Anticipatory driving
A vehicle uses the mos t fu el when a ccele ra tin g.
W hen yo u dr ive wi th a ntici pat ion, you do not
need to brake as ofte n an d so yo u acceler ate less .
W hen possi ble, let your vehi cle coast w it h a
gear
engaged ,
for example when you notice that the
next tra ffic light is red . This p roduces an engine
b raking effect, wh ich helps to protect the brakes
a n d tires a nd reduces t he emissions a nd f uel con­
sumpt io n to zero (fuel shut-off dur ing decelera­
tion) .
Shift efficiently
Upshift ing earlier is an effective way to save fue l.
Staying in a gear too long uses fue l unnecessari­
l y .
Press down on the acce le rato r peda l slowly and
avoid "k ic k-dow n".
Avoid full acceleration
You s hould rare ly tr ave l a t t he m axim um ve hicle
speed . High speeds cause a d isp roportionately
h ig h inc rease in fuel consumption, emissions an d
traffic no ise . Slower driving saves fuel.
Reduce idling time
T h e St art /S top system * he lps t o redu ce the i dlin g
time autom atically . In vehicles wi tho ut the Start /
Sto p system, it is eff ic ient to sw itch t he engine
off w hen stopped at ra ilroad cross ings a nd long
red lights . Depending on t he ve rsion of the en­
g ine, stopping the eng ine for as litt le as five sec­
onds once it has reached ope rat ing tempe rature
Driving
st ill saves mo re fue l th an leav ing t he en gine run ­
ning -even when taking into acco unt the amount
of ext ra fuel t hat is use d to restart t he e ngi ne.
It tak es a ve ry long time in idl e to warm the en ­
gine up to o peratin g tem perature . Wear an d
emissions are especially high in the warm -up
phase. The refore, you s hould begin drivi ng im ­
med iate ly after starting the eng ine. Avoid h igh
RPMs wh ile doing this.
Have maintenance performed regularly
By hav ing maintenance pe rformed reg ularly o n
yo ur vehicle, you can help to reduce fue l con ­
s u mption before you even sta rt to drive. The
maintenance cond ition of your vehicle not on ly
affects traffic safety and long-term va lue b ut al­
so impacts
fuel consumption . A poorly ma in­
ta ined engi ne ca n lead to fue l co nsump tion that
i s 1 0% hig her th an no rmal.
Avoid short trips
The eng ine and emissions contro l system must
r each their optima l
operating temperature to ef­
fec tively reduce consump tion and emissions .
A cold engine uses a disp roportionately high
amount of fue l. The e ngine reac hes operat ing
temperat ure and cons umption no rma lizes on ly
after app roxima tely 2 .5 m iles (4 km).
Check the tire pressure
To save f ue l, ma ke sure the ti res are always i n­
f lated to t he correct press ure
c> page 339. The
fuel consumpt io n can increase by 5% if the pres­
s ur e is on ly 0 .5 bar too low . Due to t he increased
r oll ing resis tance, low tire pressures w ill also
l ead to greate r tire
wear an d will affect dr iving
behav ior.
Do not d rive on
winter tires year- ro und , as this
will consume u p to 10% more f uel.
Eliminate unnecessary weight
S ince eve ry pou nd of ext ra weight inc reases fuel
consumption, a quick inspect io n of the luggage
compartment may be wo rth it to avoid un neces-
sary we ight .

Trail er to wing
Trailer towing
Driving with a trailer
General information
Your veh icle is primari ly intended for transport­
ing peop le and luggage. Howeve r, if you dr ive
with a tra iler , follow the techn ica l requirements ,
the operation and driving tips, and the lega l reg ­
ulations.
Dr iving w ith a trailer affects the vehicle 's fuel
consumpt ion, performance and wear. It a lso re­
quires higher concentration from the driver .
A WARNING
Do not transport any people in a trailer due to
the risk of fatal injury .
Technical requirements
Certain requirements must be met when towing
a trailer.
Trailer hitch
Only use a trailer hitch with a removab le ball
h itch mount and ball h itch. The tra ile r hitc h must
be pe rm it t ed for the vehicle, the tra iler and the
permitted tota l weight of the trailer being
pu lled . Above all, it must be secure ly and safe ly
attached to the vehicle trailer.
Never mo unt a t rai ler hitch on the bumper. The
trai ler hitc h must be mounted in a way that does
not impair the function of the bumper. Do not
make any changes to the exhaust system and the
brake system.
Check regu larly if the trai ler hitc h is securely
mounted . A lways follow the instructions given by
the trai ler hitch manufacturer .
Trailer brakes
If t he tra ile r has its own bra ke system, then fol­
low the manufacturer specifica tions. Howeve r,
the brake system on the trai ler must never be
connected to the vehicle brake system.
118
Engine cooling system
D riving w ith a tra ile r means a higher load on t he
engine and the cooling sys tem. The coo ling sys­
tem must be designed for additiona l load and
contain enoug h
coolant ¢@ .
@ Note
Longer incl ines cannot be driven wi tho ut a
suitab le cooling system, especia lly if the out ­
side temperatures are high . ot herwise, this
i ncreases the risk of eng ine damage.
Operating instructions
Several things must be noted when towing a
trailer.
Towing capacity
Yo ur vehicle can only be ope ra ted with class 1 or
class 2 trai le rs.
Load distribution
Poor cargo load and distr ib ution can negatively
i mpact vehicle handling . T o have the lowest im­
pact as poss ible, load the tra ile r according to
t h ese cr ite ria :
- Store objects preferably in the vehicle luggage
compartment . The vehicle should a lways carry
the heaviest poss ib le load and the trailer
should have t he lig htest poss ible load .
- Dist ribute the load in the t railer so that the
heavy objects a re as close to the axle as poss i­
ble.
- Secu re objects from s lid ing o ut of place.
- Ut il ize the maximum permitted tongue we ight
if poss ible .
Tire s
Set the tire pressure on your vehicle for a "full
load"; see the tire pressure
st icker ¢ page 341.
If necessary, also adjust the t ire pressure on the
trailer acco rding to the manufactu rer's recom­
mendat ion.
Winter tires should be mounted on the vehicle and on the trailer during w inter temperatures .

