setting sensitivity of the rain sensor
Intermittent mode
Not in vehicles with a rain sensor.
Rotary dial 5 is used to set the wipe interval to
one of four levels.
In addition, the wipe interval is varied automati-
cally depending on road speed.
Rain sensor*
On vehicles with a rain sensor, the wipe interval
is automatically controlled according to rain
intensity. The sensor is mounted on the wind-
shield, directly in front of the interior rearview
mirror.
Deactivate the rain sensor before enter-
ing an automatic car wash. Failure to do
so could result in damage caused by undesired
wiper activation.<
Activating
With the ignition key in position 1 or higher,
move the lever to position 1.
In any case, the wipers will move once across
the windshield.
You can leave the lever continuously in
position1. Then, as long as the ignition key is in position 1 or higher, you only need to activate
the rain sensor.
To do so:
>Turn rotary dial 5 briefly or
>Clean the windshield, refer to Cleaning
windshield and headlamps* below
Adjusting sensitivity
Turn the rotary wheel 5.
Deactivating
Flip the lever to position 0.
Normal wiper speed
When the vehicle is stopped the wipers auto-
matically switch to intermittent wipe, except in
vehicles with a rain sensor.
Fast wiper speed
When the vehicle is stopped the wipers operate
at normal wiping speed, except in vehicles with
a rain sensor.

1Cleaning windshield and headlamps
*
Do not use the washers if there is any
danger that the fluid will freeze on the
windshield, otherwise vision could be
obscured. Antifreeze should therefore be
added to the fluid, refer to Washer fluid on
page46.
Do not operate washing mechanisms when the
washer fluid reservoir is empty, otherwise you
will damage the washer pump.<

Driving

Cleaning windshield
The system sprays washer fluid against the
windshield and activates the wipers for a brief
period.
The windshield washer nozzles are automati-
cally heated
* when the engine is running or the
ignition is on.
Cleaning headlamps*
When the vehicle lighting system is switched
on, the headlamps are cleaned at regular and
appropriate intervals.
Washer fluid
Washer fluid antifreeze is flammable. For
this reason, keep it away from sources of
flame and store it only in its original container.
Store it so that it is inaccessible to children.
Comply with the instructions on the con-
tainer.<
Washer fluid reservoir
Fill with water and, if required, with antifreeze
according to its manufacturer's recommenda-
tions.
Mix the water and antifreeze before filling
the washer fluid reservoir to make sure
the correct concentration is maintained.<
Capacity
Approx. 5.3 US quarts/5 liters.
Cruise control*
The concept
Cruise control is available at speeds of at least
approx. 20 mph/30 km/h. The car stores and
maintains the speed that you specify with the
lever on the steering column.
Do not use cruise control if conditions are
unfavorable for driving at a constant
speed, e.g. due to winding roads, dense traffic,
or poor road conditions such as snow, rain, ice,
loose surface, etc. Otherwise, you could lose
control of the vehicle and cause an accident.<

To maintain current speed
Tap the lever, arrow 1, or pull it briefly, arrow 2.
The car's current speed is stored and main-
tained. If, on downhill grades, the engine brak-
ing effect is not sufficient, the controlled speed
can be exceeded. Speed can drop on uphill
grades if the engine output is insufficient.
To increase speed
Tap the lever repeatedly, arrow 1, until the
desired speed is reached.
Every time you tap the lever, the speed
increases by approx. 1 mph/1 km/h.

When you park the car, all its outside lamps are
switched off automatically if the light switch is in
position0, 2 or 3.
If you want the parking lamps to be on, turn the
switch to position1.
Parking lamps
In switch position1, the front, rear and side
vehicle lighting is switched on. You can use the
parking lamps to signal the position of the vehi-
cle when it is parked. For the additional option
of roadside parking lamps on one side of the
vehicle only, refer to page60.
The parking lamps will discharge the bat-
tery. Therefore, do not leave them on for
unduly long periods of time, otherwise the bat-
tery might not have enough power to start the
engine.<
Low beams
The low beams light up when the light switch is
in position 2 and the ignition is on.
Defective bulb
The indicator lamp lights up:
At least one bulb of the vehicle's exte-
rior lighting has failed.
For replacing bulbs refer to page98.
Automatic headlamp control*
When the switch is in position3, the low beams
are switched on and off automatically depend-
ing on ambient light conditions, e.g. in a tunnel,
in twilight, or if there is precipitation.
When driving into tunnels with bright overhead
lights, there may be a delay before the head-
lamps come on.
The headlamps may also come on when the
sun is sitting low on a blue sky.
The low beams remain switched on inde-
pendent of the ambient lighting condi-
tions when you switch on the fog lamps
*.<
If desired, the light switch can remain in
position3. The exterior lamps are automatically
switched off after the vehicle is parked.
The automatic headlamp control cannot
serve as a substitute for your personal
judgment in determining when the lamps
should be switched on in response to ambient
lighting conditions. For example, the system
cannot detect fog or hazy weather. To avoid
safety risks, you should always switch on the
lamps manually under these conditions.<
You can have the sensitivity of your vehi-
cle's automatic headlamp control
adjusted.<
Daytime running lamps*
If desired, the light switch can remain in the
automatic headlamp control position. The exte-
rior lamps are automatically switched off after
the vehicle is parked.
In the Parking lamps position, the parking lamps
come on after the ignition is switched off.

Lamps

described in the section about parking lamps.
You can have the daytime running lamps
activated/deactivated on your vehicle.<
Pathway lighting
If you activate the headlamp flasher after park-
ing the car, with the lights switched off, the low
beams come on and remain on for a certain
time.
You can have this function activated/
deactivated as well as the duration of the
pathway lighting set.<
LIGHTS ON warning
Whenever you open the driver's door after hav-
ing turned the key to position 0, you will hear an
acoustic signal for a few seconds to remind you
that the lamps have not been switched off.
