Trailer towing
Driving with a trailer
General information
Your vehicle is primarily intended for transport-
ing people and luggage. However, if you drive
with a trailer, follow the technical requirements,
the operation and driving tips, and the legal reg-
ulations.
Driving with a trailer affects the vehicle's energy
usage, performance, and wear. It also requires
higher concentration from the driver.

Z\ WARNING
Do not transport any people in a trailer due to
the risk of fatal injury.
Technical requirements
Trailer hitch

Only use a trailer hitch with a removable ball
hitch mount and ball hitch. The trailer hitch must
be permitted for the vehicle, the trailer and the
permitted total weight of the trailer being
pulled. Above all, it must be securely and safely
attached to the vehicle trailer.
Never mount a trailer hitch on the bumper. The
trailer hitch 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 regularly if the trailer hitch is securely
mounted. Always follow the instructions given by
the trailer hitch manufacturer.
Trailer brakes
If the trailer has its own brake system, then fol-
low the manufacturer specifications. However,
the brake system on the trailer must never be
connected to the vehicle brake system.
Engine cooling system
Driving with a trailer means a higher load on the
engine and the cooling system. The cooling sys-
tem must be designed for additional load and
contain enough coolant > @.
CG) Note
Longer inclines cannot be driven without a
suitable cooling system, especially if the out-
side temperatures are high. Otherwise, this
increases the risk of engine damage.
Operating instructions
Towing capacity
Your vehicle can only be operated with class 1 or
class 2 trailers.
Load distribution
Poor cargo load and distribution can negatively
impact vehicle handling. To have the lowest im-
pact as possible, load the trailer according to
these criteria:
— Store objects in the vehicle luggage compart-
ment, if possible. The vehicle should always
carry the heaviest possible load and the trailer
should have the lightest possible load.
— Distribute the load in the trailer so that the
heavy objects are as close to the axle as possi-
ble.
— Secure objects so that they do not slide.
— Utilize the maximum permitted tongue weight
if possible.
Tires
Set the tire pressure on your vehicle for a “full
load”; see the tire pressure sticker > page 330. If
necessary, also adjust the tire pressure on the
trailer according to the manufacturer's specifica-
tions.
The trailer and the vehicle should be equipped
with winter tires when driving in winter tempera-
tures.
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.

Trailer towing

Exterior lighting
Follow the legal regulations regarding the light-
ing equipment on your trailer. Contact an author-
ized Audi dealer or authorized Audi Service Facili-
ty for more information.
Before you start driving, check all lighting equip-
ment on the trailer while it is hitched to the vehi-
cle.
The headlight range control automatically ad-
justs the light range of the headlights.
Safety chains
Make sure the safety chains are correctly applied
when pulling a trailer. The chains should hang
enough so that the trailer can drive around
curves. However, they must not touch the
ground.
G) Tips
— Block the wheels with chocks when parking
on inclines if the trailer is loaded.
— Having the vehicle inspected between the
inspection intervals is recommended if you
tow a trailer frequently.
— Avoid driving with a trailer during the vehi-
cle break-in period.
Driving with a trailer
Driving with a trailer requires extra caution.
Speed
Adhere to the legal speed limits. Follow the legal
regulations specific to the country.
As the speed increases, the driving stability of
the trailer decreases. Therefore you should not
exceed the maximum legal speed limit when
there are unfavorable road, weather, and/or wind
conditions. This especially applies when driving
downhill.
Hill
When you start driving uphill or downhill, trailers
may tilt or sway sooner than when driving ona
level surface. If small swaying movements have
already occurred, you can stabilize the trailer by
114
firmly braking immediately. Never attempt to
“straighten out” the trailer by accelerating.
Downshift before driving on hills to utilize the en-
gine braking effect > A\.
Brakes
When using a trailer with overrun brakes, first
brake gently then quickly. This reduces the risk of
jerking while braking if the trailer wheels lock up.
Engine coolant temperature
Pay attention specifically to the coolant tempera-
ture display when there are high outside temper-
atures, and when driving on long inclines
=> page 15. Shift to a higher gear in a timely man-
ner.

Z\ WARNING
Constant braking causes the brakes to over-
heat and can substantially reduce braking per-
formance, increase braking distance, or cause
complete failure of the brake system.

Speed warning system
Applies to: vehicles with speed warning system
The speed warning system helps you to stay be-
low a specified maximum speed that can be set,
changed or deleted in the Infotainment system.
The speed warning system warns you if you are
exceeding the maximum speed that you have set.
A warning tone will sound as soon as your speed
exceeds the stored value slightly. The ow in-
dicator light will appear at the same time in the
instrument cluster display along with a message.
The fe) indicator light and the message turn
off if the speed falls back below the stored maxi-
mum speed.
Setting a threshold is recommended if you would
like to be reminded when you reach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a gener-
al speed limit or if there is a specified maximum
speed for winter tires.
Setting the warning threshold

> Select in the Infotainment system: [MENU] but-
ton > Vehicle > left control button > Driver as-
sistance > Speed warning > Manual.
G) Tips
Regardless of the speed warning system, you
should always monitor your speed using the
speedometer and make sure you are following
the legal speed limit.
Messages
Applies to: vehicles with speed warning system
Manually set speed limit XX mph
(km/h) exceeded

The stored speed was exceeded.
Cruise control system
Applies to: vehicles with cruise control system
The cruise control system assists the driver in
maintaining a constant speed above approxi-
mately 15 mph (20 km/h). The system maintains
the desired speed by braking and accelerating.

