Trailer towing
Driving with a trailer
General information
Your veh icle is primari ly intended for transport­
ing peop le and luggage. Howeve r, if you dr ive
with a tra iler , follow the techn ica l requirements ,
the operation and driving tips, and the lega l reg ­
ulations.
Dr iving w ith a trailer affects the vehicle 's fuel
consumpt ion, performance and wear. It a lso re­
quires higher concentration from the driver .
A WARNING
Do not transport any people in a trailer due to
the risk of fatal injury .
Technical requirements
Certain requirements must be met when towing
a trailer.
Trailer hitch
Only use a trailer hitch with a removab le ball
h itch mount and ball h itch. The tra ile r hitc h must
be pe rm it t ed for the vehicle, the tra iler and the
permitted tota l weight of the trailer being
pu lled . Above all, it must be secure ly and safe ly
attached to the vehicle trailer.
Never mo unt a t rai ler hitch on the bumper. The
trai ler hitc h must be mounted in a way that does
not impair the function of the bumper. Do not
make any changes to the exhaust system and the
brake system.
Check regu larly if the trai ler hitc h is securely
mounted . A lways follow the instructions given by
the trai ler hitch manufacturer .
Trailer brakes
If t he tra ile r has its own bra ke system, then fol­
low the manufacturer specifica tions. Howeve r,
the brake system on the trai ler must never be
connected to the vehicle brake system.
92
Engine cooling system
D riving w ith a tra ile r means a higher load on t he
engine and the cooling sys tem. The coo ling sys­
tem must be designed for additiona l load and
contain enoug h coo lant ~@ .
A WARNING -
- Never mount a "weight -distributing" or
"load-balancing" trailer coupler as the trail­
er hitch. The ve hicle was not des igned for
these types of tra iler h itches. The tra iler
h itch can malfunction and t he tra ile r can
b reak off from the vehicle.
- If t he tra ile r i s equ ipped w ith elect ronic
brakes, these brakes can not be activated by
a facto ry-installed control system, whi ch in­
creases the r isk of an accide nt.
- To red uce the r is k of injury, always remove
the ball hitch mount if no tra ile r is mo unt ­
ed.
@ Note
L onge r incl ines cannot be dr iven without a
su itab le cooli ng system, especially if the out­
s ide temperatu res a re high. ot herwise, this
i nc reases the risk of eng ine da mage.
Operating instructions
Several things must be noted when towing a
trailer.
Towing capacity
The permitted towing capacity must not be ex ­
ceeded under any circumstances~
page 376.
You can dr ive up larger inclines if you are not us­
i ng the maximum towing capacity.
The towing capacities given only apply to e leva ­
tions up to 3,200 ft (1,000 m) above sea level. As
the e levation increases, the engine power de­
creases due to the decreasing air pressures. T his
reduces the hill climb ing ability and towing ca­
pac ity . For every additional 3,200
ft (1,000 m),
t h e maximum permitted tow ing weight must be
r educed by app roximately 10% . T he pe rm itted
tow ing weight is t he comb ined we igh t of the
( loaded) vehicle and the (loaded) trailer .

Cl a:, ...... N

::r ' Tongue weight
The maximum permitt ed tongue weight of the
trailer drawbar on the trailer hitch ball head may
not be exceeded .
If the tongue we ight is too low, this affects the
trailer's handling . For driv in g safety, we recom­
mend to always utilize the maximum permitted
tongue weight, but not exceed it. You can reach
it, for example , by distributing the cargo in the
trailer correctly.
You can determine the tongue weight, for exam­
ple, with a bathroom scale or a public weigh sta ­
tion .
The permitted tongue weight of your veh icle can
be found in the vehicle documentation or in
¢page 376.
Load distribution
Poor cargo load and distribution can negatively
i mpact ve hicle handl ing.
- Store objects preferably in the vehicle luggage
compartment . The vehicle shou ld always carry
the heaviest possible load and the trailer
shou ld have the lightest possible load.
- Distribute the load in the tra iler so that the
heavy objects are as close to the axle as possi­
ble.
- Secure objects from slid ing out of p lace.
- Utilize the maximum permitted tongue weight
if possible .
Tires
Set the tire pressure on your vehicle for a "full
load"; see the t ire pressure sticker¢
page 340.
If necessary, also adjust the tire pressure on the
trailer according to the manufacturer's recom­
mendation .
The tire pressure must be increased an addi tional
3 PS I (0 .2 bar) for towing loads over 6,600 lbs
(3,000 kg) .
W inter tires shou ld be mounted on the vehicle
and on the trailer during winter temperatures .
Trailer towing
Outside mirrors
If you cannot see the traffic behind the trailer
with the standard exterior mirrors, then you
must attach additional exterior mirrors. Adjust
them so you have a sufficient visibility behind
you.
Exterior lighting
Follow the legal regu lations rega rding the light ­
ing equipment on your trailer. Contact an author­
ized Audi dea ler or authorized Audi Service Facili­
ty for more information.
Before starting to drive , check all lighting eq uip­
ment on the hitched trailer.
T he headl ight range cont rol adj usts automat ica l­
ly to the light range of the headlights .
Safety chains
Make sure the safety chains are correctly applied
when pulling a trailer . The cha ins should hang
enough so that the trailer can drive around
curves . Howeve r, they must not touch the
ground.
Air suspension
Applies to: vehicles with air suspension
The air suspens ion must be at the standard vehi ­
cle he ight before you set the tongue weight on
the tra iler and hitch the trailer¢@ ,
¢page 130,
Raising/lowering the vehicle.
For vehicles with a factory-installed trailer hitch,
the a ir suspension trailer mode w ill automatically
switch on if you connect the trailer cable to the
socket.
For vehicles with a retrofitted trailer hitch, you
must sw itch on the a ir suspension trailer mode
manua lly . Select in the Infotainment system:
IMENU I button> Vehicle > left control button>
Vehicle settings > Air suspension: trailer. Switch
it off again after towing a trailer.
You can also sw itch off trailer mode manually
wh ile dr iving, for example, whe n using a bicycle
rack system. ..,.
93

