-Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely.
-Avoid driving through salt water, because
this can cause corrosion.
Economical and environmentally-friendly
driving
The amount of fuel consumption, the environ­
mental impact and the wear to the engine,
brakes and tires depends mostly on your driving
style. With an anticipatory and economic driving
style, fuel consumption can be reduced by ap­
proximately 10-15%. The following tips will help
you conserve the environment and your money at the same time.
Anticipatory driving
A vehicle uses the most fuel when accelerating.
When you drive with anticipation, you do not
need to brake as often and so you accelerate less.
When possible, let your vehicle coast with a
gear
engaged, for example, when you notice that the
next traffic light is red. This produces an engine
braking effect, which helps to protect the brakes
and tires and reduces the emissions and fuel con­
sumption to zero (fuel shut-off during decelera­
tion) .
Shift efficiently
Upshifting earlier is an effective way to save fuel.
Staying in a gear too long uses fuel unnecessari­
ly .
Press down on the accelerator pedal slowly and
avoid "kick-down".
Avoid full acceleration
You should rarely travel at the maximum vehicle
speed. High speeds cause a disproportionately
high increase in fuel consumption, emissions and
traffic noise. Slower driving saves fuel.
Reduce idling time
The Start/Stop system* helps to reduce the idling
time automatically. In vehicles without the Start/
8 Stop system*, it is efficient to switch the engine 0 \.J ' Driving
off when stopped at railroad crossings and long
red lights. Stopping the engine for 30-40 sec­
onds already saves more fuel than the amount of
extra fuel needed to restart the engine.
It takes a very long time in idle to warm the en­
gine up to operating temperature. Wear and
emissions are especially high in the warm-up
phase. Therefore, you should begin driving im­
mediately after starting the engine. Avoid high
RPMs while doing this .
Have maintenance performed regularly
By having maintenance performed regularly on
your vehicle, you can help to reduce fuel con­
sumption before you even start to drive. The maintenance condition of your vehicle not only
affects traffic safety and long-term value but al ­
so impacts
fuel consumption . A poorly main­
tained engine can lead to fuel consumption that
is 10% higher than normal.
Avoid short trips
The engine and emissions control system must
reach their optimal operating temperature to ef­
fectively reduce consumption and emissions .
A cold engine uses a disproportionately high amount of fuel. The engine reaches operating
temperature and consumption normalizes only
after approximately
2 .5 miles (4 km) .
Check the tire pressure
To save fuel, make sure the tires are always in­
flated to the correct pressure
Q page 211. The
fuel consumption can increase by S% if the pres­
sure is only 0.5 bar too low . Due to the increased
rolling resistance, low tire pressures will also
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 pound of extra weight increases fuel
consumption, a quick inspection of the luggage
compartment may be worth it to avoid unneces -
sary weight.

" N .... 0 0 \.J - Trailer towing Driving with a trailer
General information
Your veh icle is primar ily intended for transport­
ing people and luggage. However, if you dr ive
with a trailer, follow the technical requirements,
the operation and driving tips, and the legal reg­
u lations.
Driving with a trailer affects the vehicle 's fuel
consumption, performance and wear. It also re­
quires highe r 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
hitch mount and ball hitch. The trailer hitch must
be perm itted for the vehicle, the trailer and the
permitted total weight of the trailer being
pu lled. Above all, it must be secure ly and safe ly
attached to the vehicle trailer.
Never mount a trailer hitch on the bumper. The
trailer hitch 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 regularly if the trailer hitch is securely
mounted. A lways follow the instructions given by
the trai ler hitch manufacturer .
Trailer brakes
If the tra iler has its own brake system, then fol­
l ow the manufacturer specifications. However,
the brake system on the trailer must never be
connected to the vehicle brake system.
Trailer towing
Engine cooling system
Driving with a trailer means a higher load on the
engine and the cooling system. The coo ling sys­
tem must be designed for additiona l load and
contain enough coo lant
i::> @ .
@ Note
Longer inclines cannot be driven without a
suitab le cooling system, especia lly if t he out­
side temperatures are high . otherwise, this
increases the risk of engine damage.
Operating instructions
Several things must be noted when towing a
trailer.
Towing capacity
Your vehicle can only be operated with class 1 or
class 2 trailers.
Load distribution
Poor cargo load and distribut ion can negatively
impact vehicle handling.
- Store objects preferably in the vehicle luggage
compartment . The vehicle should always carry
the heaviest poss ible load and the trailer
should have the lightest possible load.
- Distribute the load in the trailer so that the
heavy objects are as close to the axle as poss i­
b le.
- Secure objects from sl iding out of place .
- Ut ilize the maximum permitted tongue weight
if possible .
Tires
Set the tire pressure on your vehicle for a "full
load"; see the tire pressure sticker
c::>page 211.
If necessary, also adjust the tire pressure on the
trailer according to the manufacturer's recom­ mendat ion .
Winter tires should be mounted on the vehicle and on the trailer during winter temperatures.
Outside mirrors
If you cannot see the tra ffic behind the trailer
with the standard exterior mirrors, then you

