Driving dynamic

brake assist system may react with increased sen-
sitivity.
Anti-Slip Regulation (ASR)
ASR reduces drive power when the drive wheels
begin spinning and adapts the power to the road
conditions. This makes it easier to start, acceler-
ate and drive up hills.
Electronic Differential Lock (EDL)
The EDL applies the brakes to wheels that are
slipping and transfers the drive power to the oth-
er wheels. This function is not available at higher
speeds.
In extreme cases, EDL automatically switches off
to keep the brake on the braked wheel from over-
heating. The vehicle is still working correctly. EDL
will switch on again automatically when condi-
tions have returned to normal.
Power steering
The ESC can also support vehicle stability
through steering.
Selective wheel torque control
Selective wheel torque control is used when driv-
ing on curves. Braking is targeted toward the
wheels on the inside of the curve as needed. This
allows more precise driving in curves.
Automatic post-collision braking system
The automatic post-collision braking system can
help to reduce the risk of sliding and of addition-
al collisions after an accident. If the airbag con-
trol module detects a collision, the vehicle is
braked by the ESC.
The vehicle does not brake automatically if:
— The driver presses the accelerator pedal, or
— the braking force generated by the pressed
brake pedal is greater than the braking force
that
would be initiated by the system, or
— the ESC, the brake system or the vehicle electri-
cal system are not functioning.

physical laws. This is especially important on
slippery or wet roads. If the systems begin
acting to stabilize your vehicle, you should
immediately alter your speed to match the
road and traffic conditions. Do not let the in-
creased safety provided tempt you into tak-
ing risks. This could increase your risk of a
collision.
— Please note the risk of a collision increases
when driving fast, especially through curves
and on slippery or wet roads, and when driv-
ing too close to objects ahead. The ESC and
its integrated systems cannot always pre-
vent collisions - there is still a risk of acci-
dents!
— Accelerate carefully when driving on
smooth, slippery surfaces such as ice and
snow. The drive wheels can spin even when
these control systems are installed and this
can affect driving stability and increase the



ZA WARNING
— The ESC and its integrated systems cannot
overcome the limits imposed by natural

risk of a collision.
G) Tips
— The ABS and ASR only function correctly
when all four wheels have a similar wear
condition. Different tire sizes can lead to a
reduction in engine power.
— You may hear noises when the systems de-
scribed are working.
The So button is located above the selector lev-
er in the center console.

The ESC is automatically switched on when the
ignition is switched on. It may make sense in
some situations to limit the ESC so that the
wheels can spin:
— Rocking the vehicle to free it when it is stuck
— Driving in deep snow, on unpaved ground, or
with snow chains
— Driving downhill while braking on loose ground
— Driving with axle articulation
Limiting ESC (Offroad mode)
—To limit the ESD, press the £20 button briefly.
The B indicator light turns on.

Driving dynamic

— To completely reactivate the ESC stabilization
function, press the button again. The indicator
light turns off.
Switching off ESC
—To switch off the ESC, press and hold the or
button for more than three seconds. The B
and Ea indicator lights turn on.
— To completely reactivate the ESC stabilization
function, press the button again. The indicator
lights turn off.

ZA WARNING
— When the ESC is switched off or limited,
there will be no vehicle stabilization or it will
be limited. The driving wheels could spin
and the vehicle could swerve, especially on
slick or slippery road surfaces, which in-
creases the risk of an accident.
— Because of the increased risk of an accident,
only drive with the ESC switched off or Limit-
ed when it is necessary. Reactivate the ESC
as soon as possible.
@ Tips
If malfunctions occur in other systems or cer-
tain driver assist systems are active, the ESC
must be switched on by the system. In these
cases, the ESC is automatically switched on
and cannot be limited or switched off with the
button.
I Ss / B & Stabilization control (ESC/
ABS): malfunction! See owner's manual

There is a malfunction in the ABS or EDL. This al-
so causes the ESC to malfunction. The brakes still
function with their normal power, but ABS is not
active.
Drive to an authorized Audi dealer or authorized
Audi Service Facility immediately to have the
malfunction corrected.

Trailer towing

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
Certain requirements must be met when towing
a trailer.

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 > @.

Z\ WARNING
— Never mount a "weight-distributing" or
"load-balancing" trailer coupler as the trailer
hitch. The vehicle was not designed for
these types of trailer hitches. The trailer
hitch can malfunction and the trailer can
break off from the vehicle.
— If the trailer is equipped with electronic
brakes, these brakes cannot be activated by
a factory-installed control system, which in-
creases the risk of an accident.
—To reduce the risk of injury, always remove
the ball hitch mount if no trailer is mount-
ed
® 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

Never exceed the maximum permitted weights
=> page 264.
In some scenarios, the load in trailer mode can
be reduced due to the permitted towing weight.
You can drive up larger inclines if you are not us-
ing the maximum towing capacity.
The towing capacities given only apply to eleva-
tions up to 3,200 ft (1,000 m) above sea level. As
the elevation increases, the engine power de-
creases due to the decreasing air pressures. This
reduces the hill climbing ability and towing ca-
pacity. For every additional 3,200 ft (1,000 m),
the maximum permitted towing weight must be
reduced by approximately 10%. The permitted
towing weight is the combined weight of the
(loaded) vehicle and the (loaded) trailer.
101

83A012721BA
Trailer towing

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 transitioning to hills, trailers may tilt or
sway sooner than when driving on a level surface.
If small swaying movements have already occur-
red, you can stabilize the trailer by firmly braking
immediately. Never try 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 13. Shift to a higher gear in a timely man-
ner.

