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.
Warming up/cooling down
Applies to: RS models
By warming up/cooling down the engine carefu l­
ly, you can help reduce unnecessary stra in o n
your veh icle when driving in a sporty sty le .
72
The tires only reach t heir full road ho ld ing capa ­
bility once they have warmed up under load.
Yo ur vehicle also has an afte r-run cooli ng fea ­
tu re . Howeve r, cooling down is st ill import ant.
The eng ine and t he brakes as we ll as the exhaust
system and the transmission become very hot
when driving in a sporty style. Before you shut
the veh icle off, you should cool down the vehicle
by driving a few miles at low speeds with light ac­
ce leration .
Driving through water on roads
Note the following to reduce the risk of veh icle
damage when dr iving throug h wate r, fo r example
o n flooded roads:
-The water must not be any higher than the bot ­
tom of the vehicle body .
-Do not drive faster than walk ing speed .
A WARNING
After driving thro ugh water or m ud, the effec­
tiveness of t he b rakes may be reduced due to
mo istu re o n the bra ke rotors and brake pads.
A few ca reful br ake app lica tions sho uld d ry
off the bra kes and restore the fu ll b raking ef ­
fect.
@ Note
-Vehicle components such as the e ng ine,
t ra nsmiss ion, sus pens io n or elect rical sys ­
tem can be severely damaged by d riving
throug h water.
-Alw ays sw itch the S tart/Stop system* o ff
when driving thro ugh wa ter
r=;, page 79.
(j) Tips
-De ter mine the dep th before dr iving throug h
w ate r.
-Do not stop the vehi cle, d rive in reverse or
switch t he e ngine off whe n driving through
water .
-Keep in mind that o ncom ing vehicles may
c re ate w aves th at r aise the wa ter level and
make i t too deep for yo ur vehicle to drive
throug h safe ly.

Driving
When not being used, a roof rack should be re­
moved to decrease the wind resistance of the ve­
hicle. This will save you approximately 12% fuel
at speeds from 62
-75 mph (100 -120 km/h).
Save energy
The engine drives the generator, which generates
electricity; the fuel consumption also increases
with the demand for electricity. Therefore, switch
electrical equipment
off when you no longer
need it. Examples of equipment that uses a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating* .
(D Note
-Do not leave engine idling unattended after
starting. If warning lights should come on
to indicate improper operation, they would
go unheeded. Extended idling also produces
heat, which could result in overheating or
other damage to the vehicle or other prop­ erty.
- Have your vehicle maintained properly and
in accordance with the service recommenda­
tions in your Warranty
& Maintenance book­
let . Lack of proper maintenance as well as
improper use of the vehicle will impair the
function of the emission control system and
could lead to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such as
heat shields, switches, ignition wires,
valves, which are designed to protect your
vehicle's Emission Control System and other
important vehicle components.
@ Tips
The consumpt ion estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehicle
load and speed, road and weather conditions,
trip length, etc.

Steering
Adjusting the steering wheel position
The steering wheel position is fully adjustable up
and down and forward and back.
Fig . 83 Steering column : steering column adjustment lever
.. Tilt the lever -c> fig. 83 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 serious injuries.
- Only adjust the steering column when the veh icle is stationary so that you do not lose
control of the vehicle.
-
-Adjust the driver's seat or steer ing wheel so
that there is at least 10 inches
(25 cm) dis­
tance between your chest and the steering
wheelr::!>page250, fig. 217. If you do not
maintain this distance, the airbag system
will not be able to provide its full protec­ tion.
c:> page 250, fig. 217.
- If your physical characteristics prevent you
from sitting at least 10 inches
(25 cm) or
more away from the steering wheel, see if
an authorized Audi dealer or authorized
Audi Service Facility can provide adapters that will help.
- If your face is level with the steering wheel,
the airbag does not provide as much protec­
tion during a collision. Always make sure
that the steering wheel is level with your
chest.

-Always hold the steering whee l with your
hands in the 9 o'clock and 3 o'clock posi­
tions to reduce the risk of injury if the airbag
deploys.
- Never hold the steer ing wheel in the 12
o'clock position or with both hands on the
rim or the center of the steer ing wheel.
Holding the steering wheel incorrectly s ig­
nificantly increases the risk of in jury to the
hands, arms and head if t he a irbag dep loys.

Driving
,.. Remove the ignition key in position @
9 page 76, fig. 85 9 ,&..
,.. Turn the steering wheel until you hear the
steering wheel lock.
The locked steering helps prevent vehicle theft.
A WARNING
- Never turn off the engine before the vehicle
has come to a complete stop. The full func­
tion of the brake booster and the power
steering is not guaranteed. You must use more force to turn or brake . Because you
cannot steer and brake as you usually
would, this co uld lead to accidents and seri-
. . . ous mJunes .
-Never remove the ignit ion key from the ign i­
t ion loc k while the vehicle is moving. Other­
wise, the steering lock could suddenly en­
gage and you would not be able to steer the
vehicle.
- If you leave the veh icle, switch the ignit ion
off and take the vehicle key with you. Other­
wise, the engine could be started or electri­
cal equipment such as the power windows
could be operated. This can lead to serious
injury.
- For safety reasons, always park the vehicle
with the selector lever in the P position.
Otherwise, there is the risk that the vehicle
could roll unintentionally .
(D Note
If the engine has been under heavy load for
an extended period of t ime, heat builds up in
the engine compartment after the engine is
switched off and there is a risk of damaging
the engine . For this reason, let the engine run
for at idle
for approximately two minutes be­
fore shutting it
off.
@ Tips
For up to 10 minutes after stopping the en­
gine, the radiator fan may turn on again auto­
matically or it may continue to run (even if
the ignition is sw itched
off) for the following
reasons:
76
- The coolant temperature is increasing due
to trapped heat.
- If the engine is warm and the engine com­
partment also heats up from strong sun­
light.
