Driving the vehicle with a
trailer or caravan
Technical requirements

The
towing bracket must comply with certain
technical requirements.
Your car is intended mainly for transporting pas­
sengers and luggage. However, if suitably equip­

ped,
it can also be used to tow a trailer or cara­

van.

If the car is supplied with a factory-fitted towing
bracket it will already have the necessary techni­
cal modifications and meet the statutory require­
ments.
A 13-pin socket is provided to make the electrical
connection between the car and the trailer. If the
trailer you wish to tow has a 7-pin plug, the nec­
essary adapter cable can be obtained from a spe­
cialist retailer.
If
a
towing bracket is to be fitted after the car is

purchased,
this must be done according to the in­
structions of the towing bracket manufacturer

^page
102.
A WARNING
If
a
towing bracket is retrofitted, the installa­
tion should be carried out by
a
qualified work­

shop.

- In particular in high outside temperatures it
is not possible to drive up long steep gradi­
ents without
a
suitable cooling system. The
engine would then overheat.
- Incorrect installation can result in a safety
risk.
Points to check before towing
There are a number of points which need to be
checked before towing a trailer or caravan.

*•
Observe the maximum permitted trailer
weights
^>page
342.
Trailer weights
Never exceed the maximum permitted trailer
weights.
If
you
do not load the trailer up to the maximum
permitted trailer weight, you can then climb cor­
respondingly steeper gradients.
The maximum trailer weights listed are only ap­
plicable for altitudes up to 1000 m above sea

level.
With increasing altitude the engine power
and therefore the car's climbing ability are im­
paired because of the reduced air density, so the
maximum trailer weight has to be reduced ac­
cordingly. The weight of the car and trailer must
be reduced by about 10% for every further
1000 m (or part thereof). This figure refers to
the combined weight of the (loaded) vehicle and
(Loaded) trailer.
The figures for the draw bar weight that appear
on the identification plate of the towing bracket
are for certification purposes only. The correct
figures for your specific model, which may be
lower than these figures for the towing bracket,
are given in the registration documents and in

•=>
page 343.
Drive select*
Please note that the
efficiency*
mode is not
available in towing mode.
Exterior lights
Before starting
a
journey, make sure that all the
lights for the trailer are working properly.
Distributing the load
Distribute loads in the trailer so that heavy ob­
jects are as near to the axle as possible. Loads
carried in the trailer must be secured to prevent
them slipping. A badly distributed load can also
affect handling. This can activate the trailer sta­
bilisation feature and cause the vehicle to reduce

speed.

Where possible, operate the trailer with the max­
imum permitted draw bar weight on the ball
joint of the towing bracket, but do not exceed the
specified limit. •

Towing a trailer
Tyre pressure
Check the tyre pressures on your car, and adjust
for "full
load"
conditions (refer to the sticker list­
ing the tyre pressures)
^>page
307. It may also
be necessary to adjust the tyre pressures on the
trailer according to the recommendations of the
trailer manufacturer.
Exterior mirrors
Check whether you can see enough of the road
behind the trailer with the standard mirrors. If
this is not the case you should have additional
mirrors fitted. Both exterior mirrors should be
mounted on hinged extension brackets. Adjust
the mirrors to give sufficient vision to the rear.
Headlights
Before starting
a
journey, check the headlight
beam settings with the trailer hitched up. Adjust
the headlight settings if necessary.
On vehicles with halogen headlights, the
head­

light range control must be adjusted, see

tapage
49.
The headlight range control will be adjusted au­
tomatically if your vehicle is equipped with LED
headlights*.
Power supply
To ensure that the engine can be started again
after the ignition is switched off, the power
man­

agement system
^>page
149 controls the distri­
bution of electrical power and gradually switches
off unnecessary electrical equipment. The trailer
is supplied with power during this period. The
power supply to the trailer is interrupted while
the engine is being started.
Removable ball joint coupling
Vehicles with a factory-fitted towing bracket are
equipped with a removable
ball
joint coupling.
This is stored in the spare wheel well or in a sepa­
rate bag on the floor of the luggage compart­
ment, together with the necessary fitting instruc­

tions.

We recommend having the car serviced be­
tween the normal inspection intervals if it
used frequently for towing a trailer.
Trailer stabilisation system
Applies to: vehicles with towing bracket
Trailer stabilisation helps to reduce the risk of
the vehicle skidding when towing a
trailer.

