Vehicle care219Caution
The air suspension system must
be switched off prior to jump
starting.
Air suspension 3 144.
● 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.
● Switch off all unnecessary electrical consumers.
● Switch off the air suspension system 3 144.
● 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.

Vehicle care221Towing
Towing the vehicle The towing eye and wheel wrench are stowed with the vehicle tools 3 204.
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.
Caution
Do not tow the vehicle from the
rear. The front towing eye must
only be used for towing and not
recovering a vehicle.
Switch on ignition to permit operation
of brake lights, horn and windscreen
wipers, and move the steering wheel
slightly to release the steering wheel
lock.
Switch off the air suspension system 3 144.
Caution
Deactivate the driver assistance
systems like active emergency
braking 3 167, otherwise the
vehicle may automatically brake during towing.
Move the selector lever to neutral.
Release the parking brake.
Caution
Vehicles with manual
transmission automated: If neutral cannot be selected, the vehiclemust only be towed with the drive
wheels raised off the ground.
The vehicle should always be
towed with the ignition switched
off.
Manual transmission automated
3 154.
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 fumes
from the towing vehicle, switch on the air recirculation system 3 121 and
close the windows.
Seek the assistance of a workshop.

222Vehicle careAfter towing, unscrew the towing eyeand refit the cover.
Towing another vehicle
Attach a tow rope – or better still a tow
rod – to the rear towing eye, never to
the rear axle and suspension units.
Caution
The rear towing eye must only be
used for towing and not recovering a vehicle.
Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
Appearance care
Exterior care Locks
The locks are lubricated at the factory using a high quality lock cylinder
grease. Use de-icing agent only when absolutely necessary, as this has a
degreasing effect and impairs lock function. After using a de-icing agent,
have the locks regreased by a
workshop.
WashingThe paintwork of your vehicle is
exposed to environmental influences.
Wash and wax your vehicle regularly.
When using automatic vehicle
washes, select a programme that
includes waxing. Restrictions for
filmed or matt painted body parts or
decor tapes, see "Polishing and
waxing".
Bird droppings, dead insects, resin,
pollen and the like should be cleaned
off immediately, as they contain
aggressive constituents which can
cause paint damage.
