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 s ituations, including
when the vehicle is beginning to spin (yaw)
out of cont ro l and helps you to get the vehicle
back under control by select ively brak 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
m 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 187
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.
A lways adjust your speed and driving style to
road, traffic and weather condit ions. 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
drive r inattent io n. Instead, ESC imp roves the
poss ibility of keep ing the vehicle unde r con
trol and on the road dur ing extreme maneu
vers by using the driver's steering inp uts to
help keep the vehicle going in the intended di
rection . 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 switc hed on all the time . In certain sit
uat ions when you need less traction, yo u can
switch off ASR by pressing the button
[&I
c::> page 189, fig. 180. Be sure to switch ASR
o n again when you no longer need less t rac
t ion.
The following systems are integrated in the
ESC:
Anti-lock bra king sy stem (ABS )
ABS prevents the whee ls from locking up
whe n brak ing. The vehicle can sti ll be stee red
even dur ing hard braking. App ly steady pres
s u re to the brake pedal. Do not pump the ped
al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle.
Brake as sist sy stem
The brake assist system can decrease braking
distance. It increases brak ing power when the
driver presses the brake peda l quickly in emer
gency s ituations. You must press and hold the
brake pedal until the situation is over. In
vehicles with adapt ive c ruise control*, the
brake assist system is more sensitive if the
distance detected to the vehicle ahead is too
small.
•

188 Intelligent technology
Anti-slip regulation (ASR )
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road conditions. This makes it easier to
start, accelerat e and drive up hills .
Electronic differential lock (EDL )
The ED L brakes wheels that are spinn ing and
transfers the drive powe r to the o ther wheels.
This function is not availab le at higher speeds.
I n extreme cases , ED L automat ica lly switches
off to help keep the brake on the braked whee l
from ove rheating. EDL wi ll sw itch on aga in au
tomatically when conditions have returned to
norma l.
Steering recommendation
The ESC helps to stabilize the ve hicle by
changing the steering to rque.
In vehicles with dynam ic steering*, ESC also
he lps to stabilize the stee ring in critical s itua
tions.
Selective wheel torque control
Selective wheel torque control is used when
driving on curves . The front wheel on the in
side of the curve o r both wheels on the inside
of the curve are braked selective ly as needed.
This a llows more prec ise driving in curves. The
appl icable system may no t activ ate when driv
ing in wet or snowy condi tions .
A WARNING
- The ESC and its integrated systems can
not overcome the lim its posed by natural
physical laws. This is especia lly impor- tant on slippery or wet roads
. If the sys
tems beg in acting to stabilize your vehi
cle, you should immediately change your
speed to match the road and traffic con
ditions . 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 veh icle contro l, collision and
serio us pe rsonal inj uries.
- Always ad apt your speed to road, traffic
a nd wea ther conditions. The risk of los
ing con trol of the vehicle increases when
driving too fast, especially through
curves and on slippe ry or wet roads, and
when dr iv ing too close to vehicles up
ahead . The ESC and its integrated sys
tems cannot a lways prevent collisions -
there is still a risk of acc idents!
- Always accelerate with special care on
even, smooth su rfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even w ith
these assistan ce sys tems that cannot al
ways he lp to re duce the risk of loss of ve
h icle control.
(D Tips
- ABS and ASR o nly wo rk correctly when
all four wheel s are equipped with identi
c al tires . D iffe ren t 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 lig ht

Tires and wheels 235
If you wish to improve comfort
when operating the vehicle at
normal load (up to 2 occu
pants), you can adjust tire
pressures to those specified
for normal vehicle load. Before
operating the vehicle at maxi mum load, you must increase
the tire pressures to those
specified for maximum vehicle
load
c> .&. .
Bear in mind that the tire pres
sure monitoring system can on
ly monitor the tire pressures
you have stored. The system does not recognize the load
condition of your vehicle.
The effectiveness of the tire p ressure monitoring system
will be impaired if you store normal load pressures but then
operate the vehicle at its maxi
mum load

