Driving
General information
Breaking in
A new vehicle must be broken in for the first
1,000 mi les (1,500 km). For the first 600 miles
(1,000 km), do not drive at speeds that are more
than 2/3 of the maximum permitted RPM, avoid
full acce leration, and do not tow a trailer . 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 p lace with each
other.
How the vehicle is driven during the first 1,000
miles (1,500 km) also affects the engine quality.
Drive at moderate engine speeds after the initia l
break-in period, particularly when running a cold
engine . This 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 poor roads, by curbs and on
steep ramps , make su re that low-hang ing
components such as the spoiler and exhaust
system do not come into contact with these
or they could be damaged. This especially ap­
plies to vehicles with low ground clearance
and vehicles that are heavily loaded.
Driving through water on roads
Note the following to reduce the risk of vehicle
damage when driv ing through water, for example
on flooded roads :
- The water must not be any higher than the bot­
tom of the vehicle body.
D riving
- Do not drive faster than walking speed.
A WARNING
After driv ing through water or mud, the effec­
tiveness of the brakes may be reduced due to moisture on the brake rotors and brake pads.
A few careful brake applications should dry
off the brakes and restore the full braking ef­
fect .
(D Note
Vehicle components such as the engine,
transmission, suspension or electrical system
can be severely damaged by driving through
water.
(D Tips
-Determine the depth before driving through
water.
- Do not stop the vehicle, drive in reverse or
switch the engine off when driving through
water.
- Keep in mind that oncom ing vehicles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely.
- Avoid dr iving through salt water, because
this can cause corrosion .
Economical and environmentally-friendly
driving
T he amount o f 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 examp le when you notice that the
next t raffic light is red. This produces an engine
llll-

Driving
braking effec t, which he lps to protect the brakes
and tires and reduces the emissions and fuel con­
sumpt ion to zero (fuel shut-off during dece lera­
tion) .
Shift effici en tly
Upshift ing earlier is an effective way to save fuel.
Staying in a gear too long uses fue l unnecessari ­
ly.
P ress down o n the acce le ra tor peda l slowly and
avoid " kick -down ".
Avoid full acceleration
You should rare ly trave l at the maximum vehicle
speed. High speeds cause a d isproportionately
h igh inc rease in fuel consump tion, emissions and
tr affic no ise. Slower driving saves fuel.
Reduce idling time
There are benefits to stopp ing the engine, for ex ­
ample when at railroad crossings or traffic lights
with longer red lights. Stopping the engi ne for
30 -40 seconds already saves mo re fuel than the
amount of extra fuel needed to restart the en­
gine.
It takes a very long time in idle to wa rm the en­
g ine up to ope ra ting tempe ra tu re. Wea r and
emissions are especially high in the wa rm -up
phase . Therefore, yo u should begi n driving im ­
mediately after starting the engine. Avoid high
RP Ms while doing t his .
Have maintenance performed r egularly
By having m ainten ance perfo rmed regu larly on
your ve hicle, yo u can he lp to reduce f uel con­
sumpt ion befo re yo u even start to dr ive. The
maintenance condition of your vehicle not only
affects traffic safety and long-te rm value but a l­
so impacts
fuel consumpt ion . A poorly main­
tained engine can lead to fuel consumption that
is 10% higher than normal.
Also check th e
oil level when refueling . T he oil
consumption
depends large ly on the engine load
and speed. It is normal for the oil consumpt ion
of a new eng ine to reach its lowest point only af ­
ter a certain amount of use. Therefo re, the oil
consumpt ion can o nly be properly judged after
58
approximately 3,0 00 miles (S,000 km) have been
driven .
Avoid short trips
The eng ine and exhaust clean ing system mus t
r each their optima l
operating temperature to ef­
fe ct ively reduce consump tion and emissions.
A cold engine uses a d isp roportionately high
amount of fue l. The engine reac hes operat ing
temperat ure and cons umption no rmal izes on ly
a fter approximate ly 2.5 m iles (4 km) .
Check the tire pressure
To save fuel, make sure the t ires are always in­
flated to the correct pressure ~
page 175. The
fuel consumpt ion can increase by 5% if the p res ­
s ur e is on ly 0.5 bar too low. Due to the i ncreased
rol ling resis tance, low tire p ressures w ill also
l ead to greater tire
wear and will affect driving
behavior .
Do no t drive on
winter tir es ye ar-r ound, as this
will consume up to 10% more f uel.
Eliminate unnecessary weight
S ince every po und of ext ra weight increases fuel
consump tion , a quick inspect io n of the luggage
compartmen t may be wo rth it to avoid unneces ­
s ar y we ight.
When not be ing used, a roof rack shou ld be re­
moved to decrease the w ind resistance of the ve­
hi cle. This will save yo u ap prox imately 1 2% fue l
at speeds from 62 -75 mph (100 -12 0 km/h).
Save energy
The eng ine drives the generator, which generates
e lectric ity; the fuel consumpt io n also increases
with t he demand for e lectricity . T he refore, sw itch
electrica l eq uipm ent off whe n you no longe r
need i t. Exa mples of eq uipme nt tha t uses a lo t of
energy a re air blowe rs at a high setting, the rea r
window defogger and seat heating* .
([) Note
-Do not leave engine idling un attended afte r
sta rting. If warn ing li ghts should come on
to ind icate improper ope ration, they wou ld
go unheeded . Extended idling also pro duces .,.

