by local radio waves, such as by a mobile phone
in the immediate vicinity of the remote control or
when a mobile phone is being charged in the
vehicle.
If this occurs, open or close the vehicle using the
buttons on the remote control or use the
integrated key in the door lock.
To start the engine afterward, insert the remote
control into the ignition switch.
Warning lamps The warning lamp in the instrument
cluster lights up when you attempt to
start the engine: the engine cannot be
started.
The remote control is not in the vehicle or has a
malfunction. Take the remote control with you
inside the vehicle or have it checked. If neces‐
sary, insert another remote control into the ig‐
nition switch.
The warning lamp in the instrument
cluster lights up while the engine is
running: the remote control is no lon‐
ger inside the vehicle.
After switching off the engine, the engine can
only be started again within approx. 10 seconds
if no door has been opened.

tains a battery that will need to be replaced from
time to time.1.Take the integrated key out of the remote
control, refer to page 30.2.Remove the cover.3.Insert a new battery of the same type with
the positive side facing upwards.4.Press the cover closed.
Return used battery to a recycling collec‐
tion point or to your service center.
Alarm system
The concept
The vehicle alarm system responds to:
▷Opening of a door, the hood or the tailgate.▷Movements in the vehicle: interior motion
sensor, refer to page 39.▷Changes in the vehicle tilt, e.g., during at‐
tempts to steal a wheel or tow the car.▷Interruptions in battery voltage.

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

Operational readiness of airbag system
When the ignition is switched on,, refer
to page 54, the warning lamp comes on
briefly to indicate that the entire airbag
system and the belt tensioners are operational.
Airbag system malfunction
▷The warning lamp does not light up after the
ignition is switched on.▷Warning lamp remains permanently on.
Have the airbag system checked without
delay if there is a malfunction
In the event of a malfunction in the airbag sys‐
tem, have it checked without delay; otherwise,
there is the risk that the system will not function
as intended even if a sufficiently severe accident
occurs.◀
FTM Flat Tire Monitor
The concept
The system does not measure the actual infla‐
tion pressure in the tires.
It detects a pressure loss in a tire by comparing
the rotational speeds of the individual wheels
while moving.
In the event of a pressure loss, the diameter and
therefore the rotational speed of the corre‐
sponding wheel change. This is detected and
reported as a flat tire.
Functional requirements
The system must have been initialized when the
tire inflation pressure was correct; otherwise,
reliable signaling of a flat tire is not ensured. In‐
itialize the system after each correction of the
tire inflation pressure and after every tire or
wheel change.
System limits Sudden tire damage
Sudden serious tire damage caused by
external influences cannot be indicated in ad‐
vance.◀
A natural, even pressure loss in all four tires can‐
not be detected. Therefore, check the tire infla‐
tion pressure regularly.
The system could be delayed or malfunction in
the following situations:▷When the system has not been initialized.▷When driving on a snowy or slippery road
surface.▷Sporty driving style: slip in the drive wheels,
high lateral acceleration.▷When driving with snow chains.
Status display
The current status of the Flat Tire Monitor can
be displayed on the Control Display, e.g.,
whether or not the FTM is active.
1."Vehicle Info"2."Vehicle status"3. "Flat Tire Monitor"
The status is displayed.
Initialization
The initialization process adopts the set inflation
tire pressures as reference values for the detec‐
tion of a flat tire. Initialization is started by con‐
firming the inflation pressures.

Final tire failure
Vibrations or loud noises while driving can
indicate the final failure of the tire. Reduce speed
and stop; otherwise, pieces of the tire could
come loose and cause an accident. Do not con‐
tinue driving, and contact your service center. ◀
Tire Pressure Monitor TPM
The concept
The tire inflation pressure is measured in the
four mounted tires. The system notifies you if
there is a significant loss of pressure in one or
more tires.
Functional requirements
The system must have been reset while the in‐
flation pressure was correct; otherwise, reliable
signaling of a flat tire is not ensured.
Always use wheels with TPM electronics to en‐
sure that the system will operate properly.
Reset the system after each correction of the
tire inflation pressure and after every tire or
wheel change.
System limits Sudden tire damage
Sudden serious tire damage caused by
external influences cannot be indicated in ad‐
vance.◀
The system does not operate correctly if it has
not been reset. For example, a flat tire may be
indicated despite correct tire inflation pres‐
sures.
The system is inactive and cannot indicate a flat
tire:▷For a mounted wheel without TPM electron‐
ics.▷When the TPM is disturbed by other sys‐
tems or devices with the same radio fre‐
quency.Status display1."Vehicle Info"2."Vehicle status"3. "TPM"
The status is displayed.
Status indicator on the Control Display
The tire and system status is indicated by the
color of the tires.
A change in the tire inflation pressure during
driving is taken into account.
A correction is only necessary if this is indicated
by the TPM
Wheels, green
The tire inflation pressure is equal to the target
state.
One wheel is yellow
A flat tire or major drop in inflation pressure in
the indicated tire.
All wheels are yellow
▷A flat tire or major drop in inflation pressure
in several tires.▷The system was not reset after a wheel
change and thus issues a warning based on
the inflation pressures initialized last.▷A flat tire in one or more tires while the sys‐
tem is being reset.
Wheels, gray
The system cannot detect a flat tire.
Reasons for this may be:
▷TPM is being reset.▷Disturbance by systems or devices with the
same radio frequency.▷Malfunction.Seite 90ControlsSafety90
