conditions and off-road
General information
The operation of the Electronic Stabilization Con­
trol (ESC) is expanded for operation away from paved roads. In situations where slip or a differ­
ential locking fun ction is required , the offroad
mode can be activated ¢
page 190. Your Audi al­
so has permanent all-wheel drive in addition .
However, your Audi is not a pure offroad vehicle.
It was not built for driving under extreme condi­
tions, e.g. for tr ips that are in the nature of an
expedition .
Drive only on roads and offroad sections which
match the design of your vehicle and your abili­
ties as a driver. Never take risks!
Before driving offroad
-Check the engine oi l level, tire pressure, coo l­
ant level, and the fluid level in the windshield
washer reservo ir.
- Stow luggage items and other objects in the
luggage compartment, and secure them
against sliding around.
After driving offroad
-After trips offroad, remove any twigs and other
foreign objects from the gri ll, the underbody
and the wheels. Pay special attention to foreign
objects (stones) which have become lodged in
the tire tread.
- Clean the body and the vehicle underside, and
inspect the vehicle for possible damage.
- Clean dirty windows, headlamp lenses, rear
lights, and license plates.
- Perform a brake check (particularly after travel­
ling through water).
A WARNING
-Drive especially attentively and plan ahead
in difficult road condit ions and when off­
road. Excessive speed or incorrect maneu­
vers can cause injuries and damage to the
vehicle .
Offroad driving
-Always adapt your speed and driving style to
road, offroad, traffic, and weather condi­
tions. Drive especially slowly offroad when
your view is restricted.
- Please be aware that in offroad mode, par­
ticularly on a smooth and slippery road, the
wheels may have an increased tendency to spin and the vehicle may break away - dan­
ger of skidd ing!
- Stability is lim ited in the offroad mode .
@) For the sake of the environment
Avoid damage to the environment and re­
spect nature.
(D Tips
Only drive where it is permitted and stay on
marked roads and paths.
Explanation of some technical terms
The following data refer to ideal conditions. De­
pending on vehicle load and ground conditions
and the environment, the numbers may vary. It is

Offroad dri ving
- Ideal conditions do not prevai l offroad . Nev­
er utilize the maximum readings to their
fullest, always leave a safety reserve.
Driving tips
On poor rood ond offroad, there is always only
one motto: Plan ahead and drive slowly!
Pl ease observe the following when driv ing away
from paved roads:
.,. Drive only on roads and off road sections which
ma tch the des ign of your vehicle and yo ur abili ­
ties as a driver . Neve r take risks!
... Drive slowly and p lan ahead!
... Take into consideratio n the
ground clearan ce
of your veh icle.
.,. Activate the
offro ad mode Q page 190 as need­
ed .
.,. Use the
hill desc ent a ssis t Q page 192 when
driv ing down steep sections on hills .
Unpaved roads and offroad
Drive s low ly on unfam iliar roads and unknown
offroad sections, and look out for unexpected ob­
stacles (e .g. potholes, rocks, tree stumps, etc .) .
To prevent the veh icle from bottoming and avoid
damage to the underbody, you should d rive
stra ight across severe bumps in the ground with
only one side of the vehicle so that only two of
your wheels cross the b umps.
Drive briskly through sandy or marshy offroad
sections and do not stop , if at all possible .
Driving through water
Note the following to avoid vehicle damage when
driving throug h water, fo r example on flooded
roads:
- T he wate r must no t be any higher than the bot-
tom of the vehicle body .
- Do no t drive fas ter than wa lking spee d.
Driving on a slope
If you ever find yo urself not able to cl imb a s lope,
do not try to turn around, d rive back down in
re ­
verse .
Otherw ise, you run the risk of tipping over.
202 If the vehicle thre
atens to tip o ver when dr iving
across a slope, you must immediately stee r
downhill in the direction of the slope.
Do no t pa rk you r vehi cle on steep s lopes or
grades .
