.4°) below
a horizontal line, x cm from ground to the center
of the headlamp lens.
Lateral adjustment of the headlights should be
carried out at a specialist workshop with an optical
adjustment unit.
Distance
Visual aim shall be performed at not less than
7.5 m (this value is a rounded down conversion
from the 25-foot distance typical of field aim using
a screen). The 7.5 m (24.6 ft.) distance is mea-
sured from the headlamp lens to the viewing
screen.
Floor
The surface upon which the vehicle rests is flat
and approximately level.
Screen
The screen upon which headlamp beams are pro-
jected is perpendicular to the floor and the vehi-
cle's longitudinal axis, flat, uniformly light in color,
unobstructed, and wide and high enough to ac-
commodate the vehicle beam patterns to be
aimed.
The screen should be wide enough to provide at
least 3.3 ft. (1 m) of space outboard of the vehi-
cle's headlamp spacing.
