Driving tips
On poor road and offroad, there is always on­
ly one motto : Plan ahead and drive slowly!
P lease obse rve the following when dr iving
away from paved road s:
• Drive only on roads and offroad sections
which match the design of your vehicle and
your abilities as a driver. Never take risks!
• Drive slowly and plan ahead!
• Take in to consideration the
g round cl ea r­
a nc e
of your vehicle .
• Activate the
offroad m ode Q page 223 as
needed.
• Use the
hill desce nt control ~ page 225
when driving down steep sect ions on hills.
Unp aved road s and offroad
Drive slowly on unfamiliar roads and unknown
offroad sections, and look out for unexpected
obstacles (e.g. potho les, rocks , tree stumps ,
etc .).
To prevent the vehicle from bottom ing and
avoid damage to the underbody, you should
d rive st ra ight ac ross severe bumps in the
g round with on ly one s ide of the vehicle so
that on ly two of your wheels cross the bumps. Drive brisk
ly through sandy or marshy offroad
sections and do not stop , if at all possible .
Driving through w ater
Note the following to avoid veh icle damage
when d riving through wate r, for example on
flooded roads :
- The water must not be any higher than the
bottom of the vehicle body.
- Do not dr ive faster than walk ing speed .
Driving on a slope
If you ever find you rself not able to climb a
s lope, do not try to turn around, drive back
down in
r e v erse . Otherwise, you run the r isk
of tipp ing over .
If the veh icle th re at en s to t ip ov er whe n
dr ivin g a cross a slop e, you mus t immediate ­
ly ste er downhill in the dir ection of th e
s lop e.
Do not park your vehicle on steep slopes or
grades .
To reduce the risk of t ipping over, drive on
s lopes in th e direction of the downward s lope
(fall line) -
not c ross wise.
A WARNING
-After driv ing through water, mud, slush,
etc ., the brakes may be s low to take effect
because of wet brake rotors and pads . D ry
the brakes first by brak ing carefully to re­
store t he fu ll braking effect.
(D Note
Vehicle components such as the eng ine,
transmission, suspension or e lectrica l sys­
tem can be severe ly damaged by dr iv ing
th rough water .
(D Tips
-Check the depth of the water before d riv­
ing through it .
- Do not stop the vehicle, drive in reverse or switch the engine off when driving
through water.

238 Trailer towing
Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a trailer, p lease remember
that the additional load will affect durability,
economy and performance .
Trailer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
For this reason, always follow the operating
and driving instructions provided and use
common sense.
@ Note
If you are going to tow a trai ler, you must
activate the trailer operation mode
c:::> page 161, Towing a trailer.
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suita­ ble for your vehicle and trailer and must be
mounted securely on the vehicle's chassis at a
technically sound location . Use only a trailer
hitch with a removable ball mount. Always
check with the trailer hitch manufacturer to
make sure that you are using the cor rect
hitch.
Do not use a bumper hitch.
The hitch must be installed in such a way that
it does not interfere with the impact-absorb­
ing bumper system. No modifications should
be made to the vehicle exhaust and brake sys­
tems. From time to time, check that all hitch
mounting bolts remain securely fastened.
When you are not towing a trailer, remove the
trai ler hitch ball mount. This prevents the
hitch from causing damage should your vehi­
cle be struck from behind
c:::> A.
Trailer brakes
If your trailer is equipped with a brakin g sys­
tem, check to be sure that it conforms to all
regulations.
T he trailer hydraulic brake system must not be
directly connected to the vehicle's hydraulic
brake system
c:::> A .
Safety chains
Always use safety chains between your veh icle
and the tra iler.
Trailer lights
Trailer lights must meet all regulations. Be
sure to check with your authorized Audi dealer
for correct wiring, sw itches, and relays.
Mirrors
If you are unable to see the traffic behind you
using the regular outside mirrors, then you
must install extended mirrors.
It is important
that you always have clear v is ion to the rear .
A WARNING ,-
- If a trailer has electrical brakes please
note that these brakes are not activated
by the factory-fitted control unit -risk of
accident!
- Afte r removing the trailer hitch, do not
store it in yo ur vehicle. In case of sudden
braking, the hitch could fly forward and
injure you or your passengers.
- Never install a "weight distributing" or
"load equalizing" trailer hitch on your ve­
hicle. The vehicle was not designed for
these kinds of trailer hitches. The hitch
attachment can fail, causing the trailer
to tear loose from the vehicle.
- The Gross Vehicle Weight Rating for your
vehicle, found on the safety compliance
label on the driver's side B-pillar, must
never be exceeded under any circumstan­
ces. Exceeding the Gross Vehicle Weight
Rating of your vehicle is likely to damage
your vehicle, and such damage will not
be covered by your Limited New Vehicle
-
Warranty. Exceeding the Gross Vehicle ~