To reduce the risk of tipping over, drive on slopes
i n the d irect io n of the downwa rd slope (fa ll line) -
not cros swi se .
& WARNING
After driving thro ugh water, mud, slush, etc.,
the brakes may be slow to take effect beca use
of wet brake rotors and pads. Dry the brakes
f irst by braking carefu lly to restore the full
braking effect .
(D Note
- Vehicle components such as the engine,
transmiss ion, suspension or electrical sys­
tem can be seve rely damaged by driving
throug h water.
-Always switch off the Start-Stop-System *
when driving through water Qpage 93.
(D Tips
-Check the de pth of the water before driving
through it.
- Do not stop the vehicle, drive in reverse or
switch the engine of f whe n driving through
water.
- Keep in mind that oncom ing vehicles may
create waves that raise the water level and
make it too deep fo r your vehicle to drive
t h roug h safe ly.
-Avoid driv ing through salt water beca use it
can cause corrosion.

F ig. 189 Pe rmi tted ball posit io n of the traile r hi tch
Tr aile r to wing weights
With a f ac tor y-inst all ed or an a ft er ma rket trailer
h itch, the maximum permissib le trailer weight is
4,400 lbs (2,000 kg) . The maximum perm iss ible
unb raked trailer weight is 1,650 lbs (750 kg) .
These spec ificat ions apply when dr iv ing on roads
hav ing an incl ine of less tha n 12%.
Perm is sible tongue load
For best vehicle handling under these changed
conditions, adjust the trailer load so that the
tongue load is at the maxim um allowable or
slightly lower. You can get an approx imation of
the tongue load w ith a bathroom scale or you can
measure the load at a tr ucking company or
weighing station.
W ith a
fa ctor y-installed or an aftermarket trailer
h itch, t he maximum permissib le load on the ball
h itch may not exceed 440 lbs (200 kg).
It is rec­
ommended to use the maximum permissible
load.
Trailer load di stribution
B e su re the load in the trailer is held securely in
p lace to prevent it from s hift ing fo rwa rd, back ­
ward or sideways.
Nev er allo w a p assenge r to ride in a trail er c::> A
in Driving instructions on page 205.
Ball mount
The trailer hitch may only be used w ith suitable
ball mount and ball
c::> fig. 189 . Installat ion of
the hitch ball must be carr ied out in accordance
w ith the manufacturer 's inst ruct ions.
204
Engine cooling system
Towing a tra ile r makes t he engine work harder. It
is important that the cooling system's perform­
ance is up to the additional load . Make sure that
the cooling system has enough fluid .
Tire pressure
When towing a t railer, inflate the ti res of your
vehicle to the cold tire pressure listed under "Full
l oad" on the tire press ure label. The tire pressure
l abel is located on the driver 's side B-pillar . In­
flate tra iler tires to trailer and tire manufactur­
ers' specifications.
Lights
The head light settings shou ld be checked with
the trailer attached before driving off. Check to
make s ure both vehicle and trailer lights are
working properly.
Safety chains
Be sure tra ile r safety cha ins a re properly connect­
ed from the trailer to the hitch on the vehicle.
Leave enough slack in the chains to permit tu rn­
i ng corners . When you install safety chains, make
s u re they will not drag on the road when you are
driv ing.
The chains should cross under the trai ler tongue
to prevent it from dropping in case of separation
from the hitch.
Driving instructions
Driving with a trailer always requires extra care
and consideration.
To obtain the best possible handling of veh icle
and t railer, p lease note the following:
.., Do not tow a loaded trai ler when your car itself
is not loaded.
.., Be especially care ful when passing other
vehicles .
.., Observe speed limits.
.., Do not drive at the maximum permissible
speed.
.., Always app ly brakes early.
.., Monitor the temperature gauge.

Fuel and R efu eli ng
Gasoline additives
Applies to veh icles: w ith gaso li ne engine
A major concern among many auto manufactur­
ers is carbon deposit build- up ca used by the type
of gasoline you use.
