steering wheel AUDI A6 2013 Service Manual

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.

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
r::¢, page 200. ..,_

206 Trailer towing
Always apply brakes early. When driving
downhill, shift into a lower gear to use the en­
g ine braking effect to slow the vehicle . Use of
the brakes alone can cause them to overheat
and fail.
Coolant temperature
The coolant temperature gauge¢ page 11
must be observed carefully. The coolant tem­
perature can increase if you drive on long in­
clines in a low gear at high engine speeds. Re­
duce your speed immediately if the LEDs in
the top part of the display turn on .
For more information about indicator lights,
refer to. ¢
page 16 .
A WARNING
Anyone not properly restrained in a mov­
ing vehicle is at a much greater risk in an
accident . Never let anyone r ide in your car
who is not properly wear ing the restraints
provided by Aud i.
Trailer towing tips
Important to know
Your vehicle handles differently when towing
a trailer because of the additional weight and
different weight distribution . Safety, perform­
ance and economy w ill greatly depend on how
carefully you load your trailer and operate
your rig .
Before you actually tow your trailer, practice
turn ing, stopp ing and back ing up in an area
away from traffic. Keep practicing until you
have become comp lete ly familiar with the way
your ve hicle-trai ler comb ination behaves and
responds.
Backing up is difficult and requires practice .
Backing up with a tra iler generally requi res
steering act ion opposite to that when backing
up your vehicle without a trailer.
Maintain a greater distance between your ve­
hicle and the one in front of you. You will need
more room to stop. To compensate for the trailer, you wi
ll need a larger than normal
turning radius.
When passing, remember that you cannot ac­
celerate as fast as you norma lly would be­
cause of the added load. Make sure you have
enough room to pass . After passing, a llow
plenty of room for your trailer before chang ­
ing lanes again.
Avoid jerky starts , sharp turns or rapid lane
changes.
(D Tips
- Do not tow a trailer during the break-in
period of your vehicle.
- If you tow a trailer, your Audi may re­
quire more frequent maintenance due to
the extra load¢
page 285.
Parking on a slope
Do not park on o slope with a trailer. If it can­
not be avoided, do so only after doing the fol­
lowing:
When parking:
.,. App ly the foot brake .
.. Have someone pla ce chocks under both the
vehicle and the trailer wheels.
.. With chocks in place, slowly release the
brakes until the whee l chocks absorb the
load .
.. Turn the wheels towards the curb .
.. Apply the parking brake.
.. Select the P selector lever posit ion .
When restarting after parking:
.. Apply the foot brake.
.. Start the engine.
.. Select the D/S selector lever position .
.. Release the parking brake and slowly pull
out and away from the wheel chocks .
.,. Stop and have someone retr ieve the wheel
chocks .
Ill-

-Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age .
(D Note
Please note that summe r and wi nte r tires
are designed for the cond itions that are
Glossary of tire and loading terminology
Accessory weight means the comb ined weight (in excess of
those sta ndard items which may be rep laced)
of au toma tic transmission, power steer ing ,
power brakes, power windows, power seats,
radio, and heater, to the extent that these
items are availab le as factory-installed equip­
ment (whether installed or not) .
Aspect ratio
means the rat io o f the height to the w idth of
the tire in percent . Numbers of 55 or lower in ­
dicate a low sidewall for improved steering re­
sponse and better overa ll handling on dry
pavement .
Bead
means the part of the t ire t hat is made o f
steel wires, wrapped or reinforced by ply cords
and that is shaped to fit the r im.
Bead separation
means a b reakdown of the bond between
components in the bead .
Cord means the strands forming the plies in the
tire.