Assistance systems
Speed warning system
Description
Applies to: veh icles with speed warning system
The speed warning system helps you to stay be­
low a specified maximum speed that can be set,
changed or deleted in the Infotainment system.
The speed warning system warns you if you are
exceeding the maximum speed that you have set .
A warni ng tone will sound as soon as your speed
exceeds the sto red value slight ly. The
[OJ (USA
models) ;[;] (Canada models) indica to r li gh t and
the co rresponding message appear in the inst ru­
ment cluster display at the same time. The
[C]
(USA models)/ [ej (Canada mode ls) indicator
light and the message turn off w hen the vehicle
speed drops below the stored maximum speed .
Sett ing a threshold is recommended if you would
like to be reminded when yo u reach a certa in
maximum speed . Situations where you may want
to do so include driving in a country with a ge ner­
al speed limit or if there is a specified maximum
speed for winter tires.
Setting the warning thr eshold
.. Select in the Infotainment sys tem : IMENUI but­
ton
> Vehicle > left contro l button > Driver a s­
sistance

@ Tips
Regardless of the speed warning system, you
should always monitor yo ur speed using the
speedometer and make sure you are following
the legal speed limit.

speed and the distance between your vehi­
cle and other vehicles.
-For safety reaso ns, cruise cont rol should not
be used in the city, in stop-and-go traff ic, on
w inding roads and when road conditions are
poor (such as ice, fog, gravel, heavy rai n and
hydroplaning), because this increases the
r isk of an accident.

Intelligent Technology
All wheel drive (quattro)
Applies to: vehicles with all wheel drive
In oil wheel drive, oil four wheels ore powered.
General information
In all wheel drive, the driving power is divided be­
tween all four wheels. This happens automatical­
ly depending on your driving behavior as well as
the current road conditions. Also see
c:> page 148, Electronic Stabilization Control
(ESC) .
The a ll wheel drive concept is designed for high
engine power. Your vehicle is exceptionally pow­
erful and has excellent driving characteristics
both under normal driving conditions and on
snow and ice. Always read and follow safety pre­
cautions
c:> & .
Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con­
ditions. However, using winter or all season tires
on
oil four wheels in the winter is recommended,
because this will improve the
broking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
c:> page 346, Snow chains.
Replacing tires
For vehicles with all wheel drive, only whee ls with
the same rolling circumference shou ld be used.
Avoid using tires with different tread depths
c:> page 33 7, New tires or wheels.
Offroad vehicle?
Your Audi is not an offroad vehicle -there is not
enough ground clearance. For this reason, avoid
difficult terrain.
A WARNING
-Also, in vehicles with a ll wheel drive, adapt
your driv ing style to the current road and
traff ic conditions. Do not let the increased
safety provided tempt you into taking risks,
152
because this increases the risk of an acci ­
dent.
- The braking ability of your vehicle is limited
to the traction of the whee ls. In this way, it
is not different from a two wheel drive vehi­
cle. Do not be tempted to accelerate to a high speed when the road is slippery, be­
cause this increases the risk of an accident.
- Note that on wet streets, the front wheels
can "hydroplane" if driv ing at speeds that
are too high . Unlike front wheel drive
vehicles, the engine does not rev higher sud­
denly when the vehicle begins hydrop laning .
Fo r this reason, adapt your speed to the
road conditions to reduce the risk of an acci­
dent.
Energy management
Your vehicle is equipped with an intelligent ener ­
gy management system for distributing electrici­
ty. Thi s significantly improves the starting ability
and increases the vehicle battery life.
(D Tips
-If you drive short distances frequently, the
vehicle battery may not charge enough
whi le driving. As a result, convenience func­
t ions for electrical equipment may be tem­
porarily unavailable.
- The vehicle battery w ill gradually drain if
the vehicle is not driven for long per iods of
t ime, or if electrical equipmen t is used
when the engine is not running. To ensure
that the vehicle can still be started, the
electrical equipment will be reduced or
switched off.

