The neck heating has three levels . If you turn the
knob to the right, the neck heating switches on
¢ fig. 65. The LEDs above the seat symbol indi­
cate the ventilation level. Turn the knob to the
left to reduce ventilat ion. To switch off the neck
heating, keep turning the knob to the left until
no LEDs are turned on .
When the power top is closed, the neck heating
switches automatically from setting 3 to setting
2 after approx imately six minutes.
A WARNING
- Individuals with reduced sensitiv ity to pain
or temperature could develop burns when
using the neck heat ing . To reduce the risk of
in ju ry, these individuals shou ld no t use neck
heat ing.
- The output from the neck hea ting may be­
come very hot temporarily if the air vents in
the seats
qfig . 64 are covered by clothing
or simi lar ob jects when the system is

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.

Avoid full acceler ation
You sho uld rare ly t rave l a t t he maxim um vehicle
speed . High speeds cause a disproportionately
h igh increase in fuel consumption, emissions and
traffic noise . Slower driving saves fuel.
Reduce idling time
It pays off to stop the eng ine, for example when
at ra ilroad crossings or traffi c lights w ith longer
red lights . Stopping the engine for 30 -40 sec­
onds already saves more fuel than the amount of
extra fuel needed to restart the engine.
I t takes a very long time in idle to wa rm the en­
gine up to operating tempera ture . Wea r and
emissions are especially high in the warm -up
p hase . Therefore, you should begin driving im ­
mediately after starting the engine. Avoid high
RPMs while do ing th is.
Hav e ma intenanc e performed r egularly
By having maintenance performed regu lar ly on
your vehicle, you can he lp to reduce fuel con ­
sumption before yo u even start to drive. The
maintenance condition of your vehicle not only
affects traffic safety and long-term va lue but al­
so impacts
fu el con sumpt ion .
A poorly maintained engine can lead to fuel con ­
sumpt ion that is 10% higher than norma l.
A lso check the
o il l evel when refueling . The oil
consumpt ion
depends large ly on the engine load
and speed. It is normal for the oil consumption
of a new eng ine to reach its lowest point only af­
ter a certain amount of use. Therefore, the oil
consumption can only be properly judged after
approx imately 3,000 m i (S,000 km) have been
driven.
Avoid short trips
The engine and exhaust clean ing system must
reach their opt imal
op erating temp eratur e to ef­
fective ly reduce consumpt ion and emiss ions.
A co ld engine uses a disproportionately h igh
amount of fuel. The eng ine reaches operating
temperature and consumpt ion normalizes only
afte r approx imately
2.5 miles (4 km) .
Driving
@ Note
Do not leave engine idling unattended after
start ing. If warning lights sho uld come on to
i ndicate improper operation, they would go
unheeded. Extended idling also produces
heat, which could resu lt in overheating or
other damage to the veh icle o r other proper­
ty.
@ Note
- Have your ve hicle ma intained properly and
in accordance w ith the service recommenda­
tions i n your Warranty
& Main tenance book­
let. La ck of prope r mai nte nan ce as we ll as
imp rope r use of t he ve hicle will impa ir the
function of the em iss ion cont ro l system and
co uld lead to damage .
- Do not alte r or remove any compone nt o f
t he Emission Contro l System unless ap ­
proved by the man ufacturer .
- Do not alte r or remove any dev ice, s uch as
heat shields, switc hes, ignition wires,
valves, which are designed to protect your
vehicle's Emission Contro l System and other
impo rtant ve hicle components.

Driving
Steering
Adjusting the steering wheel position
The steering wheel position is fully adjustable up
and down and forward and back .
Fig. 6 6 Lever on th e steering column
.., Tilt the lever~ fig . 66 downward ~ .&.
... Bring the steering wheel into the desired posi­
tion .
... Push the lever against the steering column un­
til it is secure.
A WARNING
Incorrect use of the steering wheel adjust­
ment and an incorrect seating position can
cause se rious injuries .
- Only adjust the steering column when the vehicle is stat io nary so that you do not lose
contro l of the ve hicle.
-
-Adjust the driver's seat or steering wheel so
that there is at least a 10 in (25 cm) d is­
tance between your c hest an d the steering
wheel.
If you do not mainta in this dis tan ce,
you will not be p roper ly protec ted by t he air­
bag system.
- If your physical character istics preven t you
from sit ting at least 1 0 in (25 cm) or more
away from the steering wheel, see if an a u­
tho rized Aud i dea le r or a uthorized Audi
Service Facility can provide adapters that
will help.
- If your face is leve l w ith the steering
wheel,
the a irbag does not prov ide as much protec­
t ion during a collision. A lways make sure
that the steering wheel is level with your
chest.

-Always hold the steering wheel with your hands in the 9 o'clock and 3 o'clock pos i­
tions to reduce the risk of injury if the airbag
deploys .
- Never hold the steering wheel in the 12
o'clock position or with both hands on the
rim or the center of the steering wheel. Ho ld ing the steer ing whee l incorrect ly sig­
nificant ly increases the risk of injury to the
hands, a rms and head if the airbag deploys.
