Driving dynamic

EDL will switch on again automatically when con-
ditions have returned to normal.
Power steering
The ESC can also support vehicle stability
through steering.
Selective wheel torque control
Selective wheel torque control is used when driv-
ing on curves. Braking is targeted toward the
wheels on the inside of the curve as needed. This
allows more precise driving in curves.
Automatic post-collision braking system
The automatic post-collision braking system can
help to reduce the risk of sliding and of addition-
al collisions after an accident. If the airbag con-
trol module detects a collision, the vehicle is
braked by the ESC.
The vehicle does not brake automatically if one of
the following occurs:
— The driver presses the accelerator pedal, or
— The braking force generated by the pressed
brake pedal is greater than the braking force
that
would be initiated by the system
— The ESC, the brake system, or the vehicle elec-
trical system is not functioning

Z\ WARNING
— The ESC and its integrated systems cannot
overcome the limits imposed by natural
physical laws. This is especially important on
slippery or wet roads. If the systems begin
acting to stabilize your vehicle, you should
immediately alter your speed to match the
road and traffic conditions. Do not let the in-
creased safety provided tempt you into tak-
ing risks. This could increase your risk of a
collision.
— Please note the risk of a collision increases
when driving fast, especially through curves
and on slippery or wet roads, and when driv-
ing too close to objects ahead. There is still
a risk of accidents because the ESC and its
integrated systems cannot always prevent
collisions.

134

— Accelerate carefully when driving on
smooth, slippery surfaces such as ice and
snow. The drive wheels can spin even when
these control systems are installed and this
can affect driving stability and increase the
risk of a collision.
@) Tips
— The ABS and ASR only function correctly
when all four wheels have a similar wear
condition. Different tire sizes can lead to a
reduction in engine power.
— You may hear noises when the systems de-
scribed are working.
The So button for controlling the ESC is located
in the center console, in front of the selector lev-
er.


The ESC is automatically switched on when the
ignition is switched on. It may make sense in
some situations to limit the ESC so that the
wheels can spin:
— Rocking the vehicle to free it when it is stuck
— Driving in deep snow, on unpaved ground, or
with snow chains
Limiting ESC (sport mode)
—To limit the ESC, press the oF button briefly.
The B indicator light turns on.
— To completely reactivate the ESC stabilization
function, press the button again. The indicator
light turns off.
Switching off ESC
— To switch off the ESC, press and hold the Sor
button for more than three seconds. The B
and Ea indicator lights turn on.
— To completely reactivate the ESC stabilization
function, press the button again. The indicator
lights turn off.

Z\ WARNING
- When the ESC is switched off or limited,
there will be no vehicle stabilization or it will
be limited. The driving wheels could spin >

braking maneuvers. Stop as soon as possible
and check the wheel bolts.
— Check your wheels for damage. Have the
damaged wheels checked and/or replaced
immediately by an authorized Audi dealer or
authorized Audi Service Facility.
— Under certain conditions (such as a sporty
driving style, winter conditions, or unpaved
roads), the message may be delayed.
— The driver is responsible for ensuring that

the wheels are attached correctly.
@ Tips
— The loose wheel warning system can also
stop working when there is an ESC malfunc-
tion.

— Using snow chains may result in a system
malfunction.
Winter tires significantly improve the vehicle's
handling when driving in winter conditions. Be-
cause of their construction (width, compound,
tread pattern), summer tires provide less traction
on ice and snow.
> Use winter tires on all four wheels.
> Only use winter tires that are approved for your
vehicle.
> Please note that the maximum permitted
speed may be lower with winter tires > /\ in
General information on page 289. An author-
ized Audi dealer or authorized Audi Service Fa-
cility can inform you about the maximum per-
mitted speed for your tires.
> Check the tire pressure after installing wheels
=> page 299.
The effectiveness of winter tires is reduced great-
ly when the tread is worn down to a depth of
0.16 in (4 mm). The characteristics of winter tires
also decrease greatly as the tire ages, regardless
of the remaining tread.
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear, and fuel
consumption.
G) Tips
You can also use all season tires instead of
winter tires. Please note that in some coun-
tries where winter tires are required, only win-
ter tires with the a symbol may be permit-
ted.
Snow chains improve both driving and braking in
winter road conditions.
> Only install snow chains on the front wheels.
> Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol-
low the instructions from the manufacturer.
> Note the maximum speed of 30 mph
(50 km/h). Observe the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi dealer or author-
ized Audi Service Facility to see if you may use
snow chains.
Use fine-mesh snow chains. They must not add
more than 0.40 inch (10.5 mm) in height, includ-
ing the chain lock.
You must remove the snow chains on roads with-
out snow. Otherwise, you could impair driving
ability and damage the tires.

