Information about
data recorded by
vehicle control
modules
Your vehicle is not equipped with a crash data
recorder. This device is installed by some vehi­
cle manufacturers to record data about crash­
es so that it can be analy zed later . Crash data
recorders are also called "Event Data Record­
ers ( EDR)" .
In some legal jurisdictions, it is not permitted
to access or download data recorded by pre­
installed crash data recorders in order to eval­
uate a crash without clear consent of the vehi ­
cle owner .
Your vehicle is not equipped with a crash data recorder. However it does contain a variety of
electronic control modules for various vehicle
systems such as engine function, exhaust
treatment or airbags and safety belts .
These electronic control modules record vehi­ cle data during normal driving for diagnosis
and repair purposes . The recording capability
of the electronic control modules is limited to
data only- no sound is recorded.
If the control
module detects a system ma lfunction or other
change in status, a very limited amount of da ­
ta is recorded for an extremely small period of
time . Data that is recorded in such a case may
include vehicle speed, d riving direction, the
load on the brakes and head restraints and
performance in the event of an acciden t or
other change in status . The stored data can
only be read or downloaded with special devi­
ces.
Electronic stabilization
control (ESC)
Description
The Electronic Stabilization Control (ESC) con­
tr ibutes to driver safety. It reduces the risk of
slipp ing and improves driving stability. ESC
Smart Technolog y 189
detects critical situations such as the vehicle
oversteering and understeering or the wheels
are spinning . The vehicle is stabilized by ap­
plying the brakes or reducing engine torque.
Once the ESC is activated, the indicator light
m blinks in the instrument cluster .
The following systems are integrated in the
ESC:
Anti-lock braking system (ABS )
ABS prevents the whee ls from locking when
braking. The vehicle can still be steered even
during hard braking. Apply steady pressure to
the brake pedal. Do not pump the pedal. A
pulsing in the brake peda l indicates that the
system is acting to stabilize the vehicle.
Brake assi st sys tem
The brake assist system can decrease braking
distance. It increases braking power when the
driver presses the brake pedal quickly in emer­
gency situations. You must press and hold the brake pedal until the dangerous situation is
over . In vehicles with adaptive cruise control*,
the brake assist system is more sensit ive if the
distance detected to the vehicle ahead is too
small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin spinning and adapts the force to
the road conditions . This makes it easier to
start , accelerate and dr ive up inclines .
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or wheels if the vehicle is equ ipped with
all wheel drive*). This function is not available
at higher speeds .
In extreme cases, EDL automatically switches
off to keep the brake on the braked wheel
from overheating . The vehicle is still working
correctly. EDL will switch on aga in automat i­
cally when cond itions have returned to nor-
mal. .,..

204 Trailer towing
different weight distribution. Safety, perform ­
ance and economy wi ll greatly depend on how
carefu lly you load your trailer and operate
your rig.
Before you actually tow your trailer, practice
turning, stopping and backing up in a n area
away from traffic. Keep practicing until you
have become comp letely fam iliar with the way
your veh icle-trailer comb ination behaves and
responds.
Backing up is d iff icult and requires practice.
Backing up with a tra iler genera lly requires
steering action opposite to that when back ing
up your veh icle without a trailer.
Maintain a greater distance between your ve­
h icle and the one in front of you. You will need
more room to stop. To compensate for the
trailer, you will need a larger than normal
turning radius.
When passing, remember that yo u cannot ac ­
celerate as fast as you normally would be­
cause of the added load. Make sure you have
enough room to pass. After passing, allow
p lenty of room for your tra iler before chang­
ing lanes aga in.
Avoid jerky starts, sharp turns or rapid lane
changes.
(D Tips
- Do not tow a tra iler dur ing the break-in
period of you r vehicle.
- If you tow a trailer, your Audi may re­
quire more frequent maintenance due to
the ext ra load
¢ page 289.
Parking on a slope
Do not park on a slope with a trailer. If it can­
not be avoided, do so only after doing the fol­
lowing:
Wh en park ing:
.. Apply the foot brake .
.. Have someone place chocks under both the
vehicle and the trailer wheels. ..
With chocks in place, slowly release the
brakes unti l the whee l chocks absorb the
load.
.. Turn the whee ls towards the curb.
.. App ly the parking brake.
.. Select the P selector lever posit ion.
When re starting afte r park ing :
.. App ly the foot brake.
.. Start the engine.
.. Select the D/S se lector lever position.
.. Release the parking brake and s lowly pull
out and away from the wheel chocks .
.. Stop and have someone retr ieve the wheel
chocks .
@ Tips
If you move the selector leve r of the auto­
matic transmission to P befo re applying
the pa rking brake and before bloc king the
whee ls, you may h ave to use more force
la ter to move the lever out of the P posi­
tion .

