Audi active Lane assist
Description
Applies to: vehicles with Audi active lane assist
The active lane assist (lane departure warning
feature) uses a camera in the windscreen to de­
tect lane markings (subject to general system
limitations). If
you
approach one of the detected
lane markings, the system corrects the steering
to warn you that the vehicle might be about to
cross one of the markings. You can override this
steering input at any time. The steering wheel vi­
brates slightly if
you
cross a lane marking. The vi­
bration warning must be activated beforehand on
the infotainment system. The active lane assist is
functional when it detects a demarcation line on
at least one side of the lane in which you are driv­

ing.

As the system is designed for driving on motor­
ways and other major roads, it is only active

§
above a speed of about 65 km/h (may vary in dif-

£
ferent export markets).
r\i

A WARNING
- The system initiates a corrective steering in­
put to warn the driver that the vehicle is
about to leave the lane. As the driver you
are always responsible for staying in your
own lane.
- The system can assist you to keep the
vehi­

cle in the lane, however it is not capable of
driving on its own. Never take your hands
off the steering wheel.
- In certain situations, e.g. during heavy brak­

ing,
the system may not correct the steer­

ing.

- In certain circumstances, not all of the lane
markings may be detected by the camera. A
corrective steering input can only be
initi­

ated if the system detects a lane marking on
the side in question.
- Variations in the road surface or objects on
the road may be misinterpreted as lane
markings. In this case, the steering may be
corrected unexpectedly or not at all.
- The camera's view might be obstructed, for
example by vehicles travelling in front,
rain,

snow, a lot of water on the
road,
adverse
light
or
dirt on the windscreen. If this hap­

pens,
the active lane assist may not detect

from this area of the windscreen.
- The inside of the camera window is misted up.
In this case, wait for the camera window to de­
mist before switching on the active lane assist
system again.
- Due to the road conditions, the system has not
been able to detect the lane markings for a
long period. Do not switch the active Lane assist
system on again before the lane markings are
discernible.

WARNING
You should switch on the off-road mode or
switch off the ESC/traction control system
(ASR) only if your driving ability and the traf­
fic conditions allow you to do so safely -
dan­

ger of skidding!
- The stabilising function is restricted when
off-road mode is switched on. The driven
wheels may start to
spin,
causing the
vehi­

cle to lose grip, in particular on slippery or
wet roads.
- When the ESC/traction control system
(ASR) is switched off, the vehicle will not be

stabilised.

Brakes
New brake pads
New brake pads do not give full braking effect for
the first 400 km, they must first be "bedded in".
However, you can compensate for the slightly re­
duced braking effect by applying more pressure
on the brake pedal. Avoid placing a heavy load on
the brakes during the running-in period.
Wear
The rate of wear on the brake pads depends a
great deal on how you drive and the conditions in
which the vehicLe is operated. Negative factors

are,
for instance, city traffic, frequent short trips
or hard driving with abrupt starts and stops.
Noises
Brake noise may develop in certain situations, de­
pending on the speed, braking force and ambient
conditions (such as temperature and relative hu­
midity).
Effect of moisture and salt
In certain conditions, such as in heavy
rain,
early
morning dew, or after washing the car or driving
through water, the full braking effect can be de­
layed by moisture (or in winter by ice) on the
discs and brake pads. The brakes should be
< "dried" by pressing the pedal to restore full brak-

R
ing effect.
When you are driving at higher speeds with the
windscreen wipers on, the brake pads are very
briefly brought into contact with the brake discs.
This automatic process which goes unnoticed by
the driver is carried out at regular intervals and is
intended to improve braking response in wet
con­

ditions.
The effectiveness of the brakes can also be
tem­

porarily reduced if the car is driven for some dis­
tance without using the brakes when there is a
lot of salt on the road in winter. The layer of salt
that accumulates on the discs and pads can be
removed with a few cautious brake applications.
Corrosion
There may be a tendency for dirt to build up on
the brake pads and corrosion to form on the discs
if the car is used infrequently, or if
you
only drive
low mileages without using the brakes very

much.

If the brakes are not used frequently, or if corro­
sion has formed on the discs, it is advisable to
clean off the pads and discs by braking firmly a
few times from a moderately high speed
•=> A-

Faults in the brake system
If the brake pedal travel should ever increase
suddenly, this may mean that one of the two
brake circuits has failed. Drive immediately to the
nearest qualified workshop and have the fault

rectified.
On the way to the dealer, be prepared
to use more pressure on the brake pedal and al­
low for longer stopping distances.
Low brake fluid level
Malfunctions can occur in the brake system if the
brake fluid level is too low. The brake fluid level
is monitored electronically.
Brake servo
The brake servo amplifies the pressure you apply
to the brake pedal. It only works when the engine
is running. •

Seat belts

CO

< o rN
iv
rN
t-H
o < 00
Even
at
urban speeds
of
30 km/h to 50 km/h, the
forces acting on the occupants in a collision can
reach the equivalent
of
1 ton (1000 kg)
or
more.
At greater speed these forces are even higher.

