wash, follow the instructions in Car washes, re‐
fer to page  259.
Starting the engine
General information Enclosed areas
Do not let the engine run in enclosed
areas; otherwise, breathing of exhaust fumes
may lead to loss of consciousness and death.
The exhaust gases contain carbon monoxide, an
odorless and colorless but highly toxic gas.◀
Unattended vehicle

shift to neutral or engage transmission posi‐
tion P and set the handbrake firmly; otherwise,
the vehicle may begin to roll.◀
Frequent starting in quick succession
Avoid repeated futile attempts at starting
the car and avoid starting the car frequently in
quick succession. Otherwise, the fuel is not
burned or is inadequately burned, and there is
the danger of overheating and damaging the
catalytic converter.◀Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving right
away, but at moderate engine speeds.

Automatic Engine Start/Stop
Function
The concept
The Auto Start/Stop function helps save fuel.
The system switches off the engine during a
stop, for instance in congestion or at traffic
lights. The ignition remains switched on. The
engine starts automatically when you wish to
drive away.
Certain vehicle components may experience
additional wear as a result of this system.
Automatic operation
The automatic engine Start/Stop function is op‐
erational after each engine start.
The function is activated at a certain speed:
▷Automatic transmission: at 5 mph/9 km/h.
Automatic engine stop
The engine is switched off automatically during
a stop under the following conditions:
Automatic transmission:
▷The selector lever is in transmission position
D.▷The brake pedal remains depressed while
the vehicle is at a standstill.▷The driver's safety belt is fastened or the
driver's door is closed.
When the engine is switched off, the air volume
of the automatic climate control is reduced.
Indicator lamp in the instrument cluster The indicator lamp lights up when the
Auto Start/Stop function is ready to
start the engine automatically.
The indicator lamp lights up if the re‐
quirements for an automatic engine
stop are not fulfilled.
Note
The engine is not switched off automatically in
the following situations:
▷External temperatures below ap‐
prox. 37 ℉/+3 ℃.▷High external temperature and operation of
the automatic climate control.▷The interior is not yet heated or cooled as
much as desired.▷The engine is not yet at operating tempera‐
ture.▷Sharp steering angle or the steering wheel
is being turned.▷After driving in reverse.▷Fogging of the windows when the automatic
climate control is switched on.▷Vehicle battery charge is very low.▷Hood is unlocked.▷HDC is activated.▷Stop-and-go traffic.▷The selector lever is in position N or S/M.

ped engine still starts automatically in the fol‐
lowing situations:
▷The interior has heated up strongly with the
cooling function switched on.▷The steering wheel is turned.▷The vehicle begins to roll.▷Automatic transmission: the transmission
position is changed from D to N, R or M/S.▷Automatic transmission: the transmission
position is changed from P to N, D, R or M/
S.▷Fogging of the windows when the automatic
climate control is switched on.▷Vehicle battery charge is very low.▷The interior has cooled down strongly with
the heating switched on.▷Low braking pressure, such as from de‐
pressing the brake pedal a number of times
consecutively.
Preventing automatic engine stop with
an automatic transmission
The concept
To permit the driver to drive away especially
quickly, such as at intersections, the automatic
engine stop can be actively prevented.
Preventing the engine stop using the
brake pedal
The engine stop can be actively prevented
within one second after the vehicle comes to a
standstill.
▷Depress the brake pedal briefly and force‐
fully immediately after the vehicle comes to
a standstill.▷Then continue depressing the brake pedal
with normal braking force.Seite 57DrivingControls57

lever.
Notes Using the handbrake while driving
If it should become necessary to use the
handbrake while driving, do not pull the hand‐
brake too forcefully. Keep the button on the
handbrake lever pressed at all times.
Excessive application of the handbrake can
block the rear wheels and lead to fishtailing of
the vehicle.◀
To prevent corrosion and uneven brake action,
lightly apply the handbrake from time to time
when coasting, traffic conditions permitting.
The brake lamps do not light up when the hand‐
brake is pulled.

the headlamps are cleaned at regular and ap‐
propriate intervals.
Do not use the washer system at freezing
temperatures
Do not use the washers if there is any danger
that the fluid will freeze on the windshield; oth‐
erwise, your vision could be obscured. For this
reason, use antifreeze.
Avoid using the washer when the reservoir is
empty; otherwise, you could damage the
pump.◀
Windshield washer nozzles
