Windshield washer nozzles
The windshield washer nozzles are heated
automatically while the engine is running or the
ignition is switched on.
Washer fluid
Washer fluid antifreeze is flammable.
Therefore, keep it away from ignition
sources and only store it in the closed original
container that is kept ou t of reach of children,
otherwise there is a risk of personal injury.
Comply with the instructions on the con-
tainer. <
Washer fluid filler neck
Only refill washer fluid when the engine is
cool to avoid contac t with hot engine
parts. Otherwise, fluid spills constitute a fire
hazard and a risk to personal safety. <
All washer nozzles are supplied with washer
fluid by the same 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 at
constant speed is prevented by adverse
conditions, e.g. winding roads, dense traffic,
poor visibility or unfavorable road conditions
due to, e.g. snow, rain, ice or loose surfaces.
Otherwise you could lose control of the vehicle
and cause an accident as a result. <
Manual transmission
You can shift gears while cruise control is acti-
vated. An indicator lamp notifies you that you
should shift gears wh en you drive for an
extended period at very high or very low engine
speeds, or the system is deactivated.

Maintaining current speed
Tap the lever, arrow 1, or pull it briefly, arrow 2.
The car's current speed is stored and main-
tained. It is displayed on the speedometer and
briefly in the instrument cluster.
On uphill gradients, it may prove impossible to
maintain the set speed if current engine power
output is insufficient. If the engine braking
effect is insufficient on downhill slopes, the sys-
tem will brake the vehicle slightly.
Increasing desired speed
Repeatedly press the lever to the resistance
point or beyond, arrow 1, until the desired
speed is reached.
> Each time the lever is pressed to the resis-
tance point, the desired speed is increased
by approx. 1 mph or 1 km/h.
> Each time the lever is pressed beyond the
resistance point, the desired speed is
increased by up to 5 mph or 10 km/h.
The system stores and maintains the speed.
Accelerating using the lever
Accelerating slightly:
Press the lever to the resistance point, arrow 1,
and hold until the desired speed is reached.
Accelerating significantly:
Press the lever beyond the resistance point,
arrow 1, and hold until the desired speed is
reached.
The vehicle accelerates without pressure on
the accelerator pedal. The system stores and
maintains the speed.
Decreasing speed
Repeatedly pull the lever to the resistance point
or beyond, arrow 2, until the desired speed is
displayed.
> Each time the lever is pulled to the resis-
tance point, the desired speed is decreased
by approx. 1 mph or 1 km/h.
> Each time the lever is pulled beyond the
resistance point, the desired speed is
reduced by up to 5 mph o r 10 km/h until the minimum speed of 20 mph or 30 km/h is
achieved.
The system stores and maintains the speed.
Interrupting the system
Tap the lever upwards or downwards, arrow 3.
The displays in the speedometer change color.
In addition, the system is automatically deacti-
vated:
> When you brake the vehicle
> When you switch gears very slowly or shift
to neutral in cars with a manual trans-
mission
> When you engage selector lever position N
in cars with an automatic transmission
> When you engage transmission position N
in 7-gear sport automatic transmissions
with a dual clutch
> When you activate the DTC Dynamic Trac-
tion Control or deactivate DSC.
> When DSC or ABS is intervening
Cruise control is not de activated by depressing
the accelerator pedal. Once the accelerator
pedal is released, the st ored speed is achieved
again and maintained.
Warning lamp
The warning lamp comes on, for
example, when cruise control has
been deactivated as a result of DSC
intervention. A message appears on the Control
Display.
Deactivating the system
> Press the lever upward or downward twice,
arrow 3.
> Switch off the ignition.
The stored speed is cleared.
Resuming a speed stored beforehand
Press the button, arrow 4. The last stored
speed is resumed and maintained.
