tion from which the cross traffic is approaching.
The indicator in the upper display only appears
when the parking aid is activated. For vehicles
with peripheral cameras only in the Front and
Front corner camera views. The display only ap-
pears in the instrument cluster > fig. 123 when
the Driver assistance display is open in the on-
board computer > page 14.
— Warnings: the message Cross traffic! Bo can
warn you of critical cross traffic when driving
forward. There may also be an audible signal.
— Automatic brake activation: if you do not react
to a warning, a brief braking by the system can
warn you of a potential collision with an ap-
proaching object when driving forward at
speeds up to approximately 6 mph (10 km/h).
Switching the intersection assistant on and
off
— The system can be switched on and off in the
MMI & page 130.

ized Audi dealer or authorized Audi Service Facili-
ty immediately to have the malfunction correct-
ed.

Z\ WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 127.
— The intersection assistant will not provide
alerts about people and cannot warn you
about every type of approaching objects,
such as cyclists. Always monitor the traffic

162

as well as the vehicle's surroundings with di-
rect eye contact.
— The system may not react if vehicles are ap-
proaching very fast.
G) Tips
For an explanation on conformity with the
FCC regulations in the United States and the
Industry Canada regulations, see > page 295.

Emergency assist
Applies to: vehicles with emergency assist
General information
Within the limits of the system, emergency assist
can detect inactivity from the driver. In these in-
stances, the system will warn the driver, assume
control of the vehicle if necessary, and bring the
vehicle automatically to a stop in the lane.
Regardless of the speed, the emergency assist is
automatically available when the adaptive cruise
assist* is activated. When the adaptive cruise as-
sist* is deactivated, the system is only available
at speeds above approximately 40 mph
(65 km/h).
Emergency assist functions
Measures may be initiated in stages. The vehicle
can be controlled with the limits of the system.
The measures depend on the dangerous situation
and the vehicle equipment:
— Visual and audio warnings
— Vehicle control
— Reduction of vehicle speed in stages
— Lowers the volume of the Infotainment system
— Tugs on the safety belt
— Activates the brakes
— The emergency flashers will activate either
while the vehicle is still in motion or once it is
stationary (depending on your vehicle's produc-
tion date).
— Audi pre sense preemptive safety measures are
triggered > page 155
— The brakes are applied until the vehicle is sta-
tionary

Checking and Filling

> Read the brake fluid level on the brake fluid res-
ervoir > page 242, fig. 157. The brake fluid lev-
el must be between the MIN and MAX markings
>A.
The brake fluid level is monitored automatically.
Message
Ga I © Brakes: stop vehicle and check brake
fluid level
Stop the vehicle and check the brake fluid level.
See an authorized Audi dealer or authorized Audi
Service Facility for assistance.
Changing the brake fluid
Brake fluid should be changed at regular inter-
vals. Have the brake fluid changed by an author-
ized Audi dealer or authorized Audi Service Facili-
ty. The authorized Audi dealer or authorized Audi
Service Facility will inform you of the replace-
ment intervals.

Z\ WARNING
— If the brake fluid level is below the MIN
marking, it can impair the braking effect and
driving safety, which increase the risk of an
accident. Do not continue driving. See an au-
thorized Audi dealer or authorized Audi
Service Facility for assistance.
— If the brake fluid is old, bubbles may form in
the brake system during heavy braking. This
could impair braking performance and driv-
ing safety, which increases the risk of an ac-
cident.
— The brake fluid in your vehicle must meet
the standard VW 501 14 and is available at
an authorized Audi dealer or authorized
Audi Service Facility. If this brake fluid is not
available, another high-grade brake fluid of
equivalent quality may be used, and it must
meet the U.S. Federal Motor Vehicle Stand-
ard (FMVSS) 116 DOT 4, Class 6.

@) Note
— If the brake fluid level is above the MAX
marking, brake fluid may leak out over the
edge of the reservoir and result in damage
to the vehicle.
244
— Do not allow any brake fluid to come into
contact with the vehicle paint, because it
will corrode the paint.

