Audi adaptive cruise control and braking guard
Audi braking guard
Description
Applies to veh icles: w ith Audi adaptive cruise co ntrol
Fig. 113 Instrument cluster : approach warn ing
Braking guard uses a radar sensor. It also func­
tions within the limits of the system when adap­
tive cruise control is switched off.
What can Audi braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes suddenly
or if your own vehicle is traveling at a high speed
and approaching a vehicle up ahead that is mov­
ing more slowly . Braking guard does not react if it
cannot detect the situation .
The system advises you of various situations:
- The
distance warning is given if you are too
close to the vehicle ahead for a long time. If the
vehicle ahead brakes sharply, you will not be
able to avoid a collision. The indicator light.
in the display comes on .
- The
approach warning is given when a detected
vehicle up ahead in your lane is moving much
more slowly than you are or if it brakes sharply .
When this warning is given, it may only be pos­
s ib le to avoid a collision by swerving or braking
sharply. The indicator light . and indicato r in
the display will wa rn you about the danger
¢ fig. 113 . You will also hear an acoustic signa l.
If you do not react fast enough or do not react at
all to the situation, Braking guard will intervene
by braking and the message
braking guard inter­
vention
will appear.
ll Thi s is not available in so me c oun tries.
96
- If a co llision is imminent, the system wi ll first
provide an
acute warning by br iefly and sharply
app ly in g the brakes.
- If you do not react to the acute warning, brak­
ing guard can brake within the limits of the sys­
tem. This reduces the vehicle speed in the event
of a collision.
- At speeds under 20 mph (30 km/h), the system
can initiate a complete deceleration shortly be­
fore a collisionl l_
-If the braking guard senses that you are not
braking hard enough when a collision is immi­
nent, it can increase the braking force.
Which functions can be controlled?
You can switch braking guard and the distance/
approach warning on or off in the radio or MMI
¢page
97, Settings in the radio/MM!.
A WARNING
Lack of attent ion can cause collisions, other
accidents and ser ious personal injuries. The
braking guard is an assist system and cannot
prevent a coll is ion by itself. The dr iver must
always intervene. The driver is always respon­
sib le for braking at the correct time.
- Always pay close attent ion to traffic, even
when the braking guard is switched on. Be
ready to intervene and be ready to take com­
plete control whenever necessary. Always
keep the safe and legal distance between
your vehicle and vehicles up ahead.
- Braking guard works within limits and will
not respond outside the system limits, for
examp le when approaching a stopped vehi­
cle or stationary obstacle (end of a traffic
jam or vehicle that has broken down in traf­
fic).
- Always remember that the radar sensor for
the braking guard works only w ith in defined
detection and range limits that may prevent
the proper detection of other vehicles.
- The radar sensor's function and range can
be reduced by rain, snow and heavy spray.

Braking
What affects broking efficiency?
New brake pads
During the first 250 miles (400 km), new brake
pads do not possess their full braking effect, they
have to be "broken in" first¢,&. . You can com­
pensate for this slightly reduced braking power
by pushing harder on the brake pedal. Avoid
heavy braking loads during the break-in period.
Operating conditions and driving habits
The brakes on today's automobiles are still sub­
ject to wear, depending largely on operating con­
ditions and driving habits~,&. . On vehicles that
are either driven most ly in stop-and -go city traf­
fic or are driven hard, the brake pads should be
checked by your authorized Audi dealer more of­
ten than specified in the
Warranty & Mainte­
nance booklet .
Failure to have your brake pads
i nspected can result in reduced brake perform­
ance .
On steep slopes, you should use the braking ef­
fect of the engine . This way, you prevent unnec­
essary wear on the brake system. If you must use
your brakes, do not hold the brakes down contin­
uously. Pump the brakes at intervals.