Trailer towing
If the tongue we ight is too low, this affects the
trai ler's handling. For driving safety, we recom­
mend to always utilize the maximum permitted
tongue we ight, but not exceed it. Yo u can reach
it, for example, by d istributing the cargo in the
tra iler cor rectly .
You can determ ine the tongue we ight, for exam­
p le, with a bathroom scale or a public weigh sta­
tion .
The permitted tongue weight for your vehicle is 220 lbs (100 kg) .
Load distribution
Poor cargo load and dist ribution can negatively
impact veh icle ha ndling. To have the lowest im­
pact as possib le, load the trai ler according to
these criteria :
- Store objec ts p refe rab ly in t he ve hicle lugg age
compartment . The vehicle shou ld always carry
the heaviest possible load and the trai ler
sho uld have the lightest possible load .
- Distribute the load in the tra iler so that the
heavy objects are as close to the axle as possi­
ble .
- Secure objects from sliding out of p lace.
- Utilize the max imum perm itted tongue we ight
i f poss ib le .
Tires Set the tire pressure on your vehicle for a "full load"; see the t ire pressu re sticker
r=:;, page 176 .
If necessa ry, also adjust t he tire p ressure on the
tr ail er according to the manufactu rer's re com­
mendation.
W inte r ti res s hou ld be mounted on the ve hicle
a nd on the trailer dur ing wi nte r temperatures.
Outside mirrors
If you cannot see the traff ic be hind the tra iler
with the standard exterior mirrors, then you must attach addit ional exte rior m irrors. Adjust
them so you have a s ufficient visibility behind
you .
Exterior lighting
Follow the legal regulat ions regarding the light ­
i n g eq uipment on your trailer. Contact an author-
74
ized Audi dealer or author ized Audi Service Facili ­
ty for more information .
Befo re st arting to dr ive , check all lighting eq uip­
ment on the hitched trailer.
The head light range cont rol ad justs automat ica l­
l y to the light range of the headlights .
Safety chains Make sure the safety chains are correct ly applied
whe n pu lling a trailer . The cha ins should hang
enough so that the trailer can drive around
curves. Howeve r, they must not touch the
ground.
(D Tips
- Use chocks when park ing on inclines if the
t railer is loaded .
- We recommend also having the vehicle in­ spected between the inspection intervals if
you a re towing a trailer frequently.
- Avoid driv ing with a tra iler dur ing the veh i­
cle b reak-in per iod.
Driving with a trailer
Driving with a trailer requires extra caution .
Speed
Adhere to the legal speed limits. Fo llow the legal
regu lations specific to the country.
As the speed increases, the dr iving stab ility o f
the trai ler decreases . Therefore you should not
exceed the maximum lega l speed limit when
there are unfavorable road, weather and/or wind
cond it ions. T his especially applies when driving
downh ill.
You m ust always reduce your speed as soon as
you notice even the slightest swinging motion of
the tra iler . Never try to "stra ighten out" the trai l­
er by acce lerating.
The weight d istribution is very poor if the vehicle
i s empty and the trai ler is loaded. However if you
must drive under these circumstances, then dr ive
especially slowly . ..,.

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 warning tone will sound as soon as your speed
exceeds the stored value slightly. The
lGJ (USA
models)
I l•j (Canada mode ls) indicator light
and a message appear in the instrument cluster
d isp lay at the same time . ThP
lGl{t] 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 yo u reach a certa in
maximum speed. Situations where you may want
to do so include driving in a country w ith a gener­
al speed limit or if there is a specified maximum
speed for winter tires.

-Always pay attention to the traffic around
you when the cruise contro l system is in op­
erat ion. You are always respons ible for your
speed and the distance between your veh i­
cle and other vehicles.
- For safety reasons, cruise control should not
be used in the city, in stop -and -go traff ic, on
w inding roads and when road conditions a re
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 cruise control off temporarily
when dr iv ing in turning lanes, highway exits
or in constru ction zones.
- P lease note that "rest ing" your foot on the
accelerator pedal un intent iona lly can result

dea ler o r autho rized Aud i Serv ice Facility fo r as ­
sis tance.
If the indicator light turns on, the steering wheel may be more diff icult to move or more sensitive
than usual. The steering wheel may also be at an
angle when dr iving straight .
Drive s low ly to an author ized Audi dealer or au­
thor ized Audi Se rvice Fac ility to have the mal­
function co rrected.
kr-ij Steering lock: System fault ! Please contact
dealer.
There is a malfunction in the electronic steering

