Power Steering - Audi TTS Coupe 2015 Owner's Manual

Intelligent technology
Brake servo
The brake servo amplifies the pressure you apply
to the brake pedal. It only works when the engine
is running.
A
WARNING
- When applying the brakes to clean off de­
posits on the pads and discs, select a clear,
dry road. Be sure not to inconvenience or en­
danger other road users; do not risk an acci­
dent.
- Never let the car coast with the engine
switched off (this can cause accidents).
CD
CAUTION
- Never let the brakes "drag" by leaving your
foot on the pedal when you do not really in­
tend to brake. This overheats the brakes, re­
sulting in longer stopping distances and
greater wear.
- Before driving down a long, steep gradient,
it is advisable to reduce speed and select a
lower gear. In this way you will make use of
the engine braking effect and relieve the
load on the brakes. If you still have to use
the brakes, it is better to brake firmly at in­
tervals than to apply the brakes continuous­
ly.
{Q)
Note
- If the brake servo is out of action, you must
apply considerably more pressure to the
brake pedal than you normally would.
- If you wish to equip the car with accessories
such as a front spoiler or wheel covers, it is
important that the flow of air to the front
wheels is not obstructed, otherwise the
brakes can overheat.

General notes
On four-wheel drive vehicles, the engine power is
distributed to all four wheels. The distribution of
power is controlled automatically according to
your driving style and the road conditions. Also
refer to q page 107, Electronic stabilisation con­
trol (ESC).
The four-wheel drive is specially designed to
complement the superior engine power of your
Audi. This combination gives the car exceptional
handling and performance capabilities - both on
normal roads and in more difficult conditions,
such as snow and ice. Even so (or perhaps espe­
cially for this reason), it is important to observe
certain safety points q A. ..,.