Operating noise
Noises may occur when braking depending on the
speed, braking force and outside conditions such
as temperature and humidity.
Effect of water and road salt
In certain situat ions, for example after driving
through water, in heavy ra in, after overn ight con­
densat ion or after washing your car, the braking
effect can be reduced by moisture or ice on the
brake rotors and brake pads. The brakes must be
dried first with a few carefu l brake applications.
At higher speeds and with the w indshie ld w ipers
turned on, the brake pads press against the brake
rotors for a short amount of time. This occurs at
regular intervals without the driver noticing and
provides 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. Likewise, you clean
off accumulated salt coating from brake discs
and pads with a few cautious applications of the
brake ¢.& .
Corrosion
There may be a tendency for dirt to build up on
the brake pads and corros ion to form on the discs
if the car is not driven regularly or only for short
tr ips with little use of the brakes.
If the brakes are not used frequently, or if corro­
sion has formed on the discs, it is advisab le to
clean off the pads and discs by braking firmly a
few t imes from a moderately high speed¢.&.
Faults in the brake system
If you should notice a sudden increase in brake
pedal trave l, then one of the two brake circuits
may have failed
c:> .& .
Low brake fluid level
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 lining wear status
Brake lining wear may be checked by visual in­
spect ion of the condition of the brake pads
through the openings in the wheel. If necessary,
the wheel may be removed for this inspection
c:> page 230, Replacing wheels.
_8 WARNING "'---
-New brake pads don't have the best stop­
pin g power and must be "broken-in" during
the initial 250 miles (400 kilometers). You
can compensate for this by press ing the
brake pedal more firmly. This also 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 r isk -you may
cause an acciden t!
- Before descending a steep grade, reduce
speed and shift transmission 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 over­
heat, premature wear and increased stop­
p in g distance.
- Under certain cl imatic and operat ing condi­
tions such as passing through water, dr iv ing
in heavy rain or after washing the vehicle,
the effectiveness of the brakes can be re­
duced. In winter, ice can accumulate on the
b rak e pads, linings, discs and drums. Care­
fully 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 wi thout using your
brakes can a lso affect braking efficiency .
173

Smart Technolog y
Clean off accumulated salt coating from
brake discs and pads w ith a few carefu l
brake applications .
- If you damage the front spoiler, or if you in­
stall a d ifferent spoiler, be sure the air flow
to the front brakes is not obstructed. Other­
wise the brake system could overheat reduc ­
ing the effectiveness of the entire brake sys­
tem.
- Failure of one brake c ircuit will impair the
braking capab ility result ing in an increased
stopp ing distance. Avoid driving the veh icle
and have it towed to the nearest autho rized
Audi dealer or qualified workshop.
- Never let the vehicle ro ll to a stop with the
engine shut off .
- If the brake booster is not work ing, the
brake pedal must be pressed considerably
harder to make up for the lack of booste r as­
sistance .

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 . ""

