Emergency detection of remote control
It is possible to switch on the ignition or start
the engine in situations such as the following:
▷Interference of radio transmission to re‐
mote control by external sources e.g., by
radio masts.
▷Empty battery in remote control.▷Interference from radio transmissions
through mobile devices in close proximity
to remote control.
▷Interference of radio transmission by a
charging process of a mobile device, for ex‐
ample charging of a mobile phone.
A Check Control message is displayed if an at‐
tempt is made to switch on the ignition or start
the engine.
Starting the engine via emergency
detection of the remote control
Steptronic transmission: if a corresponding
Check Control message appears, hold the re‐
mote control, as shown, against the marked
area on the steering column and press the
Start/Stop button within 10 seconds while
pressing the brake.
Manual transmission: if a corresponding Check
Control message appears, hold the remote con‐
trol, as shown, against the marked area on the

Personal Profile
The concept
Using Personal Profile, individual settings for
several drivers can be saved and called up
again at a later time.
General information
There are three profiles with which personal ve‐
hicle settings can be stored. Every remote con‐
trol has one of these profiles assigned.
If the vehicle is unlocked using a remote con‐
trol, the assigned personal profile will be acti‐
vated. All settings stored in the profile are auto‐
matically applied.
If several drivers use their own remote control,
the vehicle will adjust the personal settings dur‐
ing unlocking. These settings are also restored,
if the vehicle has been used in the meantime
by a person with a different remote control.
Changes to the settings are automatically saved
in the profile currently activated.
If another profile is selected via the onboard
monitor, the settings saved in it will be applied
automatically. The new profile is assigned to
the remote control currently used.
There is an additional profile available that is
not assigned to any remote control: It can be
used to apply settings in the vehicle without
changing the personal profiles.
Adjusting
The settings for the following systems and func‐
tions are saved in the active profile. The scope
of storable settings is country- and equipment-
dependable.
▷Unlocking and locking.▷Lights.▷Radio.▷Instrument cluster.▷Programmable memory buttons.▷Volumes, tone.▷Control Display.▷Climate control.▷Navigation.▷Park Distance Control PDC.▷Rearview camera▷Head-up Display.▷Driving Dynamics Control.▷Intelligent Safety.
Profile management
Opening profiles
Regardless of the remote control in use a differ‐
ent profile may be activated.
On the Control Display:
1. "Settings"2."Profiles"3.Select a profile.
The following functions are executed:
▷All settings stored in the called-up profile
are automatically applied.
▷The called-up profile is assigned to the re‐
mote control being used at the time.
▷If the profile is already assigned to a differ‐
ent remote control, this profile will apply to
both remote controls. It cannot be differen‐
tiated anymore between the settings for
the two remote controls.
Renaming profiles
A personal name can be assigned to every pro‐
file to avoid confusion between the profiles.
On the Control Display:
1. "Settings"2."Profiles"
The current profile is selected.

not hit the rear window.◀
Malfunction
Remote control detection by the vehicle can
among others be malfunctioning under the fol‐
lowing circumstances:

DrivingVehicle features and op‐
tions
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 sys‐
tems. The respectively applicable country provi‐
sions must be observed when using the respec‐
tive features and systems.
Start/Stop button
The concept
Pressing the Start/Stop button
switches the ignition on or off
and starts the engine.
Steptronic transmission: the en‐
gine starts in selector lever posi‐
tion P or N with the brake pedal pressed when
you press the Start/Stop button.
Manual transmission: the engine starts with the
clutch pedal pressed when the Start/Stop but‐
ton is pressed.
Ignition on
Manual transmission: press the Start/Stop but‐
ton without stepping on the clutch pedal.
Steptronic transmission: 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 off
Manual transmission: press the Start/Stop but‐
ton again without stepping on the clutch pedal.
Steptronic transmission: shift to selector lever
position P, press 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.
The ignition is switched off automatically in the
following situations while the vehicle is station‐
ary and the engine is off:
▷During locking, also with the low beams ac‐
tivated.
▷Shortly before the battery is discharged
completely, so that the engine can still be
started. This function is only available when
the low beams are turned off.
▷When opening and closing the driver door,
if the driver's safety belt is unbuckled and
the low beams are turned off.
▷While the driver's safety belt is unbuckled
with driver's door open and low beams off.
▷The low beams switch to parking lights af‐
ter approx. 15 minutes of no use.
Radio ready state
Activate radio-ready state: when the engine is
running: press the Start/Stop button.

cally in the following situations:
Seite 64CONTROLSDriving64
Online Edition for Part no. 01 40 2 964 571 - X/15
▷After approx. 8 minutes.▷When the vehicle is locked using the central
locking system.
▷Shortly before the battery is discharged
completely, so that the engine can still be
started.
The radio-ready state remains active if, for ex‐
ample, the ignition is automatically switched off
for the following reasons:
▷Opening or closing the driver's door.▷Unfastening of the driver's safety belt.▷When automatically switching from low
beams to parking lights.
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 day‐
time running lights are activated.
Starting the engine
Information
DANGER
If the exhaust pipe is blocked or ventila‐
tion is insufficient, harmful exhaust gases can
enter into the vehicle. The exhaust gases con‐
tain carbon monoxide, an odorless and color‐
less but highly toxic gas. In enclosed areas, ex‐
haust gases can also accumulate outside of the
vehicle. There is danger to life. Keep the ex‐
haust pipe free and ensure sufficient ventila‐
tion.◀
WARNING
An unsecured vehicle can put itself into
motion and roll away. There is risk of an acci‐
dent. Before exiting, secure the vehicle against
rolling.
In order to ensure that the vehicle is secured
against rolling away, observe the following:
▷Set the parking brake.▷On uphill grades or on a slope, turn the
front wheels in the direction of the curb.
▷On uphill grades or on a slope, also secure
the vehicle, for example with a wheel
chock.◀
CAUTION
In the case of repeated starting attempts
or repeated starting in quick succession, the
fuel is not burned or is inadequately burned.
The catalytic converter can overheat. There is
risk of property damage. Avoid repeated start‐
ing in quick succession.◀