When is the trailer stabilisation
system1'

activated?
Trailer stabilisation is active when the following
requirements are met:
- The ESC must be switched on
^>page
146 and
fully functional (no ESC malfunction).
- The trailer connector must be properly secured
in the vehicle socket.
- The vehicle speed must be higher than approx.
60 km/h.
How trailer stabilisation works
In many cases, the driver can stabilise a swaying
trailer by manually braking the vehicle.
However, if the ESC detects that the trailer is
swaying and this is affecting the towing vehicle,
it will automatically brake the vehicle in order to
stabilise the trailer. The indicator
Lamp Hi
will
flash in the instrument cluster. If possible, do
not turn the steering wheel at this stage.
In order to warn traffic behind you, the brake
lights will come on during this automatic braking

operation.

A trailer may sway quite considerably without the
trailer stabilisation system intervening.
If the system for activating the trailer brake
lights is defective, this will be indicated in the in­
strument cluster display

Electronic stabilisation control
The
ESC
-
in particular in conjunction with the
trailer stabilisation system
o^page

it

easier to stabilise a trailer
if it
starts to skid
or

sway. You should therefore keep the
ESC
switch­
ed on
at
all times.
Overheating
In hot weather, keep an eye on the coolant
tem­

perature gauge
^page
13. When climbing long
hills with the engine running fast in low gear, the
coolant temperature can increase. Reduce speed
immediately
if
the needle moves to the right end
of the scale. For information on the warning
lamp

Rear carrier systems
When using rear carrier systems (e.g. bicycle
racks) on the towing bracket,
it
is important not
to exceed the maximum load.
The total weight
of
the rear carrier system and
its

load must not exceed
75
kg for this vehicle. How­
ever,
it
is also important to observe the maxi­
mum permissible load for the rear carrier sys­

tem.

The greater the distance from the towing brack­
et, the smaller the maximum permissible Load
on

the rear carrier system. For this reason, you
should secure heavy objects as near as possible
to the towing bracket.
Note the instructions provided by the manufac­
turer of the rear carrier system.
Please make sure that the rear carrier system
is

approved for use on your vehicle.

l
Note
A WARNING
The use of an unsuitable rear carrier system
could cause severe damage
to
the towing
bracket. The towing bracket could then break
and cause an accident.
Degrease and clean the ball joint before using
a rear carrier system.

Fuel
Petrol grade
Applies to: vehicles with petrol engine

The
correct grade of petrol is listed inside the
fuel tank flap.
The vehicle is equipped with a catalytic converter
and must only be run on unleaded petrol. Petrol
must be sulphur-free and must comply with the
EN 228 standard. You can fuel your vehicle with
fuels containing a maximum of 10%
ethanol

(E10). The petrol grades have different octane
ratings (RON).
The following headings relate to the sticker on
the inside of your vehicle's tank flap:
Unleaded fuel only RON/ROZ
95
Super,
Premium or
min.
RON/ROZ 91 Normal
The use of premium petrol (95 RON) is recom­

mended.
If
that
type of fuel is not available,
reg­

ular petrol (RON 91) can be used with a slight
loss of power.
Unleaded fuel only, min. RON/ROZ
95

Super, Premium
Premium petrol (at least 95 RON) must be used.
If premium petrol is not available, the engine can
be run on regular petrol with 91 RON as an
emer­

gency measure. In this case only use moderate
engine speeds and a light throttle. Fill up with
premium or Super Plus petrol as soon as possi­

ble.

Unleaded fuel only RON/ROZ 98 Super Plus
or min. RON/ROZ 95 Super, Premium
The use of Super Plus petrol (98 RON) is recom­

mended.
If
that
type of fuel is not available, pre­
mium petrol (RON 95) can be used with a slight
loss of power.
If premium petrol is not available, the engine can
be run on regular petrol with 91 RON as an
emer­

gency measure. In this case only use moderate
engine speeds and a light throttle. Fill up with
premium or Super Plus petrol as soon as possi­

ble.

© CAUTION
- Do
NOT fuel
your vehicle with
high-ethanol

fuel blends (e.g. E50 or E85). This will dam­
age the fuel system.
- just one tank of leaded fuel or fuel with
metallic additives will permanently impair
the efficiency of the catalytic converter.
- You should use only petrol additives which
have been approved by Audi. Additives with
so-called octane boosters or antiknock
addi­

tives can contain metallic additives that
cause significant damage to the engine and
the catalytic converter. Do not use such ad­
ditives.
- Metal-based fuels, which can be identified
from the marking on the fuel dispenser,
must not be used. LRP fuel (lead replace­
ment petrol) also contains high concentra­
tions of metallic additive. Risk of engine
damage!
- High engine speed and full throttle can
damage the engine when using petrol with
an octane rating lower than the correct
grade for the engine.
- You can use higher octane fuel than your en­
gine requires.
- In countries where sulphur-free fuel is not
available, you may use low-sulphur fuel in­

stead.

