ment Safety first Vehicle operation
& WARNING
•
You should perform braking maneuvers for the purpose of
cleaning the brake system only if road condition s permit. Other
road users must not be put at risk -you may cause an accident!
• Before descending a steep grade, reduce speed and shift trans ­
mission into a lower gear or lower driving 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 diminish braking efficiency.
• Do not "ride the brakes " by resting your foot on the pedal when
you do not intend to brake. This may cause the brakes to overheat,
premature wear and increased stopping di stan ce.
• Under certain climatic and operating conditions such as
passing through water, driving in heavy rain or after washing the
vehicle, the effectiveness of the brakes can be reduced. In winter,
ice can accumulate on the brake pads , linings, discs and drums .
Carefully 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 also affect braking efficiency. Clean
off accumulated salt coating from brake discs and pads with a few
careful brake applications.
• If you damage the front spoiler, or if you install a different
spoiler, be sure the air flow to the front brakes is not obstructed.
Otherwise the brake system could overheat reducing the effective­
ness of the entire brake system .
• Failure of one brake circuit will impair the braking capability
resulting in an increased stopping di stance . Avoid driving the
vehicle and have it towed to the nearest Audi dealer or qualified
workshop .•
