socket.
For this type, the red < and
black ] power supply leads will not
be present.
To avoid discharging the battery,
we recommend running the
engine.
11. Set the rocker switch on the compressor to position I. The tyre
is filled with sealant.
12. The compressor pressure gauge briefly indicates up to 6 bar. Then
the pressure starts to drop.
13. All of the sealant is pumped into the tyre. Then the tyre is inflated.
304Vehicle careThe following applies to tyres fitted
opposing the rolling direction:
● Driveability may be affected. Have the defective tyre renewed
or repaired as soon as possible
and fit it instead of the spare
wheel.
● Do not drive faster than 80 km/h.
● Drive particularly carefully on wet
and snow-covered road
surfaces.Jump starting
The jump start terminal is located in
the engine compartment.
A vehicle with a discharged vehicle
battery can be started using jump
leads and the vehicle battery of
another vehicle.
Do not start with a quick charger.9 Warning
Be extremely careful when starting
with jump leads. Any deviation
from the following instructions can
lead to injuries or damage caused
by battery explosion or damage to the electrical systems of both
vehicles.
9 Warning
Avoid contact of the battery with
eyes, skin, fabrics and painted
surfaces. The fluid contains
sulphuric acid which can cause
injuries and damage in the event
of direct contact.
Caution
The air suspension system must
be switched off prior to jump
starting.
Air suspension 3 231.
● Never expose the vehicle battery
to naked flames or sparks.
● A discharged vehicle battery can already freeze at a temperature
of 0 °C. Defrost the frozen vehicle
battery before connecting jump leads.
● Wear eye protection and protective clothing when
handling a vehicle battery.
● Use a booster battery with the same voltage (12 V). Its capacity(Ah) must not be much less than
that of the discharged vehicle
battery.
● Use jump leads with insulated terminals and a cross section of
at least 25 mm 2
.
● Do not disconnect the discharged
battery from the vehicle.
Vehicle care305● Switch off all unnecessaryelectrical consumers.
● Switch off the air suspension system 3 231.
● Do not lean over the vehicle battery during jump starting.
● Do not allow the terminals of one
lead to touch those of the other
lead.
● The vehicles must not come into contact with each other during
the jump starting process.
● Apply the parking brake and engage neutral (manual
transmission) or N (manual
transmission automated).Jump start terminal
In the event of a discharged vehicle
battery, the jump start terminal
enables the vehicle to be started
without the need to access the battery inside the vehicle.
The jump start terminal is located in
the engine compartment and
identified by a " <" sign on the red
insulating cover. Lift the red insulating
cover to access the terminal
connector.
Ensure the red insulating cover is
latched back into position when not in
use.
Jump starting procedure
Depending on model, the jump start
terminal may be located at the left-
hand or right-hand side of the engine
compartment.
306Vehicle care
Lead connection order:1. Connect the red lead to the positive terminal (1) of the booster
battery.
2. Connect the other end of the red lead to the jump start terminal (2)
of the vehicle with the discharged
vehicle battery.
3. Connect the black lead to the negative terminal (3) of the
booster battery.
4. Connect the other end of the black
lead to a vehicle grounding point
(4), such as the engine block or an
engine mounting bolt. Connect as
far away from the discharged
vehicle battery as possible,
however at least 60 cm.
Route the leads so that they cannot
catch on rotating parts in the engine
compartment.
To start the engine: 1. Start the engine of the vehicle providing the jump start.
2. After 5 minutes, start the other engine. Start attempts should be
made for no longer than
15 seconds at an interval of
1 minute.
3. Allow both engines to idle for approx. 3 minutes with the leads
connected.
4. Switch on electrical consumers (e.g. headlights, heated rear
window) of the vehicle receiving
the jump start.
5. Reverse above sequence exactly when removing leads.Towing
Towing the vehicle The towing eye and wheel wrench are
stowed with the vehicle tools 3 290.
Disengage the cover using a suitable
tool and remove.
Screw the towing eye clockwise into
the front towing point and tighten fully using the wheel wrench.
Attach a tow rope – or better still a tow
rod – to the towing eye, never to the
bumper or front suspension units.
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.
