2017 AUDI A6 winter tires

Driving
lead to greater tire wear and will affect driving
behavior.
Do not drive on
winter tires year-round, as this
will consume up to 10% more fuel.
Eliminate unnecessary weight
Since every kilogram of extra
weight increases
fuel consumption, a quick inspection of the lug­
gage compartment may be worth it to avoid un­
necessary weight.
When not being used, a roof rack should be re­ moved to decrease the wind resistance of the ve­
hicle. You will save approximately 12% of your
fuel when at speeds from 62- 7 5 mph (100-120 km/h) .
Save energy
The engine drives the generator, which generates
electricity; the fuel consumption also increases
with the demand for electricity. Therefore, switch electrical equipment off when you no longer
need it. Examples of equipment that uses a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating*.
CD Note
Do not leave engine idling unattended after
starting.
If warning lights should come on to
indicate improper operation, they would go
unheeded. Extended idling also produces
heat, which could result in overheating or
other damage to the vehicle or other proper­
ty .
CD Note
- Have your vehicle maintained properly and
in accordance with the service recommenda­
tions in your Warranty
& Maintenance book ­
let . Lack of proper maintenance as well as
improper use of the vehicle will impair the
function of the emission control system and
could lead to damage.
- Do not alter or
remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such as
heat shields, switches, ignition wires,
68
valves, which are designed to protect your
vehicle's Emission Control System and other
important vehicle components.
(D Tips
The consumption estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehicle
load and speed, road and weather conditions,
trip length, etc.

vehicle control.
- Adjust the driver's seat or steering wheel so
that there is a minimum of 10 in (25 cm)
between your chest and the steering wheel -

Assist
Assist Speed warning system
Applies to: vehicles with speed warning system
The speed warning system helps you to stay un­
der a specified maximum speed.
The speed warning system warns you if you are
exceeding the maximum speed that you have set.
A warning tone will sound as soon as your speed
exceeds the stored value slightly.
The . (USA models)/ . (Canada models) indi­
cator light and a message appear in the instru­
ment cluster display at the same time. The •
• indicator light and the message turn off if the
speed falls back below the stored maximum
speed .
Setting a threshold is recommended if you would
like to be reminded when you reach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a gener ­
al speed limit or if there is a specified maximum
speed for winter tires.
Setting the warning threshold
The warning threshold is set in the Infotainment
system.
.. Select: the
ICARI function button > (Car)* Sys­
tems

Speed warning.
(D Tips
Regardless of the speed warning system, you
should always monitor your speed using the
speedometer and make sure you are following
the legal speed limit.

~ WARNING
-Always pay attention to the traffic around
you when the cruise control system is in op­
eration . You are always responsible for your
speed and the distance between your vehi­
cle and other vehicles.
- For safety reasons, cruise control should not be used in the city, in stop-and-go traffic, on
winding roads and when road conditions are poor (such as ice, fog, gravel, heavy rain and
hydroplaning), because this increases the
r isk of an accident.
- Switch the cruise control off temporarily
when dr iv in g in turning lanes, highway exits
or in construction zones.

ALL wheel drive (quattro)
Applies to: vehicles with all wheel drive
In oil wheel drive, all four wheels ore powered.
General information
In a ll wheel d rive, the d rivi ng power is divided be­
t ween a ll four wheels. Th is happens au tomatical­
ly depending on your driving behavior as well as
the current road cond itions. Also see
c::> page 120, Electronic Stabilization Control
(ESC) .
A center differentia l distrib utes the driv ing power
variably to the front and rear axle. It works to­
gethe r with selective wheel torq ue control, which
activates when driving through curves
c::> page 120. With the sport differentia l", power
d istr ibut ion to the rear wheels is variable and can
be ad justed w ith drive select
c::> page 104.
The a ll wheel drive concept is designed for h igh
engine power. Your ve hicle is exceptionally pow­
erful and has excellent driving characterist ics
both under normal dr iv ing condit ions and on
snow a nd ice . Always read and fo llow safety pre­
cautions
c::> ,& .
Winter tires
By us ing a ll wheel drive, your vehicle has good
forward mot io n with standard t ires in winter con ­
d itions . However, in winter we recommend using
w inter or all season t ires on all fo ur wheels, be­
cause th is w ill improve the b raking effe ct.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
c::> page 226, Snow chains .
Replacing tires
For vehicles w ith all wheel dr ive, only whee ls with
the same rolling circumference should be used .
Avoid using t ires with different tread depths
c::> page 217, New tires or wheels .

