Basics
Safe driving habits
Please remember -safety first!
This chapter contains important information,
tips, instructions and warnings that you need to
read and observe for your own safety, the safety
of your passengers and others . We have summar­
ized here what you need to know about safety
belts, airbags, child restraints as well as child
safety. Your safety is for us
priority number 1. Al­
ways observe the information and warnings in
this section - for your own safety as well as that
of your passengers.
The information in this section applies to all
model versions of your vehicle. Some of the fea­
tures descr ibed in this sections may be standard
equipment on some models, or may be optional
equipment on others. If you are not sure, ask
your authorized Audi dealer.
A WARNING
- Always make sure that you follow the in­
structions and heed the WARNINGS in this
Manual. It is in your interest and in the in­
terest of your passengers .
-
-Always keep the complete Owner's Litera­
ture in your Audi when you lend or sell your
vehicle so that this important information
will always be available to the driver and
passengers.
- Always keep the Owner's literature handy so
that you can find it easily if you have ques­
tions.
Safety equipment
The safety features are part of the occupant re­
straint system and work together to help reduce the risk of injury in a wide variety of accident sit­
uations.
Your safety and the safety of your passengers
should not be left to chance. Advances in tech­
nology have made a var iety of features available
to help reduce the risk of injury in an accident.
Driving safety
The following is a list of just a few of the safety
features in your Audi:
- sophisticated safety belts for driver and all pas-
senger seat ing pos itions,
- safety belt pretensioners,
- safety belt force limiters for the front seats,
- safety belt height adjustment systems for the
front seats,
- front airbags,
- knee airbags for the front seats
- side airbags in the front seats and outer rear
seats,
- side curtain airbags,
- special LATCH anchorages for child restraints,
- head restraints for each seating position,
- adjustable steering column.
These individual safety features, can work to­ gether as a system to help protect you and your
passengers in a w ide range of accidents . These
features cannot work as a system if they are not
always correctly adjusted and correctly used.
Safety is everybody's responsibility!
Important things to do before driving
Safety is everybody 's job! Vehicle and occupant
safety always depends on the informed and care­
ful driver .
For your safety and the safety of your passen­
gers,
before driving always:
.,. Make sure that all lights and signals are operat­
ing correctly .
.,. Make sure that the tire pressure is correct.
.,. Make sure that all windows are clean and afford
good visibility to the outside .
.,. Secure all luggage and other items carefully
c:c.> page 68, c:c.> page 73 .
.,. Make sure that nothing can interfere with the
pedals.
.,. Adjust front seat, head restraint and mirrors
correctly for your height.
.,. Instruct passengers to adjust the head re­
straints according to their height.
.,. Make sure to use the right child restraint cor­
rectly to protect children

Driving safety
-Never leave your vehicle unattended espe­
cially with the rear lid left open. A child
could crawl into the vehicle through the lug­
gage compartment and close the rear lid be­
coming trapped and unable to get out . Be­
ing trapped in a vehicle can lead to serious
personal injury.
- Never let children play in or around the vehi­
cle.
- Never let passengers ride in the luggage compartment. Vehicle occupants must al­
ways be properly restrained in one of the ve­
hicle's seating positions.
- Air circulation helps to reduce window fog­
ging . 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 label is lo­
cated on the driver's side B·pillar. The tire pressure label lists the recommended 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 man­
ufactured. For recommended tire pressures
for normal load conditions, please see chap­
ter ¢
page 247.
Tie-downs
The luggage compartment is equipped with four
tie-downs to secure luggage and other items .
Use the tie-dow ns to secure your cargo properly
¢ page 135, Loading the luggage compartment .
In a coll ision, the laws of physics mean that even
smaller items that are loose in the vehicle will
become heavy missiles that can cause serious in­
jury . Items in the vehicle possess energy 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
136
weight of the item. This means that the weight
of the item would suddenly be about
200 lbs. (90 kg) . You can imagine the injuries
that a 200 lbs. (90 kg) item flying freely through
the passenger compartment could cause in a col­
lision like th is.
A WARNING
Weak, damaged or improper straps used to
secure items to tie-downs can fail during hard
braking or in a collision and cause serious per­
sonal injury.
- Always use suitable mounting straps and
properly secure items to the tie-downs in
the luggage compartment to help prevent items from shifting or flying forward as dan­
gerous missiles.
- Never attach a child safety seat tether strap
to a tie-down.

