Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 123 Instr ument cluster: approach warning
Braking guard uses a radar sensor. It also
functions within the limits of the system
when adapt ive 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 sud­
denly or if your own vehicle is traveling at a
high speed and approaching a vehicle up
ahead that is moving more slowly. Braking
guard does not react if it cannot detect the
s ituation.
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 de­
tected vehicle up ahead in your lane is mov­
ing much more slowly than you are or if it
brakes sharply. When thi s war ning is given,
it may on ly be possible to avoid a co llision
by swerving or brak ing sharp ly. The indicator
light . and indicator in the display will
warn you about the danger

wi ll also hear an acoustic signal.
If you do not react fast enough or do not react
at all to the situation, Braking guard will in­

Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of veh icle control. It works
only when the eng ine is running. ESC detects
certain difficult driv ing situations, including
when the vehicle is beginning to spin (yaw) out of cont ro l and he lps you to get the vehicle
back under control by select ively b rak ing the
wheels, and/or red ucing engine powe r and
p roviding steering assistance to help hold the
ve hicle on the driver's intended course . The in­
dicator light
DJ in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem­
ber that ESC cannot overcome the laws of
phys ics. It will not a lways be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
h elp you master situat ions where there is a
sudden change in the coefficient of fr iction of
the road surface. When there is a sect io n of
d ry road that is s udden ly cove red with water,
slush o r snow, ESC canno t perform the same
way it would on the dry su rface.
If the vehicle
hydroplanes (rides on a c ush ion of wate r in­
stead of the road surface), ESC wi ll not be
ab le to he lp you steer the veh icle because con-
Int ellig ent technolog y 185
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
D uring fast corner ing, particular ly on wind ing
roads, ESC cannot always deal as effectively
with difficult dr iv ing s ituations than at lower
speeds. When towing a trailer, ESC is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffic and weather conditions . ESC can­
not override the vehicle's physical lim its, in­
crease the availab le tract ion, or keep a veh icle
o n the road if road departu re is a result of
driver ina ttent io n. Instead , ESC imp roves the
poss ibility of keep ing t he vehicle under con­
trol and on the road during extreme maneu­
vers by using the driver's steering i nputs to
help keep the vehicle go ing in the intended di­
rect ion. If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
ESC is switched on all the time. In certain sit­
uat ions when you need less traction, you can
switch off ASR by pressing the butto n
[ill
~ page 187, fig. 174 or~ page 187,
fig. 175. Be sure to sw itch ASR on aga in when
you no lo nger need less traction.
The following systems are integrated in the
ESC:
Anti-lock bra king sy stem (ABS )
ABS prevents the whee ls from locking up
when brak ing. T he vehicle can st ill be steered
even dur ing hard braking. App ly steady pres­
su re to the brake peda l. Do not pump the ped­
al. A pulsing in the brake pedal ind icates that
the system is helping you to brake the veh icle .
Brake assi st system
The brake ass ist system can decrease braking
distance. It increases brak ing power when the
drive r presses the brake peda l quickly in emer­
gency s ituations. You must press and hold the
brake pedal unti l the s ituation is over. In
vehicles wi th adap tive c rui se control*, the
brake assis t system is more sensitive if the
•
•

186 Intelligent technology
distance detected to the vehicle ahead is too
smal l.
Anti-slip regulation (ASR )
ASR reduces eng ine power when the drive
wheels begin to spin and adapts the fo rce to
the road condit ions. This makes it eas ier to
start, accelerate and drive up hills .
Electronic differential lock (EDL)
The EDL brakes wheels that are spinn ing and
transfers the d rive powe r to the other drive
wheel or whee ls if the vehicle is equipped with
a ll-wheel drive* . This function is not avai lab le
at higher speeds.
I n extreme cases , EDL automat ica lly switches
off to help keep the brake on the braked whee l
from ove rheating . EDL wi ll switch on again au­
tomatically when conditions have returned to
normal.
Steering recommendation
The ESC helps to stabilize the ve hicle by
changing the steering torque.
In vehicles with dynam ic steeri ng*, ESC also
he lps to stabilize the stee ring in critical s itua­
tions.
Electronic interaxle differential lock* /
selective wheel torque control*
The electronic interaxle d ifferential lock (front
wheel drive) or the select ive wheel torque
con trol ( all wheel d rive) oper ates when driving
through curves . The front whee l on the inside
of the cu rve or both whee ls on the inside of
the curve are b raked se lectively as needed.
This a llows more prec ise driving in c urves. The
applicable system may not activate when driv­ ing i n wet or snowy conditions.
A WARNING
- The ESC and its integrated systems can­
not overcome the laws of physics. This is
especially important on slippery o r wet
roads . If the systems begin acting to sta·
b iliz e your veh icle, you s hou ld immed i­
a tely c ha n ge your speed to match the
road and traffic cond itions. Do not let
the increased safety provided by these
systems tempt you to take risks. Do ing
so will increase the risk of a loss of vehi­
cle control, collision and serious personal
inj uries.
-Always adapt your speed to road, traffic and weather conditions. The risk of los­
ing control of the vehicle increases when
d riving too fast, espec ially through
curves and on slippe ry or wet roads, and
when dr iv ing too close to vehicles up
ahead. The ESC a nd its integrated sys­
tems canno t always p reven t collisions -
there is still a risk of acc idents!
- Always accelera te wi th spe cial care on
even, smooth s urfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even with these assistance systems that cannot al­
ways he lp to red uce the risk of loss of ve­
h icle control.
(D Tips
- ABS and ASR only work cor rectly when
all four wheels are equipped with identi­
cal tires. D ifferent tire sizes can lead to a
reduction in engine power .
- Yo u may hear noises when the systems
descr ibed are working.
- If the ind icator light

