The essentials
Releasing the selector lever
● Using a screwdriver, press and hold the yel-
lo w u
n
locking tab sideways ››› Fig. 55.
● Now press the interlock button on the se-
lector l
ever A and move the selector lever to
po s
ition
N.
● After carrying out the manual release, at-
tach the sel
ector lever boot on the gearbox
console again. If the power supply should ever fail (e.g. dis-
char

ged battery) and the vehicle has to be
pushed or towed, the selector lever must first
be moved to position N, after operating the
manual release mechanism. WARNING
The selector lever may be moved out of posi-
tion P only when the h

andbrake is firmly ap-
plied. If this does not work, secure the vehi-
cle with the brake pedal. On a slope the vehi- cle could otherwise start to move inadver-
tently
af

ter shifting the selector lever out of
position P - accident risk! Air conditioning

The essentials
even in warm climates where anti-freeze pro-
t ection i
s
not required.
If for weather reasons further protection is
necessary, the proportion of additive may be
increased, but only up to 60 %; otherwise an-
tifreeze protection will diminish and this will
worsen cooling.
When the coolant is topped up, use a mixture
of distilled water and at least 40 % of the
G13 or G12 plus-plus (TL-VW 774 G) additive
(both are purple) to obtain an optimum anti-
corrosion protection ››› in Topping up cool-
ant on p ag
e 251

. The mixture of G13 with
G12 plus (TL-VW 774 F), G12 (red) or G11
(green-blue) engine coolants will significant-
ly reduce anti-corrosion protection and
should therefore be avoided ››› in Topping

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 86.
Screw the towline anchorage into the screw
connection ››› Fig. 76 o ››› Fig. 77 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.

››› in General information on page 89
››› page 89 Tow-starting
If the engine will not start, first try starting it
us
in

g the battery of another vehicle
››› page 62. You should only attempt to tow-
start a vehicle if charging the battery does
not work. This is done by leveraging wheel
movement.
When tow-starting a vehicle with a petrol en-
gine, do not tow it more than a short dis-
tance, otherwise unburned fuel can enter the
catalytic converter.
● Engage 2nd or 3rd gear before moving off.
● Press the clutch and hold the pedal down.
● Switch the ignition on.
● Once both vehicles are moving, release the
clut c

h.
● As soon as the engine has started, press
the clutc
h and move the gear lever to neutral.
How to jump start Jump lea
ds The jump lead must have a sufficient wire
c
r
o

ss section.
If the engine fails to start because of a dis-
charged battery, the battery can be connec-
ted to the battery of another vehicle to start
the engine. 62

The essentials
Jump leads must comply with standard DIN
72553 (see c ab
l
e manufacturer's instruc-
tions). The wire cross section must be at least
25 mm 2
for petrol engines and at least
35 mm 2
for diesel engines. Note
● The v ehic

les must not touch each other,
otherwise electricity could flow as soon as
the positive terminals are connected.
● The discharged battery must be properly
connected t
o the on-board network. How to jump start: description

– For vehicles with Start-Stop system: con-
nect one end of
the black jump lead X to a
s uit
ab
le ground terminal, to a solid piece of
metal in the engine block, or to the engine
block itself ››› Fig. 79. 5. Connect the other end of the
black
jump
lead X to a solid metal component bolted
t o the en
gine b
lock or to the engine block
itself of the vehicle with the flat battery.
Do not connect it to a point near the bat-
tery A .
6. Position the leads in such a way that they cannot
c

ome into contact with any moving
parts in the engine compartment.
Starting
7. Start the engine of the vehicle with the boostin
g battery and let it run at idling
speed.
8. Start the engine of the vehicle with the flat batter
y and wait for 2 or 3 minutes until
the engine is running.
Removing the jump leads
9. Before you remove the jump leads, switch off the dipped be
am headlights if they are
switched on.
10.
Turn on the heater blower and heated rear
window in the vehicle with the flat battery.
This helps minimise voltage peaks which
are generated when the leads are discon-
nected.
11.When the engine is running, disconnect the lea
ds in reverse order to the details
given above. » 63

The essentials
Make sure the battery clamps have sufficient
met al-t
o-met
al contact with the battery termi-
nals.
If the engine fails to start after about 10 sec-
onds, switch off the starter and try again after
about 1 minute. WARNING
● Ple a

se note the safety warnings referring to
working in the engine compartment
›››  page 246.
● The battery providing assistance must have
the same v
oltage as the flat battery (12V) and
approximately the same capacity (see imprint
on battery). Failure to comply could result in
an explosion.
● Never use jump leads when one of the bat-
teries
is frozen. Danger of explosion! Even af-
ter the battery has thawed, battery acid could
leak and cause chemical burns. If a battery
freezes, it should be replaced.
● Keep sparks, flames and lighted cigarettes
awa
y from batteries, danger of explosion.
Failure to comply could result in an explo-
sion.
● Observe the instructions provided by the
manufact
urer of the jump leads.
● Do not connect the negative cable from the
other vehic
le directly to the negative terminal
of the flat battery. The gas emitted from the
battery could be ignited by sparks. Danger of
explosion. ●
Do not att ac

h the negative cable from the
other vehicle to parts of the fuel system or to
the brake line.
● The non-insulated parts of the battery
clamp
s must not be allowed to touch. The
jump lead attached to the positive battery
terminal must not touch metal parts of the ve-
hicle, this can cause a short circuit.
● Position the leads in such a way that they
cannot c
ome into contact with any moving
parts in the engine compartment.
● Do not lean on the batteries. This could re-
sult
in chemical burns. Note
The vehicles must not touch each other, oth-
erw i

se electricity could flow as soon as the
positive terminals are connected. Changing the wiper blades
