Driving
General information
Breaking in
A new vehicle must be broken in for the first 1,000 mi les (1,500 km). Do not dr ive at speeds
t hat will exceed 2/3 of the max imum pe rm itted
engine speed (RPM) for the first 600 miles
(1,000 km), and avoid fu ll acceleration during
this period . You may gradually start increasing
the RPM and the speed between 600 miles
(1,000 km) and 1,000 miles (1,500 km) .
During the first hours of use, the engine has a
higher internal friction than later on when all
moving parts have settled into place with each
other.
How the vehicle is driven d uring the first 1,000
miles (1,500 km) a lso affects the engine quality .
Drive at moderate engine speeds after the initial
break-in per iod, part icu larly when running a cold
eng ine . Th is will reduce eng ine wear and improve
the m ileage.
Do not drive at too
low of an engine speed (RPM).
Shift down if the engine stops running "smooth­ ly". Extremely high eng ine speeds are automati­
cally reduced .
Reducing the risk of vehicle damage
@ Note
When driving on poo r roads, by cu rbs and on
s teep ramps, make su re t hat low-hang ing
compone nts such as the spo ile r and exha ust
system do not come into contact with these
or they could be damaged. This especially ap ­
plies to vehicles with low ground clearance
and veh icles that are heavily loaded.
Driving through water on roads
Note the following to reduce the r isk of vehicle
damage when driv ing through water, for example
on flooded roads :
- The water must not be any higher than the bot­
tom of the vehicle body .
56
-Do not drive faster than walking speed .
A WARNING
After driving through water or m ud, the effec­
tiveness of the brakes may be red uced due to
mo isture on the brake rotors and brake pads.
A few careful brake applications shou ld dry
off the brakes and restore the full braking ef­
fect .
@ Note
Vehicle components such as the engine,
transmission, suspension or electr ica l system
can be severely damaged by driving through
water.
{D Tips
- Determine the depth before driving through
water.
- Do not stop the vehicle, drive in reverse or
switch t he engine off whe n driving through
water.
- Keep in mind that oncom ing vehicles may
create waves that raise the water level and
make it too deep fo r yo ur vehicle to drive
throug h safe ly.
- Avoid driv ing th rough salt water, because
this ca n cause cor rosion .
Economical and environmentally-friendly
driving
The amount o f fuel consumption, the environ ­
mental impact and the wear to the engine,
bra kes and tires depends mostly on your d riving
style. With an ant icipatory and economic driving
sty le, fuel consumpt ion can be reduced by ap­
prox imately 10-15% . The follow ing t ips will help
you conserve the environment and your money at
t h e same time .
Anticipatory dri ving
A vehicle uses the most fuel when accelerating.
When you drive with anticipation, you do not
need to brake as often and so you acce lerate less .
When poss ible, let you r vehicle coast with a
gear
engag ed ,
for examp le, when you not ice that the
next t raff ic light is red.

Audi drive select (drive
settings)
Introduction
A pp lies to: ve hicles w ith Aud i d rive select
Drive select makes it possible to expe rience d if­
fe rent types of vehicle settings in one vehicle.
The driver can select from three modes, Comfort,
Auto and Dynamic , using the
i:l:ta button in the
center console or by using the Infotainment sys­
tem . T his allows you to switch between a sporty
and a comfortab le driving mode, for examp le. In
the Indi vidual mode, the settings can be adjust­
ed to your personal preferences. This makes it
possible to combine sett ings such as a sporty en­
g ine setting w ith light steering.

A WARNING
Using Aud i drive select incorrectly can lead to
coll is ions, other accidents and serious inju­
ries.
Description
App lies to: vehicles with A udi drive se lect
The veh icle setup in each mode depends on the
vehicle's features.
Engine and automatic transmission
Depending on the mode, the engine and auto­
matic transmission respond more quickly or in a
more balanced manner to accelerator pedal
movements.
Suspension control (Audi magnetic ride)*
The suspension control uses sensors to record in­
format ion regarding steering movements, brak­
i ng and acceleration operations by the driver, as
well as information about the road surface, driv­
i ng speed, and load. W ith dr ive se lect, you can
adjust the suspension control to sporty (dynam­
ic ), comfortable (comfort) or balanced (auto).
Steering
The power steering adapts . Indirect steering that
moves eas ily as in comfort mode is espec ially
su ited to long drives on a highway . The dynamic
mode provides sporty, direct steering.
Engine sound*
The engine sound adapts to the current mode
and can be subtle to sporty .
(D Tips
In some models, the maximum vehicle speed
can only be reached in the auto and dynamic
modes .

Selecting the driving mode

-Never install seat covers or replacement
upholstery over the front seatbacks that
have not been specifically approved by
Aud i.
- Never use add itiona l seat cushions that
cover the areas where the s ide airbags in­
flate.
- Damage to the origina l seat covers or to
the seam in the area of the side airbag module must always be repaired immedi­
ately by an authorized Audi dealer.
- The airbag system can deploy only once . Af­
ter an airbag has been deployed, it must be
rep laced with new rep lacement parts de­
signed and approved especially fo r you r
Audi mode l version. Replacement of com­
plete airbag systems or airbag components
must be performed by qualified workshops
only . Make sure that any airbag service ac­
tion is entered in your Audi Warranty
&
Maintenance booklet under AIRBAG RE­
PLACEMENT RECORD.
- For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechn ic circuit
interrupter.
-Work on the pyrotechnic circu it interrupt­
er must only be performed by a qualified
technicians who have the experience, in­
formation and special tools necessary to perform the work safely.
-If the vehicle or the circuit interrupter is
scrapped, all app licab le safety precautions
must be followed.
@ For the sake of the environment
Undep loyed airbag modu les and pretension­
ers might be classified as Perch lorate Materi­
al
-special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlo­
rate . When the veh icle or parts of the re­
straint system including airbag modules and
safety belts with p retensioners are scrapped,
all appli cable laws and regulations must be
observed. Your authorized Audi dealer is fa­
m il iar with these requi rements and we re com­
mend that you have you r dealer per form this
service for you.
Airbag syste m
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs in a crash. For example, using tire-rim
combinations not approved by Audi, lowering the
vehicle, changing the stiffness of the suspension, including the springs, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic cont rol u nit. Some suspension c hanges
can, for example, increase the fo rce leve ls meas­
u red by the sensors and make t he a irbag system
deploy in crashes in which it wou ld not deploy if
the changes had not been made. Other kinds of
changes may reduce the force levels measured by
the sensors and prevent the a irbag from deploy­
ing when it should.
A WARNING
-
Changing the vehicle's suspension including use of unapproved tire-rim combinations can
change Advanced Airbag perfo rmance and in­
crease the risk of serious personal injury in a
crash.
- Never install suspension components that
do not have the same performance charac­
ter istics as the components o riginally instal­
led on your vehicle .
-Never use tire-rim combin ations that have
not been approved by Audi .

-The vehicle should never be lifted or
jacked up from underneath the engine oil
pan, the transmission housing, the front

This could lead to serious damage.
- To avoid damage to the underbody or
chassis frame, a rubber pad must be in­
serted between the floor jack and the lift
points.
- Before driving over a workshop hoist,
check that the vehicle weight does not
exceed the permissible lifting capacity of
the hoist.
- Before driving over a workshop hoist , en­
sure that there is sufficient clearance be­
tween the hoist and low parts of the ve­
