also responds to the driving behavior of the
veh icle ahead in a more conservative or sporty
manner.
Engine sound*
The sound of the engine is adapted to the se­
l ected mode and ranges from subtle to sporty.
(D Note
- Make sure there is enough clearance
above and below the vehicle when park­
i ng. The height of the vehicle can change
once it is parked due to temperature
fluctuations, changes to the load cond i­
tions and changes to the dr iv ing modes,
which can affect clearance.
- When transporting the veh icle on a car
carrier, tra in, ship or by other means, on­
ly tie the veh icle down at the running
surface of the tires, which is the outer
circumference. Secur ing the vehicle at
the axle components, s uspension struts
or towing eyes is not permitted because
the pressure in the air suspension struts
can change during transport . The vehicle
may not be sec ured s ufficient ly if this
happens.
- If you are going to tow a trailer, you
must activate the trailer operation mode
C? poge 212.
@ Tips
- In some models, the maximum vehicle
speed can only be reached in the
auto
and dynamic modes.
- Selecting the
dynamic mode results in
sporty shifting characteristics . The S
gear position engages automatically.
- In vehicles that have dynamic steering*,
operating noise is heard when starting or
stopping the engine. Th is does not indi­
cate a problem.

142 Driving Safely
-Always distribute the load as evenly as
possible.
- Place heavy objects as far forward in
the luggage compartment as possible.
- Never exceed the Gross Axle Weight Rat­
ing or the Gross Vehicle Weight Rating
specified on the safety compliance stick­
er on the left door jamb. Exceeding per­
missible weight standards can cause the
vehicle to slide and handle differently.
- Please observe information on safe driv­
ing
q page 135.
A WARNING
-
To help prevent poisonous exhaust gas
from being drawn into the vehicle, always keep the rear lid closed while driving.
- Never transport objects larger than those fitting completely into the luggage
area because the rear lid cannot be fully
closed.
- If you absolutely must drive with the rear
lid open , observe the following notes to
reduce the risk of poisoning:
- Close all windows,
- Close the power roof,
- Open all air outlets in the instrument
panel,
- Switch off the air recirculation,
- Set the fresh air fan to the highest
speed.
A WARNING
Always make sure that the doors, all win­
dows, the power roof and the rear lid are
securely closed and locked to reduce the
risk of injury when the vehicle is not being
used.
- After closing the rear lid, always make
sure that it is properly closed and locked.
- Never leave your vehicle unattended es­ pecially with the rear lid left open. A
child could crawl into the vehicle through
the luggage compartment and close the
rear lid becoming trapped and unable to
get out . Being trapped in a vehicle can
Lead to serious personal injury .
-
-Never let children play in or around the
vehicle.
- Never let passengers ride in the luggage
compartment. Vehicle occupants must
always be properly restrained in one of
the vehicle's seating positions .
(D Tips
-Air circulation helps to reduce window
fogging. Stale air escapes to the outside
through vents in the trim panel, on the
Left side of the Luggage compartment.
Be sure to keep these slots free and
open .
- The tire pressure must correspond to the
load . The tire pressure is shown on the
tire pressure label. The tire pressure la­
bel is located on the driver's side B-pillar.
The tire pressure Label lists the recom­
mended cold tire inflation pressures for
the vehicle at its maximum capacity
weight and the tires that were on your
vehicle at the time it was manufactured.
For recommended tire pressures for nor­
mal Load conditions, please see chapter
<=> page 252 .
Tie -downs
The luggage compartmen t is equipped wi th
four tie-downs to secure luggage and o ther
items.
Use the tie-downs to secure your cargo p rop­
erly
c> page 141, Loading the luggage com­
partment.
In a collision, the laws of physics mean that
even smaller items that are loose in the vehi­
cle will become heavy missiles that can cause
serious injury. Items in the vehicle possess en ­
ergy which vary with vehicle speed and the
weight of the item. Vehicle speed is the most significant factor.
For example, in a frontal collision at a speed
of 30 mph (48 km/h), the forces acting on a 10-lb (4 .5 kg) object are about 20 times the
normal weight of the item. This means that
the weight of the item would suddenly be

