13 Earth for pin 9 Power socket for trailer
The vehicle is fitted with a 13-pol
e po
wer
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

Type of petrol  Valid for: vehicles with petrol engines
The correct grade of petr ol is list

ed inside the
fuel tank flap.
The vehicle is equipped with a catalytic con-
verter and must only be run on unleaded
petrol. The petrol must comply with the
standard EN 228 and be sulphur-free. Fuels
with a 10% ethanol ratio can be refuelled
(E10) 1)
. The types of petrol are differentiated
by using the octane numbers (RON) or via
the anti-knock index (AKI).
Super unleaded petrol 95 octane petrol or
normal 91 octane petrol at least
We recommend refuelling with super 95 oc-
tane petrol (91 AKI). If not available, normal 91
octane petrol (87 AKI) (with a slight power
loss) may be used.
Super unleaded petrol, 95 octanes at
least
You should use super 95 octane petrol (91
AKI) at least. 3 If super is not available, if necessary, use nor
-
mal 91 oct ane petrol (87 AKI). In this case only
use moder at

e engine speeds and a light
throttle. Refuel with super as soon as possi-
ble.
Unleaded super plus 98 octane petrol or
super 95 octane petrol at least
We recommend refuelling with super plus 98
octane petrol (93 AKI). If not available: super
95 octane petrol (91 AKI) (with a slight power
loss).
If super is not available, if necessary, use nor-
mal 91 octane petrol (87 AKI). In this case only
use moderate engine speeds and a light
throttle. Refuel with super as soon as possi-
ble. CAUTION

the marking “Petrol/ethanol”.
Vehicles with Totalflex engine can run with
unleaded petrol (95 octane / 91 AKI) accord-
ing to ANP No. 57 and with fuels with any high
percentage of ethanol. The vehicle is refuel-
led in the same way as petrol refuelling.

Note
The layout of parts may vary depending on
the engine. Engine oil
General notes The engine comes with a special, multi-grade
oil that can be used all year round.
Because the use of high-quality oil is essen-
tial for the corr
ect oper
ation of the engine
and its long useful life, when topping up or
changing oil, use only those oils that comply
with VW standards.
We recommend that the oil change be done
by a technical service or specialised work-
shop.
If the engine oil level is too low
You can get information about the correct en-
gine oil for your vehicle at your workshop.
If the recommended engine oil is not availa-
ble, in the event of an emergency you can
change the oil once with a maximum of 0.5 L
of the next oil until the next oil change:
Petrol engines: standard VW 504 00,

Warning lamp 
It lights up
Alternator fault. The control lamp lights up when the ignition is
switched on. It should go out when the engine
has st art
ed running.
If the control lamp  lights up while driving, the alternator is no longer charging the bat-
tery. You should immediately drive to the
nearest specialised workshop.
You should avoid using electrical equipment
that is not absolutely necessary because this
will drain the battery.
Checking the battery electrolyte
level The electrolyte level should be checked reg-
ul
arly in high-mil

tries and in ol

der batteries.