Economical and environ­
mentally-friendly driving
General
Your personal style of driving will determine the
economy of your vehicle, as well as exhaust and
noise levels.
Fu el economy, environmental impact , and wear
on your engine, brakes and tires largely depend
on three factors:
- your persona l dr iving style
- operating conditions
- technical limitations
If you anticipate what you need to do next and
drive economically, you can easily cut your fuel
consumption by 10-15 percen t. This sec tion will
give you some tips on how you can help the envi ­
ronment and your pocketbook .
(!) Tips
The consumpt ion estimates as published by
ENVIRONMENTAL PROTECTION AGENCY (EPA)
and Transport Canada may not correspond to
your actual consumption on the road, which
w ill vary depending upon vehicle load and
speed, road and weather conditions, trip
length, etc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating.
" Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are acceler ­
ating . If you anticipate what is going to happen
next, you will need to brake less and, thus, accel­
e rate less. Let the vehicle coast whenever possi­
ble - for example when yo u see that the next traf­
fic light is red .
Driving and the environment
Avoid full throttle
Driving at moderate speeds saves fuel and im­
proves your mileage .
"Try and keep well below your car's maximum
speed.
Acce lerat ing gently reduces fue l consumption,
engine wear, and does not disturb the environ­
ment .
Fuel consumption, exhaust emissions and engine
noise increase disproportionately at high speeds.
If you drive at approximate ly three quarters of
top speed, fuel consump tion will be reduced by
one half. Never drive faster than the posted
speed l imit and weather cond itions permit .
Reducing unnecessary idling
Even when your car is jus t idling it burns up fuel.
" Shut the eng ine off when you are not driving
the vehicle.
" Do not warm up the vehicle by lett ing the en-
gine run at idle.
It makes sense to shut off the engine in traffic
jams, when wa iting for tra ins to pass a t railroad
crossings, or at traffic lights that have long waits
on red . Turning the engine
off for just 30-40 sec ­
onds saves more fue l than is burned starting the
. . engine again.
It takes a long t ime for the engine to warm up
fully when it is running at idle. However, wear
and noxious emissions are especially high when
the engine is warming up. So you should drive
away as soon as you sta rt the engine and avoid
running at high rpms wh ile the engine is st ill
warming up.
(D Note
Do not leave engine idling unatt ended afte r
starting .
If warning lights should come on to
indicate improper operation, they would go
un heeded . Extended idling also produces
heat, which could result in overheating or oth­
er damage to the vehicle or other property.

Trailer mode Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation.
If you plan to tow a tra iler, p lease remember that
the additiona l load will affect durability, econo­
my and performance .
T railer towing not on ly places more stress on the
vehicle, it also calls for more concentrat ion from
the driver .
F or this reason, a lways fo llow the operating and
d riving instructions provided and use common
sense.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suitable
for your vehicle and trailer and must be mounted
securely on the veh icle 's chassis at a technically
sound
location . Use on ly a tra iler hitc h with a re­
movable ba ll mou nt. Always chec k w ith the t ra il­
e r hitch m anu fac tur er to make sure that you a re
using the co rrec t hitch.
Do not use a bumper hitch .
The hitch must be installed in such a way that it
does not in terfere with the impact-absorbi ng
bumper system. No mod ificat ions should b e
mad e to the vehicle exhaust and brake systems .
Fr om time to t ime, c hec k t hat a ll h itch mou nti ng
bo lts remain sec urely fastened .
When you are no t tow ing a trailer,
remove the
trai ler hitch ball mount . Th is prevents the hitc h
fr om caus ing damage should you r vehicle be
s truck from behind¢,&. .
Trailer brakes
If yo ur tra iler is equipped w it h a braking system,
check to be s ure that it conforms to all regu la­
tions.
Trailer mode
T he trailer hyd raulic brake system must not be di ­
rect ly connected to the ve hicle's hydraulic b rake
system ¢.&. .
Safety chains
Alw ays use s afety ch ains be tween your ve hicle
and t he tra ile r.
Trailer lights
Tra ile r li ghts must meet all regulations. Be sure
to check w it h your author ized Audi deal er for cor­
r e ct w iring, sw itches, and relays.
Mirrors
If you are unable to see the traffic behind you us­
i ng the regular o uts ide mirrors, then you
must in ­
sta ll extended mirrors .
It is importa nt that you
always have clea r vision to the rea r.
_&. WARNING
- I f a trai ler has elec trical brake s please note
th at these b ra kes are not acti va ted by the

- After removing the t railer hi tch, do n ot store
it in your vehicle . In case o f su dden braking,
the hi tch could fly forward and injure you or
your passe ngers.
Operating instructions
Maximum traile r weight
A trai ler for you r vehicle is limited to a typical
class 1 or class 2 trailer.
Trailer load distribution
B e sure the load in the t ra iler i s held secure ly in
pla ce to prevent it from sh ifting forw ard , back ­
war d or sideways .
Never allow a passenger to ride in a trailer¢.&.
in Driving in struc tion s on page 182.
Engine cooling system
Towing a trailer makes the engine work harder . It
is important that the cooling system's pe rform­
ance is up to the additional load . Ma ke s ure that
t h e coo ling system has enoug h fluid.