Trailer load distribution Be sure the load in the trailer is held securely
in place to prevent it from shifting forward,
backward or sideways.
Never allow a passenger to ride in a trailer
¢ .&. in Driving instructions on page 214.
Engine cooling system
Towing a trailer makes the engine work hard ­
er . It is important that the cooling system's
performance is up to the additional load .
Make sure that the cooling system has enough
fluid.
Tire pressure
When towing a trailer, inflate the tires of your
vehicle to the cold tire pressure listed under
"Full load" on the label located on the driver's
side B-pillar (visible when the door is open).
Inflate trailer tires to trailer and tire manufac­
turers' specifications.
Lights
Check to make sure both vehicle and trailer
lights are working properly.
Safety chains Be sure trailer safety chains are properly con­
nected from the trailer to the hitch on the ve­
hicle . Leave enough slack in the chains to per­
mit turning corners . When you install safety
chains, make sure they will not drag on the
road when you are driving.
The chains should cross under the trailer
tongue to prevent it from dropping in case of
separation from the hitch .
Adjusting the Audi drive select Make sure the vehicle is on a level surface
be­
fore
hitching up the trailer and before adjust ­
ing the tongue weight. The vehicle must be in
auto or comfort driving mode and not raised
¢page 110, ~CD .
Make sure that the vehicle is lowered. In Info ­
tainment, select:
ICARI function button> low­
er control button .
Trailer towing 213
If you must drive under poor road conditions,
you can raise the vehicle
after coupling the
trailer or
after adjusting the tongue weight
¢ page 112.
@ Note
- Changes in temperature or load can af­
fect the height of the vehicle.
- Always select auto or comfort mode.
Otherwise, the tongue load specified for
your vehicle will no longer be applicable.
Driving instructions
Driving with a trailer always requires extra
core and consideration.
To obtain the best possible handling of vehicle
and trailer, please note the following:
.,. Do not tow a loaded trailer when your car it­
self is not loaded .
.,. Be especially careful when passing other
vehicles.
.,. Observe speed limits.
.,. Do not drive at the maximum permissible
speed .
.,. Always apply brakes early .
.,. Monitor the temperature gauge.
Weight distribution
Towing a loaded trailer with an empty car re­
sults in a highly unstable distribution of
weight. If this cannot be avoided, drive at very
low speeds only to avoid the risk of losing
steering control.
A "balanced" rig is easier to operate and con­
trol. This means that the tow vehicle should be loaded to the extent possible and permissi­
ble, while keeping the trailer as light as possi­
ble under the circumstances . Whenever possi­
ble , transfer some cargo to the luggage com­
partment of the tow vehicle while observing
tongue load requirements and vehicle loading
considerations.
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the rig. Do not .,.

Vehicle care and
cleaning
General information
Regular, proper care helps to maintain your
vehicle 's value. It can also be a requirement
when subm itting warranty claims for corro ­
sion damage and paint defects on the body .
The required cleaning and care products can be obtained from your authorized Audi dealer
or a qualified workshop. Read and follow the
instructions for use on the packaging .
A WARNING
-Us ing cleaning and care products incor­
rectly can be dangerous to your hea lth .
- Always store cleaning and care products
o ut of reach of children to reduce the r is k
of po ison ing.
@) For the sake of the environment
- Preferably use environmentally-friendly
products when buying cleaning agents .
- Do not d ispose of leftover cleaning and
ca re p rod ucts with household trash .
Car washes
-
The longer that deposits such as insects, bird
droppings , tree sap o r road salt rema in on the
ve hicle, the more the surface can be dam­
aged. High temperatures such as those
caused by s unligh t increase the corrosive ef­
fect.
Before washing, wet heavy deposits w ith p le n­
ty of water.
A lso, wash the underside of your vehicle once
road salt stops be ing used for the season .
Pressure wa sher s
When washing your vehicles w ith a pressure
washer, always follow the operating instruc­
tions provided w ith the pressure washer. Th is
is especially important in rega rd to the pres ­
sure and spray ing distance . Do not aim the
spray d irectly at seals on side w indows, doors, the hood, the
rear lid o r the sunroof* or at
tires, rubber hoses, insu lating material, sen­
sors * or camera lenses* . Keep a d istance of at
least 16 inches (40 cm).
Do not remove snow and ice with a pressu re
washer .
Never use rota ry no zzles or high pressure noz­
z les.
T he water temperature must not be above
140 °F (60 °C) .
Automatic car washes
Spray off the ve hicle before washing.
Make sure that the windows and roof * are
closed and the winds hield wipers are off . Fo l­
l ow instructions from the car wash operator,
especially if there are accessories attached to
your vehicle.
If possible, use car washes that do not have
brushes .
Only use car washes where the vehicle re ­
mains stationary an d the washing equipment
moves aro und the vehicle when washing and
drying. Car washes that move the vehicle
t h rough the car wash using a chain are not
recommended.
Wa shing by hand
Clean the ve hicle starting from the top and
working down using a soft sponge or cleaning
brush. Use solvent-free clean ing products .
Washing vehicles with matte finish paint
by hand
To avoid damaging the paint when washing,
first remove dust and large particles from
your vehicle. Insects, grease spots and finger­
pr ints are best removed with a spec ial cleane r
for matte finish paint .
Apply the product us ing a microfiber cloth. To
avo id 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 mi-
crofiber cloth. ..,.

