sages ing! Restricted stability
A WARNING
Only switch sport mode on when your driving
abilities and the traffic s ituation permit, be-
cause there is a risk of slid ing .
- The stabilization function is limited when
sport mode is sw itched on. The driving
wheels could spin and the vehicle cou ld
swerve, espec ially on slick or slippery road
surfaces .
(D Tips
Sport mode cannot be sw itched on if the
cru ise control system* or adaptive cruise con-
trol* is switched on.
Braking
What affects braking efficiency?
New brake pads
During the first 250 miles (400 km), new brake
pads do not possess the ir full braking effect, they
have to be "broken in" first ¢ .&.. You can com-
pensate for this slightly reduced braking power
by push ing harder on the brake pedal. Avoid
heavy braking loads during the break-in pe riod .
Operating conditions and driving habits
The brakes on today's automobiles are still sub-
ject to wear , depend ing largely on operating con-
d itions and dr iving hab its ¢ .&.. On veh icles that
are eith er dr iven most ly in stop-and-go city traf-
fic or are driven hard , the brake pads should be
checked by your authorized Aud i deale r more of-
ten than spec ified in the
Warranty & Mainte-
nance booklet.
Failure to have your brake pads
inspected can result in red uced brake perform-
ance.
On steep slopes, you should use the brak ing ef-
fect of the engine. This way, you prevent un nec-
essa ry wea r on the brake system. If you must use
you r brakes, do not ho ld the brakes down contin-
uous ly. Pump the brakes at intervals.
Operating noise
Noises may occur when braking depending on the
speed, bra king fo rce and outside conditions such
as temperature and humidity.
Effect of water and road salt
In certain situations, for example after driving
through water, in heavy rain, after overn ight con-
densation or afte r wash ing your car, the brak ing
effect can be reduced by moisture o r ice on the
brake rotors and brake pads. The brakes must be
dried first with a few careful brake applications .
At h igher speeds and w ith the windshield wipers
turned on, the brake pads press against the brak e
rotors fo r a short amount of time. This occurs at
regular intervals without the driver noticing and
provides for better brake response t ime under
wet conditions.
The effectiveness of the brakes can be reduced
when the vehicle is driven on a sa lt-c overed road
and the brakes are not used . Likewise, you clean
off accum ulated salt coating from brake discs
and pads with a few cautious applications of the
brake¢ .&..
Corrosion
There may be a tendency fo r dirt to build up on
the brake pads and corrosion to form on the discs .,..
