When refuelling, switch off the
remote control unit as well as the
heater!
The remote control has a maximum
range of 1000 m. The range may be
reduced due to environmental
conditions and as the battery
becomes weaker.

Battery replacement
Replace the battery when the range
of the remote control is reduced or
when the battery charge symbol
flashes.
Open the cover and replace the
battery (Type A: CR 2430, Type B:

with the positive ( <) side facing the
positive terminals. Replace the cover
securely.
Dispose of old batteries in
accordance with environmental
regulations.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.

166Driving and operatingActivation of the functionality
Press R at a speed above 30 km/h.
If the stored speed is much higher
than the current speed, the vehicle
will accelerate powerfully until the
stored speed is obtained.
Pressing < will also reactivate the
cruise control function, but at the
current vehicle speed only, not the
stored speed.
Switching off the system
Press m, green control indicators U
and m extinguish in the instrument
cluster.
Speed limiter
The speed limiter prevents the
vehicle exceeding a preset maximum
speed above 30 km/h.Switching on the system
Press U, control indicator U
illuminates yellow in the instrument
cluster.
Speed limiter function is now in
standby mode and a corresponding
message appears in the Driver
Information Centre.
Accelerate to the desired speed and
press < or ]. The current speed is
recorded.
The vehicle can be driven normally
but it will not be possible to exceed the programmed speed limit except in an
emergency.
Where the limit speed cannot be
maintained, e.g. when driving on a
steep decline, the limit speed will
flash in the Driver Information Centre.
Increase limit speed
The limit speed can be increased
continuously or in small increments
by holding down or tapping <
repeatedly.
Reduce limit speed
The limit speed can be decreased continuously or in small increments
by holding down or tapping ]
repeatedly.
Exceeding the limit speed
In the event of an emergency it is
possible to exceed the limit speed by
depressing the accelerator pedal
firmly beyond the point of resistance.
The limit speed will flash in the Driver
Information Centre during this period.
Release the accelerator pedal andthe speed limiter function is
reactivated once a speed lower than
the limit speed is obtained.
Customer information259This data includes, for example:● Vehicle status information (e.g. wheel rotation rate, speed,
movement delay, lateral
acceleration, "seatbelts
fastened" display),
● Ambient conditions (e.g. temperature, rain sensor,
distance sensor).
Most of this data is volatile and is processed only in the vehicle itself,and not beyond the operating time.
Moreover, many control units include
data storage device (amongst others the vehicle key). This is used to allow
information to be documented
temporarily or permanently on vehicle
condition, component stress,
maintenance requirements and
technical events and errors.
The following information, for
example, is stored:
● System component operating states (e.g. fill level, tyre
pressure, battery status),
● State of charge of the high voltage battery, estimated range
(in the case of electric vehicles),● Faults and defects in important system components (e.g. lights,
brakes),
● System reactions in special driving situations (e.g. triggeringof an airbag, actuation of the
stability control systems),
● Information on events damaging the vehicle.
In special cases (e.g. if the vehicle
has detected a malfunction), it may be
necessary to save data that would
otherwise just be volatile.
When you use services, the operating data saved can be read together withthe vehicle identification number andused if necessary. Staff working for
the service net-work (e.g. garages,
manufacturers) or third parties (e.g.
breakdown services) can read the
data from the vehicle. Services
include repair services, maintenance
processes, warranty cases and
quality assurance measures.
Data is generally read via the OBD
(On-Board Diagnostics) port
prescribed by law in the vehicle. The operating data which has been read
out documents the technical conditionof the vehicle or individual
components and assists with fault
diagnosis, compliance with warranty
obligations and quality improvement.
This data, in particular information on
component stress, technical events,
operator errors and other faults, is
transmitted to the manufacturer
where appropriate, together with the vehicle identification number. The
manufacturer is also subject to
product liability. The manufacturer
potentially also needs operating data
from vehicles for product recalls.
Fault memories in the vehicle can be
reset by a service company when
carrying out servicing or repairs.
Comfort and infotainment
functions
Comfort settings and custom settings can be stored in the vehicle and
changed at any time.
