Driver assistance

Steering intervention request
If Audi active lane assist intervenes multiple
times when no steering activity is detected, the
steering intervention request will provide a warn-
ing using audio and visual signals, such as BE.
Take over the steering and keep your hands on
the steering wheel so that you will be ready to
steer at any time. The system may no longer be
ready to provide warnings after a short time, and
it will only become active again later.
If the driver does not take over steering, Audi ac-
tive lane assist will be switched off.
Behavior when a turn signal is active
Applies to: vehicles with side assist: The system
will not warn you if you activate a turn signal be-
fore crossing the lane marker line. In this case, it
assumes that you are changing lanes intentional-
ly.
Applies to: vehicles with side assist: If the turn
signal is activated, Audi active lane assist is
ready, and a lane change has been classified as
critical by lane assist due to vehicles traveling be-
side you or due to approaching vehicles, then a
noticeable corrective steering movement will oc-
cur briefly before exiting the lane. This will at-
tempt to keep your vehicle in the lane.

ZX WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 117.
— The system warns the driver that the vehicle
is leaving the lane using corrective steering.
The driver is always responsible for keeping
the vehicle within the lane.
— Corrective steering may not occur at all in
certain situations, such as during heavy
braking. Always be ready to intervene.

G) Tips
— Always keep your hands on the steering
wheel so you can be ready to steer at any
time. The driver is always responsible for
adhering to the regulations applicable in
the country where the vehicle is being oper-
ated.

— The system does not provide any corrective
steering or steering wheel vibrations if it de-
tects that you are passing another vehicle.
— The image in the Driver assistance display
only appears if it was opened in the on-
board computer > page 16.

the ply cords that extend to the
beads are laid at substantially
90 degrees to the centerline of
the tread.
Recommended inflation
pressure
see > page 238, Cold tire infla-
tion pressure.
Reinforced tire
means a tire designed to operate
at higher loads and at higher in-
flation pressures than the corre-
sponding standard tire. Rein-
forced tires may be identified as
“XL”, “xl”, “EXTRA LOAD”, or “RF”
on the sidewall.

Rim
means a metal support for a tire
or a tire and tube assembly upon
which the tire beads are seated.
Rim diameter
means nominal diameter of the
bead seat. If you change your
wheel size, you will have to pur-
chase new tires to match the new
rim diameter.
Rim size designation
means rim diameter and width.
Rim width
means nominal distance between
rim flanges.
Sidewall
means that portion of a tire be-
tween the tread and bead.
Speed rating (letter code)

depending on the model.
Use the tire pressure specified for
a normal vehicle load when the
vehicle is partially loaded > table
on page 247. If driving the vehi-
cle when fully loaded, you must
increase the tire pressure to the
maximum specified pressure > A.
Checking and correcting tire
pressure
>Check the tire pressure at least
once per month and also check it
before every long drive.
> Always check the tire pressure
when the tires are cold. Do not
reduce the pressure if it increas-
es when the tires are warm.
>Refer to the sticker > fig. 168
for the correct tire pressure.
>Correct the tire pressure if nec-
essary.
>Save the changed tire pressure
> page 254.
> Check the pressure in the spare
tire (compact spare tire)*. Al-
ways maintain the maximum
temperature that is specified for
the tire.

Z\ WARNING
Always adapt the tire pressure
to your driving style and the ve-
hicle load.
—Overloading can lead to loss of
vehicle control and increase
the risk of an accident. Read
and follow the important safe-
ty precautions in > page 248.
—The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con-
trol.
—Incorrect tire pressure increas-
es tire wear and has a negative
effect on driving and braking
behavior, which increases the
risk of an accident.

@) Note
Replace lost valve caps to re-
duce the risk of damage to the
tire valves.
(*) For the sake of the envi-
ronment
Tire pressure that is too low in-
creases fuel consumption.
