If the journey is continued in less than
2 hours after the ignition is switched
off, the new data is added to the data
already stored in the memory. The
memory will automatically be deleted if

Coolant specifications
The engine cooling system is supplied from
the factory with a specially treated mixture of
water and at least 40 % of the additive G13
(TL-VW 774 J), purple. This mixture gives the
necessary frost protection down to -25°C
(-13°F) and protects the light alloy parts of
the engine cooling system against corrosion.
It also prevents scaling and considerably rai-
ses the boiling point of the coolant. 60

The essentials
Towline anchorages
Att ac
h the b
ar or rope to the towline ancho-
rages.
The towline anchorages are located under
the floor panel in the luggage compartment,
next to the vehicle tools ›››
 page 95.
Screw the towline anchorage into the screw
connection ››› Fig. 77 o ››› Fig. 78 and tighten
it with the wheel brace.
Tow rope or tow bar
The tow bar offers increased safety and a
lower risk of damage.
The tow rope is recommended when there is
no tow bar. It must be elastic so that it does
not damage the vehicle.
Notes for the driver of the towing vehicle
● The tow rope must be taut before you drive
off.
● Rel

ease the clutch very carefully when start-
ing the v
ehicle (manual gearbox), or acceler-
ate gently (automatic gearbox).
Driving style
Towing requires some experience, especially
when using a tow rope. Both drivers should
realise how difficult it is to tow a vehicle. In-
experienced drivers should not attempt to
tow. Do not pull too hard with the towing vehicle
and take c

are to avoid jerking the tow rope.
When towing on an unpaved road, there is al-
ways a risk of overloading and damaging the
anchorage points.
Switch on the ignition so that the turn sig-
nals, windscreen wipers and windscreen
washer can work. Ensure that the steering
wheel is unlocked and moves freely.
Place the gear lever in neutral on vehicles
with a manual gearbox. With an automatic
gearbox, place the lever in N.
To brake, press the brake pedal firmly. The
brake servo does not work when the engine
is switched off.
The power steering only works when the igni-
tion is switched on and the vehicle is moving,
provided that the battery is sufficiently charg-
ed. Otherwise, it will need more force.
Ensure that the tow rope remains taut at all
times.

If the engine will not start, first try starting it

››› page 70. You should only attempt to tow-
start a vehicle if charging the battery does
not work. This is done by leveraging wheel
movement.
