Cleaning windshield and headlamps*
Pull lever 4.
Washer fluid is sprayed onto the windshield and
the wipers are operated for a short time.
When the vehicle lighting system is switched
on, the headlamps are cleaned at regular and
appropriate intervals.
Do not use the washers if there is any
danger that the fluid will freeze on the
windshield. If you do, your vision could be
obscured. Antifreeze should therefore be
added to the fluid, refer to Washer fluid.
Do not use the washers when the washer fluid
reservoir is empty, otherwise you will damage
the washer pump.<
Windshield washer nozzles
The windshield washer nozzles are heated
automatically while the engine is running or the
ignition switched on.
Rear window wiper
1Intermittent operation. When reverse gear
is engaged, the system switches to contin-
uous operation.
2Cleaning the rear window
Do not use the washers when the washer
fluid reservoir is empty, otherwise you will
damage the washer pump.<
Washer fluid
Washer fluid antifreeze is flammable.
Always keep it well away from sparks and
open flames, and store it in the tightly closed
original container, well out of the reach of chil-dren. Comply with the instructions on the con-
tainer.<
Washer fluid reservoir
Fill with water and, if required, with a washer
antifreeze, according to manufacturer's recom-
mendations.
Mix the water and antifreeze before filling
the washer fluid reservoir to make sure
the correct concentration is maintained.<
Capacity
Approx. 6.3 US quarts/6 liters.
Cruise control*
The concept
Cruise control is available for use at speeds of
approx. 20 mph or 30 km/h. The car then stores
and maintains the speed that you specify using
the lever on the steering column. In order to
maintain the specified speed, the system
brakes the vehicle when the engine braking
effect is insufficient on downhill gradients.
Do not use cruise control when driving
conditions are unfavorable for driving at a
constant speed. Otherwise you could lose con-
trol of the vehicle and cause an accident as a
result. Unfavorable driving conditions include,
for example, winding roads, heavy traffic or a
poor road surface, e.g. snow, rain, ice or loose
material.<
Manual transmission
You can shift gears while cruise control is acti-
vated. An indicator lamp notifies you that you

Engine oil
The engine oil consumption is dependent on
driving style and driving conditions.
Checking oil level
Your car is equipped with an electronic oil-level
monitor.
For a precise measurement and display of the
oil level, it is necessary that the engine be at
operating temperature, e.g. after uninterrupted
driving for at least approx. 6.5 miles/10 km. You
can have the oil level displayed while you are
driving, or while the vehicle is at a standstill on a
level surface and the engine is running.
You can have the oil level reading displayed in
the instrument cluster.1.Lightly push button 1 in the turn indicator
stalk up or down repeatedly until the appro-
priate symbol is shown in the display,
accompanied by the word "OIL".
2.Press button 2 in the turn indicator stalk.
The oil level is checked and the reading dis-
played.
