Driving tips
On poor road and off road, there is always only one motto:
Plan ahead and drive slowly!
Please observe the following when driving away from paved
roads:
Vehicle care Do-it-yourself service Technical data

lffll __ D_ r_ iv _i_ n-' g"'""'- o_ ff_ r_ o _ a_ d __________________________________________________ _
-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 into consideration the
ground clearance of your
vehicle.
- Activate the
ESP offroad mode=:> page 288 as needed.
- Use t he
hill descent control=:> page 289 when driving
down steep sections on hills.
Unpaved roads and offroad
Drive slowly on unfamiliar roads and unknown offroad sections, and
look out for unexpected obstac les (e.g . potholes, rocks, tree stumps,
etc.).
To prevent the vehicle from bottoming and avoid damage to the
underbody, you should drive straight across severe bumps in the
ground with on ly one side of the vehicle so that on ly two of your
whee ls cross the bumps .
Dr ive briskly through sandy or marshy offroad sections and do not
stop, if at all possible.
Driving through water
Your vehicle can drive through standing water if the ground is firm
enough . The
maximum fording depth is 19 .7 in or 500 mm (vehic les
without air springs) or 21.1 in or 535 mm (vehicles with adaptive air
suspension*, at high level 2).
Check the depth of the water before driving through water .
Cross water only at walking speed, do not stop and do not turn the
engine off .
If you drive fast through the water, you wi ll create a bow wave in
front of the vehic le. This bow wave can get into the engine air intake
and severe ly damage the engine. Avoid driving through salt water (corrosion)
.
Driving on a slope
If you ever find yourself not able to climb a slope, do not try to turn
around, drive back down in
reverse. Otherwise, you run the risk of
tipping over.
If the vehicle threatens to tip over when driving across a slope, you
must immediately steer downhill in the direction of the slope.
Do not park your vehicle on steep slopes or grades.
To reduce the risk of tipping over, drive on slopes in the direction of
the downward slope (fall line) -
not crosswise .
Driving on snow-covered ground
The standard tires fitted to your vehicle are not snow tires. So you
should mount wheels with snow tires in good time where winter
road conditions prevail. Before driving on unploughed stretches of
deep snow, install tire chains. For technical reasons, tire chains may
only be installed on the rear whee ls -never on the front wheels .
L1}. WARNING
After driving through water, mud, slush, etc. the brakes may be
slow to take effect because of wet brake rotors and pads . The
brakes must first be carefully dried by braking so that full braking
effect is restored. •

Trailer towing
Driving with a trailer
Genera l information
Your Audi was designed primarily for passenger transpor­
ta tion.
If you plan to tow a trailer, please remember that the add itional load
wi ll affect durability, economy and performance.
Trai ler towing no t only places more s tress on the vehicle, it a lso ca lls
for more concentration from the driver.
F or this reaso n, always fol low the operating and driving instructions
prov ided and use common sense.
(D Note
If you are going to tow a tra iler, you must activate the trailer opera ­
tion mode =>
page 211, "Towing a trailer".
Technical requirements
Trailer hitch
Use a we ight-carry ing hitch conforming to the gross tra iler weig ht.
T he hitch must be suitable for your vehic le and trailer and must be
m ounted secure ly on the veh icle's chassis at a
technically sound
location. Use only a trailer hitch with a removable ball mount.
Always check with the trai ler hitch ma nufacturer to make sure that
you are using the correct hitch .
Do not use a bumper hitch.
The hitch must be instal led in such a way that it does not in terfere
with the impact-absorbing bumper system. No modifications shou ld be made to the vehicle exhaust and b rake systems . Fro m

aile r t owing
time to time, check that all hitch mounting bolts remain securely
fastened .
When you are not towing a trai ler, rem ove the t railer hi tch bal l
mount. This prevents the hitch from causing damage should your
vehicle be struck from behind =>
&.
Trailer bra kes
If your trai ler is equipped with a b raking system, check to be sure
that it conforms to all regulations.
The tra iler hydraul ic bra ke system must not be directly co nnecte d to
the veh icle's hydrau lic brake system=> &.
Safety chains
Always use safety chains between your vehicle and the trailer.
Trail er lights
Trai ler lights must meet a ll regulations. Be sure to check with your
au thorized Audi dea ler for correct wiring, switches, an d relays.
Mirrors
If you are unab le to see the traff ic behind you using the regular
outside mirrors, then you
must instal l extended mirrors. It is impor ­
t ant that you
always have clear v isi on to the rear.
& WARNING
• If a trailer has electrical brake s please note that the se brakes
are not act ivated by the fa ctory-fitted control unit -ris k of acci­
dent!
• After removing the trailer hitch , do not store it in your vehicle.
In case of sudden braking , the hitch could fly forward and injure
you or your passengers .