Operating conditions and driving habits
T he brakes o n today 's automobiles a re still
s u bject to wear, depe nding largely on ope rat­
i ng condi tions and driving habi ts¢ ,&. On
vehicles that are ei ther dr iven most ly in stop­
and -go city traffic or are dr iven hard, the
brake pads should be checked by your author­
ized Audi dea ler mo re often than specified in
the
Warranty & Maintenance booklet . Failure
to have your brake pads inspected can result in reduced brake performance .
On steep slopes, you sho uld use the braking
effect of the engine . This way, you prevent un ­
necessary wear on the brake system . If you
must use your brakes, do not hold the brakes
down cont inuous ly. Pump the brakes at inter­
vals.
Operating noi se
Noises may occur when braking depending on
the speed, brak ing force and outside cond i­
t ions such as temperature and humidity.
Effect of water and road salt
In certain situations, for examp le afte r driving
t hr ough water, in heavy rain, after overnight
condensation or after wash ing your car, the
braking effect can be reduced by moisture o r
ice on the brake rotors and brake pads. The
brakes must be dr ied first wi th a few ca reful

Maintenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impair
the function of the emission control
system and could lead to damage.
@ For the sake of the environment
Even when the Emission Control System is
operating properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operating states. This depends on
the sulfur content of the fuel being used .
Using a different brand of fuel may help,
or filling the tank with lead-free super
grade gaso line.
Shutting down vehicle
If you wou ld like your veh icle to remain inop­
erat ive for a longer period of time, contact an
Aud i or other specialized dealer. They can ad­
vise you on necessary precautions e .g. corro­
sion prevention, maintenance and storage. Pay attention to add itional information con­
cerning the battery. Refer to¢

Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle , as well as ex­
haust and noise levels .
Fuel economy, environmental impact, and
wear on your engine, brakes and tires largely
depend on three factors:
- your persona l driving style
- operating conditions
- technical lim itations
If you anticipate what you need to do next and
drive economically, you can easily cut your
fuel cons umption by 10-15 percent. This sec-
Driving and environment 195
tion wi ll give you some tips on how you can
help the environment and your pocketbook.
(0 Tips
The consumption estimates as published
by ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehi­
cle load and speed, road and weather con­
dit ions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating .
.,. Avo id unnecessary accelerating and brak ing.
Vehicles use the most fue l when they are ac­
ce lerat ing. If you anticipate what is going to
happen next, you will need to brake less and,
thus, accelerate less . Let the vehicle coast
whenever possible -for example when you see
that the next traff ic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage .
.,. Try and keep well below your car's maximum
speed.
Acce lerating gently reduces fue l consump­
tion, eng ine wear, and does not disturb the
environment .
Fuel consumption, exhaust emissions and en­
gine noise increase disproportionately at high
speeds. If you drive at approximately three quarters of top speed, fuel consumption will
be reduced by one half. Never drive faster
than the posted speed l imit and weather con­
ditions permit.

short trips whenever possib le.
The
outside temperature is also critical in this
regard. Your car consumes more fuel in the
winter than in the summer .
allroad: Driving offroad
General information
Applies to vehicles: atlroad
When driving offroad, the funct ions for the
e lectronic stab ilization control (ESC) are ex­
panded. The ESC-Offroad-Mode can be activat­
ed in driving situations in which a wheel lock
or a differentia l lock function is needed
c::> page 187. In addition, your Audi provides
continuous all wheel drive .
Your Audi is however , not an offroad vehicle.
Never drive the vehicle in terrain which is not
suitable for the vehicle, or which exceeds
your driving skills. Never take any unneces­
sary risks!
After driving offroad
-After driving offroad, remove branches and
other debris from the radiator grille, under ­
body, and wheels. Look especially for objects
(stones) that have been caught in the tire
tread .
- Clean the body and the vehicle underbody
