The sou nd of the engine is adapted to these­
lec ted mode and ranges from subtle to sporty.
(D Note
- Make sure there is eno ugh clearance
above and below the veh icle when park­
i ng. The height of the vehicle can change
once it is parked due to temperature
fluctuations, changes to the load condi ­
tions and changes to the driving modes,
which can affect clearance.
- When transporting the vehicle on a car
carrier, train, ship or by other means, on­
ly tie the vehicle down at the running
surface of the tires, which is the outer
circumference. Securing the vehicle at
the axle components, suspension struts
or tow ing eyes is not permitted because
the pressure in the air suspension struts
can change d uring transport. The vehicle
may not be sec ured s uff icient ly if this
happens.
-If you are going to tow a trailer, you
must activate the trailer ope rat ion mode
¢page 208 .
@ Tips
-In some mode ls, the m axim um vehicle
speed can on ly be reached in the Auto
and Dynami c modes.
- Se lecting the Dynami c mode results in
sporty shifting characteristics . The S
gear position engages automatically .
- In vehicles with sport differential*, the
D ynamic mode is deactivated when tow ­
ing a trai ler .
- In vehicles that have dynamic steering*,
operating noise is heard when starting or

Driving Safely
General notes
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
summarized here what you need to know
about safety belts, airbags, child restraints as
well as child safety. Your safety is for us
priori­
ty number 1.
Always 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
features described 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 interest of your passengers.
- Always keep the complete Owner's Liter­
ature in your Audi when you lend or sell
your vehicle so that this important infor­
mation 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
questions.
Safety equipment
The safety features are part of the occupant
restraint system and work together to help
reduce the risk of injury in a wide variety of
accident situations.
Your safety and the safety of your passengers
should not be left to chance. Advances in
technology have made a variety of features
available to help reduce the risk of injury in an accident.
The following is a list of just a few of
the safety features in your Audi:
- sophisticated safety belts for driver and all
passenger seating positions,
- 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 re-
straints,
- 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 wide range of accidents .
These features cannot work as a system if
they are not always correctly adjusted and cor­
rectly used.
Safety is everybody's responsibility!
Important things to do before driving
Safety is everybody 's job! Vehicle and occu ­
pant safety always depends on the informed and careful driver .
For your safety and the safety of your passen ­
gers,
before driving always:
.. Make sure that all lights and signals are op­
erating correctly.
.. Make sure that the tire pressure is correct .
.. Make sure that all windows are clean and af­
ford good visibility to the outside .
.. Secure all luggage and other items carefully
q page 64, q page 61 .
.. 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 . .,..

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.
Gj) Tips
-Air circulation helps to reduce window fogging. Stale air escapes to the outside
through vents in the trim panel. Be sure
to keep these slots free and open .

Driving Safely 135
-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 247.
Tie-downs
The luggage compartment is equipped with
four tie-downs to secure luggage and other
items.
Use the tie-downs to secure your cargo prop­
erly<>
page 134, 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 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 collision like this.
A WARNING
Weak, damaged or improper straps used
to secure items to tie-downs can fail dur­
ing hard braking or in a collision and cause
serious personal injury.
-Always use suitable mounting straps and properly secure items to the tie-downs in
.

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
qpage 102, ~CD .
Make sure that the vehicle is lowered. In Info­
tainment, select:
ICARI function button> Low­
er
control button.
If you must drive under poor road conditions,
you can raise the vehicle
after coupling the
trailer or
after adjusting the tongue weight
qpage 104.
- 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.
Trailer towing
Driving instructions
Driving with a trailer always requires extra
care 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
drive at the maximum permissible speed. Re­
duce your speed even more if load, weather or
wind conditions are unfavorable -particularly
when going downhill .
Reduce vehicle speed
immediately if the trail­
er shows the slightest sign of swaying .
Do not
try to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds
for vehicles towing trailers are lower than for
regular vehicles . ..,..

Tires
General notes
Tires may be the least appreci­
ated and most abused parts of
a motor vehicle.
Tires may be the least appreci­
ated and most abused parts of
a motor vehicle. Tires are, how­
ever, one of the most important
parts of a vehicle, particularly
considering the comparatively
small patch of rubber on each
tire that assures that all-impor­
tant 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 safely handle, avoiding
damage from road hazards and
regularly inspecting tires for
damage including cuts, slashes
irregular wear and overall con­
dition are the most important
things that you can do to help avoid sudden tire failure includ­
ing tread separation and blow­
outs.
Avoiding damage
If you have to drive over a curb
or similar obstacle, drive very
slowly and as close as possible
at a right angle to the curb.
Always keep chemicals includ­
ing grease, oil, gasoline and
brake fluid off the tires.
Inspect the tires regularly for
damage (cuts, cracks or blis­
ters, etc.). Remove any foreign
bodies embedded in the treads.
Storing tires
Mark tires when you remove
them to indicate the direction
of rotation. This ensures you to
be able to mount them correct­
ly when you reinstall 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.