ZA WARNING
— Always pay attention to the traffic around
your vehicle when the cruise control system
is in operation. As the driver, you are always
responsible for controlling your vehicle
speed and the distance between your vehicle
and
other vehicles.
— For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads, and when road conditions are
poor (such as ice, fog, gravel, heavy rain,
and conditions that could lead to hydroplan-
ing), because this increases the risk of an ac-
cident.
— Switch the cruise control off temporarily
when driving in turning lanes, highway exits,
or in construction zones.
—To reduce the risk of an accident, you should
only resume the stored speed if it is suitable
for the current traffic conditions.
@) Note
— Conventional drive system: before driving
downhill a long distance on a steep hill, de-
crease your speed and select a lower gear.
This makes use of the engine braking effect
and reduces the load placed on the brakes.
— Plug-in hybrid drive: before driving downhill
a long distance on a steep hill, decrease
your speed and use the recuperation braking
effect > page 78. This reduces the load on
the brakes.
(i) Tips
The brake lights turn on when the brakes are
applied automatically.

sense front



Fig. 109 Front of vehicle: sensor
The radar sensor area > fig. 109 must not be cov-
ered with stickers, deposits or any other obstruc-
tions as it may impair the function of the adap-
tive cruise control or the pre sense front. For in-
formation on cleaning, see > page 342. The
same applies for any modifications made in the
front area.
The function of the adaptive cruise control sys-
tem or pre sense front is limited in some condi-
tions:
— Vehicles can only be detected when they are
within the sensor range > page 118, fig. 108.
—The system has a limited ability to detect
vehicles that are a short distance ahead, off to
the side of your vehicle or moving into your
lane.
— Objects that are difficult to detect such as mo-
torcycles, vehicles with high ground clearance
or an overhanging load are detected late or not
detected at all.
— When driving through curves > page 120.
— When the vehicle is stationary > page 120.


Z\ WARNING
Always pay attention to the traffic around you
when adaptive cruise control is switched on.
As the driver, you are still responsible for your
own speed and the distance to other vehicles.
The adaptive cruise control is used to assist
you. The driver must always take action to
avoid a collision. The driver is always responsi-
ble for braking at the correct time.
— For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather (such
as ice, fog, gravel, heavy rain and hydroplan-
ing). Using the system under these condi-
tions could result in a collision.
— Switch adaptive cruise control off temporari-
ly when driving in turning lanes, on express-
way exits or in construction zones. This pre-
vents the vehicle from accelerating to the
stored speed when in these situations.
— The adaptive cruise control system will not
brake by itself if you put your foot on the ac-
celerator pedal. Doing so can override the
speed and distance regulation.
— Adaptive cruise control does not respond to
people, animals, or crossing or oncoming
objects.
— The function of the radar sensors can be af-
fected by reflective objects such as guard
rails, the entrance to a tunnel, heavy rain or
ice

@) Note
The sensor can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can impair the adaptive
cruise control. Have an authorized Audi dealer
or authorized Audi Service Facility check their
function.
@) Tips
For an explanation on conformity with the
FCC regulations in the United States and the
Industry Canada regulations, see > page 377.

currently set > fig. 117.
> To increase or reduce the distance in incre-
ments, tap the switch upward/downward again.
The distance between the two vehicles will
change in the instrument cluster display.
When approaching a vehicle driving ahead, the
adaptive cruise control system brakes to match
that vehicle&#39;s speed and then adjusts to the set
distance. If the vehicle driving ahead accelerates,
then the adaptive cruise control will also acceler-
ate up to the speed that you have set.
The higher the speed, the greater the distance
=> A\. The Distance 3 setting is recommended.
That is equal to the general recommendation of
“half the speed shown on the speedometer”.
The distances provided are specified values. De-
pending on the driving situation and how the ve-
hicle ahead is driving, the actual distance may be
more or less than these target distances.
If you change the time gaps, the value you have
just set appears briefly in the instrument cluster
display, for example [Eg for Distance 3. This only
occurs if the adaptive cruise control is not cur-
rently shown in the display > page 120, fig. 113.
Distance 1: this setting corresponds to a distance
of 92 feet (28 m) when traveling at 62 mph (100
km/h), or a time distance of 1 second.
Distance 2: this setting corresponds to a distance
of 118 feet (36 m) when traveling at 62 mph
(100 km/h), or a time distance of 1.3 seconds.
Distance 3: this setting corresponds to a distance
of 164 feet (SO m) when traveling at 62 mph
(100 km/h), or a time distance of 1.8 seconds.
Distance 4: this setting corresponds to a distance
of 219 feet (67 m) when traveling at 62 mph