Trailer mode
Tire pressure
When tow ing a trailer, inflate the tires of your ve­
hicle to the cold tire pressure listed under " Full
load" on the label located on the driver's side B ­
pillar (visible when the door is open). Inflate
trailer tires to trailer and tire manufacturers'
specifications.
Lights
The headlight settings should be checked with
the trailer attached before driving off . Check to
make sure both vehicle and trailer lights are
working properly.
Safety chains
Be su re trailer safety chains are properly connect­
ed from the trailer to the hitch on the vehicle.
Leave enough slack in the chains to permit turn­
ing corners. When you install safety chains, make
sure they will not drag on the road when you are
driving.
The chains shou ld cross under the trai ler tongue
to prevent it from dropping in case of separation
from the hitch.
Driving instructions
Driving with a trailer always requires extra care
and consideration.
To obtain the best possible handling of vehicle
and trai ler, please note the following:
.. Do not tow a loaded trailer when your car itself
is not loaded .
.. Be especia lly careful when passing other
vehicles.
.. Observe speed limits.
.. Do not drive at the maximum permissible
speed .
.. Always apply brakes early.
.. Monitor the temperature gauge.
Weight distribution
Towing a loaded trai ler with an empty car results
in a highly unstable distribution of weight. If this
cannot be avoided, drive at very low speeds only
to avoid the risk of losing steering control.
182
A "balanced" rig is easier to operate and contro l.
This means that the tow vehicle shou ld be loaded
to the extent possible and permissib le, wh ile
keep ing the trailer as light as possible under the
c ir cumstances. Whenever poss ible, transfer
some cargo to the luggage compartment of the
tow veh icle while observing tongue load require­
ments and vehicle load ing considerat ions .
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the rig. Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or w ind
cond it ions are unfavorab le - particularly when
go ing downh ill.
Reduce veh icle speed
immediately if the trailer
shows the slightest sign of swaying.
Do not try
to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds for
vehicles towing tra ilers are lower than for regular
vehicles.
Always apply brakes early. When dr iving down­
hill, shift into a lower gear to use the engine
braking effect to slow the vehicle. Use of the
brakes alone can cause them to overheat and fail.
Coolant temperature
The coolant temperature gauge¢ page 10 must
be observed carefully. If the needle moves close
to the upper end of the scale, reduce speed im­
med iately and/or turn off the air conditioner .
If the coolant temperature warning light . in
the instrument cluster starts flashing, pull off
the road, stop and let the engine
idle for about
two m inutes to prevent heat build-up .
&_ WARNING
Anyone not properly restrained in a moving
vehicle is at a much greater risk in an acci­
dent. Never let anyone ride in your car who is
not properly wearing the restraints provided
by Audi.

Trailer mode notes
Important to know
Your vehicle hand les differently when tow ing a
trailer because of the additional weight and dif­
ferent weight distribution. Safety, performance
and economy will greatly depend on how careful­
ly you load your trailer and operate your rig.
Before you actually tow your trailer, practice
turning, stopping and backing up in an area away
from traffic. Keep practicing until you have be­
come completely familiar with the way your vehi­
cle-trailer combination behaves and responds.
Backing up is difficult and requires practice. Back­
ing up with a trailer generally requires steering
action opposite to that when backing up your ve­
hicle without a trailer .
Maintain a greater distance between your vehicle
and the one in front of you. You wi ll need more
room to stop. To compensate for the trailer, you
will need a larger than normal turning radius.
When passing, remember that you cannot acce l­
erate as fast as you normally would because of
the added load. Make sure you have enough room
to pass. After passing, allow plenty of room for
your trailer before changing lanes again.
Avoid jerky starts, sharp turns or rapid lane
changes.
(D Tips
