214Vehicle careCaution
The air suspension system must
be switched off prior to jump
starting.
Air suspension 3 141.
● 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 volts). 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 3 141.
● 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 care215Jump starting procedure
Depending on model, the jump start
terminal may be located at the left-
hand or right-hand side of the engine
compartment.
Lead connection order:
1. Connect the red lead to the positive terminal (1) of the booster
battery.
2. Connect the other end of the red lead to the jump start terminal (2)
of the vehicle with the discharged
vehicle battery.
3. Connect the black lead to the negative terminal (3) of the
booster battery.
4. Connect the other end of the black
lead to a vehicle grounding point
(4), such as the engine block or an
engine mounting bolt. Connect as
far away from the discharged
vehicle battery as possible,
however at least 60 cm.
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 start.
2. After five minutes, start the other engine. Start attempts should be
made for no longer than
15 seconds at an interval of
one minute.
3. Allow both engines to idle for approx. three 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.