236 Tires and wheels
Because technical changes may
be made to vehicle equipment
during the model year, always
compare the tire size designa
tion on the tire pressure label
on your vehicle with the tires on
your vehicle . Make sure that the
tire size information on the ve hicle label is the same as the
size of the tires on the vehicle .
This is especially important if
the vehicle belongs to someone else or you bought the vehicle
with different rims/tires or you bought the vehicle as a previ
ously owned vehicle.
Remember, your safety and
that of your passengers also de pends on making sure that load
limits are not exceeded . Vehicle
load includes everybody and ev
erything in and on the vehicle .
These load limits are technical ly referred to as the vehicle's
Gross Vehicle Weight Rating
("GVWR"). The Gross Axle
Weight Rating ("GAWR") is the
maximum load that can be ap
plied at each of the vehicle's
two axles . The Gross Vehicle
Weight Rating and the Gross
Axle Weight Rating are listed on the safety compliance stick- er label located on the driver's
side B-pillar. The tire pressure
label on your Audi lists the
maximum combined weight of
all of the occupants and lug
gage or other cargo that the ve
hicle can carry. For the location
of the tire pressure label
¢ fig. 195.
&_ WARNING
-
Overloading a vehicle can
cause loss of vehicle control,
a crash or other accident, se
rious personal injury, and
even death .
- Carrying more weight than
your vehicle was designed to carry will prevent the ve
hicle from handling properly
and increase the risk of a
loss of vehicle control.
-The brakes on a vehicle that has been overloaded may
not be able to stop the vehi
cle within a safe distance.
- Tires on a vehicle that has
been overloaded can fail
suddenly causing loss of
control and a crash.
-Always make sure that the total load being transported
does not make the vehicle .,.
240 Tires and wheels
the driver observe the speci
fied tire pressure values for
the tires and the correct pressures for the function of
the tire pressure monitoring
system.
-Always inflate tires to the
recommended and correct
tire pressure before driving
off.
-Driving with underinflated tires bend more, letting
them get too hot resulting
in tread separation, sudden
tire failure and loss of con
trol.
-Excessive speed and/over
loading can cause heat
build-up, sudden tire failure
and loss of control.
-If the tire pressure is too low or too high, the tires
will wear prematurely and
the vehicle will not handle
well.
-If the tire is not flat and you do not have to change a
wheel immediately, drive at reduced speed to the near
est service station to check
the tire pressure and add air
as required.
(D Note
Driving without valve stem
caps can cause damage to
the tire valves. To prevent
this, always make sure that
factory installed valve stem
caps on all wheels are securely mounted on the valve.
@ For the sake of the environment
Underinflated tires will also
increase the fuel consump
tion.
Tires and vehicle load limits
There are limits to the amount
of load or weight that any vehi
cle and any tire can carry. Ave hicle that is overloaded will not
handle well and is more diffi
cult to stop. Overloading can
not only lead to loss of vehicle
control, but can also damage
important parts of the vehicle
and can lead to sudden tire fail
ure, including a blowout and
sudden deflation that can cause
the vehicle to crash.
Your safety and that of your passengers also depends on
making sure that load limits are~
256 Tire s and wheel s
Description
The tire pressure monitoring system monitors
th e pressure in the four tir es when driving .
The system uses sensors that measure the
temperature and pressure in the tires. Theda
ta is sent from these sensors to the control
module by rad io frequency .
The tire pressure monitoring system shows
the current pressures and temperatures
of the
tires in the Infotainment system
c:> page 256 .
It also compares the current tire pressures
with the sto red press ures and gives a warn ing
in the dr iver information system if the t ire
p ressu re is different from what is sto red
<=:> page 257.
The system does not detect if the sto red ti re
p ressu res matc h the recommended tire pres
sures . Yo u must resave the tire p ress ures
<=:> page 257:
- every time the tire pressures change, for ex
amp le when the load in the veh icle changes,
- after replac ing a tire, or
- i f wheels with new wheel sensors are used .
.,&. WARNING
- The tire pressure mo nitor ing system as
sists t he d rive r in monito ring t ire pres
s ur es. The dr iver is responsible fo r having
the tires in flated t o the co rrec t press ure.
- Do not change t he tire pressu re when the
t empe rat ure of the ti re is high. This
cou ld resul t in ser io us damage to the ti re
and even cause t he tire to burst, increas
ing th e risk of an accident.
- A tire with low pressure flexes more . This
heats the tire up too much. This could
cause the tread to separate and even
cause the tire to burst, increasing the
risk
of a n accident.
- The tire pressure mon itor ing system
does not warn about damage or defects
in the tire construct ion that could ca use
the tire to b urst, for examp le . Inspect
yo ur t ires regularly .
{® For the sake of the environment
Low tire pressure increases fuel consump
tion and tire wear .
(D Tips
- If tires are replaced, the senso rs/valves
do not need to be removed o r replaced.
Just replace the va lve stem and, if neces
sary, the valve and the whee l electronics .
If you have questions, see your a uthor
ized Aud i dea ler o r a qualified workshop .
- Us ing the tire mob ility kit can results in
an incorrect display or a ma lfunction in
t he tire pressure monito ring system .
Have the sensors replaced by an a uthor
ized Aud i dea le r o r a qua lified workshop.