Audi Service Facility immediately to have the
malfunction corrected.
A WARNING
-
Have the system malfunction corrected as
soon as possible by an author ized Audi dealer
or authorized Aud i Service Fac ility, as this in­
creases the risk of a n accident .
(D Tips
If the . or i1:.ij indicator light only stays on
for a short time, you may continue dr iv ing.
Intellig ent Technology
All wheel drive (quattro)
Applies to: vehicles with all wheel drive
In all wheel drive, all four wheels are powered.
General information
In all whee l drive, the dr iving power is div ided be­
tween all fou r wheels . This happens automatical­
ly depending on yo ur driving behavior as we ll as
the cur rent road conditions . A lso see ¢
page 89 .
The all whee l dr ive concept is des igned for high
engine power. Yo ur vehicle is except iona lly pow­
erfu l and has excellent driving characteristics
both under normal driving conditions and on
snow and ice. Always read and follow safety pre­ cautions
q .&, .
Winter ti res
By using all whee l drive, your veh icle has good
forward motion w ith standard tires in winter con­
ditions . However, using winter or all season tires
on
all four wheels in the winter is recommended,
because th is w ill improve the
braking effect.
Snow chains
If there a re snow chain laws, snow cha ins m ust
also be used on ve hicles with all wheel drive
¢ page 181, Snow chains .
Replacing tires
For vehicle s wi th a ll wheel d rive, o nly wheels wi th
the same roll ing ci rcumfe rence sho uld be used.
Avoid using tires with di fferen t tread depths
¢ page 173, New tires or wheels.
A WARNING
- Also, in vehicles with all whee l drive, adapt
your driving style to the current road and traffic cond itions. Do not let the increased
safety prov ided tempt you into taking r isks,
because this increases the risk of an acc i­
dent.
- The braking ab ility of your vehicle is limited
to the trac tion of the wheels. I n this way, it
is not different from a two w heel d rive vehi ­
cle. Do no t be tempte d to accelerate to a
h igh speed when the ro ad is s lippery, be -
cause t his increases t he risk of an acci den t. ...,

- Please observe information on safe driving
~page 97.
A WARNING
To help prevent poisonous exhaust gas from
being drawn into the vehicle, always keep the
rear lid closed while driving .
- Never transport objects larger than those
fitting completely into the luggage area be­
cause the rear lid cannot be fully closed .
-If you absolutely must drive with the rear lid
open, observe the following notes to reduce
the risk of poisoning:
- Close all w indows,
- Close the Panoramic sliding sunroof*,
- Open all air outlets in the instrument pan-
el,
- Switch off the air recirculation,
- Set the fresh air fan to the highest speed .
A WARNING
-
Always make sure that the doors, all win­
dows, the Panoramic sliding sunroof* and the
rear lid are securely closed and locked to re­
duce the risk of injury when the vehicle is not
being used.
- After closing the rear lid, a lways make sure
that it is properly closed and locked.
- Never leave your vehicle unattended espe­
cially with the rear lid left open. A chi ld
could crawl into the vehicle through the lug­
gage compartment and close the rear lid be­
coming trapped and unable to get out. Be­
ing trapped in a vehicle can lead to serious
personal injury.
- Never let children play in or around the vehi­
cle .
- Never let passengers ride in the luggage
compartment. Vehicle occupants must al­
ways be properly restrained in one of the ve­
hicle's seating positions.
(D Tips
- Air circulation helps to reduce window fog­
ging. Stale air escapes to the outside
through vents in the trim panel. Be sure to
keep these slots free and open.
Driving safety
-The tire pressure must co rrespond to the
load. The tire pressure is shown on the tire
pressure label. The tire pressure label is lo­
cated on the driver's side B-pillar . The tire
pressure label lists the recommended cold
tire inflation pressures for the vehicle at its
maximum capac ity weight and the tires that
were on your vehicle at the time it was man­ ufactured. For recommended tire pressures
for normal load conditions, p lease see chap­
ter ~
page 176.
' Tie-downs
The luggage compartment is equipped with four
tie-downs to secure luggage and other items.
Use the tie-downs to secure your cargo properly
~ page 102, Loading the luggage compartment.
In a collision, the laws of physics mean that even
smaller items that are loose in the veh icle w ill
become heavy m issiles that can cause serious in­
jury. Items in the vehicle possess energy which
vary w ith vehicle speed and the weight of the
item. Vehicle speed is the most significant factor.
For example, in a frontal collision at a speed of
30 mph (48 km/h), the forces acting on a 10- lb
(4.5 kg) object are about 20 times the normal
weight of the item. This means that the weight
of the item would sudden ly be about
200 lbs. (90 kg). You can imagine the injuries
that a 200 lbs. (90 kg) item flying freely through
the passenger compartment could cause in a col­
lision like th is.
A WARNING
-Weak, damaged or improper straps used to
secure items to tie-downs can fail dur ing hard
braking or in a collision and cause serious per­
sona l injury.
- Always use suitable mounting straps and
properly secure items to the tie-downs in
the luggage compartment to help prevent
items from shifting or flying forward as dan­
gerous missiles .
- When the rear seat backrest is folded down,
always use suitable mounting straps and
properly secure items to the tie-downs in

Wheels and Tires
General information
1>-(heck 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.
1>-Have faulty tires or rims re­
placed immediately.
1>-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.
1>-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-
166
tions. Dr ive carefully and re ­
duce your speed on icy or slip­
pery roads. Even winter tires
can lose traction on black ice .
(D 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.
