Driver assistance

Warning stage
If you activate a turn signal and the display flash-
es, side assist is warning about objects that have
been classified as critical.
Depending on the vehicle equipment and other
driver assistance systems, the display may also
flash if you have not activated a turn signal. If
you are approaching a detected lane marker line
and it appears you will be leaving the lane, the
display will warn you about detected vehicles
that are classified as critical. You can also be
warned with corrective steering > page 176,
Lane departure warning.
Detection range
The radar sensors are designed to detect the left
and right adjacent lanes when the road lanes are
the normal width. In some situations, the display
may turn on even though there is no vehicle lo-
cated in the area that is critical for a lane change.
For example:
— If the lanes are narrow or if you are driving on
the edge of your lane. If this is the case, the
system may have detected a vehicle in another
lane that is not adjacent to your current lane.
— If you are driving through a curve. Side assist
may react to a vehicle that is in the same lane
or one lane over from the adjacent lane.
— If side assist reacts to other objects (such as
roadside structures like guard rails).

ZA\ WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 150.
— The display may not appear on time when
vehicles are approaching or being passed
very quickly.

@ Tips
— If the window glass in the driver's door or
front passenger's door has been tinted, the
display in the exterior mirror may be incor-
rect.
— The coverage areas of the sensors > fig. 132
are diagrams and do not represent a true-
to-scale image of the sensor ranges.
— The system complies with United States FCC
regulations and ISED regulations
> page 341.

Checking and Filling

> Close the cover on the positive terminal.
> Close the hood > page 276.

ZA WARNING
— Never connect a charging cable or jump
start cable directly to the 12 Volt vehicle
battery. Only use the connections in the en-
gine compartment > page 286.
— A highly explosive mixture of gases can form
when charging batteries. Only charge the
battery in well-ventilated areas.
— A drained battery can freeze at tempera-
tures around 32 °F (0 °C). Do not charge or
use a frozen or thawed battery. If ice forms,
the battery housing can crack and battery
electrolyte can leak out, which increases the
risk of an explosion and chemical burns.
Contact an authorized Audi dealer or author-
ized Audi Service Facility for more informa-
tion.
— Do not connect or disconnect the charging
cable while charging because this increases
the risk of an explosion.

of calcium. Always add window cleaner to the wa-
ter. When the outside temperatures are cold, an
anti-freezing agent should be added to the water
so that it does not freeze.
Messages
|} Please add washer fluid
Fill the washer fluid for the windshield washer
system and the headlight washer system* when
the ignition is switched off.
CG) Note
—The concentration of anti-freezing agent
must be adjusted to the vehicle operating
conditions and the climate. A concentration
that is too high can lead to vehicle damage.
— Never add radiator anti-freeze or other addi-
tives to the washer fluid.
— Do not use a glass cleaner that contains
paint solvents, because this could damage
the paint.

Care and cleaning

Care and cleaning
General information
Regular, proper care helps to maintain your vehi-
cle's value. It can also be a requirement when
submitting warranty claims for corrosion damage
and paint defects on the body.
The required cleaning and care products can be
obtained from an authorized Audi dealer or au-
thorized Service Facility. Read and follow the in-
structions for use on the packaging.

ZA\ WARNING
— Using cleaning and care products incorrectly
can be dangerous to your health.
— Always store cleaning and care products out
of reach of children to reduce the risk of poi-

soning.

@ For the sake of the environment
— Purchase environmentally-friendly cleaning
products if possible.
— Do not dispose of cleaning and care prod-
ucts with household trash.
Car washes
The longer that deposits such as insects, bird
droppings, tree sap or road salt remain on the ve-
hicle, the more the surface can be damaged. High
temperatures such as those caused by sunlight
increase the damaging effect.
Before washing, rinse off heavy deposits with
plenty of water.
Stubborn deposits such as bird droppings or tree
sap are best removed with plenty of water anda
microfiber cloth.
Also, wash the underside of your vehicle once
road salt stops being used for the season.
Pressure washers
When washing your vehicle with a pressure wash-
er, always follow the operating instructions pro-
vided with the pressure washer. This is especially
important in regard to the pressure and spraying
distance. Do not aim the spray directly at the
310
seals on the side windows, doors, hood, luggage
compartment lid, or sunroof*, or at tires, rubber
hoses, insulating material, sensors*, camera
lenses*, or the laser scanner*. Keep a distance of
at least 16 inches (40 cm).
Plug-in hybrid drive: Do not direct the stream of
water towards the wall mount clip*.
Do not remove snow and ice with a pressure
washer.
Never use cone nozzles or high pressure nozzles.
The water temperature must not be above 140 °F
(60 °C).
Automatic car wash
Spray off the vehicle before washing.
Make sure that the windows and roof* are closed
and the windshield wipers are off. Make sure that
the vehicle is still able to roll during the washing
process in the car wash. Follow instructions from
the car wash operator, especially if there are ac-
cessories attached to your vehicle.
If possible, use car washes that do not have
brushes.
Washing by hand
Clean the vehicle starting from the top and work-
ing downward using a soft sponge or cleaning
brush. Use solvent-free cleaning products.
Washing vehicles with matte finish paint by
hand
To reduce the risk of damaging the paint when
washing, first remove dust and large particles
from your vehicle. Insects, grease spots, and fin-
gerprints are best removed with a special cleaner
for matte finish paint.
Apply the product using a microfiber cloth. To re-
duce the risk of damaging the paint surface, do
not use too much pressure.
Rinse the vehicle thoroughly with water. Then
clean using a neutral shampoo and a soft micro-
fiber cloth.
Rinse the vehicle thoroughly again and let it air
dry. Remove any water residue using a chamois. >
