0 ::..:: co ..... ..... -You should perform braking maneuvers for
the p urpose of clean ing the brake system
only if road conditions permit. Other road
users must not be put at risk - you may
cause an accident!
- Before descend ing a steep grade, reduce
speed and shift transm iss io n into a lower
gear or lowe r d riv ing range. Do not ride the
bra kes or hold the pedal down too long or
t oo often. This could ca use the bra kes to get
hot an d diminish brak ing efficiency.
- Do not "r ide t he b rakes" by resting your foot
on the pe dal when yo u do not inten d to
br ak e. This may cause the br akes to over­
heat, p remat ure wea r and increased stop ­
ping distance.
- Under certa in climatic and operating condi­
tions such as passing thro ugh water, driving
in heavy ra in or after washing the vehicle,
the effectiveness of the brakes can be re ­
duced. In w inte r, ice can acc umulate on the
brake pads, linings, discs and drums. Care­
fully apply brakes for a test. Brakes will dry and ice coatings w ill be cleaned off after a
few careful b rake applica tions.
- Driv ing for an ex tended period of time on
salt-covered roads witho ut using your
bra kes can also affe ct bra king efficie ncy .
C le an off a ccumula ted s alt co ating from
bra ke discs and pads with a few caref ul
bra ke app lications.
- If you dam age the fro nt sp oiler, or if yo u in­
st all a diff erent spoi le r, be sure the ai r flow
to the front brakes is not obstr ucte d. Othe r­
wise the bra ke system could overheat reduc ­
ing the e ffectiveness of the entire b rake sys­
tem.
- Failure of one brake circuit will impair the
brak ing capability resulting in an increased
stopp ing distance. Avoid driving the vehicle
and have it towed to the nearest authorized
Audi dealer or qualif ied workshop.
- Never let the veh icle roll to a stop w ith the
engi ne shut off .
-If the brake booster is not working, the
bra ke pedal m ust be pressed conside rably
harder to make up for the lac k of booster
assista nee .

Economical and environ­
mentally-friendly driving
General
Your personal style of driving will determine the
economy of your vehicle, as well as exhaust and
noise levels.
F ue l economy, environmenta l impact, and we ar
on your engine, brakes and tires la rgely depend
on three factors :
- you r persona l dr iving sty le
- operating conditions
- technical lim itations
If you anticipate what you need to do next and
drive economically, you can eas ily cut your fue l
consumption by
10-15 percen t. This section will
g ive you some tips on how you can help the envi ­
ronment and yo ur pocketbook .
(!) Tips
The consumpt ion estimates as published by
ENVIRONMENTAL PROTECTION AGENCY (EPA) and Transport Canada may not cor re­
spond to your actual consumption on the
road, which will va ry depending upon vehicle
load and speed, road and wea ther condi tions,
t rip length, etc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating.
" Avoid unnecessary accelerating a nd braking .
Veh icles use the most fuel when they are acceler ­
ating . If you anticipate what is going to happen
next , you will need to brake less and, thus, accel­
e rate less . let the vehicle coast wheneve r possi ­
b le -fo r example when yo u see that the next traf­
fic light is red .
Driving and the envir onment
Avoid full throttle
Driving at moderate speeds saves fuel and im­
proves your mileage .
"Try and keep well below your car 's maximum
speed.
Acce lerating gently reduces fuel consumption,
engine wear, and does not disturb the environ­
ment.
Fuel consumption, exhaust emissions and engine
noise increase disproport ionately at high speeds.
If you drive at approximately three quarters of
top speed, fuel consumption will be reduced by
one half. Never drive faster than the posted
speed limit and weather cond itions permit .
Reducing unnecessary idling
Even when your car is jus t idling it burns up fuel.
" Shut the eng ine off when you are not driving
the vehicle.
" Do not warm up the vehicle by lett ing the en-
gine run at idle.
It makes sense to shut off the engine in traffic
jams, when waiting for trains to pass at railroad cross ings, or at traff ic lights that have long waits
on red . Turning the engine off for just
30 -40 sec ­
onds saves more f uel than is burned starting the
. . engine again.
It takes a long time for the eng ine to warm up
fully when it is running at idle . However, wear
and noxious emissions are especially h igh when
the engine is warming up . So yo u should dr ive
away as soon as you start the eng ine and avoid
runn ing at high rpms w hile the engine is st ill
warming up .
(D Note
Do not leave eng ine idling unattended after
s tart ing. If wa rning lights sho uld come on to
i ndicate improper operation, they would go
unheeded . Extended idling also prod uces
heat, which could resu lt in overheating or
other damage to the vehicle or other proper­
ty.

