- If the b rake wa rning/in dicator light does
not go out after a few seconds and the pa rk­
ing brake is released, or lights up wh ile you
are driving, the fl uid level in the brake f lu id
rese rvoir is too low. If y ou believe t hat it is
safe to do so, proceed immediately at low

Braking
What affects braking efficiency?
New brake pads
During the first 250 miles (400 km), new brake
pads do not possess their full braking e ffect, they
have to be "broken in" first¢.&. . The break -in pe ­
riod can be considerably longe r for vehicles with
ceramic brake rotors*. You can compensate for
th is slightly reduced braking power by pushing
harder on the brake pedal. Avoid heavy braking
loads during the b reak-in period.
Op era ting condition s and dri ving h abit s
The brakes on today's automobiles are still sub­
j ect to wear, depending largely on operating con­
dit ions and driving habits ¢.&, . On vehicles that
are either dr iven most ly in stop-and-go city traf­
fic or are driven hard, the brake pads should be
checked by yo ur autho rized Aud i dealer more of­
ten than specified in the
Warranty & Mainte·
nan ce bookl et.
Fail ure to have you r brake pads
i nspected c an resu lt in red uced b rake pe rform ­
ance.
On steep slopes, you shou ld use the braking ef­
fect of the engine. This way, you prevent unnec ­
essary wear on the bra ke system. If yo u must use
you r brakes, do not hold the brakes down contin ­
u ously. Pump the brakes at intervals .
Operating noise
Noises may occur when brakin g depending on the
speed, braking force and ou ts ide cond itions su ch
as tempera ture and hum idity.
Due to the nature of the materials used in ceram­
i c bra ke roto rs*, noises may become mo re appa­
r ent at low speeds.
Effect of water and road salt
In certa in situations, for examp le after driv ing
through water, in heavy rain, after overnight con­
densation or after washing your car , the braking
effect can be redu ced by moistu re or ice on the
1111>

brake rotors and brake pads. The brakes must be
dried first with a few carefu l brake applications .
At h igher speeds and with the w indshield w ipers
turned on, the brake pads press against the brake rotors for a sho rt amount of time. This occurs at
regular intervals without the driver noticing and
prov ides for better brake response time under
wet conditions.
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered road
and the brakes are not used. Likew ise, you clean
off accumulated salt coating from brake discs
and pads with a few cautious applications of the
brake ¢,&. .
Due to their surface characteristics, ceram ic
brake rotors* absorb moisture in such conditions.
This can cause a temporary reduction in braking
force compared to dry brakes . You can compen ­
sate for this by press ing the brake pedal harder .
Corrosion
There may be a tendency for dirt to bui ld up on
the brake pads and corrosion to form on the discs
if the car is not driven regularly or only for short
trips with little use of the brakes .
If the brakes are not used frequently, or if corro­
sion has formed on the discs, it is advisable to
clean off the pads and discs by brak ing firmly a
few t imes from a moderately high speed¢& .
Fa ul ts i n the brake sys te m
If you should notice a sudden increase in brake
pedal travel, then one of the two brake circuits
may have failed¢&.
Low brak e flu id l eve l
Malfunctions can occur in the brake system if the
brake fluid level is too low. The brake fluid leve l is
monitored e lectronically.
Brake boo ste r
The brake booster increases the pressure that you
genera te with the brake pedal.