Tires
General notes
Tires may be the least appreciated and most
abused parts of a motor vehicle .
Tires may be the least appreciated and most
abused parts of a motor vehicle . Tires are,
however, one of the most important parts of a
vehicle, particularly considering the compara­
tive ly small patch of rubber on each tire that
assures that all -important contact between
you, your vehicle and the road.
Maintaining the correct tire pressure, making
sure that your vehicle and its tires do not have
to carry more weight than they can safe ly han­
d le, avoiding damage from road hazards and
reg ularly inspecting t ires for damage includ­
ing cuts, slashes irregu la r wear and overall
condition are the most important things that
you can do to he lp avoid sudden tire failure in­
cluding tread separation and blowouts.
A vo idin g dama ge
I f you have to drive over a curb or similar ob­
stacle, drive very slow ly and as close as possi ­
ble at a right angle to the curb.
A lways keep chem icals including grease, oil,
gasoline and b rake fluid off the tires.
Inspect the tires regularly for damage (cuts,
cracks or bl isters, etc.). Remove any foreign
bod ies embedded in the treads.
St orin g tire s
Mark tires when you remove them to indicate
the direction of rotation . Th is ensures you to
be ab le to mount them correctly when you re­
install them.
When removed, the wheels or tires should be
stored in a cool, dry and preferably dark place .
Store tires in a vertical position if they are not mounted on rims, in a horizontal position if
they are mounted on rims. N
ew tir es
New t ires have to be broken in¢&,. .
The tread depth of new t ires may vary, accord­
ing to the type and make of t ire and the tread
pattern .
Hidden damag e
Damage to tires and r ims is often not readily
vis ible . If you notice unusual vibrat ion or the
vehicle pulls to one s ide, th is may ind icate
that one of the t ires has been damaged . T he
t ir es must be checked immed iate ly by an au­
tho rized Aud i dea le r or q ualified wor kshop.
Unidirecti onal t ires
A un idirectional tire can be identified by ar­
rows on the sidewall, that po int in the direc­
t ion the t ire is designed to rotate. You must
fol low the specified direction of rotation . This
is necessary so that these tires can develop
their optimum characteristics regarding grip, road noise, wear and hydrop laning resistance.
For more information ¢
page 2 77.
A WARNING
-New tires or tires that are old, worn or
damaged cannot provide maximum con­
trol and braking ability .
-
-New tires tend to be slippery and must
be broken in . To reduce the risk of losing
control, a collision and ser ious personal
injuries, drive w ith special ca re for the
fi rst 350 m iles (560 km).
- Driving with worn or damaged tires can lead to loss of control, sudden tire fail­
ure, including a blowou t and sudden de­
flation, c rashes and serious personal in­
juries . Have worn or damaged tires re­
p laced immediate ly.
- Tires age even if they are not being used
and can fai l sudden ly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith special care and at low
speed.

-Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age .
