Vehicle care211Lifting the vehicle9Warning
Lifting the vehicle improperly can
cause serious injuries and
damage to the vehicle.
The vehicle should be lifted only by well-trained staff at an
authorised workshop.
Jacking position for lifting platform
Rear arm position of the lifting
platform at the underbody.
Front arm position of the lifting
platform at the underbody.
Ramps may be needed under the
front tyres to provide the necessary
clearance for certain lifting platforms
in this location.
Vehicle storage Storage for a long period of timeIf the vehicle is to be stored for several months:
● Wash and wax the vehicle.
● Have the wax in the engine compartment and underbody
checked.
● Clean and preserve the rubber seals.
● Drain the washer fluid reservoir.
● Check the coolant antifreeze and
corrosion protection.
● Adjust tyre pressure to the value specified for full load.
● Park the vehicle in a dry, well ventilated place. Engage P.
Prevent the vehicle from rolling.
● Do not apply the parking brake.
● Open the bonnet, close all doors and lock the vehicle.Up to four weeks
Plug in the charge cord.Four weeks to twelve months ● Discharge the high voltage battery until two or three bars
remain on the battery range
indicator (battery symbol) on the
instrument cluster.
● Do not plug in the charge cord.
● Always store the vehicle in a place with temperatures between−10 °C and 30 °C.
212Vehicle care● Vehicle storage at extremetemperatures may cause
damage to the high voltage
battery.
● Remove the black negative (−) cable from the 12 V vehicle
battery and attach a trickle
charger to the vehicle battery
terminals or keep the 12 V
vehicle battery cables connected and trickle charge from the
positive (+) and negative (−)
terminals in the engine
compartment.Caution
The vehicle is equipped with an
AGM 12 V vehicle battery, which
can be damaged by using the
incorrect type of trickle charger.
An AGM compatible charger must be used with the appropriate
setting selected.
Follow the trickle charger
manufacturer instructions.
After the 12 V vehicle battery cable is reconnected, it is possible that the
vehicle may not operate. If this
happens, the high voltage battery
may need to be charged.
Putting back into operation
When the vehicle is to be put back into operation:
● Connect the clamp to the negative terminal of the 12 V
vehicle battery. Activate the
electronics of the power
windows.
● Check tyre pressure.
● Fill up the washer fluid reservoir.
● Check the coolant level.
● Fit the number plate if necessary.
End-of-life vehicle recovery
Information on end-of-life vehicle
recovery centres and the recycling of
end-of-life vehicles is available on our website, where legally required. Only
entrust this work to an authorised
recycling centre.Vehicle checks
Performing work9 Danger
Never try to perform maintenance
work on high voltage battery
components yourself. You may be
injured and the vehicle may be
damaged. Service and repair of
these high voltage battery
components should only be
performed by a trained service
technician with proper knowledge
and tools. Exposure to high
214Vehicle care3. Release the bonnet support fromits retainer above the radiator
support and place it securely into
the slotted retainer in the bonnet.
Closing
Before closing the bonnet, press the
support into the holder.
Lower the bonnet and let it fall into the latch from a low height (20-25 cm).
Check that the bonnet is engaged.Caution
Do not press the bonnet into the
latch to avoid dents.
Cooling system
The vehicle has three different
cooling systems.
Regularly check the coolant level of
the respective cooling systems and
have the cause of a possible coolant
loss remedied by a workshop.
Caution
Make sure that you never run the
vehicle with insufficient coolant.
A low coolant level can cause
damage to the vehicle.
Heater cooling system
The coolant reservoir is located in the engine compartment.
The coolant provides freeze
protection down to approx. -28 °C.
Caution
Only use approved antifreeze.
If the engine cooling system is cold,
the coolant level should be above the
filling line mark. Top up if the level is
low.
9 Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
To top up use a 1:1 mixture of
approved coolant concentrate mixed
with tap water. Install the cap tightly.
Vehicle care215High voltage battery cooling
system9 Danger
The high voltage battery coolant
may only be serviced by a
qualified technician.
Improper handling could cause serious injuries or death.
The high voltage battery coolantreservoir is located on the front side
of the engine compartment.
Check to see if coolant is visible in the high voltage battery coolant reservoir.
If coolant is visible but the coolant
level is below the cold fill line, there
could be a leak within the cooling
system.
If the coolant level is too low, seek the assistance of a workshop.
Power electronics and charger
modules cooling system9 Danger
The power electronics and
charger modules coolant may only be serviced by a qualified
technician.
Improper handling could cause serious injuries or death.
The power electronics and charger
modules are cooled using the same coolant loop.
The power electronics and charger
modules coolant reservoir is located
on the front side of the engine
compartment.
Check to see if coolant is visible in the
power electronics and charger
modules coolant reservoir. If coolant
is visible but the coolant level is below the cold fill line, there could be a leak
in the cooling system.
If the coolant level is too low, seek the assistance of a workshop.
216Vehicle careWasher fluid
Fill with clean water mixed with a
suitable quantity of approved
windscreen washer fluid which
contains antifreeze.
When adding windscreen washer
fluid to the vehicle, be sure to read the
manufacturer's instructions before
use.
Caution
Only washer fluid with a sufficient
antifreeze concentration provides
protection at low temperatures or
a sudden drop in temperature.
● When using concentrated washer fluid, follow the
manufacturer's instructions for
adding water.
● Do not mix water with ready-to- use washer fluid. Water can
cause the solution to freeze and
damage the washer fluid tank
and other parts of the washer
system.
● Fill the washer fluid tank only three quarters full when it is verycold. This allows for fluid
expansion if freezing occurs,
which could damage the tank if it
is completely full.
● Do not use engine coolant (antifreeze) in the windscreen
washer. It can damage the
windscreen washer system and
paint.
Washer fluid 3 248.
Brakes In the event of minimum thickness ofthe brake lining, a squealing noise
sounds during braking.Continued driving is possible but
have the brake lining replaced as
soon as possible.
Once new brake linings are installed,
do not brake unnecessarily hard for
the first few journeys.
Brake fluid9 Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes,
skin, fabrics and painted surfaces.

After having changed defective fuses,
close the fuse box cover and press
until it engages.
If the fuse box cover is not closed
correctly, malfunctions may occur.
