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
Do not leave the car unattended with the
engine running; otherwise, it presents a poten‐
tial source of danger.
Before leaving the car with the engine running,
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.

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.

Servotronic
The concept
The Servotronic varies the steering force re‐
quired to turn the wheels depending on the
speed at which you are driving.
Power steering provides strong support at low
speeds, which means that less effort is needed
to turn the wheels. Power steering support less‐
ens as your speed increases.
Malfunction The warning lamp lights up.A mes‐
sage appears on the Control Display.
Servotronic is malfunctioning or has
failed. Have the system checked as soon as pos‐