typica l in those seasons . Aud i recommends
using winter tires during the winter
months . Low temperatures signif icant ly
dec rease the e lasticity of summer t ires,
which affects tract ion and brak ing ability.
If summer t ires are used i n very co ld tem ­
peratures, cracks ca n form o n the tread
bars , res ulting in perma nen t tire damage
that can cause loud driving noise and un­
bala nced ti re s. Audi i s not respon sible for
th is type of damage .
Cold tire inflation pressure
means the t ire p ress ure recommended by t he
vehicle manufacture r fo r a tire o f a des ignated
s ize t hat has not bee n driven for more than a
coup le o f miles (k ilometers) at low speeds in
the three hour period before the tire press ure
is m easured or adjusted.
Curb weight
me ans the we ight of a motor ve hicle with
st andard equipmen t incl ud ing the max imum
capacity of fuel, oi l, and coolant, air condi ­
tioning and additional weig ht of optiona l
equipment.
Extra load tire
means a t ire design to oper ate a t higher load s
and at higher inflation pressures than the cor­
responding standa rd tire . Extra load tires may
be identified as "XL", "x l", "EXTRA LOAD", o r
"RF" on the sidewal l.
Gross Axle Weight Rating ("GAWR")
me ans the load-ca rry ing capac ity of a single
axle system , measured at the tire -ground in­
te rfaces.
Gross Vehicle Weight Rating ( "GVWR ")
mea ns the maximum total loaded we ight of
the ve hicl e. .,..

Unbalanced whee ls must be rebalanced to
avoid excessive wea r on steering, suspension
and tires. A wheel must a lso be rebalanced
when a new tire is installed .
Incorrect wheel alignment
Incorrect whee l alignment can cause exces­
sive tire wear, impairing the safety o f the vehi­
cle. If tires show excess ive wear, have the
wheel alignment checked by an authorized
Audi dealer or qualified workshop .
All-wheel d rive
Vehicles w ith quattro ® must always have tires
of the same size, construction and tread type .
F or detai ls see
r=!:> page 196 .
A WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious persona l injury!
- Never drive a veh icle when the tread on
any tire is worn down to the wear indica­
tors.
- Worn tires are a safety hazard, they do not grip well on wet roads and increase
your risk of"hydrop lan ing" and loss of
co ntrol.
- Always keep chemicals that can cause
tire damage, such as grease, oil , gasoline
and brake fluid away from t ires.
- Tires age eve n if they are not be ing used
and can fail suddenly, especially at high
speeds. T ires that are more than 6 years
o ld can only be used in an emergency
and then with spe cial care a nd at lower
s peeds.
- Never mount used ti res on yo ur vehicle if
yo u a re not s ure of their "prev ious histo­
ry." Old used ti res may have been dam­
aged even though the damage cannot be
seen that can lead to s udden tire failure
and loss of vehicle control. Tires and wheels 251

When the malfunction indicator is illuminat­
ed, the system may not be able to detect or
signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea ­
sons, including the installation of replace­ ment or alternate tires or wheels on the vehi ­
cle that prevent the TPMS from function ing
properly . Always check the TPMS malfunction
tellta le after replacing one or more tires or
wheels on your vehicle to ensure that the re­
placement or alternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
Applies to vehicles: with tire pressure monitoring system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.
Fig. 196 Display : underinflatio n warning
Fig. 197 Display : Syste m malfun ctio n
Using the ABS sensors, the tire pressure moni ­
toring system compares the tire tread circum­
ference and vibration characteristics of the in­
dividual tires . If the pressure decreases in one
or more tires , th is is indicated in the instru­
ment cluster with a warning symbol
RE and a
message
¢fig . 196.
The tire pressure monitoring system must be
reset via MMI each time the pressures are ad-

TPMS indicator only monitors the tire pres­
sure that you have previously stored. You can
find the recommended tire pressures for your
vehicle on the label on dr iver's side B-pillar

Tire tread circumference and vibration charac­
teristics can change and cause a tire pressure
warning if :
- the tire pressure in one or more tires is too
low,
- the tire has structural damage,
- the tire pressure was changed, wheels rotat-
ed or replaced but the TPMS was not reset