ZA WARNING
Constant braking causes the brakes to over-
heat and substantially reduces braking per-
formance, increases braking distance or caus-

es complete failure of the brake system.

General information
Safety precautions

ZA WARNING
— As the driver, you are always completely re-
sponsible for all driving tasks. The assist
systems cannot replace the driver's atten-
tion. Give your full attention to driving the
vehicle, and be ready to intervene in the
traffic situation at all times.
— Activate the assist systems only if the sur-
rounding conditions permit it. Always adapt
your driving style to the current visual,
weather, road, and traffic conditions.
— Loose objects can be thrown around the ve-
hicle interior during sudden driving or brak-
ing maneuvers, which increases the risk of
an accident. Store objects securely while
driving.
— For the assist systems to be able to react
correctly, the function of the sensors and
cameras must not be restricted. Note the in-
formation on sensors and cameras
=> page 105 or > page 106.

@ Tips
— Pay attention to applicable local regulations
relating to driving tasks, leaving space for
emergency vehicles, vehicle distance, speed,
parking location, wheel placement, etc. The
driver is always responsible for following
the laws that are applicable in the location
where the vehicle is being operated.
— You can cancel a steering or braking inter-
vention by the system, by braking or accel-
erating noticeably, steering, or deactivating
the respective assist system.
— Always check the assist systems settings be-
fore driving.

System limitations
ZA WARNING
— The use of an assist system cannot over-
come the natural laws of physics. A collision
cannot be prevented in certain circumstan-
ces.

— Warnings, messages, or indicator lights may
not be displayed or initiated on time or cor-
rectly, for example, if vehicles are approach-
ing very fast.
— Corrective interventions by the assist sys-
tems, such as steering or braking interven-
tions, may not be sufficient or they may not
occur. Always be ready to intervene.
G) Tips
— Due to the system limitations when detect-
ing the surrounding area, the systems may
warn or intervene unexpectedly or too late
in certain situations. The assist systems may
also interpret a driving maneuver incorrectly
and then warn the driver unexpectedly.


— The systems may not function as expected
in unusual driving situations, such as driving
offroad, on unpaved roads, on loose ground,
on inclines, or on grooves in the road.
— The systems may not function correctly in
unclear traffic situations, such as turning
lanes, exit ramps, construction zones, rises
or dips that obstruct visibility, intersections,
toll stations, or city traffic.
—In trailer mode, some assist systems may be
limited, may not react as usual, or may be
unavailable. Please refer to the instructions
for towing a trailer located in > page 101.
— If accessories have been mounted on the
steering wheel, the ability for the steering
systems to react may be limited.

Assist systems

@) Tips
— The coverage areas of the sensors > fig. 86
are diagrams and do not represent a true-
to-scale image of the sensor ranges. The ra-
dar sensors are designed to detect the left
and right adjacent lanes when the road
lanes
are the normal width.
— Make sure all the sensors are clean and free
of snow and ice, and that the visual fields
are not covered by stickers, deposits, or any
other obstructions, because this may impair
the function of the systems. Follow the in-
formation about cleaning > page 236.
— Do not use a license plate bracket different
from the one installed by the factory in the
front of the vehicle, because it may impair
the function of dependent systems.
— The sensors can shift from an accident,
manual force, impacts, or from damage to
the radiator grill, bumper, wheel housing,
or underbody. Do not continue using the as-
sistance systems if the sensors have shifted,
because this is unsafe. Have an authorized
Audi dealer or authorized Audi Service Fa-
cility check their function.
— The function of the sensors may be limited
when light and visibility conditions are poor,
for example when driving into a tunnel,
when there is glare, or when there are re-
flective objects.
— External ultrasonic sensors, such as those in
other vehicles, can interfere with the sen-
sors.
—The side area ©)* is detected and evaluated
when passing. There may have been
changes to the surrounding area after
switching the ignition off and on again, af-
ter opening the doors, or if the vehicle is left
stationary for a period of time. In this case,
the area will appear black until the area has
been detected and evaluated.

Driving information

Driving information
Speed warning system
Applies to: vehicles with speed warning system
The speed warning system helps the driver to
stay below a specified maximum speed. A warn-
ing threshold can be set for this purpose.
Once the speed slightly exceeds the stored
threshold, the speed warning system will alert
the driver with an indicator in the instrument
cluster and a warning tone. Once the speed drops
below the stored maximum speed, the indicator
will turn off.
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.
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.

Driver assistance

Driver assistance
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
you when the cruise control system is in op-
eration. As the driver, you are always respon-
sible 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
hydroplaning), because this increases the
risk of an accident.
— 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
Before driving downhill a long distance ona
steep hill, decrease your speed and select a
lower gear. This makes use of the engine brak-
ing effect and relieves the brakes.
@) Tips
The brake lights turn on when the brakes are
applied automatically.