ZA\ WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acci-
dent.
@) Note
— Snow chains can damage the rims and
wheel covers* if the chains come into direct
contact with them. Remove the wheel cov-
ers* first. Use coated snow chains.

— Do not install and use snow chains if there is
a malfunction in the air suspension, because
the vehicle height will be very low. If you

drive with snow chains anyway, the wheel
housings and other vehicle components can
be severely damaged.
@ Tips
When using snow chains, it may be advisable
to limit the ESC > page 134.
Low-profile tires
Applies to: vehicles with low-profile tires
Compared to other tire/rim combinations, low-
profile tires offer a wider tread surface and a
larger rim diameter with shorter tire sidewalls.
This results in an agile driving style. However, it
may reduce the level of comfort and increase
road noise when driving on roads in poor condi-
tion.
Low-profile tires can become damaged more
quickly than standard tires when driving over
large bumps, potholes, manhole covers, and
curbs. Therefore, it is particularly important to
maintain the correct tire pressure > page 299.
To reduce the risk of damage to the tires and
rims, drive very carefully on poor roads.
Check your wheels regularly every 2,000 mi
(3,000 km) for damage. For example, check for
bulges/cracks on the tires or deformations/cracks
on the rims.
After a heavy impact or damage, have the tires
and rims inspected or replaced immediately by
an authorized Audi dealer or authorized Audi
Service Facility.
Low-profile tires can wear out faster than stand-
ard tires.
Uniform tire quality grading
— Tread wear
— Traction AAABC
— Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and
maximum section width > page 290, fig. 189.
306
For example: Tread wear 200, Traction AA, Tem-
perature A.
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course.
For example, a tire graded 150 would wear one
and one half (1 1/2) times as well on the govern-
ment course as a tire graded 100.
The relative performance of tires depends upon
the actual conditions of their use, however, and
may depart significantly from the norm due to
variations in driving habits, service practices and
differences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, B and C. Those grades represent the tire's
ability to stop on wet pavement as measured un-
der controlled conditions on specified govern-
ment test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance
SA.
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate-
rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden
tire failure > A\.
The grade C corresponds to a level of perform-
ance which all passenger car tires must meet un-
der the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.

changing or replacing a tire on your vehicle
=> page 308. The tire pressure monitoring system
only monitors the tire pressure you have stored.
Refer to the tire pressure label for the recom-
mended tire pressure for your vehicle
=> page 299, fig. 192.
Tire tread circumference and vibration character-
istics can change and cause a tire pressure warn-
ing if:
— The tire pressure in one or more tires is too low
— The tires have structural damage
— The tire was replaced or the tire pressure was
changed and it was not stored > page 308
— Tires that are only partially used are replaced
with new tires

sure: malfunction! See owner's manual. If fi
appears after switching the ignition on or while
driving and the @ indicator light in the instru-
ment cluster blinks for approximately one minute
and then stays on, there is system malfunction.
Try to store the correct tire pressures
= page 308. In some cases, you must drive for
several minutes after storing the pressures until
the indicator light turns off. If the indicator light
does turn off or turns on again after a short peri-
od of time, drive to an authorized Audi dealer or
authorized Audi Service Facility immediately to
have the malfunction corrected.

