Additional air conditioning is supplied to the rear passenger compartment
via the air vents located above the
driver and front passenger
compartment.
With the front passenger
compartment air conditioning system
switched on, adjust the air flow to
select the desired speed.
Ensure the air vents are open when in use, to prevent ice forming in the
system due to lack of air movement.
Auxiliary heater Coolant heater
The engine-independent, fuel-
powered coolant heater provides rapid heating of the engine coolant to
enable heating of the vehicle interior
without the engine running.
Note
Depending on version, an additional
coolant heater may be switched on
automatically to speed up heating
when the ignition is on and the
outside temperature is below 5 ℃.9 Warning
Do not operate the system when
refuelling, when dust or
combustible vapours are present
or in enclosed spaces (e.g.
garage).
Before starting or programming the
system to start, turn the vehicle's
climate control system to heat, set the
air distribution to V and turn the fan
on.
Switch off when not required. Heating stops automatically after the
programmed runtime. It will also
cease to operate if the vehicle fuel
level drops too low.
During operation, power from the
vehicle battery is used. The driving
time should therefore be at least as
long as the heating time. For short
journey times, check the vehicle
battery regularly and recharge if
necessary.
To ensure efficient performance,
briefly operate the auxiliary heater
once a month.

Climate control219Depending on version, the auxiliary
heater can also be switched on for the
last duration time or the default
duration 30 minutes, or cut-off
immediately, using the button on the
instrument panel. The LED in the
button confirms operation.
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:
2CR 11108, or equivalent), ensuring
the new battery is correctly installed
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.

Driving and operating251Increase speedWith cruise control active, the vehicle
speed can be increased continuously or in small increments by holding
down or tapping < repeatedly.
When the switch is released the
current speed is stored and
maintained.
Alternatively, accelerate to the
desired speed and store by pressing
< .
Reduce speed With cruise control active, the vehicle
speed can be decreased
continuously or in small increments
by holding down or tapping ]
repeatedly.
When the switch is released the
current speed is stored and
maintained.Deactivation of the functionality
Press $: cruise control is deactivated
and the green control indicator m
extinguishes in the instrument cluster.
Automatic deactivation: ● vehicle speed drops below 30 km/h
● the brake pedal is depressed
● the clutch pedal is depressed
● selector lever in N
The speed is stored and a
corresponding message appears in
the Driver Information Centre.
Activation 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

cluster.
Speed limiter
The speed limiter prevents the
vehicle exceeding a preset maximum
speed above 30 km/h.

324Customer informationOperating data in the vehicleControl units process data for
operation of the vehicle.
This data includes, e.g.: ● vehicle status information (e.g. speed, movement delay, lateral
acceleration, wheel rotation rate, "seat belts fastened" display)
● ambient conditions (e.g. temperature, rain sensor,
distance sensor)
As a rule such data is transient, not
stored for longer than an operational
cycle, and only processed on board the vehicle itself. Control units often
include data storage (including 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.Depending on technical equipment
level, the data stored is as follows:
● system component operating states (e.g. fill level, tyre
pressure, battery status)
● faults and defects in important system components (e.g. lights,
brakes)
● system reactions in special driving situations (e.g. triggering
of an airbag, actuation of the
stability control systems)
● information on events damaging the vehicle
● for electric vehicles the amount of
charge in the high-voltage
battery, estimated range
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 (e.g. repairs,
maintenance), the operating data
saved can be read together with the
vehicle identification number and
used when necessary. Staff working
for the service network ( e.g. garages,
manufacturers) or third parties (e.g.breakdown services) can read the
data from the vehicle. The same
applies to warranty work 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 is read out,
documents the technical condition of
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 uses operating data
from vehicles for product recalls. This
data can also be used to check
customer warranty and guarantee
claims.
Fault memories in the vehicle can be
reset by a service company when
carrying out servicing or repairs or at
your request.