Brake lining wear statu s
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
thro ugh the openings in the wheel. If necessary,
the wheel may be removed for this inspection
¢ page 218, Replacing wheels .
A WARNING ...__
-New brake pads don't have the best stop­
ping power and must be "broken-in" during
the initial 250 miles (400 kilometers) . The
break-in per iod can be cons iderably longer
for vehi cles w ith ceramic b rake rotors*. You
can compensate for this by p ress ing the
b rake peda l more fi rmly. This a lso applies
later when new pads are installed.
- You shou ld perform braking maneuvers for
the purpose of cleaning the brake system
only if road conditions permit. Other road
users must not be put at risk -you may
cause an accident!
-
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gear or lower dr iving range. Do not ride the
brakes or hold the pedal down too long or
too often . This could cause the brakes to get
hot and dimin ish braking effic iency .
- Do not "ride the brakes" by rest ing your foot
on the pedal when you do not intend to
brake. This may cause the brakes to over­
heat, premature wear and increased stop­
p ing distance.
- Under certain cl imatic and operat ing condi­
tions such as passing t hrough water, dr iv ing
in heavy rain or after washing the veh icle,
the effect iveness of the brakes can be re­
duced . In winter, ice can accumulate on the
brake pads, linings, discs and drums . Care­
fu lly apply brakes for a test. Brakes will dry
and ice coatings will be cleaned off after a
few careful brake applications.
- Driving for an extended period of time on salt-covered roads without using your
brakes can a lso affect braking efficiency.
Clean off accumulated salt coating from brake discs and pads with a few careful
brake applications.

Breaking in
New engine
The engine needs to be run-in during the first
1,000 miles (1,500 km).
For the first 600 miles (1,000 kilometers ):
"' Do not use full throttle .
"' Do not drive at engine speeds that are more
than
2/3 of the max imum permitted RPM .
From 600 to 1,000 miles (1,000 to 1,500
kilometers):
"' Speeds can gradually be increased to the maxi­
mum perm issible road or engine speed.
During and after break-in period
"'Do not rev the engine up to high speeds when it
is cold. This applies whether the transmission is
in N (Neutral) or in gear .
After the break-in period
"'Do not exceed maximum engine speed under
any circumstances.
"'U pshift into the next higher gear
before reach­
ing the red area at the end of the tachometer
scale
c=> page 10.
During the first few hours of driving, the engine's
internal friction is higher than later when all the
moving parts have been broken in. How well this
break-in process is done depends to a considera­
ble extent on the way the vehicle is driven during
the first 1,000 miles (1,500 kilometers).
(D Note
Extremely high engine speeds are automati­
cally reduced. However, these rpm limits are
p rog rammed for an engine wel l run- in, not a
new engine.
@) For the sake of the environment
Do not dr ive with unnecessarily high eng ine
speeds -upshifting early saves fuel, reduces
noise and protects the environment.
Driving and the environment
New tires
If your vehicle is running on new tires, drive very
carefully for the fi rst 350 m iles (500 kilometers)
after fitting .
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. Avoid following closely behind
other vehicles or other situations that might
require sudden, hard brak ing .
Avoid damaging the
vehicle
When you are d riving on poor roads, or over
curbs, steep ramps, etc., ma ke certain that low­
lying parts such as spoilers and exhaust system
parts do not bottom out and get damaged.
T his is espec ially true for veh icles with low-s lung
chassis (sports chassis)* and fully loaded
vehicles.
Driving through water on
roads
Note the following to avoid vehicle damage when
driving through water, for example on f looded
roads:
- The water must not be any higher than the bot­
tom of the vehicle body.
- Do not drive faster than walking speed.
A WARNING
= -
After driving through water, mud, slush, etc.,
the brakes may be s low to take effect because
of wet brake rotors and pads. Dry the brakes
first by braking carefully to restore the full braking effect.
(D Note
Vehicle components such as the engine,
transmission, suspension or electrical system
can be severely damaged by driving through
water . ""

The radiator fan is driven by the engine via the V­
be lt. The viscous clutch regulates the speed of
the fan according to the temperature of the cool­
ant.
An auxiliary e lectr ic radiator fan * switches on and
off depending on coo lant temperature and other
veh icle operating conditions.
Afte r you switch the engine off, the a uxiliary fan
can cont inue running for up to 10 minutes -even
with the ignition off. It can even switch on again
l ater by itself
Q .&. , if
- the temperature of the engine coolant rises due
to the heat bui ld-up from the eng ine in the en­

- the engine compartment heats up because the
vehicle is parked in intense sunlight.
_& WARNING
- To reduce the r isk of personal injury never
touch the radiator fan.
- The aux iliary e lectr ic fan is temperature con­
trolled and can switch on suddenly even
when the engine is not running.
- The auxiliary radiator fan switches on auto­
matically when the engine coo lant reaches a