lights and the license plate .
- Perform a brake test (especially after dr iving
t h rough water) .
& WARNING
-Be espec ially aware and attentive when driv­
ing under difficult conditions. Damages to
the vehicle and injuries may occur when
dr iv ing at an excessive ly high speed or w ith
incorrect dr iving maneuvers.
- Always adjust your speed and handling to
the roads, terrain, traffic and weather con­
ditions. Drive especially slow if offroad wit h
low v is ibility.
- Please note that the wheels can spin and
the vehicle can break away when the ESC
Off road Mode is switched off, especia lly
w he n t he roa d is slippery.
- Driv ing stabi lity is reduced in the ESC Off­
road mode.

Avoid harming the environme nt and take na­
ture into conside ra tion .
(D Tips
Only drive where it is allowed and always stay
on t he p rovided roads and paths.
Driver messages
App lies to vehicles: allroad
There is only one right way to drive in difficult
conditions: slowly and with caution!
When driving offroad, observe the fo llowing:
.. Never dr ive the veh icle in te rrai n which is not
s ui tab le for the vehicle, o r which exceeds your
driving skills. Never ta ke any unnecessary risks!
.. Drive slowly and ca utiously!
.. Pay attention to the
ground clearance of yo ur
vehicle! This may vary depending on the load and compos it io n of the ground and the environ­
me nt. The driver is therefore responsible for
deciding whether a vehicle can handle a specif ic
s itu atio n.
Driving and the envir onment
.. Activate the ESC-Offroad-Mode ¢ page 178 as
needed .
Difficult terrain
Never dr ive in areas t hat are not fam ilia r to you
and dr ive slow ly when off road and be prepare d
and expect the unexpected (e .g. potho les, bould­
ers, t ree stumps, etc.)
T o p reve nt the vehicle from bottom ing and avoid
damage to t he un derbody, you shou ld dr ive

Trailer mod e
Trailer mode
Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation.
If you plan to tow a trailer, please remember that
the additional load will affect durability, econo­
my and performance.
Trailer towing not only places more stress on the
vehicle, it also calls for more concentration from
the driver.
F or this reason, always follow the operating and
driving instructions provided and use common
sense.
Technical requirements
Tr aile r hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suitable
for your veh icle and trailer and must be mounted
securely on the vehicle's chassis at a technically
sound
location . Use only a trailer hitch with a re­
movable ball mount . Always check w ith the t rail­
er hitch man ufact urer to make su re that you are
using the co rrect hitch .
Do not use a bump er hit ch .
The hitch must be installed in such a way that it
does not interfere with the impact -absorbing
bumper system. No mod ificat ions should be
made to the vehicle exhaust and brake systems .
From t ime to t ime, check that a ll hitch mount ing
bolts rema in securely fastened.
When you are not tow ing a tra iler, remove the
tra iler hitch ba ll mount . This prevents the hitch
from caus ing damage shou ld your veh icle be
s truck from be hind ¢
,&..
Trailer brakes
If your trailer is equipped with a brak ing system,
check to be sure that it conforms to all regula­
tions .
190
The trailer hydraulic brake system must not be
directly connected to the vehicle's hydraulic
brake system ¢&. .
Safety chains
Always use safety chains between you r vehicle
and the trailer.
Trailer lights
Traile r lights must meet all regulations . Be sure
to check w ith your author ized Audi dealer for cor­
r ec t wiring , switches, and relays.
M irrors
If you are unable to see the traffic behind you us­
ing the regular outs ide mirrors, then you
must in­
stall extended mirrors . It is important that you
always have clear vision to the rear.
.&_ WARNING
- If a tra ile r has e lectr ica l brakes p lease no te
t hat these brakes are not activated by the
factory-fit ted contro l unit -risk of accident!
'
- After removing the trai ler hitch, do not
store it in your vehicle. In case of sudden
braking, the hitch co uld fly forward and in ­
jure you or yo ur passengers.
Operating instructions
Ma ximum traile r we ight
A trailer for your vehicle is limited to a typical
class 1 or class 2 trailer.
Trailer load distribution
Be sure the load in the trai ler is held securely in
place to p revent i t from shifting forward, back ­
ward or sideways.
Nev er allow a pa ssen ger to rid e in a trailer ¢ &.
in Driving instructions on page 191.
Engine cooling system
Towing a tra iler makes the engine work harder . It
i s important that the cooling system's perform ­
ance is up to the additional load. Make sure that
the cool ing system has enoug h fluid.

