2020 AUDI E-TRON brake

Trailer towing

— Attachments retrofitted on the vehicle may
cause damage, especially on the trailer
hitch ball head. In cases of damage, have
the function checked by an authorized Audi
dealer or authorized Audi Service Facility.
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.
Driving with a trailer
Driving with a trailer requires extra caution.
Speed
Adhere to the legal speed limits. Follow the legal
regulations that are applicable in the country
where you are operating the vehicle.
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
firmly braking immediately. Never attempt to
“straighten out” the trailer by accelerating.
Reduce the speed and use the recuperation brak-
ing effect > page 92 to relieve the brakes > 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.

Z\ WARNING
Constant braking causes the brakes to over-
heat and can substantially reduce braking per-

126


formance, increase braking distance, or cause
complete failure of the brake system.

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
Before driving downhill a long distance ona
steep hill, decrease your speed and use the
braking effect of recuperation > page 92. This
reduces the load on the brakes.
@) Tips
The brake lights turn on when the brakes are
applied automatically.

— The functions depend on the navigation da-
ta* being up-to-date and correct identifica-
tion by the traffic sign recognition*.
— The system only detects traffic signs that
specify a speed limit.
— The display in the instrument cluster is
based on the units of measurement used for
speed in the country where the vehicle is be-
ing operated. As a result, a display of 50 in
the instrument cluster can mean either
km/h or mph, depending on the country.
— Except for the road network, which is re-
corded in the navigation system’s map infor-
mation, certain functions may not be availa-
ble.

ority over the display. The driver is always
responsible for adhering to the regulations
applicable in the country where the vehicle
is being operated.
— When a route is planned using the naviga-
tion system*, then system displays messag-
es based on an assumed route. Without
route guidance, the system displays mes-
sages based on an assumed route.
— The wording of the message may vary de-
pending on the selected Audi drive select*
mode and the selected gear. No messages
are displayed when in the "S" driving pro-

Adaptive cruise assist
General information
Applies to: vehicles with adaptive cruise assist

Depending on the vehicle equipment, the adap-
tive cruise assist may consist of the following
functions:
Within the limits of the system, the adaptive
speed assist assists the driver in controlling the
speed and the set distance to the vehicle driving
ahead. If the system detects a vehicle driving
ahead, the adaptive speed assist can brake and
accelerate your vehicle within the limits of the
system. On open roads with no traffic, it func-
tions like a cruise control system. The stored
speed is maintained. When approaching a vehicle
driving ahead, the adaptive speed assist auto-
matically brakes to match that vehicle's speed
and then maintains the set distance as much as
possible. Once the system does not detect a vehi-
cle driving ahead, adaptive speed assist will ac-
celerate up to the set speed.
The additional lane guidance assists the driver
with corrective steering in order to stay in the
142

lane. You can adjust if the adaptive cruise assist
will provide support with lane guidance
= page 146, Switching lane guidance on and off.
In stop-and-go traffic, the vehicle may brake to a
full stop and then may also start driving again
automatically under certain conditions.
Applies to: Vehicles with efficiency assist: Predic-
tive control can adapt the vehicle speed to the
conditions > page 147, Predictive control.
ZX WARNING
Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 127.

of the vehicle when necessary, for example by ap-
plying the brakes.
— Ifa vehicle that was already detected @ turns
or changes lanes, the system will react to the
vehicle ahead of it (2).
— When driving into a curve > fig. 104 and out of
a curve, the system may react to a vehicle in the
adjacent lane and apply the brakes. You can
override the system by pressing the accelerator
pedal briefly.
— The system works with the various sensors and
cameras in the vehicle. Vehicles can only be de-
tected once they are within the area and range
covered by the sensors > page 128, fig. 94.
— When driving around tight curves, a vehicle
driving ahead that was previously detected may
no longer be detected, and the adaptive cruise
assist may accelerate unexpectedly.
— The system does not react to a stationary vehi-
cle in the same lane if it expects that you can
easily drive around the stationary vehicle by
turning the steering wheel.
— The system cannot react to stationary objects,
such as vehicles at the end of a traffic jam, es-
pecially when traveling at high speeds.
— 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 vehicles with an overhanging load, may be
detected late or not detected at all.
— The system does not respond to people, ani-
mals, or objects that are crossing or approach-
ing from the opposite direction.