You
r A udi is no t an off road vehicle -there is not
eno ugh ground clearan ce . F or this reason, avoid
difficult terra in .
_&. WARNING
- Also, in veh icles with all wheel drive, adapt
your driving sty le to the current road and
traffic conditions. Do not let the increased
safety provided tempt you into taking r isks,
because this inc reases the risk of an acc i­
dent .
- The b raking ab ility of your vehicle is limited
to the t raction of the whee ls . In this way, i t
is not different from a two wheel d rive vehi­
cle. Do not be tempte d to accelerate to a
hig h speed when the ro ad i s slip pery, be­
cause th is increases the r is k of an accident .
- Note that on wet s treets, the front wheels
c a n " hyd ropla ne" if driv ing a t spee ds tha t
are too h igh. Unlike front wheel drive
veh icles, t he engine does not rev higher sud ­
de nly when t he vehicle begins hydroplan ing.
For this reason, adapt yo ur speed to the
road conditions to reduce the risk of an acci­
de nt.
Energy management
The starting ability is optimized
The energy management system manages the
elec trical energy distribution and optimi zes the
availability of electri cal energy for starting the
engine .
When a vehicle wi th a conventiona l energy sys­
tem is no t driven for a l ong time , the veh icle ba t­
te ry is d raine d by equ ipment ( fo r example, the
immo biliz er). In certa in circ umstances, there
could may not be enough energy to start the en­
gine.
Yo ur vehicle is equipped with an inte lligen t ener ­
gy management system fo r dist ributing elec trici ­
ty. This significantly improves the starting ability
and increases the vehicle battery life . .,.

General information
.,. Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob ­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­ proach the curb at an angle.
.,.Have faulty tires or rims re­
placed immediately.
.,.Protect your tires from oil,
grease and fuel.
.,.Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled .
.,. Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
(D N ote
-Please note that summer and
winter tires are designed for
the conditions that are typical in those seasons . Audi recom­
mends using winter tires dur­
ing the winter months . Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
2 10
and b raking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or chromed rims must not be used in winter driving condi­
tions. The surface of the rims
does not have sufficient corro­
sion protection for this and
could be permanently dam­
aged by road salt or similar
substances.

New tires or wheels
Audi recommends having all work on tires or wheels performed by
an author ized Audi dealer or au­
thorized Audi Service Facility.
These facilities have the proper
knowledge and are equipped with
the required tools and replace­
ment parts.
.,.New tires do not yet have the
optimum gripping properties. Drive carefully and at moderate
speeds for the first 350 miles
(500 km) with new tires.
.,.Use tires of the same construc­
tion, size (rolling circumference)
and as close to the same tread
pattern as possible on all four
wheels.
.,.Do not replace tires individually .
At least replace both tires on the
same axle at the same time.
.,.Audi recommends that you use
Audi Original Tires. If you would
like to use different tires, please
note that the tires may perform
Wheels
differently even if they are the
same size¢.&,. .
.,. If you would like to equip your
vehicle with a tire/rim combina­
tion that is different from what
was installed at the factory, con­
sult with an authorized Audi
dealer or authorized Audi Service
Facility before making a pur­
chase¢ .&,..
The spare tire* is different from
the regular tires installed on the
vehicle -for example, if winter
tires or wide tires are installed -
so only use the spare tire* tempo­
rarily in case of emergency and
drive carefully while it is in use . It
should be replaced with a regular
tire as soon as possible.
Applies to: vehicles with all whee l dr ive
All four wheels must be equipped
with tires that are the same brand
and have the same construction
and tread pattern so that the drive system is not damaged by
different tire speeds. For this rea­
son, in case of emergency, only
use a spare tire* that is the same
circumference as the regular
tires. ,..

Winter tires
Winter tires signif icant ly imp rove the vehicle's
handling when dr iv ing in winter conditions. Be ­
ca use of their const ru ct io n (w idth, compou nd,
t read pat tern), summer tires provide less t rac ­
tion on ice and snow .
.,. Use winter tires on all four wheels.
.,. Onl y use winter tires that a re approved fo r yo ur
veh icle .
.,. Please note that the maximum permitted
speed may be lower with winter tires
c:> _&. . An
author ized Audi dealer or authorized A udi Serv­
ice Facility can inform you about the maximum
permit ted speed for your tires.
.,. Check the tire pressure after insta lling wheels
c=> page220 .
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0.157 in (4 mm) . T he characterist ics of winter
t ir es also decrease g reatly as the tire ages, re­
gardless of t he rema in ing t read.
_& WARNING
- Never drive fas ter than the max imum pe r­
mitted speed for your tires. This could c ause
the t ires to heat up too much. This increases
the risk of an accident because it can cause
the t ire to burst.
- Always adapt your driving to the road and traffic conditions. Drive carefully and reduce
your speed on icy or slippery roads . Even
winter t ires can lose tract ion on black ice . ..,..

In o rder to minimize the oc currence of impact
damage to the tires of your vehicle, we recom­ mend that you observe the fo llow ing
precautions:
- Always maintain recommended inflation pres­
sures. Check your tire pressure every 2,000
miles (3,000 km) and add a ir if necessary .
- Drive carefully on roads with potho les, deep
gullies or ridges. The impact from driving
through or over such obstacles can damage
your tires . Impact w ith a curb may also cause
damage to your tires.
- After any impact, immediately inspect your
tires or have them inspected by the nearest au­
thorized Aud i dealer . Replace a damaged tire as
soon as poss ible .
- Inspect your t ires every 2 ,000 miles (3,000 km)
for damage and wear . Damage is not always
easy to see . Damage can lead to loss of a ir and
underinflation , which cou ld eventually cause
t ir e failure. If you be lieve tha t a tire may have
been damaged, replace the t ire as soon as pos­
s ible.
= T hese tires may wear more q uick ly than othe rs.
- Please a lso remember that, while these tires
deliver responsive hand ling, they may r ide less
comfortab ly and ma ke more no ise th an other
cho ices .
