Intr oduction Take into account country-specific regula-
tions about driving with a trailer and the use
of a to wing br
acket.
The vehicle has been developed primarily for
carrying people, although it can also be used
to tow a trailer if fitted with the corresponding
technical equipment. This additional load has
an effect on the useful life, fuel consumption
and vehicle performance and in some cases
can reduce the service intervals.
Driving with a trailer requires more force from
the vehicle, and thus more concentration
from the driver.
In winter, winter tyres should be fitted on both
the vehicle and the trailer.

socket for the connection between the trailer
and the vehicle. With the engine running,
electrical devices on the trailer receive power
from the electrical connection (pin 9 and pin
10 of the trailer power socket).
If the system detects that a trailer has been
connected, the consumers on the trailer will
receive electricity through this connection
(pins 9 and 10). Pin 9 has a permanent live.
This powers, for example, the trailer