Diesel fuel
Applies to: vehicles with diesel engine
Please note the information on the inside of the
fuel tank flap.
The use of sulphur-free diesel complying with
the EN 590 standard is recommended.
Diesel can thicken at very low temperatures,
which can result in problems starting the engine
or prevent the engine from running smoothly.
For this reason, filling stations in some countries
offer winter-grade diesel fuel during the cold
289

Checking and topping up fluids
months so that you can continue to operate your
vehicle reliably. Ask at your filling station wheth­
er the diesel fuel available there is suitable for
the current conditions and for the temperatures
which could potentially occur.
© CAUTION
- Never use FAME fuels (biodiesel), petrol,
heating oil, thinners or any other fuels or
additives, as these could cause serious dam­
age to the fuel system and the engine.
- Never start the engine if
you
fill up with the
wrong type of
fuel,
as this could damage
the fuel system and the engine. Obtain pro­
fessional assistance.

A WARNING
Fuel is highly inflammable and can cause
seri­

ous burns and other injuries.
- For safety reasons we do not recommend
carrying a spare fuel canister in the vehicle.
The canister could become damaged in an
accident and Leak.
- Observe all relevant statutory regulations
on using, storing and transporting spare
fuel canisters.
- When filling your tank or
a
spare fuel canis­
ter with
fuel,
do not smoke and keep away
from naked flames
-
risk of explosion!
- If, in exceptional circumstances, you have
to

carry
a
spare fuel canister, please observe
the following warnings:
- Never
filL
fuel into the spare fuel canister
with the canister placed in or on top of the
vehicLe. An electrostatic charge could
build up during filling, causing the fuel va­
pour to ignite
-
risk of explosion! Always
place the canister on the ground to fill
it.

- Insert the filler nozzle as far as possibLe
into the spare fuel canister.
-
If
the spare fuel canister is made of metal,
the filler nozzle must be in contact with
the canister during filling. This helps pre­
vent an electrostatic charge building up.

cle or in the luggage compartment. Fuel
vapour is explosive - danger to life!
© Note
(7) CAUTION
- If any fuel is spilt onto the vehicle, it should
be removed immediately as it could other­
wise damage the paintwork.
- Never run the tank completely dry. If there
is an irregular fuel supply, misfiring can oc­
cur. As a result unburnt fuel can enter the
exhaust system and cause damage to the
catalytic converter(s).
- Applies to vehicles with diesel engine: When
filling the fuel tank after having run it com­
pletely dry, the ignition must be switched
on for at least 30 seconds before the engine
is started. When you then start the engine it
may take longer than normal (up to one mi­
nute) for the engine to start firing. This is
because air needs to be bled from the fuel
system while starting.
® For the sake of the envir
Do not try to put in more fuel after the auto­
matic filler nozzle has switched off; this may
cause the fuel to overflow if it becomes warm.

(T)
Note
Applies to: vehicles with diesel engine
Diesel vehicles are equipped with an incorrect
fuelling protection
system1).
This system en­
sures that the tank can only be fuelled from a
diesel filler nozzle.
- If the filler nozzle is old, damaged or too

small,
it may not be able to open the pro­
tection mechanism on the fuel tank. In this

case,
try turning the filler nozzle before in­
serting it in the fuel filler neck, use a differ­
ent filling pump or seek professional assis­

tance.

- The protection mechanism will not open if
you try to add fuel from a spare fuel canis­
ter. You can get round this simply by adding
the diesel fuel slowly.

Selective catalytic
reduction (AdBLue/DEF)
General notes
Applies to: vehicles with selective catalytic reduction
On vehicles with selective catalytic reduction, a
urea solution (AdBLue/DEF) is injected into the
exhaust system upstream of
a
NOx catalytic
con­

verter in order to reduce nitrogen oxide emis­

sions.
The urea solution is known under the name
of AdBlue or DEF (Diesel Exhaust Fluid). The term
AdBlue is used below.
The AdBlue is held in a separate tank on the
vehi­

cle.
AdBlue consumption is approximately 1.0 -
2.5% of diesel fuel consumption.
As soon as a message appears in the instrument
cluster display reminding you to refill AdBlue,
you must refill the AdBlue tank or have this done
