Vehicle care185Sidelight / daytime running light
In case of defective LEDs, have them replaced by a workshop.
LED headlights Headlights for low and high beam,
sidelights, daytime running lights and turn lights are designed as LEDs and
cannot be changed.
Have lights repaired by a workshop in
case of failure.
Front fog lights
The bulbs are accessible from the
underside of the vehicle.1. Turn the bulb holder anti- clockwise and remove it from the
reflector housing.
2. Disengage the bulb socket from the plug connector by pressing
the retaining lug.
3. Remove and replace the bulb socket with bulb and attach the
plug connector.
4. Insert the bulb socket into the reflector housing by turning
clockwise and engage.
Tail lights
Depending on version, tail lights and
brake lights are designed as LEDs. In case of defective LEDs, have them
replaced by a workshop.
Light assembly in the body
Detaching the light assembly
1. Unscrew the two screws that secure the light assembly.
186Vehicle care
2. Remove the light assembly bypulling it straight back.
3. Remove the bulb socket. a) Version without LED:
Remove the three screws and
take out.
b) Version with LED:
Remove from the light assembly
by turning it anticlockwise.
4. Remove the bulb. a) Version without LED:
Pull and replace.

In left-hand drive vehicles, the fuse
box is located behind a cover in the
glovebox. Open the glovebox and
remove the cover. Remove the
bracket.
208Vehicle care● The vehicles must not come intocontact with each other during
the jump starting process.
● Apply the parking brake, transmission in neutral,
automatic transmission in P.
Open the positive terminal protection
caps of both vehicle batteries.
Lead connection order: 1. Connect the red lead to the positive terminal of the booster
battery.
2. Connect the other end of the red lead to the positive terminal of the
discharged battery.
3. Connect the black lead to the negative terminal of the boosterbattery.
4. Connect the other end of the black
lead to a vehicle grounding point
of your vehicle in the engine
compartment.
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.
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
Wrap a cloth around the tip of a flat
screwdriver to prevent paint damage.
Insert a screwdriver in the slot at the
bottom of the cap. Release the cap by carefully moving the screwdriver
downwards.
The towing eye is stowed with the vehicle tools 3 194.
Vehicle care209
Screw in the towing eye as far as it will
go until it stops in a horizontal
position.
Attach a tow rope – or better still a tow
rod – to the towing eye.
The towing eye must only be used for towing and not for recovering the
vehicle.
Switch on ignition to release steering
wheel lock and to permit operation of
brake lights, horn and windscreen
wiper.
Caution
Deactivate the driver assistance
systems like active emergency
braking 3 147, otherwise the
vehicle may automatically brake during towing.
Switch the selector lever to neutral.
Release the parking brake.
Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
When the engine is not running,
considerably more force is needed to
brake and steer.
To prevent the entry of exhaust gases from the towing vehicle, switch on the
air recirculation and close the
windows.
Vehicles with automatic transmission: The vehicle must be towed facing
forwards, not faster than 80 km/h nor further than 100 km. In all other cases
and when the transmission is
defective, the front axle must be
raised off the ground.
Seek the assistance of a workshop.
After towing, unscrew the towing eye.
Insert cap with the outer flange into
the recess and fix cap by pushing.
Towing another vehicle
Wrap a cloth around the tip of a flat
screwdriver to prevent paint damage.
Insert a screwdriver in the slot at the
bottom of the cap. Release the cap by carefully moving the screwdriver
downwards.
Customer information241Legal requirements for
information disclosure
Insofar as regulatory requirements
exist, manufacturers are strictly
bound to release data stored by the
manufacturer in individual cases to
the extent requested following a
request by state bodies (e.g. during
criminal investigations).
Government agencies are also
authorised, in the context of
applicable law, to read data in
individual cases from vehicles
themselves. Thus information that
may help with the investigation
resolution can possibly be read from
the airbag control unit in the event of
an accident.
Operating data in the vehicle Control units process data for
operation of the vehicle.This data includes, for example:
● 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. 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 where 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 read documents the
technical condition of the vehicle or
