250Vehicle careJump startingDo not start with quick charger.
A vehicle with a discharged vehicle
battery can be started using jump
leads and the vehicle battery of
another vehicle.9 Warning
Be extremely careful when starting
with jump leads. Any deviation
from the following instructions can
lead to injuries or damage caused
by battery explosion or damage to the electrical systems of both
vehicles.
9 Warning
Avoid contact of the battery with
eyes, skin, fabrics and painted
surfaces. The fluid contains
sulphuric acid which can cause
injuries and damage in the event
of direct contact.
● 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 battery before connecting jump leads.
● Wear eye protection and protective clothing when
handling a 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 16 mm 2
(25 mm 2
for
diesel engines).
● Do not disconnect the discharged
vehicle battery from the vehicle.
● Switch off all unnecessary electrical consumers.
● 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, 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.

252Vehicle careCaution
Deactivate the driver assistance
systems like active emergency
braking 3 188, otherwise the
vehicle may automatically brake during towing.
Switch the selector lever to neutral.
Release the parking brake.
Caution
Never tow a vehicle equipped with All Wheel Drive (AWD) with the
front or rear tyres on the road. If
you tow a vehicle equipped with
AWD while the front or rear tyres
are rolling on the road, the drive
system in the vehicle could be
severely damaged. When towing
vehicles equipped with AWD, all
four tyres must not be in contact
with the road.
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 flange into the
recess and fix cap by pushing.
Towing another vehicle
On the rear bumper, press the cover
plate on its upper left corner to unclip it.
The towing eye is stowed with the
vehicle tools 3 234.