Speed warning system
Description
Applies to: veh icles 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 sto red value slightly.
The . (USA models) I. (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.
Sett ing a threshold is recommended if you would
like to be reminded when you reach a certa in
maximum speed. S ituations where you may want
to do so i nclude driving in a country wit h a ge ne r­
a l speed limit o r if the re is a specified maximum
speed for winter tires.
Setting the warning threshold
The warning threshold is set in the Infotainment
system.

-Always pay at tentio n to the traffic around
you when the cruise contro l system is in op­
eration . You are always respons ible for your
speed and the distance between your ve hi­
cle and other vehicles.
-For safety reasons, cruise control should not
be used in the city, in stop-and-go traff ic, on
winding roads and when road conditions are poor (such as ice, fog, gravel, heavy rai n and
hyd roplaning), because this inc reases the
r is k of an accident.
-Switch the cr uise control off temporarily
when dr iv ing in turning lanes, highway exits
or in constr uction zones.

" N .... 0 0 \,;J ' All wheel drive (quattro)
Applies to: vehicles wit h 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
l y depending on your driving behavior as well as
the current road conditions. Also see
c:> page 119, Electronic stabilization control
(ESC) .
A center differential distributes the driving power
variab ly to the front and rear axle. It works to­
gether with selective wheel torque control, which
activates when driving through curves
c:>poge 119. With the sport differential*, power
distribution to the rear wheels is variable and can
be adjusted w ith drive select
c:> poge 104 .
The all wheel drive concept is designed for high
engine power. Your vehicle is exceptionally pow­
erful and has excellent driving characteristics
both under normal driv ing cond itions and on
snow and ice. Always read and fo llow safety pre­
cautions
c:> .&, .
Winter tires
By using all wheel drive, your vehicle has good
forward mot ion with standard tires in winter con­
ditions . However, in winter we recommend using
winter or all season tires on all four w heels, be­
cause this will improve the braking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
c:> page 217, Snow chains.
Replacing tires
For vehicles with all wheel drive, only wheels with
the same rolling circumference should be used .
Avoid using tires with different tread depths
c:> page 208, 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.
Intelligent Technology
A WARNING
--
- Also, in veh icles with all wheel drive, adapt
your driving style to the current road and
traffic conditions . Do not let the increased
safety provided tempt you into taking risks,
because this increases the risk of an acci­
dent.
- The braking ability of your vehicle is limited
to the traction of the wheels. 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 t his increases the risk of an accident .
- Note that on wet streets, the front wheels
can "hydrop lane" if driving at speeds that
are too high. Unlik e front wheel drive
veh icles, the engine does not rev higher sud­
denly when the vehicle begins hydroplaning.
For 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 . This significantly improves the start ing ability
and increases the vehicle battery life.
(D Tips
- If you dr ive short distances frequently, the
veh icle battery may not charge enough
w hile driving. As a result, convenience func­
tions for electr ical equipment may be tem­
porarily unavailable.
- Th e vehicle battery w ill gradually drain if
the vehicle is not driven for long periods of
time, or if electrical equipment 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.

Wheels and Tires
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-
Wheels
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
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
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
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.

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
is the same circumference as the
regular tires .
Wheels
A WARNING
-Do not use steel rims that are
17 inches or larger. Other­
wise, damage to the vehicle and an accident could result.
-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.