244 Tires and wheels
The correct tire pressure for the
spare wheel is located on a la­
bel on the driver's side 8-pillar .
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 8-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. 168.
A 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.

248 Tires and wheels
also lead to sudden tire fail­ure, including a blowout
and sudden deflation, caus­ ing loss of vehicle control.
-The driver is responsible for the correct tire pressures for
all tires on the vehicle. The
applicable pressure values
are located on a sticker on
the driver's side B-pillar.
-Only when all tires on the vehicle are filled to the cor­
rect pressure, the tire pres­
sure monitoring system can
work correctly.
-The use of incorrect tire
pressure values can lead to
accidents or other damage.
Therefore it is essential that
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 .

reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your veh icle has also been equ ipped with a
TPMS malfunction indicato r to indica te when
the system is not operating properly . The
TPMS malfunction indicator is combined with
the low tire pressure tellta le . When the sys­
tem detects a malfunct ion, the telltale will
flash for approximately one minute and then
remain cont inuous ly illuminated. This se ­
quence will continue upon subsequent vehicle
start-ups as long as the ma lfunction ex ists .
When the malfunct ion indicator is illuminat­
ed, the system may not be able to detect or
sig nal low t ire pressure as intended . TPMS
malfunct ions may occur for a variety of rea­
sons, including the installa tio n of replace­
ment or a lternate tires or whee ls on the veh i­
cle that prevent the TPMS from funct ion ing
properly. Always check the TPMS malfunction
tellta le after replacing one or more tires or
wheels on your veh icle to ensure that the re­
placement or alternate tires and wheels allow
the
TPMS to continue to function properly.

266 Tire s and wheels
& WARNING
-If the tire pressure warning light ti] in
the instrument cluster turns on, the
pressure in one or more tires is too low.
Reduce the vehicle speed immediately
and avoid any hard steering or braking
maneuvers . Stop as soon as possible,
check the t ire and inflate the tire to the
correct pressure, which is specified on
the tire pressu re label on the veh icle
¢ page 240. Driving with a t ire with low
pressure causes the tire to overheat and
can result in failure of the tire . Low pres ­
sure can a lso have a negative effect on
the driving and braking behavior of the
vehicle.
- The driver is responsible for maintaining
the correct tire pressures. You must
check the t ire pressures regularly.
- Under certain conditions (such as a spor­
ty driving style, winter conditions or un­
paved roads), the pressure monitor ind i­
cator may be delayed .
- Ask your author ized dealer if run-flat
t ires may be used on your vehicle.
- The tire pressure monitoring system can
also stop work ing when there is an ESC
malfunction.
- Using snow chains may result in a system
malfunction.
- The tires with the identification "AO" or
"RO" ¢ page 254 have been matched
with your Audi tire pressure monitoring
system. We recommend that you use
these tires.
- The tire pressure monitoring system can
only mon itor the t ire pressure of the
driving tires . Check the tire pressure of
the spare wheel in the luggage compart­ ment so that if necessary it is ready for
us e.
