2020 AUDI A3 engine

Driving dynamic

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 functioning correctly.
EDL will switch on again automatically when con-
ditions 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 one of
the following occurs:
— 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
— The ESC, the brake system, or the vehicle elec-
trical system is not functioning

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. There is still
a risk of accidents because the ESC and its
integrated systems cannot always prevent
collisions.
— 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
risk of a collision.



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

94

G) Tips
— The ABS and ASR only function correctly
when all four wheels have a similar wear
condition. Different tire sizes can lead toa
reduction in engine power.
— You may hear noises when the systems de-
scribed are working.
The 0 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
Limiting ESC (sport mode)
—To limit the ESD, press the 0 button briefly.
The B indicator light turns on.
— 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 oF
button for more than three seconds. The B
and Ea indicator lights turn on.

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
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.

Assist systems

Assist systems
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.
