(D Tips
Applies to: ve hicles w ith d iese l engines
Due to the high eff ic iency of these engines,
the engine may not always reac h opera ting
t em perature i n cold outside tempe ra tur es.
This is normal and not a cause for con cern .
Tachometer
The tachometer displays the engine speed in rev ­
olutions per minute (RPM).
You shou ld shift to the next lowest gea r whe n
the speed is below 1,S00 R PM. T he begin ning of
the re d zone in the tachome ter ind icates the
maximum permissible engine speed fo r all gea rs
once the engine has been bro ken in and when it is
warmed up to operating temperature . Before
reaching the red zone, you should shift into the
next h igher gea r, c hoose the Dor S selecto r lever
position, or remove your foot from the accelera­
tor pedal.
CD Note
The needle in the tachometer @ c> page 9,

General information
Breaking in
A new vehicle must be broken in, and the break­
in distance should be 1,000 mi les ( 1,500 km). Do
not drive at speeds that w ill exceed
2/3 of the
maximum permitted engine speed
(RPM) for the
first 600 miles (1,000 km) , and avoid full accel­
eration 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 during the first 1,000
miles (1,500 km) also affects the engine quality.
Drive at moderate engine speeds after the initial
break-in per iod, part icularly when running a cold
engine . This will reduce engine wear and improve
the mileage .
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 .
New tires
If your vehicle is running on new tires, drive pa r­
ticularly careful for the first 350 miles (500 kilo­
meters) after fitting .
.&_ WARNING
-
New tires tend to be slippery and must also
be "broken-in". Be sure to remember this dur­
ing the first 350 miles (500 kilometers).
Brake gently . Avo id following closely behind
other vehicles or other situations that might
require sudden, hard brak ing.
Avoid damaging the vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that low-
D riving
lying parts such as spoilers and exhaust system
parts do not bottom out and get damaged .
T h is is espec ially true for veh icles with low-slung
chass is (sports chassis)* and fully loaded
vehicles.
Warming up/cooling down
Appl ies to: Sand RS models
By warming up/cooling down the engine careful­
ly, you can he lp reduce unnecessary strain on
your vehicle when driving in a sporty style.
The engine speed is limited when the engine is
cold -the full engine output is not available.
When the engine is at operat ing temperature,
the engine speed limitation moves to a higher
RPM range. The tires also only reach their full
road holding capab ility once they have warmed
up .
Your vehicle also has an after-run cooling fea­
ture . However, cooling down is still important.
The engine and the brakes as well as the exhaust
system and the transmission become very hot
when driving in a spo rty style . Before you shut
the vehicle off, you should cool down the vehicle
by driving a few miles at low speeds with light ac­
celeration.
Driving through water on roads
Note the following to reduce the risk of vehicle
damage when driving through water, for example
on flooded roads:
- The water must not be any higher than the bot­
tom of the vehicle body .
- Do not drive faste r than walking speed.
.&_ WARNING
= -
After driving through water or mud, the effec-
tiveness of the brakes may be reduced due to
moisture on the brake rotors and brake pads.
A few careful brake applications should dry
off the brakes .

Lap timer
Introduction
Applies to: vehicles with lap timer
You can record and evaluate lap times with the
lap timer ¢ page
87, fig. 88. Th e time is meas­
ur ed in m inutes, seconds and 1/10 seconds . The
hours are also shown when the lap time exceeds
60 minutes. The maximum individual measure ­
ment is 99 hours. A maximum of SO laps can be
recorded.
A WARNING
-Your focus shou ld always be on driving your
vehicle safe ly. As the driver, you have com­
plete respons ibility for safety in traffic. Only
use the functions in such a way that you al­
ways maintain complete control over your ve­
hicle in all traffic situations .
@ Tips
You can retr ieve informat ion from the tr ip
computer wh ile the lap timer stopwatch is
r unning.

