Specifications
Batteries
The car is equipped with two 12 V batteries –
one extra powerful battery for starting and
one standby battery that helps during the
Start/Stop function’s starting sequence.
Temporarily disengaged Start/Stop function
due high power take-off means:
• The engine does not auto-stop.
• The engine starts automatically
1
without
the driver depressing the clutch.
Battery locations
1. Battery 2. Support battery.
The battery used for starting is described in
detail in the normal owner’s manual.
The standby battery is located under the left-
hand headlamp and does not normally
require service.

NOTE
The higher the power take-off in the car
(extra cooling/heating, etc.) the more the
batteries must be recharged = Increased
fuel consumption.
• When the battery needs charging the
Start/Stop function is temporarily disen-
gaged.
1
Auto-start can only take place if the gear lever
is in neutral position.
IMPORTANT
In the event of the temporary connection of
an external battery for starting or a battery
charger, the car’s negative battery terminals
must
never
be used for connection – only
the chassis may be used as a grounding
point.
• See the owner’s manual – this describes
where and how the cable clamps should
be fitted.
NOTE
If the battery for starting the car has been so
discharged that everything is "black" and
the car, in principle, lacks all the normal
electrical functions, and the engine is then
started using an external battery or battery
charger, then the Start/Stop function will be
activated. It will then be possible to stop the
engine automatically, but the Start/Stop
function may fail to start the engine auto-
matically in the event of a stop.
To ensure successful automatic starting
after a stop, the battery must first be
charged. At an outside temperature of +15
°
C the battery needs to be charged for at
least 1 hour. At a lower outside tempera-
ture, a charging time of 3–4 hours is recom-
mended. The recommendation is to charge
the battery with an external battery charger.
For more information on the charging the
battery, see the owner’s manual.
