Shift lights
To achieve the best vehicle acceleration with
a sporty driving style in the Sequential mode,
shift lights in the Head-Up Display
* indicate the
optimum shifting point briefly before reaching
the maximum rpm.
1.Switch on Head-Up Display, refer to Head-
Up Display on page77.
2.Select display "M View" on Head-Up Dis-
play, refer to Selecting displays on page77.
The current engine speed is highlighted on
the tachometer.
3.When approaching the maximum rpm, yel-
low illuminated fields1 of the tachometer
consecutively indicate the approaching
upshift point.
4.Shift at the latest when the red indicator
field lights up2.
When the permissible maximum rpm is
reached, the entire tachometer beings to flash.
When the maximum rpm is exceeded, the fuel
supply is cut off to protect the engine. Always
avoid engine speeds in this range.
M Engine Dynamic Control
With M Engine Dynamic Control you can influ-
ence how sporty the reaction of your vehicle to
accelerator pedal movements is to be. Three
programs are available for engine control.
"P 400" program
In the "P 400" program the engine reacts gently
to the movement of the accelerator pedal. This
is, for example, ideal for city driving or driving on
snow. In the process, the fuel consumption is
minimal and the engine output is reduced.
"P 500" program
The "P 500" program provides maximum per-
formance and more spontaneous reaction of
the engine to accelerator pedal movements.
"P 500 Sport" program
In the "P 500 Sport" program the engine reacts
especially spontaneously and uncompromis-
ingly sporty with maximum performance to
accelerator pedal movements.
Selecting program
Each time the engine is started, the "P 400"
program is activated.
Press the POWER button to activate the
"P 500" program. Pressing the POWER button
repeatedly switches between the programs
"P 400" and "P 500".
You can also activate your preferred program
with the button on the steering wheel, refer
to MDrive on page46. You can only activate the
"P 500 Sport" program with MDrive.
For the programs "P 500" and "P 500 Sport"
the LED in the POWER button lights up.

The system reverts to operation at normal
speed whenever the vehicle is stationary.
Rain sensor
Wiper operation is controlled automatically as a
function of the rain intensity. The rain sensor is
located on the windshield, directly in front of the
interior rearview mirror.
Activating rain sensor
Press the button, arrow3. The LED in the but-
ton lights up.
Adjusting rain sensor sensitivity level
Turn the knurled wheel5.
Deactivating rain sensor
Press the button again, arrow3. The LED goes
out.
Deactivate the rain sensor when passing
through an automatic car wash. Failure to
do so could result in damage caused by undes-
ired wiper activation.<
Cleaning windshield and headlamps
Pull the lever, arrow4:
The system sprays washer fluid against the
windshield and activates the wipers for a brief
period.
When the vehicle lighting is switched on, the
headlamps are simultaneously washed at
appropriate intervals.
Do not use the washers if there is any
danger that the fluid will freeze on the
windshield. If you do so, your vision could be
obscured. To avoid freezing, use a washer fluid
antifreeze, refer to Washer fluid. Do not use washers when the washer fluid reservoir is
empty, as this will damage the washer pump.<
Windshield washer nozzles
Both windshield washer nozzles are automati-
cally heated with the engine running or the igni-
tion switched on.
Washer fluid
Washer fluid antifreeze is flammable.
Always keep it well away from sparks and
open flames, and store it in tightly closed con-
tainers well out of the reach of children. Always
follow the instructions for use provided on the
containers.<
Washer fluid reservoir
All washer jets are supplied from one reservoir.
Fill with water and – if required – with a washer
antifreeze, according to manufacturer's recom-
mendations.
In order to maintain the mixture ratio, mix the
washer fluid before filling.<
Capacity
Capacity approx. 5.3 US quarts/5 liters.
Cruise control
The concept
The cruise control is available for use at speeds
of approx. 20 mph/30 km/h and higher. The
vehicle stores and maintains the speed that you
set using the lever mounted on the steering col-
umn.
Page 60 of 227

Driving
58 Do not use the cruise control under driv-
ing conditions that do not permit a con-
stant speed, e.g. when driving on winding
roads , in heavy traffic o r in poor roa d co nditions
such as snow, rain, ice, and loose road surface.
Otherwise, you could lose control of the vehicle
and cause an accident.<

4Resuming stored speed
Maintaining speed, storing speed, and
accelerating
Press lever to resistance point, arrow 1:
The system maintains and stores the current
vehicle speed. The display1 in the speedome-
ter, see below, indicates this regulated speed.
Every time you press the lever, the vehicle's
speed increases by roughly 1 mph/1 km/h.
Press the lever to the resistance point and
hold it:
The vehicle accelerates without pressure on
the accelerator pedal. The system maintains
and stores your current speed as soon as you
release the lever.
Press the lever beyond the resistance point:
Increase speed by 5 mph/10 km/h.
The vehicle may accelerate beyond the regu-
lated speed on steep downhill stretches where
the engine's braking action alone may not be
sufficient to slow the vehicle. Speed can drop on uphill grades if the engine output is insuffi-
cient.
Maintaining speed, storing speed, and
decelerating
Pull the lever, arrow2:
Functions are the same as1, only the vehicle
speed is reduced.
Interrupting cruise control
Press the lever up or down, arrow3.
Cruise control is also interrupted automatically:
>When you apply pressure to the brake pedal
>For manual shifting with the shift paddles or
the selector lever
>When the DSC comes on
Resuming stored speed
Press button4:
The vehicle accelerates to and maintains the
stored speed.
Deactivating system
When the ignition is switched off, the system is
deactivated and the stored speed is deleted.

The advance warning field, arrow1, and the red
warning field, arrow2, change depending on
the engine temperature. As the engine temper-
ature rises, the permissible engine speed also
increases.
Avoid allowing the engine speed to rise as far as
the advance warning field whenever possible.
Always avoid engine speeds in the red warning
field.
In this range, the fuel supply is interrupted to
protect the engine.
Coolant temperature
Should the coolant and therefore the engine
become too hot, a warning lamp lights up. In
addition, a message appears on the Control
Display.
Checking coolant level, refer to page178.

Engine oil temperature gauge
The general operating temperature lies
between 1757/806 and 2507/1206. Do
not exceed a value of approx. 2657/1306.
If the engine oil temperature is too high, the per-
missible engine speed, and with it the available
engine output is reduced.
Fuel gauge
Fuel tank capacity: approx. 18.5 gallons/
70 liters. You can find information on refueling
on page168.
If the tilt of the vehicle varies for a longer period,
when you are driving in mountainous areas, for
example, the indicator may fluctuate slightly.
Reserve
After the reserve quantity has been reached, a
message briefly appears on the Control Display;
the remaining range is shown in the computer.
Below a range of approx. 30 miles/50 km, the
message remains on the Control Display.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km, otherwise engine functions are not
ensured and damage can occur.<

If the display drops to +377/+36, a signal
sounds and a warning lamp lights up. A mes-
sage appears on the Control Display. There is
an increased danger of ice.
Ice can form even at temperatures above
+377/+36. Drive carefully, especially
on bridges and shaded roadways; otherwise,
your risk of accident increases.<
You can set the unit of measure 7 or 6 on the
Control Display, refer to Units of measure on
