222Vehicle careElectrical systemHigh voltage devices andwiring9 Warning
Exposure to high voltage may
cause shock, burns, and even
death. The high voltage
components in the vehicle should
only be serviced by specially
trained technicians.
High voltage components are
identified by labels. Do not
remove, open, take apart, or
modify these components. High
voltage cable or wiring has orange covering. Do not probe, tamper
with, cut, or modify high voltage
cable or wiring.
Electrical system overload
The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
If the current electrical load is too
heavy, the circuit breaker will open
and close, protecting the circuit until
the current load returns to normal or the problem is fixed. This greatly
reduces the chance of circuit
overload and fire caused by electrical
problems.
Fuses and circuit breakers protect the
following parts in the vehicle:
● Headlight wiring
● Windscreen wiper motor
● Power windows and other power accessories
Headlight wiring An electrical overload may cause the
lights to go on and off or in some
cases to remain off. In this case, have
the headlight wiring checked
immediately by a workshop.
Windscreen wipers
If the wiper motor overheats due to
blockage from heavy snow or ice, the windscreen wipers will stop until themotor has cooled down and the wiper
control has been turned off. Afterremoval of the blockage, the wiper
motor will restart when moving the
wiper control to the desired operating
position.
Although the circuit is protected from
electrical overload, mechanical
overload due to heavy snow or ice
may cause wiper linkage damage.
Always clear ice and heavy snow
from the windscreen before using the windscreen wipers. If the overload is
caused by an electrical problem and
not snow or ice, it must be serviced.
Fuses
Data on the replacement fuse must match the data on the defective fuse.
There are two fuse boxes in the
vehicle:
● at the front left side of the engine
compartment
● at the left side of the instrument panel
Before replacing a fuse, turn off the
respective switch and the vehicle.
Vehicle care241Battery terminals in the engine
compartment
The battery terminals to jump start the
vehicle are located in the engine
compartment.
The positive battery terminal is
located below a cover. Open the
cover before jump starting the
vehicle.
The negative battery terminal is stud
on a bracket located near the charger
modules.
Jump starting the vehicle
Lead connection order:
1. Connect the red lead to the positive terminal of the booster
vehicle battery.
2. Connect the other end of the red lead to the positive terminal of
your vehicle.
3. Connect the black lead to the negative terminal of the booster
vehicle battery.
4. Connect the other end of the black
lead to the negative battery
terminal (stud).
Route the leads so that they cannot
catch on rotating parts in the engine
compartment.
To start the vehicle: 1. Start the engine of the vehicle providing the jump.
2. After 5 minutes, press POWERm
to switch on the vehicle.
After the instrument cluster
initialises, the vehicle will use
power from the high voltage
battery to charge the 12 V vehicle
battery.
3. Switch on electrical consumers (e.g. headlights, heated rear
window) of the vehicle receiving
the jump start.
4. Reverse above sequence exactly when removing leads.
242Vehicle careTowingTowing the vehicleCaution
Incorrect towing of a disabled
vehicle may cause damage to the
vehicle. The disabled vehicle
should only be towed on a flatbed
car carrier.
Ensure the vehicle is only towed
by well trained technicians.
Wrap a cloth around the tip of a slot
screwdriver to prevent paint damage. Insert the screwdriver in the slot at the
short edge of the cap. Release the
cap by carefully moving the
screwdriver sidewards.
The towing eye is stowed with the vehicle tools 3 230.
Screw in the towing eye anticlockwise
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 the vehicle 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 3 168, otherwise the
vehicle may automatically brake during towing.
Shift the selector lever of the electric
drive unit into N.
Release the electric parking brake.
Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
When the vehicle is not running, considerably more force is needed to
brake and steer.
244Vehicle careDo not clean the engine compartmentwith a steam-jet or high-pressure jet
cleaner.
Thoroughly rinse and leather-off the
vehicle. Rinse leather frequently. Use
separate leathers for painted and
glass surfaces: remnants of wax on
the windows will impair vision.
Have the door hinges of all doors
greased by a workshop.
Do not use hard objects to remove
spots of tar. Use tar removal spray on painted surfaces.
Exterior lights
Headlight and other light covers are
made of plastic. Do not use any
abrasive or caustic agents, do not use an ice scraper, and do not clean them
dry.
Polishing and waxing
Wax the vehicle regularly (at the
latest when water no longer beads).
Otherwise, the paintwork will dry out.
Polishing is necessary only if the paint
has become dull or if solid deposits
have become attached to it.Paintwork polish with silicone forms a
protective film, making waxing
unnecessary.
Plastic body parts must not be treated with wax or polishing agents.
Windows and wiper blades Switch off wipers before handling in
their areas.
Use a soft lint-free cloth or chamois leather together with window cleanerand insect remover.
When cleaning the rear window from
inside, always wipe in parallel to the
heating element to prevent damage.
For mechanical removal of ice, use a
sharp-edged ice scraper. Press the
scraper firmly against the glass so
that no dirt can get under it and
scratch the glass.
Remove dirt residues from smearing
wiper blades by using a soft cloth and window cleaner. Also make sure to
remove any residues such as wax,
insect residues and similar from the
window.Ice residues, pollution and continuous
wiping on dry windows will damage or
even destroy the wiper blades.
Wheels and tyres Do not use high-pressure jet
cleaners.
Clean rims with a pH-neutral wheel
cleaner.
Rims are painted and can be treated
with the same agents as the body.
Paintwork damage
Rectify minor paintwork damage with
a touch-up pen before rust forms.
Have more extensive damage or rust areas repaired by a workshop.
Underbody
Some areas of the vehicle underbody
have a PVC undercoating while other critical areas have a durable
protective wax coating.
After the underbody is washed, check
the underbody and have it waxed if
necessary.
Customer information259Operating 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.