Glossary of tire and loading
terminology
Accessory weight
means the combined weight (in
excess of those standard items
which may be replaced) of auto-
matic transmission, power steer-
ing, power brakes, power win-
dows, power seats, radio, and
heater, to the extent that these
items are available as factory-in-
stalled equipment (whether in-
stalled or not).
Aspect ratio
means the ratio of the height to
the width of the tire in percent.
Numbers of 55 or lower indicate a
low sidewall for improved steer-
ing response and better overall
handling on dry pavement.
Bead
means the part of the tire that is
made of steel wires, wrapped or
reinforced by ply cords and that is
shaped to fit the rim.
Bead separation
means a breakdown of the bond
between components in the bead.
Cord
means the strands forming the
plies in the tire.
Cold tire inflation pressure
means the tire pressure recom-
mended by the vehicle manufac-
turer for a tire of a designated
size that has not been driven for
more than a couple of miles (kilo-
meters) at low speeds in the three
hour period before the tire pres-
sure is measured or adjusted.
Curb weight
means the weight of a motor ve-
hicle with standard equipment in-
cluding the maximum capacity of
fuel, oil, and coolant, air condi-
tioning and additional weight of
optional equipment.
Extra load tire
means a tire designed to operate
at higher loads and at higher in-
flation pressures than the corre-
sponding standard tire. Extra load
tires may be identified as “XL”,
“xl”, “EXTRA LOAD”, or “RF” on
the sidewall.

Production options weight
means the combined weight of
those installed regular production
options weighing over 5 lbs.
(2.3 kg) in excess of those stand-
ard items which they replace, not
previously considered in curb
weight or accessory weight, in-
cluding heavy duty brakes, ride
levelers, roof rack, heavy duty
battery, and special trim.
Radial ply tire
means a pneumatic tire in which
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 251, 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)
means the speed at which a tire is
designed to be driven for extend-
ed periods of time. The ratings
range from 93 mph (150 km/h)
to 186 mph (298 km/h) > table

position and the total weight of
any luggage in the vehicle. If you
tow a trailer, the weight of the
trailer hitch and the tongue
weight of the loaded trailer must
be included as part of the vehicle
load.
The Gross Axle Weight Rating
(“GAWR’”) is the maximum load
that can be applied at each of the
vehicle’s two axles.
The fact that there is an upper
limit to your vehicle’s Gross Vehi-
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas-
sengers in the vehicle or passen-
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as
luggage.
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating
are listed on the safety compli-
ance sticker label located on the
driver’s side B-pillar.


Z\ WARNING
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per-
sonal injury, and even death.
—Carrying more weight than
your vehicle was designed to
carry will prevent the vehicle
from handling properly and in-
crease the risk of the loss of
vehicle control.
—The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.
—Tires ona vehicle that has
been overloaded can fail sud-
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
—Always make sure that the to-
tal load being transported -
including the weight of a trail-
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle’s
Gross Vehicle Weight Rating.

height and width of the inside of the car
wash.
—To reduce the risk of paint damage, do not
wash the vehicle in direct sunlight.
—To reduce the risk of damage, do not wash
decorative decals* with a pressure washer.
—To reduce the risk of damage to the surface,
do not use insect removing sponges, kitchen
sponges, or similar items.
— When washing matte finish painted vehicle
components:
ZA WARNING
—To reduce the risk of accidents, only wash
the vehicle when the ignition is off and fol-
low the instructions from the car wash oper-
ator.
—To reduce the risk of cuts, protect yourself
from sharp metal components when wash-
ing the underbody or the inside of the wheel
housings.
— After washing the vehicle, the braking effect
may be delayed due to moisture on the
brake rotors or ice in the winter. This in-
creases the risk of an accident. The brakes
must be dried with a few careful brake appli-
cations.
— To reduce the risk of damage to the sur-
face, do not use polishing agents or hard
wax.
— Never use protective wax. It can destroy
the matte finish effect.
@) Note — Do not place any stickers or magnetic
signs on vehicle components painted with
matte finish paint. The paint could be
damaged when the stickers or magnets
are removed.

— If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors.
Power folding exterior mirrors* must only
be folded in and out using the power folding (@) For the sake of the environment
function.
—To reduce the risk of damage to the rims
and tires, compare the width between the
wheels on your vehicle with the distance be-
tween the guide rails in the car wash.
Only wash the vehicle in facilities specially de-
signed for that purpose. This will reduce the
risk of dirty water contaminated with oil from
entering the sewer system.
—To reduce the risk of damage, compare the
height and width of your vehicle with the