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.
_&. WARNING -
-Never drive faster than the maximum permitted speed
for your tires. This could cause
the tires to heat up too much.
This increases the risk of an
accident because it can cause
the tire to burst .
-Always adapt your driving to the road and traffic condi-
330
tions . Drive carefully and re­
duce your speed on icy or slip­
pery roads . Even winter tires
can lose traction on black ice.
(@ Note
-Please note that summer and
winter tires are designed for
the conditions that are typical
i n those seasons . Aud i recom­
mends using winter tires dur­
ing the winter months . Low
temperatures significantly de­
crease the elasticity of summ­
er tires, which affects traction
and braking 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
t ions. The surface of the r ims
does not have sufficient corro­
sion protection for this and
could be permanently dam ­
aged by road salt or similar
substances.

Wheel s
0 US DOT number (TIN) and
manufacture date
T he manufacture date is listed on
the tire sidewall (it may only ap­
pear on the inner side of the tire) :

means, for example, that the tire
was produced in the 22nd week of
the year 2017.
@ Audi Original Tires
Audi Original equipment tires
with the designation
"AO" have
been specially matched to your
Audi. When used correctly, these
tires meet the highest standards
for safety and handling. An au ­
thorized Audi dealer or author­
ized Audi Service Facility will be
able to provide you with more in­
formation.
® Mud and snow capability
"M/5" or "M+S" indicates the tire
is suitable for driving on mud and
snow.
& indicates a winter tire.
@ Composition of the tire cord
and materials
T he number of plies indicates the
number of rubberized fabric lay­
ers in the tire . In general: the
more layers, the more weight a
tire can carry. Tire manufacturers
332
must also specify the materials
used in the tire. These include
steel, nylon, polyester and other materials.
@ Maximum permitted load
This number indicates the maxi­
mum load in kilograms and
pounds that the tire can carry.
@ Uniform t ire quality grade
standards for treadwear ,
traction and temperature resistance

@ Maximum permitted
inflation pressu re
This number indicates the maxi­
mum pressure to which a tire can
be inflated under normal operat ­
ing condit ions.

Wheels
.,.Audi recommends that you use
Audi Original Tires. If you would like to use different tires, please
note that the tires may perform
differently even if they are the
same size
¢ 11:,. .
.,. 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¢ ,&.
Because the spare tire* is differ­
ent from the regular tires instal­
led on the vehicle (such as winter
tires or wide tires), only use the
spare tire* temporarily in case of
emergency and drive carefully
while it is in use. It should be re­
placed with a regular tire as soon
as possible.
Applies to: vehicles with all wheel
drive: 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 dam­
aged by different wheel speeds. For this reason, in case of emer­
gency, only use a spare tire* that
338
is the same circumference as the
regular tires.
~ WARNING -
-Only use tire/rim combina­ tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident could result.
-For technical reasons, it is not possible to use tires from oth­
er vehicles - in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you
select have enough clearance
to the vehicle. Replacement
tires should not be chosen simply based on the nominal
size, because tires with a dif­
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of
an accident.
-Only use tires that are more than six years old when abso­
lutely necessary and drive
carefully when doing so.

Wheels
Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easi ly.
Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consist of multiple pieces . These compo­
nents were bolted together using special bolts
and a special procedure . You must not repair or
d isassemble
them ¢_&. .
_& WARNING
Wheel bolts that are tig htened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct tightening specifi­
cation, see
q page 364, After changing a
wheel.
- Always keep the wheel bolts and the
threads in the wheel hub clean and free of
grease.
- Only use wheel bolts that fit the rim.
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility. Never repair or disassemble
rims yourself, because this increases the risk
of an accident.
Winter tires
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 trac­
tion 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
¢ A in
General information on page 330.
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 341 .
346
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0.157 inch (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re­
gardless 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 .
(D 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
winter tires with the
& symbol may be per­
mitted.
Snow chains
Snow cha ins not only improve the driving in win­
ter road conditions, but also the braking.
.,. Only install snow chains on the front wheels.
This applies also to vehicles with all wheel
drive*.
.. 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 (SO km/
h). Note the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authori zed 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 0.53 inch (13.5 mm) in height, includ­
ing the chain lock .
You must remove the snow chains on roads with­
out snow . Otherwise, you cou ld impair driving
ability and damage the tires .