Trail er to wing
If you have to drive th rough diffic ult road condi­
tions, you can raise the vehicle again after hitch ­
ing the trai ler or after adjust ing the tongue
weight .
{QJ Note
Applies to: vehicles with air suspension
-Changes in temperature or load can affect
the he ight of the vehicle.
- Set the a ir suspension to the standard vehi­
cle heig ht, otherwise the applicab le tongue
weig ht no longer applies to your vehicle .
(D Tips
-Use chocks when parking on incl ines if the
trailer is loaded.
- We recommend also having the vehicle in­ spected between the inspection intervals if
you are towing a trai ler frequently.
- Avo id driving wit h a trailer du ring the vehi­
cle break-i n period .
Driving with a trailer
Driving with a trailer requires extra caution.
Speed
Adhere to the legal speed l imi ts. Follow t he lega l
regulations specif ic to the country.
As the speed inc reases, the d riving stability of
the t railer dec reases . The refore you sho uld not
exceed t he max imum legal speed limit when
there are unfavorable road, weather and/or wind
conditions. This especially applies when driving
downhill.
You must a lways reduce yo ur speed as soon as
you not ice even the s lightest swinging motion of
the trailer . Never try to "straighten out" the trail ­
er by accelerating.
The weig ht dis trib ution is very poo r if t he ve hicle
is empty and the trailer is loaded. However if you
must drive under these circumstances, t hen drive
especia lly slowly.
94
Brak es
Brake in a time ly manner. Downs hift be fo re dr iv ­
i ng down hill so that the engine can assist with
braking ~&, .
When using a t railer w it h over run bra kes, fi rst
brake ge ntly t hen q uickl y. This red uces the r isk o f
jerking while braking if the trailer wheels lock up .
Engine coolant temperatur e
Pay attention specifically to the coolant tempera­
ture display when there a re high outs ide temper­
at ures , and whe n driving on long i nclines
~ page 11. Shift to a highe r gear in a t imely man­
ner .
A WARNING
Constant braking causes the b rakes to over­
h eat and substantially reduces bra king per ­
formance, increases b raking distance o r caus­
es complete failure of the brake system.
-

Ass is tanc e system s
the cruise control from braking. This is be ­
cause pressing the accelerator pedal over­
rides the cruise contro l system .
- If a brake system ma lfunction such as over­
heating occurs when the cruise control sys­
tem is sw itched on, the braking function in
the system may be switched off . The rest of
the cruise control system functions remain act ive as long as
the @;\l)~ij (USA models) /
Bl (Canada models) indicato r light is on.
@ Note
Before driving downhill a long distance on a
steep hill, decrease you r speed and select a
lower gear. This makes use of the eng ine
brak ing effect and re lieves the bra kes.
(D Tips
The b rake l ights turn on w hen the brakes a re
app lied automat ically .
Changing the speed
Applies to: vehicles with cruise control system
.,. To inc rease/decrease the speed in 1 mph (1

-
- Read the wa rnin gs on ¢.&. in General infor­
mation on page 103 and on¢
& in De­
scription on page 97.
- Pay attent ion to traffic and the a rea around
your veh icle when pred ictive cont rol is
sw itched on. The driver is always responsi­
ble for assessing the traffic situation.
- There is an increase in the risk of an acci­
dent, because the system does not consider
"right of way" rules and also does not re ­
spond to traffic lights .
- The system only cons iders t raff ic signs that
g ive a speed lim it .
- The permitted speed can be exceeded if the
adaptation to a speed lim it is incorrect . The
d river is responsible for adher ing to the pe r­
mitte d speed .
- The s peed at w hich a curve is dr iven th rough
does not necessarily match your own driving
s tyle. Brake the vehicle yo urself whe n need­

0) Tips
- If a speed lim it is detected, the stored
speed is also adjusted in the speedometer LE D line when the ada ptive cru ise control is
n ot a ctive .
- The adaptat ion by the system depends on
t he driving mode se t in dr ive se lec t*.
- Switching off predict ive con trol, fo r exam­
ple whe n driving in low t raff ic zones, does
101

Ass is tanc e system s
not cause the adaptive cruise control to
switc h off .
- After switching on t he ignit ion, the system
initially adj usts to a speed of 80 mph
(130 km/h) when driving onto highways
without a speed limit. Then the system ad­
justs to the last speed stored by the driver.
- There is no adaptation to speed limits when

Applies to: vehicles with Audi adaptive cruise control
Fig. 94 Detect ion ra nge
The adaptive cru ise cont rol system is a comb ina­
t ion of speed and dis tance regu lation .
It assists
t h e d river by bo th regu lating the speed and
maintain ing a d istance to the vehicle driv ing
ahead, within the limits of the system.
If the sys­
tem detects a vehicle d riving ahead, the adaptive
cruise contro l can brake and accelerate your vehi ­
cle. T his makes driving more comfortable both
o n long stretches of highway and in stop -and-go
traffic.
What can adapti ve cruise control do?
The adaptive cru ise control system uses video, ra­
dar, ultrasound and navigation data . Vehicles
driv ing ahead can be recognized up to 650 ft
(200 m) away .
Pred ictive functions offer the driver additional
comfort and contr ibute to the reduct ion in fuel