Although gasoline grades d iffer from one manu­
facturer to another, they have certain things in
common. All gaso line grades contain substances
that can cause deposits to collect on v ita l engine
parts, such as fue l injectors and intake valves . Al­
though most gasoline brands include additives to keep engine and fuel systems clean, they are not
equally effective.
Audi recommends using TOP TIER Detergent Gas­
oline. For more information on TOP TIER Deter­
gent Gasoline, please go to the official website (www.toptiergas.com).
After an extended pe riod of using inadequate
fue ls, built-up carbon depos its can rob your en­
gine of peak performance.
(D Note
- Damage or ma lfunction due to poor fue l
quality is not covered by the Audi New Vehi­
cle Limited Warranty.
- Do not add aftermarket fuel additive prod­
ucts to yo ur fuel tank.
Diesel fuel
Applies to veh icles: w ith d iese l e ngine
Always use ULSD (Ultra Low Su lfur Diesel) No. 2 .
The ULSD No . 2 meets the ASTM D97S.
Diese l fuel with concentrations of biodiesel high­
er than S % such as 811,820 or 8100 are strictly prohibited.
Service station f uel pumps are labeled with the
correct fue l information for easy recognition by
the user.
If the diesel fuel pump is not labeled
ask the station operator what fuel is be ing dis­
pensed before filling up your vehicle .
ULSD No . 2 may not be availab le outside the USA
and Canada . Be sure to check before traveling to
other countries .
214
ULSD No. 2 can become thicke r in very cold tem ­
peratures, and this can impair the engine's start­
i ng and running. Depend ing on the season, gas
stations provide ULSD No. 2 that flows better in
cold temperatures so that you can continue oper­
at ing your vehicle as usual.
(D Note
- Your vehicle's diese l eng ine was designed
so ley for use w ith ULSD No. 2. Therefore,
never use gasoline, heating oil, other fuels
or flow improvers. These contain substances
that will severely damage the fuel system and the engine. Such damage will no t be
c ove red by your New Vehicle Limited War­
ranty .
-If you pu t any amo unt of inco rre ct fuel in
the fuel tank, do not start the engine u nder
any circumstances. Immed iate ly contact the
nearest authorized Audi dealer or author­
ized Audi Serv ice Facility for ass istance .
These fuels contain substances that can se­
verely damage the fuel system and the en­ gine if the engine is started .
Refueling
Fuel filler neck
The fuel filler neck is located on the right rear
s ide panel behind the fuel filler flap .
If the power lock ing system shou ld fai l, you can
still open the flap manually -fo r detailed instruc­
tions see
¢ page 216 .
You can find the fuel tan k capacity of your vehicle
in ¢ page277.
The label on the inside of the fuel filler flap tells
you the correct fuel for your veh icle. For more in­
fo rmat ion about fuel specifications, see
¢ page 212.
Your vehicle f uel tank has an on-board refuelling
vapor recovery system . Th is feature helps to pre­
ven t fue l vapors from escaping from the tank and
po lluting the environment wh ile you refue l yo ur
vehicle. In order to fill the tank properly wh ile
protecting the environment, p lease follow this
refue ling procedure carefully .

,&_ WARNING
Under normal operating conditions, never car­
ry additiona l fue l containers in your car. Gas
canisters and other containers used to trans­
port fuel can be dangerous. Such containers,
full or empty, may leak and could cause a fire
in a collision. If you must transport fuel to
use for your lawn mower, snow blower, etc.,
be very careful and a lways observe local and
state laws regarding the use, transportation
and storage of such fue l conta iners. Make cer­
tain the container meets industry standards
(ANSI/ASTM F852 -86) .
(D Note
Never d rive your vehicle unt il the fuel tank is
completely empty. The irregu lar supply of
fue l can cause misfiring. Gasoline cou ld enter
the exhaust system and damage the catalytic
converter.