Again:
if
the speed doubles, the forces increase
by
a
factor of four.
Passengers who do not wear seat belts are not

"attached"
to the vehicle. In a frontal collision
they will continue to move forward at the speed
their car was travelling just before the impact.
What happens to passengers not wearing
seat belts?

Passengers
not wearing seat belts risk fatal inju­
ries in the event
of
an
accident.

A
rear passenger not wearing
a
seat belt can
be

thrown forwards
In a frontal collision, unbelted passengers will be
thrown forwards and make violent contact with
the steering wheel, dashboard, windscreen, etc

^Fig.
218. Passengers not wearing their belts
risk being thrown out of the car. This could result
in potentially fatal injuries.
The common belief that occupants can brace
their weight with their hands in a minor collision
is false. Even
at
low speeds the forces acting
on

the body in a collision are so great that
it
is not
possible to hold yourself in the seat.
It is also important for the rear passengers
to

wear seat belts, as they could otherwise be
thrown forwards violently in an accident. Rear
passengers who do not use seat belts endanger
not only themselves but also the other occupants

Checking and topping up fluids
A WARNING
- To avoid the risk of being scalded, never
open the bonnet if
you
see steam or coolant
escaping from the engine compartment.
Wait until no steam or coolant can be seen
before opening the bonnet.
- For safety reasons the bonnet must always
be completely closed when the vehicle is

moving.
After closing it always check that it
is properly secured. It should not be possi­
ble to
lift
the front edges of the bonnet.
Should you notice that the bonnet is not
safely secured when the vehicle is moving,
stop the vehicle immediately and close the
bonnet properly, otherwise it could cause an
accident.

Care of vehicle and cleaning
Care of vehicLe and
cleaning
General notes
Regular and careful care helps to maintain the
value of the vehicLe. This may also be one of the
requirements for upholding any warranty claims
in the event of corrosion or paint defects.
Qualified workshops carry stocks of suitable car
care products. PLease
foLLow
the instructions for
use on the packaging.
A WARNING
- Cleaning products and other materials used
for car care can damage health if misused.
- Car care products can contain toxic substan­
ces and must always be kept in a safe place
out of reach of children.

+) For
the sake of the environment
- Please choose care products that are not
harmful to the environment.
- Surplus cleaning materials should not be
disposed of together with ordinary house­
hold waste.
Washing the vehicle
The longer residues like insects, bird droppings,
resinous tree sap or road salt are alLowed to re­
main on the vehicle, the more damage they can
do to the paintwork. High temperatures (for in­
stance in direct sunlight) further intensify the
damage.
Before washing, soak heavy dirt with plenty of
water.
Stubborn dirt, such as bird droppings or resinous
tree sap, is best removed with plenty of water
and a micro-fibre cloth.
After the period when salt is put on the roads,
have the underside of the vehicLe washed thor­
oughly.
High-pressure cleaners
When cleaning the vehicle with a high-pressure
cleaner, always follow the operating instructions
for the equipment. This applies particularly to
the operating pressure and the spraying dis­

tance.
Do not point the spray jet directly at the
seals on the windows, doors, boot lid, bonnet or
panorama sun roof*, or at the tyres, rubber ho­

ses,
insulating material, sensors* or camera
len­

ses*.
Maintain a distance of at least 40 cm.
Do not use a high-pressure cleaner to remove
snow and ice.
Never use high-pressure cleaners with a round-
jet nozzle or "dirt blasters".
The water must not be hotter than 60 °C.
Automatic car washes
Spray the vehicle with water before washing.
Ensure that the windows and panorama sun roof*
are closed and that the windscreen wipers are
switched off. Follow the car wash operator's rules
and recommendations, especially if any accesso­
ries are attached to your vehicle.
If possibLe use a brushless car wash.
Washing by hand
Clean the car with a soft sponge or brush, start­
ing on the roof and working down. Use solvent-
free cleaning agents.
Washing matt-painted vehicles by hand
To avoid damaging the paintwork when washing
the car, first remove any dust, sand and grit. In­

sects,
grease stains and fingerprints are best re­
moved using a special cleaning agent for matt-
painted surfaces.
Apply the product with a micro-fibre cloth. Do
not apply too much pressure to avoid damaging
the paintwork.
Rinse the car thoroughly with water. Then clean
the car with a neutral shampoo and a soft micro-
fibre cloth.
Rinse the car with lots of water again and then
let it dry in the air. Remove any water stains with
a chamois. •