Tire pressure
When tow ing a tra ile r, infl ate the tires of yo ur
ve hicl e to the co ld tire press ure listed under "Fu ll
l oad" on the label located on the driver's side B­
pi llar (visib le when th e door is open). Inflate
tra ile r tir es to t railer and tire manufacture rs'
specifications.
Light s
The headlight settings should be checked wi th
the trai ler attached before driv ing
off . Check to
make sure both veh icle and trai ler lights are
wo rking prope rly .
Safety chains
Be s ure trai ler s afety chains are p ro p erly conne ct­
ed from the trailer to the hitc h on the vehicle .
L eave enough slack in the chains to permit turn­
ing corners . When you install safety cha ins, make
sure they w ill not drag on the road when yo u are
driving.
The chains s hou ld cross under the t railer tongue
to p revent it from dropp ing in case of separat ion
from t he hitc h.
Driving instructions
Driving with a trailer always requires extra core
and consideration.
To ob tain the best possible handling of vehicle
and trailer, please note the fo llowing :
.,. Do no t tow a lo ad ed t railer w hen yo ur car i tse lf
i s not lo ad ed.
.,. Be especia lly caref ul when passing ot he r
vehicles .
.,. Observe speed limits.
.,. Do not d rive at the maximum permissible
speed .
.,. Always apply brakes early .
.,. Moni to r th e temperature gauge .
Weight distribution
T owing a loaded trailer w ith an empty car res ults
in a high ly unstable distribution of weight . If this
cannot be avo ided, drive at very low speeds o nly
to avoid the risk of losing steering control.
Trailer mode
A "ba lanced" rig is easier to opera te and co ntrol.
This means that the tow vehicle sho uld be loaded
to the extent possib le and permissib le, w hile
keeping the trailer as light as possible under the
cir cumstances . Wheneve r poss ib le, transfer
some cargo to the luggage compartment of the
tow ve hicle while observing tongue load require­
ments and vehicle loa ding consi de rations .
Speed
The higher the speed, the mo re diff icult it be­
comes for the driver to control the r ig. Do not
drive at t he max imum permissib le speed. Reduce
you r sp eed even more if load, weathe r or wind
cond it ions are u nfavo rab le -pa rticularly when
go ing down hill.
Reduce vehicle speed
immediately if the trailer
shows the slightes t sign of sway ing .
Do not try
to stop the swaying by accelerating .
Observe speed limits . In some a reas, speeds fo r
vehicles towing trailers are lower tha n for regular
vehicles .
Always apply bra kes early . When d riving down­
hill, shift into a lower gear to use the e ngine
braki ng effect to slow the vehicle . Use of the
brakes alone can cause them to overhea t and fa il.
Coolant temperature
The coo lant tempe rature gauge c:> page 10 m ust
be obse rved caref ully. If the needle moves close
to the upper end of the scale, reduce speed im­
me diate ly and/or t urn
off th e a ir cond it io ne r .
If the coolant temperat ure warning light . in
t h e instr ument cluster starts flashing, pull
off
the road, stop and let the engine idle for about
two m inu tes to pre vent heat build -u p .