ZA WARNING
— If the tire pressure indicator appears in the
display, reduce your speed immediately and
avoid any hard steering or braking maneu-
vers. Stop as soon as possible and check the
tires and their pressure.
— The driver is responsible for maintaining the
correct tire pressure. You must check the
tire pressure regularly.
— Under certain conditions (such as a sporty

driving style, winter conditions, or unpaved

308

roads), the tire pressure monitoring system
indicator may be delayed.
@ Tips
—The tire pressure monitoring system can al-
so stop working when there is an ESC mal-
function.

— Using snow chains may result in a system
malfunction.
—The tire pressure monitoring system in your
Audi was calibrated with “Audi Original
Tires” > page 296. Using these tires is rec-
ommended.
Storing tire pressures
Applies to: vehicles with Tire Pressure Monitoring System
If the tire pressure changes or a tire is replaced,
it must be confirmed in the MMI.
> Before storing the tire pressures, make sure the
tire pressures in all four tires meet the speci-
fied values and are adapted to the load
=> page 299.
> Switch the ignition on.
> Applies to: MMI: Select on the home screen:
VEHICLE > Settings & Service > Tire pressure
monitoring > Store tire pressure > Yes, store
now.
@ Tips
Do not store the tire pressures if snow chains
are installed.

Emergency assistance

To benefit fully from the advantages of the uni-
directional tire design, you should replace faulty
tires as soon as possible and restore the correct
running direction on all of the tires.
> Reinstall the caps on the wheel bolts if necessa-
ry.
> Store the vehicle tool kit in its designated
place.
> If the removed wheel does not fit in the spare
wheel well, store it securely in the luggage
compartment > page 100.
> Check the tire pressure on the installed wheel
as soon as possible.
> Correct the tire pressure and store it in the MMI
=> page 308.
> The wheel bolt tightening specification must be
90 ft lbs (120 Nm). Have it checked as soon as
possible with a torque wrench. Drive carefully
until then.
> Have the faulty wheel replaced as quickly as
possible.
Space-saving spare tire
Applies to: vehicles with space-saving spare tire (compact
spare tire)
The spare tire is intended for short-term use only.
Have the damaged tire checked and replaced if
necessary by an authorized Audi dealer or author-
ized Audi Service Facility as soon as possible.
There are some restrictions on the use of the
compact spare tire. The compact spare tire has
been designed specifically for your type of vehi-
cle. Do not replace it with the spare tire from an-
other type of vehicle.
The compact spare tire is located in the luggage
compartment under the cargo floor cover
> page 316.
The tire pressure must be 61 PSI (420 kPA).
Snow chains
For technical reasons, the use of snow chains on
the compact spare tire is not permitted.
322
If you have to drive with snow chains and a front
tire fails, mount the spare tire in place of a rear
tire. Install the snow chains on the rear tire that
you removed, and install that in place of the
front tire that failed.

ZA\ WARNING
— After installing a spare tire, the tire pressure
must be checked as soon as possible.
— Do not drive faster than 50 mph (80 km/h)
with a compact spare tire. Driving faster
than that increases the risk of an accident.
— To reduce the risk of an accident, avoid hard
acceleration or braking and driving fast
around curves with the compact spare tire.
— To reduce the risk of an accident, never drive
with more than one compact spare tire.
— Normal summer or winter tires must not be
mounted on the compact spare wheel rim.

Jump starting
You should only perform the steps that follow if
you have the necessary tools and technical ex-
pertise.
If the engine does not start because the vehicle
battery is drained, you can jump start your vehi-
cle using another vehicle. Jump start cables are
needed to do this.
Both vehicle batteries must have 12 V nominal
voltage. The voltage capacity (Ah) of the vehicle
battery that is giving power must not be less
than the capacity of the drained vehicle battery.
Jump start cable
Only use a jump start cable with a large enough
diameter. Note the manufacturer's specifica-
tions.
Only use a jump start cable with insulated termi-
nal clamps.
Positive cable - usually red.
Negative cable - usually black.
