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.

tivated. There is a temporary malfunction, for ex-
ample the brakes are overheating. Switch the
cruise control system on again later.
Adaptive speed/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:
The adaptive speed/cruise assist (called only
adaptive cruise assist in the vehicle display and in
the rest of the Owner's Manual) consists of a
speed and distance control system. It assists the
driver by both regulating the speed and main-
taining the set distance to the vehicle driving
ahead, within the limits of the system. If the sys-
tem detects a vehicle driving ahead, the adaptive
cruise assist can brake and accelerate your vehi-
cle within the limits 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 automatically brakes to match that
vehicle's speed and then maintains the set dis-
tance as much as possible. As soon as the system
does not detect a vehicle driving ahead, adaptive
cruise assist accelerates up to the set speed.

responsible for controlling the vehicle. The
driver is especially responsible for braking,
starting to drive, controlling the speed, and
maintaining the distance to other vehicles.
— Turn on the adaptive cruise assist only if the
surrounding conditions permit it. Always
adapt your driving style to the current visu-
al, weather, road, and traffic conditions.
— Switch the adaptive cruise assist off tempo-
rarily when driving in turning lanes or high-
way exits. This prevents the vehicle from ac-
celerating to the stored speed when in these
situations.


ZA WARNING
If you press the SETI2) button when driving
at speeds below 20 mph (30 km/h), then 20
mph (30 km/h) will be set because that is the

from the radar sensors and calculates the proba-
bility of a rear-end collision. Within the limits of
the system, an impending collision with the front
of the vehicle can be detected in both urban and
rural speed ranges.
Audi pre sense front is active at speeds of approx-
imately 3 mph (5 km/h) and higher. The system
can respond to pedestrians crossing the street or
going in the same direction of travel 3) at speeds
up to 40 mph (65 km/h). It can also respond to
stationary vehicles at speeds up to 52 mph (85
km/h) as well as to vehicles driving ahead or
stopped vehicles at speeds up to 155 mph (250
km/h).
Early warning/acute warning
The system can recognize various dangerous sit-
uations. The early warning occurs if:
—Avehicle driving ahead brakes suddenly
— Your vehicle is traveling at speeds between ap-
proximately 20 to 50 mph (30 to 85 km/h) and
it approaches a stationary vehicle.
— Your vehicle is traveling at speeds between ap-
proximately 20 to 155 mph (30 to 250 km/h)
and it approaches a vehicle that is clearly trav-
eling more slowly or a vehicle in your direction
of travel that is stopped.
— Ifa crossing pedestrian?) moves into the lane
and you are driving at speeds between approxi-
mately 18 to 40 mph (30 to 65 km/h).

Engine compartment
ere eee)
Special care is required if you are working in the
engine compartment
For work in the engine compartment, such as
checking and filling fluids, there is a risk of in-
jury, scalding, accidents, and burns. For this
reason, follow all the warnings and general
safety precautions provided in the following in-
formation. The engine compartment is a dan-
gerous area on the vehicle. > A\.

ZA WARNING
— Turn the engine off.
— Switch the ignition off.
— Set the parking brake.
— Select the “P” (Park) selector lever position.
— Let the engine cool down.
— Keep children away from the engine com-
partment.
— Never spill fluids on a hot engine. These flu-
ids (such as the freeze protection contained
in the coolant) can catch fire.
— Avoid short circuits in the electrical system.
— Never reach into the radiator fan. The fan is
temperature-controlled and can turn on
suddenly, even when the ignition is switched
off.
— Never open the hood when there is steam or
coolant escaping from the engine compart-
ment, because there is a risk that you could
be burned. Wait until no steam or coolant is
escaping.
— Never open the cap on the coolant expan-
sion tank when the engine is warm. The



cooling system is under pressure.


) Depending on the engine and country

—To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
thick cloth when opening.
— Do not remove the engine cover under any
circumstances. This increases the risk of
burns.
— Due to the risk of electric shock, never touch
the ignition cable or other components in
the electronic high-voltage ignition system
when the engine is running or is starting.
— If a gear is engaged while the vehicle is sta-
tionary and the engine is running, do not
press the accelerator pedal inadvertently.
Pressing the accelerator pedal will cause the
vehicle to move, and this could result in an
accident.
—If inspections or repairs must be performed
while the engine is running, moving compo-
nents (such as the ribbed belt, generator,
and radiator fan) pose an additional risk.
— Set the parking brake first and select the
“P” (Park) selector lever position.
— Always make sure that no parts of the
body, jewelry, ties, loose clothing, and
long hair can be caught in moving engine
components. Before any work, always re-
move any jewelry and/or ties, tie back long
hair, and make sure all clothing fits close
to the body to reduce the risk of anything
becoming caught in engine components.
— Pay attention to the following warnings list-
ed when work on the fuel system or on the
electrical equipment is required.
— Do not smoke.
— Never work near open flames.
— Always have a working fire extinguisher
nearby.
— All work on the battery or electrical system
in your vehicle can result in injuries, chemi-
cal burns, accidents, or burns. Because of
this, all work must be performed only by an
authorized Audi dealer or authorized Audi
Service Facility.
— Limit your exposure to exhaust and chemi-
cals to as short a time as possible.
