180Vehicle careWhen the vehicle battery is beingreplaced, ensure that there are no
open ventilation holes in the vicinity of
the positive terminal. If a ventilation
hole is open in this area, it must be
closed off with a dummy cap, and the ventilation in the vicinity of the
negative terminal must be opened.
Ensure that the vehicle battery is
always replaced by the same type of
battery.
The vehicle battery has to be
replaced by a workshop.
Stop-start system 3 126.
Charging the vehicle battery9 Warning
On vehicles with stop-start
system, ensure that the charging potential does not exceed 14.6 V
when using a battery charger.
Otherwise the vehicle battery may
be damaged.
Jump starting 3 208.
Discharge protection
Battery voltage
When the vehicle battery voltage is
running low, a warning message will
appear in the Driver Information
Centre.
When the vehicle is being driven, the
load reduction function temporarily
deactivates certain functions, e.g. the
heated rear window.
The deactivated functions are
reactivated automatically as soon as
conditions permit.
Idle boost
If charging of the vehicle battery is
required due to battery condition, the
power output of the generator must
be increased. This will be achieved by an idle boost which may be audible.
A message appears in the Driver
Information Centre.
Power outlet
The power outlets are deactivated in
the event of low vehicle battery
voltage.Warning label
Meaning of symbols:
● No sparks, naked flames or smoking.
● Always shield eyes. Explosive gases can cause blindness or
injury.
● Keep the vehicle battery out of reach of children.
● The vehicle battery contains sulphuric acid which could cause
blindness or serious burn
injuries.
Vehicle care197The tyre pressure information label
on the left door frame indicates the
original equipment tyres and the
correspondent tyre pressures.
The tyre pressure data refers to cold
tyres. It applies to summer and winter
tyres.
Always inflate the spare tyre to the
pressure specified for full load.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and fuel economy and will increase tyre
wear.
The tyre pressure table indicates the
required pressure for a specific tyre
size only and shows all possible tyre
combinations 3 229.
For the tyres approved for this
vehicle, refer to the EEC Certificate of Conformity provided with the vehicle
or other national registration
documents.
The driver is responsible for correct adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
9 Warning
For specific tyres the
recommended tyre pressure as
shown in the tyre pressure table may exceed the maximum tyre
pressure as indicated on the tyre.
Never exceed the maximum tyre
pressure as indicated on the tyre.
Temperature dependency
The tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase. Tyre pressure
values provided on the tyre
information label and tyre pressure
chart are valid for cold tyres, which means at 20 °C.
The pressure increases by nearly
1.5 psi for a 10 °C temperature
increase. This must be considered
when warm tyres are checked.
Tyre deflation detectionsystem
The tyre deflation detection system
continually checks the rotation speed
of all four wheels and warns on low
tyre pressure condition once vehicle
is driving. This is achieved by
comparing tyre rolling circumference
with reference values and further
signals.
If a tyre loses pressure the control
indicator w illuminates and a warning
message is displayed in the Driver Information Centre.
In this case reduce speed, avoid
sharp cornering and strong braking.
Stop at next safe opportunity and
check tyre pressure.
Control indicator w 3 86.
After adjusting tyre pressure initialise
system to extinguish the control
indicator and restart system.
198Vehicle careCaution
Deflation detection system warns
just about low tyre pressure
condition and does not replace
regular tyre maintenance by the
driver.
In case of a system malfunction a
message is displayed in the Driver
Information Centre. Set correct tyre
pressure and reinitialise system. If the
failure continues to be displayed,
contact a workshop. The system is
inoperable when ABS or ESC has a
malfunction or a temporary spare
wheel is used.
In case of a system malfunction a
message is displayed in the Driver
Information Centre. Set correct tyre
pressure and reinitialise system. If the
failure continues to be displayed,
contact a workshop. The system is
inoperable when ABS or ESC has a
malfunction.
Once the road tyre has been refitted,
check the tyre pressure with cold
tyres and initialise the system.
System initialisation
After tyre pressure correction or
wheel change, the system must be
initialised to learn new circumference reference values:
1. Always ensure that all four tyres have correct tyre pressure3 229.
2. Apply parking brake. 3. Press w to reset deflation
detection system.
4. Reset is confirmed by pop-up indication.
After initialisation system
automatically calibrates to new tyre
pressures during driving. After longer
drive the system will adopt and
monitor new pressures.
Always check tyre pressure with cold
tyres.
System has to be reinitialised when: ● tyre pressure has been changed
● load condition has been changed
● wheels have been swapped or exchanged
The system will not warn
instantaneously on a tyre blow out or
a rapid deflation. This is due to
required calculation time.
Tread depthCheck tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
For safety reasons, it is
recommended that the tread depth of the tyres on one axle should not vary
by more than 2 mm.
Vehicle care205There is a box with tools in the
right wall of the load compartment.
Vehicle tools 3 195.
3. When, after a wheel change, no wheel is placed in the spare wheelwell, fasten the wing nut and close
the floor cover.
4. After a wheel change back to a full
size wheel, place the spare wheel
outside up in the well and secure
with the wing nut.
Temporary spare wheelCaution
If driving with a temporary spare
wheel, active emergency braking
has to deactivated.
Only mount one temporary spare
wheel. The permissible maximum
speed on the label on the temporary
spare wheel is only valid for the
factory-fitted tyre size.
Do not drive faster than 50 mph. Take curves slowly. Do not use for a long
period of time.
Fitting the spare wheel
Make the preparations given for
wheel changing 3 203 and observe
the following information:
● Never change more than one wheel at once.
● Use the jack only to change wheels in case of puncture, not
for seasonal winter or summer
tyre change.
● The jack is maintenance-free.
1. Disengage wheel bolt caps with a
screwdriver and remove.
Steel wheels with cover: Pull off
the wheel cover.
Alloy wheels: Disengage wheel
bolt caps with a screwdriver and
remove. To protect the wheel,
place a soft cloth between the
screwdriver and the alloy wheel.
2. Fold out the wheel wrench and install ensuring that it locates
securely and loosen each wheel
bolt by half a turn.
The wheels might be protected by
locking wheel bolts. To loosen
these specific bolts, first attach
the adapter for the locking wheel
bolts onto the head of the bolt
before installing the wheel
wrench. The adapter is located in
the glovebox or in the load
compartment under the rear floor
cover.
234Customer informationVehicle data recording
and privacy
Event data recorders
Electronic control units are installed in
your vehicle. Control units process
data which is received e.g. by vehicle sensors, or which they generate
themselves or exchange amongst
themselves. Some control units are
necessary for the safe functioning of
your vehicle, others assist you while
you drive (driver assistance systems),
while others provide comfort or
infotainment functions.
The following contains general
information about data processing in
the vehicle. You will find additional
information as to which specific data
is uploaded, stored and passed on to third parties and for what purpose in
your vehicle under the key word Data Protection closely linked to the
references for the affected functional
characteristics in the relevant
Owner's Manual or in the general
terms of sale. These are also
available online.Operating data in the vehicle
Control units process data for
operation of the vehicle.
This data may include: ● 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 and is
not stored for longer than an
operational cycle, and only processed
on board the vehicle itself. Often
control units 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
levels, 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. triggeringof 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 where necessary. Staff working
for the service network ( e.g. garages,
manufacturers) or third parties (e.g.