chains, make sure they wi ll not drag on the
road when you are driving .
The cha ins shou ld cross under the tra ile r
tongue to prevent it from dropping in case of
separation from the hitch.
0 Note
If you are going to tow a tra ile r, you must
activa te the trailer operation mode
~ page 161, Towing a trailer.
Driving instructions
Driving with a trailer always requires extra
cor e and consid eration.
To obta in the best poss ible handling of vehicle
and tra ile r, p le ase no te the following:
.. Do not tow a loaded tra iler when your car it­
self is not loaded.
.,. Be especia lly careful when pass ing othe r
vehicles .
.. Observe speed limits.
.. Do not driv e at the maximum p ermissible
speed.
.. Always apply brakes early.
.. Monitor the temperature gauge.
Weight di stributio n
Towing a loaded trai ler with an empty ca r re­
sults in a high ly unstable distribution of
weight . If this cannot be avoided, drive at very
l ow speeds only to avoid the risk of losing
steering control.
A "balanced" rig is eas ier to operate and con ­
trol. This means that the tow vehicle should
be loaded to the extent possible and permiss i­
ble, while keeping the trailer as light as possi­
b le under the circumstances. Whenever possi­
b le, transfer some cargo to the luggage com­
pa rtment of the tow veh icle wh ile observing
tongue load requirements and vehicle loading
considerations .
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the rig . Do not
drive at the maximum permiss ible speed . Re- duce your speed even more i
f load, weather or
wind conditions are unfavorable - particularly
when going downhill.
Red uce veh icle speed
immediately if the trail­
er shows the slightest s ign of sway ing.
Do not
t ry to stop the swa ying by acceleratin g.
Observe speed limits. In some a reas, speeds
f or vehicles tow ing tra ile rs are lower than for
r egular vehicles.
Always apply brakes early. When driving down hill, shift into a lowe r gear to use the en­
gine braking effect to s low the vehicle . U se o f
the brakes alone can cause them to overheat
and fail.
Coolant temperature
T he coo lant tempe ratu re gauge ~ page 10
must be observed caref ully. If the need le
moves close to the upper end of the scale, re­
duce speed immediately and/or turn off the
air conditioner.
If the coolant temperature warn ing light in
the instr ume nt cluster starts flashing., pull
off the road , stop and let the engine
idle for
about two min utes to prevent heat build -up .
A WARNING "--
Anyone not proper ly restrained in a mov-
i ng vehicle is at a much greater risk in an
accident. Never let anyone ride in your car
who is not properly wearing the restraints
p rov ided by Audi .
Trailer towing tips
Important to know
Your vehicle handles d ifferently when towing
-
a trai ler because of the additional weight and
different weight distr ibut ion. Safety, perform­
ance and economy will great ly depend on how
ca refully you load your tra iler and operate
yo ur rig .
Before you act ua lly tow your tra iler, practice
turning, stopping and backing up in an area
away from traffic. Keep pract ic ing unt il you

Such damage will not be covered by your
New Vehicle Limited Warranty.
- If you p ut any amount of incorrect fuel in
the fue l tank, do not start the engi ne un­
der any circumstances. Immediately con­
tact the nearest authorized Audi dealer
or authorized Audi Service Facility for as­
s istance. These fuels contain substances
that can severely damage the fuel sys­
tem and the engine if the engine is start­
ed.
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap.
If the power locking system should fail, you
can st ill open the flap manually -for detailed
instructions see
c;,page 252.
You can find the fue l tank capacity of your ve­
hicle in
c;,page 325.
The label on the inside of the fue l filler flap
tells you the cor rect fuel for your vehicle. Fo r
more information about fuel specifications,
see
c::> page 248.
Your veh icle fuel tank has an on-board refuel­
ling vapor recovery system. This feature helps
to prevent fu el vapors from escaping from the
tank and polluting the environment while you refuel your vehicle. In order to fill the tank
properly whi le protecting the environment,
please follow t his refueling procedure careful­
ly .
A WARNING
Under normal operating conditions, neve r
carry additiona l fuel containers in you r car.
Gas canisters and other containers used to
transport fuel can be dangerous. Such con­
tainers, full or empty, may leak and could
cause a fire in a collision. If you must
transport fue l to use for yo ur lawn mower,
snow blower, etc., be very careful and al­
ways observe local and state laws regard­
ing the use, transportation and storage of such
fuel containers . Make certain the con­
tainer meets industry standards (ANSI/
ASTM F852 -86).
(D Note
Never drive your vehicle until the fue l tank
is completely empty. The irregu lar supply
of fue l can cause misfiring. Gasoline could
enter the exhaust system and damage the
catalytic converter .

