Audi adaptive cruise control and braking guard
When the adaptive cruise control is turned on,
you must press the clutch to shift gears (as usu­
al) . When shifting normally or when press ing the
clutch, the adaptive cruise control remains
turned on.
After you have engaged the gear, you do
not
need to press the gas pedal. The adaptive cruise
control accelerates automatically if necessary.
If you press down on the clutch for too long or
shift/coup le improperly , the adaptive cruise con­
trol may turn off automatica lly.
@ Tips
You cannot turn on the adaptive cruise con­
trol during a shifting operation .

Description
Applies to vehicles: with Audi adaptive cruise control
Fig . 115 De tect ion range
What can Audi adaptive cruise control do?
The adaptive cruise control works in conjunction
with a radar sensor installed in the front of the
veh icle
,::;,page 98, fig. 112, wh ich is subject to
designated system limits
r::;, page 100. Stationary
objects are disregarded.
On open roads with no traffic, adaptive cru ise
control works like a reg ular cruise control sys­
tem. The stored speed is ma inta ined. When ap­
proaching a moving vehicle detected up ahead,
the adaptive cruise cont rol system automatically
slows down to match that vehicle's speed and
then maintains the distance that the driver previ­ ously stored. As soon as the system does not de-
100
tect a ve hicle up ahead, adaptive cruise control
acce lerates back up to the stored speed.
Which functions can be controlled?
When you switch adapt ive cru ise control on, you
can set the current speed as the "control speed"
9 page 100, Switching on and off.
When dr iving, you can stop cruise control
9 page 102 or change the speed r::;, page 101 at
any time .
You can also set the distance to the object ahead
and set the adaptive cruise control driving pro­
gram

by the system by braking yourse lf, by accel ­
erating noticeably or by swerving.

-To avoid being burned, do not spill anti­
freeze or coolant on the exhaust system or hot engine parts. Under certain condi­
tions, the ethylene glycol in engine cool­ ant can catch fire.
- Antifreeze is poisonous. Always store anti­
freeze in its original container and well out
of the reach of children.
- If you drain the coolant, it must be caught
and safely stored in a proper container
clearly marked "poison".
(D Note
-Do not add coolant if the expansion tank is
empty . Air could enter the cooling system
and damage the engine. If this is the case,
do not continue driving. Seek professional
assistance.
- Coolant pollutes the environment and could
cause an engine fire. Excess coolant will be
forced out through the pressure relief valve
in the cap when the engine becomes hot.
- If, in an emergency, only water can be add­
ed, the correct ratio between water and an­
tifreeze
c::> page 208 must be restored as
soon as possible.
@) For the sake of the environment
Drained coolant should not be reused. Always
dispose of used coolant while observing all
environmental regulations.
Radiator fan
The radiator fan switches on automatically by it­
self.
The radiator fan is driven by the engine via the V­
belt . The viscous clutch regulates the speed of
the fan according to the temperature of the cool­
ant.
An auxiliary electric radiator fan* switches on and
off depending on coolant temperature and other
vehicle operating conditions.
After you switch the engine off, the auxiliary fan
can continue running for up to 10 minutes -even
Checking and Filling
with the ignition off. It can even switch on again
later by itself
c::> & , if
- the temperature of the engine coolant rises due
to the heat build-up from the engine in the en­
gine compartment, or
- the engine compartment heats up because the
vehicle is parked in intense sunlight.
A WARNING
-To reduce the risk of personal injury never
touch the radiator fan.
- The auxiliary electric fan is temperature
controlled and can switch on suddenly even
when the engine is not running.
- The auxiliary radiator fan switches on auto­
matically when the engine coolant reaches a
certain temperature and will continue to run
until the coolant temperature drops.
Brake fluid
Checking brake fluid level
The broke fluid level con be checked with o quick
glance .
