2013 AUDI A6 differential

ESC includes and/or works together with the
anti-lock brake system (ABS) , brake assist sys ­
tem, anti -slip regulation (ASR) , electronic dif­
ferential lock (E DL) and e lectronic interaxle
d ifferential lock*. ESC is swi tched on all the
time. In certain situat ions when you need less
traction , you can switch off ASR by pressing
the button
[ru ~ fig . 177 . Be sure to switch
ASR on again when you no longer need less
traction.
Anti-lock braking system (ABS)
ABS prevents the wheels from locking up
when braking. The vehicle can still be steered even during hard braking . Apply steady pres­
sure to the brake pedal. Do not pump the ped­
al. A puls ing in the brake pedal indicates that
the system is he lping you to brake the vehicle.
Brake assist system
The brake assist system can decrease brak ing
d istance.
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 situation is over . In
vehicles with adaptive cruise control* , the
brake assist system is more sensitive if the
d istance detected to the vehicle ahead is too
small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road condit ions. This makes it eas ier to
s tart, accelerate and drive up hills.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinn ing and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
all-whee l drive*. This function is available up
to about 75 mph (120 km/h).
I n extreme cases , EDL automatically switches
off to help keep the brake on the braked wheel
from overheating. EDL wi ll switch on again au­
tomatically when conditions have returned to
normal.
Intelligent technology 193
Electronic interaxle differential lock*/
selective wheel torque control*
The electronic interaxle differential lock (front
whee l drive) or the se lective wheel torque
cont rol (all-wheel dr ive) operates when dr iv­
ing through curves . The front wheel on the in­
s ide of the curve or both wheels on the inside
of the curve are braked selectively as needed .
T his min imizes sliding in the front wheels and
allows for more precise driving through
curves . Th e applicable system may no t acti­
vate when driv ing in wet or snowy conditions.
A WARNING
-
-ESC, ABS, ASR, EDL and the electronic in­
teraxle differential lock function* cannot
overcome the laws of physics. This is es­
pecially important on slippery or wet
roads . If the systems begin acting to sta­
bilize your vehicle, you should immedi­
ately change your speed to match the
road and traffic conditions. Do not let
the increased safety provided by these
systems tempt you to t.;1ke risks. Doing
so will increase the risk o f a loss of vehi­
cle control, collision and serious personal
injuries.
-Always adapt your speed to road, traffic
and weather conditions . The risk of los­
ing control of the vehicle increases when
driving too fast, espec ially through
curves and on slippery or wet roads, and
when dr iving too close to vehicles up
ahead . ESC, ABS, the brake assist sys­
tem, EDL, ASR and the elec tronic inter­
axle differential lock function* cannot
prevent collisions .
- Always accelerate with special care on
even, smooth surfaces 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 -
hicle control. .,.

196 Intellig ent technolog y
-Never let the vehicle roll to a stop with
the engine shut off.
- If the brake booster is not working, for
example when towing your vehicle, or
because the brake booster has somehow
been damaged, the brake pedal must be
pressed considerably harder to make up
for the lack of booster assistance .
Electro-mechanical
power assist
The electro-mechanical power assist helps
the driver when steering.
Power stee ring adapts electronically based on
the veh icle speed.
Indicator lights and messages
• Steerin g d efecti ve! Stop th e vehicl e
If this indicator light turns on and stays on
and this message appears, the power steering may have fa iled.
Do
not continue driving . See your authorized
Aud i dealer or other qualified repa ir facility
for assistance.
lor-ij St eerin g: S yste m malfun ction ! You m ay
c ont inue driv ing
If the indicator light turns on and the mes ­
sage appears, the steering may be more diffi­
cult to move or more sensitive than usual.
Drive s low ly to your author ized Audi dealer or
q ua lified workshop to have the malfunction
corrected .
(D Tips
If the . or 'Iij indicator light only stays
on for a shor t time, you may contin ue driv­
ing .
Driving with your
quattro ®
Applies to vehicles : with all-wheel drive
With all-wheel drive , all four wheels are driv­
en .
General info rmation
With a ll Wheel Drive, power is distributed to
all four wheels. This happens automatically
depending on your driving style and the road
condit ions at the time. See also ¢
page 192.
With the sport differential*, power distribu­
t ion to the rear wheels is va riable and can be
adjusted with Audi drive select*
r::¢, page 98.
Always read and follow safety precautions
Q _& .
Winter tires
When driving in the winter, your vehicle with
all-wheel drive has an advantage, eve n wit h
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-sea ­
son tires) for improved driveability and brak ­
ing : these tires must be mo unted on
all fou r
wheel s. See also ¢ page 255 , Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this no rma lly also app lies to ve hicles
with all-wheel drive r::¢,
page 256, Snow
chains.
Replacing wh eels /tires
Vehicles with all-wheel drive m ust always
have ti res of the same s ize. A lso avo id tires
with different t read depths . For detai ls see
page r::¢,
page 251, New tires and replacing
tires and wheels .
Off-Road driving?
You r Audi does not have e nough ground clea r­
ance to be used as an off-road vehicle . It is
t h erefore best to avoid rough tracks and un ­
even terrain as much as possib le . Also refer to

For your safety, we recommend that you have
your authorized Audi dealer replace burned out bulbs for you.
It is becoming increas ingly more and more
d iff icu lt to replace vehicle light bulbs since in
many cases, other parts of the car must first
be removed before you are able to get to the
bu lb. Th is applies especially to the light bu lbs
in the front of your car which you can on ly
reach through the engine compartment.
Sheet metal and bulb ho lders can have sharp
edges that can cause serious c uts, and parts
must be correctly taken apart and then prop­
erly put back together to help prevent break­
age of parts and long term damage from wa­
ter that can enter hous ings that have not been
properly resealed .
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for you, since your dealer has the proper tools,
the correct bulbs and the expertise.
G as discharg e la mps (X enon light s):
Due to the high electrical voltage, have the
bulbs rep laced by a qualified technician .
Headlights with Xenon light can be identified
by the high voltage sticker.
LED headlights * require no maintenance .
P lease contact your authorized Audi dealer if a
bu lb needs to be replaced.
A WARNING
Contact with high-voltage components of
the electrical system and improper re­
placement of gas discharge (Xenon) head-
Fu ses and bulb s 273
light bulbs can cause serious personal in­
jury and death.
- Xenon bulbs are pressurized and can ex­
plode when being changed.
- Changing Xenon lamps requires the spe­
cial tra ining, instructions and equip­
ment.
- On ly an authorized A udi dealer or other
qualified workshop should change the bulbs in gas discharge lamps.
A WARNING
There are parts with sharp edges on the
openings and on the bulb holders that can
cause ser ious cuts.
- If you are uncertain about what to do,
have the work performed by an author­
ized Audi dealer or othe r qualified work­
shop. Ser ious personal in jury may result
from imprope rly performed wo rk.
Q) Tips
- If you must replace the light bulbs your­
self, always remember that the eng ine
compartment of any vehicle is a hazard­
ous area to work in. A lways read and
heed all WARN INGS
