2019 AUDI E-TRON brake

Trailer towing


— Note that the vehicle will lower automatical-
ly at certain speeds if you have lifted the

vehicle manually.

@) Note
— Select the Audi drive select* comfort mode.
Otherwise, the tongue load specified for
your vehicle will no longer be applicable.
— 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.
@ 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 try to
“straighten out” the trailer by accelerating.
122
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.

ZA 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.

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.


C) Note
Before driving downhill a long distance ona
steep hill, decrease your speed and use the
braking effect of recuperation > page 90. This
reduces the load on the brakes.
@) Tips
The brake lights turn on when the brakes are
applied automatically.

specify a speed limit.
— Except for the road network, which is re-
corded in the navigation system’s map infor-
mation, certain functions may not be availa-
ble.
— 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.
— Specific settings are stored automatically in
the active personal profile.

During predictive control), the adaptive cruise
assist uses data from the efficiency assist. The
system adapts the speed set in the adaptive
cruise assist to the speed limits that are detected
and the layout of the road. After that, the system
accelerates up to the speed that was set.
After switching on the ignition, the availability of
predictive control is indicated by a message when
the adaptive cruise assist is first activated.
The displays depend on the vehicle equipment.
Requirements
— The adaptive cruise assist must be actively reg-
ulating > page 141.
— The system can only react to speed limits that
are 20 mph (30 km/h) or higher.
Display in the speedometer
The display in the speedometer is not available in
all layouts*.
@ The marking shows the set speed (regulated
speed that was set by the driver or by predic-
tive control).
@ The red band shows the difference between
the speed limit and the set speed that is set.
@® The gray band shows if the vehicle speed is
planned to drop below the set speed due to
the road layout.
Overriding control
The driver can override the predictive control at
any time by pressing the accelerator or brake
pedal. If the system changes the vehicle speed to
adapt to speed limits, you can change the speed
using the lever > page 141, fig. 111.

along route setting to reduce the risk of an
accident.


ZA\ WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 123.
— Pay attention to traffic and the area around
your vehicle when predictive control is
switched on. The driver is always responsible
for assessing the traffic situation.
— The system does not consider “right of way”
rules and does not respond to traffic lights,
so lack of driver attention in these situations
can increase the risk of an accident.
— The speed when driving through curves may
be different from what you as a driver would
do or may not be suitable for the weather
and road conditions. If necessary, apply the
brakes and reduce the selected speed to be

maintained in the Adjustment to curves

@) Tips
— Predictive control can exceed or drop below
the maximum permitted speed. The driver
is responsible for adhering to the permitted
speed limit.
— The traffic signs on the road always take pri-
ority over the display. The driver is always
responsible for adhering to the regulations
applicable in the country where the vehicle
is being operated.
— Ifa speed limit is detected, the marking @
of the set speed limit will be adjusted even
if the adaptive cruise assist is not actively
regulating.
— You may temporarily fall below or exceed
the set speed due to recuperation.
— Control by the system depends on which
adaptive cruise assist driving program is set
or on the selected Audi drive select* mode.
— After switching on the ignition and first
driving onto a freeway or similar road with-
out a speed limit, the system will regulate
the speed to 80 mph (130 km/h), Then
the system adjusts to the last speed set by
the driver.
— There is no adaptation to speed limits when
driving through highway interchanges and
when driving on or off the expressway.
— The system can fail to provide control or the
control may be faulty if the values from the
camera-based traffic sign recognition* are
incorrect or the navigation system map data
is outdated.
— When route guidance is switched on, the
system adapts to the route provided by the
navigation system. Driving without route
guidance or leaving a route can result in
faulty control.
— Specific settings are stored automatically in
the active personal profile.

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 and distance control assists the driver in
controlling the speed and the set distance to the
vehicle driving ahead. If the system detects a ve-
hicle driving ahead, the adaptive cruise assist can
brake and accelerate your vehicle within the lim-
its of the system. On open roads with no traffic, it
functions like a cruise control system. The stored
speed is maintained. When approaching a vehicle
driving ahead, the adaptive cruise assist auto-
matically brakes to match that vehicle's speed
and then maintains the set distance as much as
possible. As soon as the system does not detect a
vehicle driving ahead, adaptive cruise assist ac-
celerates up to the set speed.
The additional lane guidance assists the driver
with corrective steering in order to stay in the
lane. You can adjust if the adaptive cruise assist
will provide support with lane guidance
= page 142, Switching lane guidance on and off.
In stop-and-go traffic and in traffic jams, the ve-
hicle 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 adjust the speed based on traffic
and road conditions > page 137, Predictive con-
trol.


Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 123.

Fig. 107 Example: driving into a curve
In some situations, the adaptive cruise assist
function is limited and you must assume control
of the vehicle when necessary, for example by ap-
plying the brakes.
— If a vehicle that was already detected @ turns
or changes lanes, the adaptive cruise assist will
react to the vehicle ahead of it @).
— When driving into a curve > fig. 107 and out of
a curve, the adaptive cruise assist 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 adaptive cruise assist works with the vari-
ous sensors and cameras in the vehicle. Vehi-
cles can only be detected once they are within
the area and range covered by the sensors
=> page 124, fig. 96.
— 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 adaptive cruise assist does not react toa
stationary vehicle in the same lane if the
139

Driver assistance

system expects that you can easily drive around
the stationary vehicle by turning the steering
wheel.
— The adaptive cruise assist may not react to sta-
tionary obstacles, such as the end of a traffic
jam, especially at high speeds.
— The adaptive cruise assist 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 adaptive cruise assist does not respond to
people, animals, or objects that are crossing or
approaching from the opposite direction.
