Driving
General information
Breaking in
A new vehicle must be broken in for the first 1,000 mi les (1,500 km). Do not dr ive at speeds
t hat will exceed 2/3 of the max imum pe rm itted
engine speed (RPM) for the first 600 miles
(1,000 km), and avoid fu ll acceleration during
this period . You may gradually start increasing
the RPM and the speed between 600 miles
(1,000 km) and 1,000 miles (1,500 km) .
During the first hours of use, the engine has a
higher internal friction than later on when all
moving parts have settled into place with each
other.
How the vehicle is driven d uring the first 1,000
miles (1 ,500 km) a lso affects the engine quality .
Drive at moderate engine speeds after the initial
break-in per iod, part icu larly when running a cold
eng ine . Th is will reduce eng ine wear and improve
the m ileage .
Do not drive at too
low of an engine speed (RPM).
Shift down if the engine stops running "smooth­ ly". Extremely high eng ine speeds are automati­
cally reduced .
Reducing the risk of vehicle damage
@ Note
When driving on poo r roads, by cu rbs and on
s teep ramps, make su re t hat low-hang ing
compone nts such as the spo ile r and exha ust
system do not come into contact with these
or they could be damaged. This especially ap ­
plies to vehicles with low ground clearance
and veh icles that are heavily loaded.
Warming up/cooling down
Applies to: S models
By warming up/cooling down the engine carefu l­
ly, you can help red uce unnecessary stra in o n
your veh icle when driving in a sporty sty le .
64
The eng ine speed is lim ited when the engine is
cold - the full engine output is not availab le.
When the engine is at operat ing temperatu re,
the engine speed limitation moves to a h igher
RPM range. A lso, cold t ires may not have full
road gr ipping capab ilities until they have warmed
up .
Your vehicle a lso has an after-run cooling fea­
ture . However, cooling down is still important.
The eng ine and the brakes as well as the exhaust
system and the transmission become very hot
whe n driving in a spo rty style . Before you shut
t h e ve hicle off, you should cool down the vehicle
by d rivi ng a few miles at low speeds with l igh t ac ­
ce leration.
Driving through water on roads
Note the following to reduce the risk of vehicle
damag e when driving throug h water, for exampl e
on f looded roads:
- The water must not be any higher t han the bo t­
tom of the vehicle body.
- Do not dr ive faster tha n wal king speed .
& WARNING
After driving th ro ugh water or m ud, the effec ­
tiveness of the brakes may be red uce d due to
mo isture on the brake rotors and brake pads.
A few careful brake app lications shou ld dry
off the brakes and restore the full braking ef­
fect .
@ Note
-Vehicle components such as the engine,
t ransmiss ion, suspens ion or elect rical sys­
tem can be seve rely damaged by drivi ng
throug h water .
- Always switch the Start/Stop system* off
when driving through water
¢ page 70 .
(D Tips
- Determine the depth before driving throug h
water.
- Do not stop the vehicle, drive in reverse or
switch the engine off when driving through
water.

a co .... N

-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.

yo ur speed and shift in to a lower gear with
"ti ptro n i c" .
-Do not ride the brakes o r press the brake
peda l too often or too long w hen driving
down hill. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases brak-
Driving

the brake system.
-If you m ust stop on an incline, a lways ho ld
the vehicle in place wit h the foot brake or
parking brake to prevent it from rolling
back .
-Never hold the vehicle on an incline with a
slipp ing clutch. The clutch opens automati­
cally when it becomes too hot from the

Hill descent control
The hill descent control system assists the driver
when driving down hills .
Hill descent control is act ivated when the selec­
tor leve r is in the D or S position and yo u press
the brake peda l. The transmission a utomatica lly
selects a gear that is suitable for the hi ll. Hill de ­
scent control tries to maintain the speed ach ­
ieved at the time of braking, w ith in physical and
technical lim itations . If may still be necessary to
adjust the speed w ith the brake pedal.
Hi ll descent control switches off once the hill lev-
els out or you press the accelerator pedal.
.,..

Driving
On vehicles with a cruise control system*
¢ page 84, hill descent control is also activated
when the speed is set.
A WARNING
Hill descent control cannot overcome physical
limitations, so it may not be able to maintain
a constant speed under all condit ions. Always
be ready to apply the brakes.
Shifting manually (tiptronic mode)
The tiptronic mode allows the driver to shift the
gears manually.

" 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
81

Trail er to wing
must attach additiona l exterior mirrors . Adjust
them so you have a sufficient visibility behind
you .
Exterior lighting
Follow the lega l regulat ions regard ing the light ­
ing eq uipment on your trailer . Conta ct an author ­
ized Audi dealer or authorized Audi Service Facili­
ty for more information.
Before start ing to drive, check a ll l ight ing equip­
men t on the hitc hed trailer.
The headlig ht range contro l adjusts automatical­
ly to the light range of the headl ights.
Safe ty chain s
Make su re the safety chains are correctly applied
when pulling a trailer . The chains should hang
enough so t hat the trailer can dr ive around
curves. However, they must not touch the
g round .
Air su spension
Applies to: vehicles with air suspension
The air suspension must be at the standard vehi­
cle height before you set the tongue weight on
the trailer a nd h itch the trailer ¢@ ,
¢page 106,
Raising/lowering the vehicle .
For ve hicles w ith a factory-installed tra iler hitch,
the air suspension trailer mode will automat ically
sw itch on if you connect the trailer cable to the
socket.
F or ve hicles w ith a retro fitted trailer hitch, you
must switch on the air suspension trailer mode
manually . Select in the Infota inment system:
ICARI function button > ( Car )* s yste m s contro l
button
> V ehicle setting s > Air su spen sion : trail ­
e r > On .
Switch it off again after tow ing a tra ile r.
You can also switch off tra iler mode ma nually
while driving , for example, when using a bicycle
rac k system .
If you have to drive through difficult road condi­
tions , you can raise the vehicle aga in after hitch­
ing the t rai ler or after adjust ing the tongue
weight .
82
@ Note
Applies to: vehicles with air suspension
-Changes i n temperature or load can affect
the height of the vehicle .
- Set the air suspension to the standard veh i­
cle he ight, otherwise the applicable tongue
we ight no longer appl ies to your veh icle .
(D Tips
-Use chocks when park ing on inclines if the
trai ler is loaded.
- We recommend also hav ing the vehicle in­
spected between the inspection intervals if
you are towing a trailer frequently .
- Avoid driv ing with a trai ler dur ing the veh i­
cle break-in per iod.
Driving with a trailer
Driving with a trailer requires extra caution.
Sp eed
Adhere to t he lega l speed lim its . Fo llow the legal
regu lat ions
sp ecific to the country.
As the speed increases, the dr iv ing stab il ity of
t h e tra ile r decreases. Therefore you should not
exceed the max imum lega l speed lim it w hen
t h ere are unfavorab le road, weather and/or wind
conditions. This especia lly applies when driving
downh ill.
Yo u m ust always red uce your speed as soon as
you notice even the slightest swinging motion o f
the trai ler . Never try to "straight en out" the trai l­
er by acce lerating.
The we ight d istr ibution is very poor if the vehicle
is empty and the trai ler is loaded. However if you
must drive under these circumstances, then drive
especially slowly .
Brakes
B rake in a time ly manner. Downs hift befo re dr iv ­
i ng down hill so that the engine can assist with
braking ¢&. .
When using a trailer w it h over run bra kes, fi rst
bra ke gently t hen q uick ly. This red uces the r isk of
j erking while braking if the trailer wheels lock up .