\.J ' intervals and ensures a better reaction time fo r
the brakes in wet weather.
The braki ng effect can also be red uced if you are
driving on salted roads and you do not apply the b rakes for long periods of time . The layer of salt
on the brake rotors and pads must be worn off
f irst when the brakes are app lied.
Due to its surface, the ceramic bra ke rotor* ab­
sorbs moisture in certa in situations. There fore,
there will temporarily be less braking force than
when the brakes are dry . You can compensate for
this by pressing the brake pedal harder.
Cor rosion
L eaving the vehicle parked fo r long periods of
time, low mi leage and avoiding heavy braking
can contribute to corrosion on the brake rotors
and to dirty brake pads.
I f you usually avo id heavy braking or if there is
corrosion present , occasional heavy braking at
high speeds is recommended to clean the brake
rotors and pads
q ,& .
Brak e system malfunct ion
if you notice that the brake pedal travel has sud­
denly increased, then a brake c ircui t in the dual­
circuit brake system may have malfunctioned. Drive to an authorized Audi dea ler or a uthorized
Aud i Service Facility immediately to have the
problem corrected. On the way there, drive with
reduced speed and keep in mind that you w ill
need a longer distance to stop and you w ill need
to p ress the b rake pedal harde r.
L ow brake fluid level
When the brake fl uid level is low, malfunct ions in
the brake system may occur . The brake f lu id level
is electronically monitored.
Br ak e boost er
The brake booster amplifies the pressure you ap­
p ly to the brake peda l. It only works when the en­

- Only apply the brakes for the purpose of
cleaning the brake system whe n road and

traffic conditions permit. You must not en­
danger other road users. This increases the
risk of an accident.
- Never let the vehicle roll while the engine is
stopped because this increases the risk of an
accident.
- New brake pads do not ach ieve the ir full
braking effect during the first 250 m i
(400 km). They m ust be "broken in" first.
The break-in per iod ca n be cons iderably lon­
ge r fo r vehicles with ceram ic brake rotors* .
H owever, you can compensate fo r the
slightly reduced braking force by pressi ng
fi rm ly on the brake pedal. Avo id heavy b rak­
ing du ring the break -in pe riod.
- Ce rtain weathe r and ope rating condi tions
such as driving through water, dr iv ing in
heavy rain o r driv ing after was hing your ve­
hicle can impa ir the effect iveness of the
brakes. In the winter, ice may build up on
the brake pads, rotors and drums . Check
these components by braking carefully. Ap­
p lyi ng the brakes carefully several times
d ries the b rakes and removes ice build-up .
- The efficiency of the brakes can also be im­
pa ired by dr iv ing for long stretches on roads
covered with sa lt without using the bra kes .
You can remove salt deposits from the
b rake rotors and pads by carefully applying
t he brakes several times .
- I f the fron t spoiler is damaged o r yo u install
another spoi ler, make su re the front wheel
b rakes are ven tilated properly . Othe rw ise,
the brake system co uld overheat, which re­
duces their effectiveness .
- Fa ilure of a brake circuit impairs brak ing
pe rformance, which increases b raking dis­
tance. Avo id driving the vehicle and have it
towed it to the nearest a uthorized Audi
deale r or authorized Aud i Serv ice Facility.
- I f the brake booster is not working, yo u w ill
have to p ress much harder on the brake
pedal to compensate fo r the lack of the
booster.
Q) Note
- Never let the brakes "rub" by pressing the
peda l lightly when braking is not actually

necessary. This causes the brakes to over ­
heat and increases bra king distance and
causes wear .
- Befo re driving downhi ll a long distance on a
steep hill, decrease your speed and select a
l ower gear. This makes use of the engine
braking effect and relieves the brakes. If
you need to brake additionally, b rake in in­
t e rvals a nd not continuously .
(D Tips
-If the brake booster is not working, you
must press the brake pedal with much more
force than normal.
- If you retrofit you r vehicle with a front spoil­
e r, whee l covers o r similar items , make sure
that the a ir flow to t he fron t wheels is not
i nte rr u pted . Othe rw ise the brake sys tem
ca n become too hot .