~ Check the label on the inside of the fuel fi ll­
er flap to determine if the vehicle must be
fueled with gasoline or diesel fuel.
Refuelling procedure
~ Insert the fuel nozzle from the gasol ine
pump into the fue l filler neck as far as it will
go.
~ Se lect a medium refuelling rate so that the
no zzle switches off automatica lly when the
tank is full.
Putting the fuel cap back on
~ After filling your tank, twist the fuel fi ller
cap clockwise as far as it will go.
~ Close the fuel filler flap.
To avoid fuel spi lling or evaporating from the
fuel tank always close fuel fi ller cap properly
and comp lete ly. An improperly closed fuel fill­
er cap may also cause the M IL lamp
r=) page 2 7
to come on (only vehicles with gasoline en­
gine) .
A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause
severe burns and other injuries .
- Failure to shut the engine off while refu­
eling and/or to insert the pump nozzle
fully into the fuel filler neck could cause
fuel to spray out of f iller neck or to over­
flow. Fuel spray and ove rflow ing fuel can
cause a fire.
- Never use a cellular telephone wh ile re­
fueling. The electromagnetic radiation
can cause sparks that can ignite fue l va­
pors and cause a fire.
- Never get back into you r vehicle while re­
fueling. If in exceptiona l circumstances
you must get back in your vehicle whi le
refueling, make certain that yo u close
the door and touch metal to discharge
static electricity before touching the fill­
er nozzle again. Static electricity can
cause sparks that can ignite fuel vapors
released during refueling.
Fuel supply and filling your fuel tank 251
-Never smoke or have an open flame any­
where in or near your vehicle when refu­
eling or filling a portable fuel conta iner .
- For your safety, we strongly recommend
that you do not travel with a portable
fuel container in your vehicle . The con­
tainer, full or empty may leak and could
cause a fire, especially in a crash.
- If, under exceptional circumstances, you
must transport a portable fuel container,
please observe the following:
- Never fill a portable fuel container
while it is anywhere in or on the vehicle
(for example, in the luggage compart­
ment, or on the trunk). Stat ic electrici­
ty can build up while filling and can ig­
nite fuel vapors causing a fire .
- Always place a portable fuel conta iner
on the ground before filling.
- Always keep the filler no zzle complete­
ly inside the portable container before
and dur ing filling .
- If filling a portable container made of
metal, the f iller nozzle must always be
in contact with the conta iner . This will
help prevent static electric ity from d is­
charging and cause a fire .
- Never spill fue l inside the vehicle or
luggage compartment. Fuel vapors are
highly flammable .
- Always observe local and state/provin­
cia l laws regarding the use, storage
and transportation of fuel containers.
- Make certain the fuel container meets
in dustry standa rds (ANSI/ AS TM
F852-86).
(D Note
If any fuel has spilled onto the car, it
shou ld be removed immediately to prevent
damage to the paint.
@ For the sake of the environment
As soon as the correctly operated nozzle
switches off automat ica lly for the first
time, the tank is full. Do not try to add
more fuel because fuel may spill out. In •
•

252 Fuel supply and filling your fuel tank
addition, the expans ion space in the fuel
tank will be filled -causing the fuel to
overflow when it becomes warm and pol­
lute the environment.
@ Tips
- Running your engine while refuelling
may cause vapors to escape or even
cause fue l to spill out of the tank. This
would then shut off the fuel nozzle be­
fore the tank is full.
- Do not refuel your vehicle w ith the igni­
tion turned on. The fuel gauge may oth­
erwise not ind icate the correct fuel level
after refuell ing.
- Diesel veh icles* are equipped with a die­
sel misfueling protector. It allows the
vehicle to be fueled only w ith a diesel
fuel pump nozzle. A worn or damaged
nozzle or a nozzle that is too small may
not be able to open the diesel misfueling
protector. If this is the case, try turning
the nozz le before inserting it in the fue l
filler neck, use a different fuel pump or
see your authorized Audi dealer or au­
thorized repair facility for assistance.
Unlocking the fuel filler flap by hand
You con open the fuel filler flop by hand if the

Selective catalytic
reduction
General information
Applies to vehicles: with diesel engine
On vehicles with selective catalytic reduction,
an urea solution (AdBlue) is injected into the
exhaust system before a nitrogen oxide cata­
lytic converter to reduce nitrogen emissions.
The Ad Blue is stored in a separate tank in the
vehicle. The Ad Blue usage accounts for ap­ proximately 0.5% to 1.2% of the diesel fuel
