DrivingVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Start/Stop button, drive readiness
The concept The following ready states can
be attained by pressing the
Start/Stop button:▷Radio ready state on/off.▷Ignition on/off.▷Activating/deactivating drive readiness.
To activate drive readiness, press the brake
pedal.
Switching radio-ready state on/off
The radio-ready state is activated by pressing
the Start/Stop button in the following situa‐
tions:
▷When the engine is running.▷When drive readiness is activated.▷When the engine is switched off automati‐
cally using the Auto Start/Stop function
and the brake is not applied.
Some electronic systems/power consumers
remain ready for operation.
Radio ready state is switched off automatically:
▷After approx. 8 minutes.▷When the vehicle is locked using the cen‐
tral locking system.▷Shortly before the battery is discharged
completely, so that the engine can still be
started.
If the engine is switched off and the ignition is
switched on, the system automatically
switches to the radio-ready state if the lights
are turned off or, if correspondingly equipped,
the daytime running lights are activated.
Ignition on Press the Start/Stop button, and do not press
on the brake pedal at the same time.
All vehicle systems are ready for operation.
Most of the indicator and warning lights in the
instrument cluster light up for a varied length
of time.
To save battery power when the engine is off,
switch off the ignition and any unnecessary
electronic systems/power consumers.
Ignition offPress the Start/Stop button again without
stepping on the brake.
All indicator lights in the instrument cluster go
out.
To save battery power when the engine is off,
switch off the ignition and any unnecessary
electronic systems/power consumers.
P when the ignition is switched off
P is engaged automatically when the ig‐
nition is switched off. When in an automatic car
wash, e.g., ensure that the ignition is not
switched off accidentally.◀
The ignition is switched off automatically in the
following situations while the vehicle is station‐
ary and the engine is off:

Parking brake
Applying The lever automatically engages after being
pulled up.
The indicator lamp lights up red. The
parking brake is set.
Lower lamp: indicator lamp in Canadian
models
Releasing
Raise lever slightly, press the button and guide
the lever down.
Hints Use while driving
On rare occasions if it is necessary to use
the parking brake while driving, do not use ex‐
cessive force when applying it. When using it,
keep the button on the lever depressed.
Otherwise, using excessive force when apply‐
ing the parking brake may cause the rear
wheels to lock, resulting in fishtailing.◀
To prevent corrosion and one-sided brake ac‐
tion, lightly apply the parking brake periodically
while coasting, if traffic conditions permit.
The brake lights will not light up if the parking
brake is set.
Turn signal, high beams,
headlight flasher
Turn signal
Hints Do not adjust the exterior mirrors
Do not adjust the exterior mirror while
driving and when turn signals/hazard warning
flashers are on, or else the additional turn sig‐
nal lights in the exterior mirror are out of posi‐ tion and can't be seen.◀
Using turn signals
Press the lever beyond the resistance point.
To switch off manually, press the lever to the
resistance point.
Unusually rapid flashing of the indicator lamp
indicates that a turn signal bulb has failed.
Triple turn signal activation Press the lever to the resistance point.
The turn signal flashes three times.
The function can be activated or deactivated.