from shifting forward, backward or sideways.
Never allow a passenger to ride in a trailer=> & in "D riving ins truc­
tions" on page 307.
Ball mount
T he trai ler hitch may only be used with suitab le ball mount and ball
=> fig. 276 . In sta llati on of t he hitch ball must be ca rr ie d o ut i n a ccor ­
dance with the manufacturer's instructions. At the height dimen­
s io n of 1 .5 in (38 .5 mm) a tole ran ce o f+/- 0 .5 in (12 .7 mm) is pe rmis ­
sib le.
Engine cooling system
T owing a trai ler makes the engine work harder. It is important that
th e c ooli ng system 's per forman ce is u p to the a ddi tiona l loa d. Ma ke
sure that the coo ling s ystem has enough f luid.
Tire pressure
When towing a trailer, inflate the tires of your vehic le to the cold tire
p re ssure l is ted unde r "Full load" on th e tire press ure l abe l. On USA
vehic les, the tire pressure label is located on the driver's side 8 -

pillar. On Canada vehicles, the tire pressure label is located either on
t he driver's side 8 -pillar or inside the fuel fil ler flap. Inflate trailer
tires to trailer and tire manufacturers' specifications.
L ight s
The head light settings should be checked with the trailer attached
before driving off . Check to make sure both vehicle and trai ler lights
are working properly.
Sa fety c hain s
Be sure trailer safety chains are properly connected from the trailer
to the hitch on the vehicle . Leave enough slack in the chains to
permit turning corners. When you insta ll safety chains, make sure
they will not drag on the road when you are driving .
The chains should cross under the tra iler 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 vehicle and trailer,
please note the fo llow ing:
- Do not tow a loaded trailer when your car i tse lf is not
loaded .
- Be especia lly careful when passing other vehicles .
- Observe speed l imits.
- Do not drive at the maximum permiss ible speed .
Controls and equip­
ment Safety first Vehicle operation
Tr
aile r t owing
Always apply brakes early .
- Monitor the temperature gauge .
Weigh t dis tr ibution
Towing a loaded trailer wi th an empty car results in a highly
unstable dis tribution of weight . If this cannot be avoided , drive at
very low speeds only to avoid the risk of losing steering control.
A "balanced" rig is easier to operate and control. This means that
the tow vehicle should be loaded to the extent possible and permis ­
sib le, while keeping the trailer as light as possib le under the circum ­
stances . Whenever possible, transfer some cargo to the luggage
compartment of the tow vehicle whi le observing tongue load
requirements and vehicle loading considerations .
Speed
The higher th e speed, the more difficu lt it becomes for the driver to
control the rig . Do not drive at t he maximum pe rmissible speed.
Reduce your speed even more
if load, weather or wind conditions
a re unfavorable -particularly when going downhil l.
Reduce vehicle speed
i mmedi ate ly if the trailer shows the slightest
sign of swaying.
Do not tr y to s top the swaying by accelerating .
Observe speed limits . In some areas, speeds for vehicles towing
trailers are lower than for regular vehicles .
Always apply brakes early. When driving downhill, shift into a lower gear to use the engine braking effect to slow the vehicle. Use of the
brakes alone can cause them to overheat and fa il.
Coo lant t emperatu re
The coolant temperature gauge=> page 13 must be obse rved care ­
ful ly. If the need le moves close to the upper end of the sca le , reduce
speed immediately and/or turn off the air conditioner .
If the coolant temperature warning light in the instrument cluster
starts f lashing
- f- , pul l off the road, stop and let the engine idle for
about two minutes t o prevent heat build -up.

Trailer towing tips
Important to know
Your vehicle handles differently when towing a trailer because of
the additional weight and different weight distribution. Safety,
performance and economy will greatly depend on how carefully you
load your trailer and operate your rig.
Before you actually tow your trailer, practice turning, stopping and
backing up in an area away from traffic. Keep practicing until you
have become completely familiar with the way your vehicle -trailer
combination behaves and responds.
Backing up is difficult and requires practice. Backing up with a
trailer generally requires steering action opposite to that when
backing up your vehicle without a trailer.
Maintain a greater distance between your vehicle and the one in
front of you. You will need more room to stop. To compensate for
the trailer, you will need a larger than normal turning radius.
When passing, remember that you cannot accelerate as fast as you normally would because of the added load. Make sure you have
enough room to pass. After passing, allow plenty of room for your
trailer before changing lanes again.
Avoid jerky starts, sharp turns or rapid lane changes.
[ i] Tips
• Do not tow a trailer during the break-in period of your vehicle. • If you tow
a trailer, your Audi may require more frequent mainte­
nance due to the extra load~
page 401. •
Parking on a s1ope
Do not park on a slope with a trailer. If it cannot be
avoided , do so only after doing the following:
When parking:
-Apply the foot brake.
- Have someone place chocks under both the vehicle and
the trailer wheels.
- With chocks in place, slowly release the brakes until the
wheel chocks absorb the load.
- Turn the wheels towards the curb.
- Apply the parking brake.
- Move the selector lever to
P.
When restarting after parking:
- Apply the foot brake.
- Start the engine.
- Move the selector lever to
D.
-Release the parking brake and slowly pull out and away
from the wheel chocks.
- Stop and have someone retrieve the wheel chocks.
[ i] Tips
I f you move the selector lever of the automatic transmission to P
before applying the parking brake and before blocking the wheels, II-

you may have to use more force later to move the lever out of the P
position .•