Reporting Safety Defects
Applicable to U.S.A.
If you believe that your vehicle
has a defect which could cause a
crash or could cause injury or
death, you should immediately in­
form the National Highway Traffic Safety Administration (NHTSA) in
addition to notifying Audi of
America, Inc.
If NHTSA receives similar com­plaints, it may open an investiga­
tion, and if it finds that a safety
defects exists in a group of
vehicles, it may order a recall and remedy campaign. However,
NHTSA cannot become involved in
individual problems between you,

Trailer load distribution
Be sure the load in the trailer is held securely in
p la ce to prevent it from sh ifting forward, back­
ward or sideways.
Never allow a passenger to ride in a trailer¢.&.
in Driving instructions on page 204.
Engine cooling system
Towing a trailer makes the engine work harder . It
is important that the cool ing system's perform­
ance is up to the addit ional load. Make sure that
the cooling system has enough fluid.
Tire pressure
When towing a trailer, inflate the tires of your
veh icle to the cold tire pressure listed under "Full
load " on the label located on the driver's side B­
pillar (vis ible when the door is open). Inflate
trailer tires to trailer and tire manufacturers'
specif ications.
Lights
Check to make sure both vehicle and trailer lights
are working proper ly.
Safety chains
Be sure trailer safety chains are properly connect­
ed from the trailer to the hitch on the vehicle.
Leave enough slack in the chains to permit turn­
in g corners . When you install safety cha ins, make
sure they wi ll 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 separat ion
from the hitch.
Adjusting the Audi drive select
Make sure the vehicle is on a level surface before
hitching up the trailer and before adjusting the
tongue we ight. The vehicle must be in
auto or
comfort driving mode and not ra ised
¢ page 106, 9Q) .
Make sure that the vehicle is lowered. In Info­
tainment, select:
I CARI function button > lower
control button .
Trailer mode
If you must drive under poor road conditions, you
can raise the vehicle
after coupling the trailer or
after adjusting the tongue weight¢ page 108.
(D Note
-Changes in temperature or load can affect
the height of the vehicle.
- Always select auto or comfort mode. Other­
w ise, the tong ue load specified for your ve­
hicle will no longer be applicable .
Driving instructions
Driving with a trailer always requires extra care
and consideration.
T o obtain the best possible handling of veh icle
and trailer, p lease note the following:
.,. Do not tow a loaded trailer when your car itself
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 tra iler with an empty car results
in a highly unstab le 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 control.
This means that the tow vehicle shou ld be loaded
to the extent possib le and permissib le, while
keeping the trailer as light as possible under the
cir cumstances . Whenever poss ible, transfer
some cargo to the luggage compartment of the
tow veh icle while observing tongue load require­
ments and vehicle load ing conside rations.
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the r ig. Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or wind .,._

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 your authorized Audi dealer or a
qualified workshop. Read and follow the instruc­
tions for use on the packaging.
A 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
- Preferably use environmentally-friendly
products when buying cleaning agents.
- Do not dispose of leftover cleaning and care
products with household trash.
Car washes
The longer deposits remain on the vehicle, the
more the surface can be damaged. High temper­
atures such as those caused by sunlight increase
the damaging effects .
Before washing, wet heavy deposits with plenty
of water.
Stubborn deposits such as bird droppings or tree
sap are best removed with plenty of water and a
microfiber cloth.
Also, wash the underside of your vehicle once
road salt stops being used for the season.
Pressure washers
When washing your vehicles with a pressure
washer, always follow the operating instructions
provided with the pressure washer. This is espe­
cially important in regard to the pressure and
spraying distance . Do not aim the spray directly
at seals on side windows, doors, the hood, the
206
rear lid or the sunroof* or at tires, rubber hoses,
insulating material, sensors* or camera lenses*.
Keep a distance of at least 16 inches (40 cm) .
Do not remove snow and ice with a pressure
washer.
Never use rotary nozzles or high pressure noz­
zles.
The water temperature must not be above 140 °F
(60 °C).
Automatic car washes
Spray off the vehicle before washing.
Make sure that the windows and roof* are closed
and the windshield wipers are
off . Follow instruc­
tions 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 remains
stationary and the washing equipment moves
around the vehicle when washing and drying. Car
washes that move the vehicle through the car
wash using a chain are not recommended.
Washing by hand
Clean the vehicle starting from the top and work­
ing down using a soft sponge or cleaning brush.
Use solvent-free cleaning products.
Washing vehicles with matte finish paint by
hand
To avoid damaging the paint when washing, first
remove dust and large particles from your vehi­
cle. Insects, grease spots and fingerprints are
best removed with a special cleaner for matte
finish paint.
Apply the product using a microfiber cloth. To
avoid 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 sham my. ..,..
