A WARNING ,~
- Do not park your vehicle over flammable
materials such as grass or leaves because
the high temperature of the diesel par­
t icu late filter cou ld start a fire .
- Do not apply an underbody protectant in the exhaust system area or a fire could start .
Shutting down vehicle
If you would like your veh icle to remain inop ­
erat ive for a longer period of time, contact an
Aud i or other specia lized dealer. They can ad­
vise you on necessary precautions e.g . corro­
sion prevention, ma intenance and storage.
Pay attention to additiona l information con­
cerning the battery. Refer to~
page 240.
Avoid damaging the
vehicle
When you a re driving on poor roads, or over
curbs, steep ramps, etc., make certain that low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam­
aged.
This is especially true for vehicles with low­
slung chassis (sports chassis)* and fully load ­
ed vehicles.
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads :
- The water must not be any higher than the
bottom of the veh icle body.
- Do not drive faster than wa lking speed.
A WARNING
After driving through water, mud, slush,
etc., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry

the brakes first by braking carefully to re­
store the full braking effect.
(D Note
- Vehicle components such as the engine,
transmission, suspension or electrical
system can be severely damaged by driv­
ing through water.
- Always switch off the Start-Stop-System*
when driving through water
~ page 87.
(D Tips
-Check the depth of the water before driv­
ing through it .
- Do not stop the vehicle, drive in reverse
or switch the engine off when driving
through water.
- Keep in mind that oncoming vehicles may create waves that raise the water
level and make it too deep for your vehi­
cle to drive through safely .
- Avoid driving through salt water because
it can cause corrosion.
Operate your vehicle
economically and minimize pollution
General
Your personal style of driving will determine
t he economy of your vehicle , as well as ex­
haus t and noise levels.
Fuel economy, environmental impact, and
wear on your engine, brakes and tires largely
depend on three factors:
- your personal driving style
- operating conditions
- technical limitations
If you ant icipate what you need to do next and
drive economically, you can easily cut your
fuel consumpt ion by 10-15 percent . This sec­
tion w ill give you some tips on how you can
help the env ironment and your pocketbook. •

The speed rating letter code (c::> page 248) is
on the side wall of the tire
c::> page 256.
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
imum speed . Always know the maximum
speed before driving off. Never drive faster
than the speed permitted for your specific
winter tires . This will cause damage to the
tires leading to an accident and serious
personal injury to you and your passen­
gers.
A WARNING
Driving faster than the maximum speed
for which the winter tires on your vehicle
were designed can cause tire failure in­ cluding a blowout and sudden deflation,
loss of control, crashes and serious per­
sonal injuries . Have worn or damaged tires
replaced immediately.
- Winter tires have maximum speed rating
that may be lower than your vehicle's
maximum speed .
- Never drive faster than the speed for
which the winter or other tires installed
on your vehicle are rated .
A WARNING
Always adjust your driving to the road and
traffic conditions. Never let the good ac­
celeration of the winter tires and all-wheel
drive tempt you into taking extra risks . Al­
ways remember :
- When braking, an all-wheel drive vehicle
handles in the same way as a front drive
vehicle.
- Drive carefully and reduce your speed on
icy and slippery roads, even winter tires
cannot help under black ice conditions.
@l For the sake of the environment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.
-
Tires and wheels
Snow chains
Snow chains may be fitted only to the front
wheels , and only to certain tire sizes. Ask your
authorized Audi dealer on which tire sizes
snow chains can be used.
If you are going to use snow chains, then you
must install them on the front wheels at
least.
The snow chains must have low-profile links
and must not be thicker than 0.4 inch
(10,S mm) , including the lock.
Remove wheel center covers and trim discs
before putting snow chains on your vehicle
c::> (]) . For safety reasons cover caps must then
be fitted over the wheel bolts. These are avail­
able from authorized Audi dealers.
A WARNING ,..__
Using the wrong snow chains for your vehi­
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different
sizes . Always make sure to follow the in­
structions provided by the snow chain manufacturer .
- When driving with snow chains never
drive faster than the speed permitted for
your specific snow chains .
- Always observe local regulations.
(D Note
- Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into direct con­
tact with the wheel rim, can scratch or
damage it. Therefore, make sure that the
snow chains are suitably covered . Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow chain manufacturer when doing so.
- If the Adaptive Air Suspension should
malfunction, do not mount or use snow ..,.

@ Tips
Check carefully to make sure the hook-up
is secure before moving the car up the flat­
bed truck ramp.
Vehicle transport
Whenever you hove your vehicle transported,
be sure to note the following:
(D Note
Mount the tie-down chains/cables over the
running surface (circumference) of the
tires. Never secure the vehicle by the axle,
the suspension struts or the front or rear
towline eye. For technical reasons, the
pressure in the suspension struts may
change du ring the transport and this will
adve rsely affect vehicle handling.
Lifting vehicle
Lifting with workshop hoist and with
floor jack
The vehicle may only be li~ed at the lifting
points illustrated.

• Locate lifting points Q fig. 242 and
¢fig. 243.
• Adjust lifting arms of wo rkshop hoist o r
floor jack to match veh icle lifting points.
• Insert a rubber pad be tween the floo r jack/
workshop hoist and the lift ing po ints .
The vehicle jack mode must be activated so
that the automat ic adjustment of the Adap­
tive Ai r Suspens ion does not make it more dif­
fic ult to raise the vehicle with the floor ja ck.
If you mu st l ift your vehicle with a fl oor jack

s af ely s upported on stand s intended for thi s
purpose.
Front lifting point
The lifting point is located on the floor pan re­
i nforcement about at the same leve l as the
jac k mounting point
Q fig . 242. Do not lift
t h e v ehi cle at the verti cal sill reinf orcement .
Rear lifting point
The lifting point is located o n the vert ical rein ­
forcement of the lower sill for the on-board

Lifting with vehicle jack
Refer to ¢ page 2 72 .
&_ WARNING ,-~
-To reduce the risk of serious injury and
vehicle damage .
- Always lift the vehicle only at the spe­
c ia l workshop ho ist and floor jack lift
points illustrated
¢fig . 242 and
¢ fig. 243 .
- Fail ure to lift the vehicle at these
po ints co uld cause the vehicle to tilt or
fall from a lift if there is a change in ve­
hicle weight distribution and balance.
This might happen, for example, when h eavy components such as the eng ine
block or transmission are removed.

Gross Ax le Weight R atin g
The Gross Axle Weight Rating is the maximum
l oad that can be applied at each axle of the
vehicle
c::> &. .
Vehicle capacity weight
The vehicle capac ity we ight (max. load) is list­
ed eithe r on the dr iver's side B-pillar or inside
the fuel filler flap.
A WARNING
- The actual Gross Axle Weight Rat ing at
the front and rear axles should not ex­
ceed the perm iss ible weights, and their
combination must not exceed the Gross
Vehicle Weight Rat ing.
Dimensions
I>
-
- Exceeding permissible weight ratings can
result in veh icle damage, acc idents and
personal injury.
(D Note
- The vehicle capacity weight figures apply
when the load is distributed evenly in the
vehicle (passengers and luggage). When
transport ing a heavy load in the luggage
compartment, carry the load as near to
the rear axle as poss ible so that the vehi­
cle's handling is not impaired.
- Do not exceed the maximum permissible
axle loads or the maximum gross veh icle
we ight. Always remember that the vehi­
cle's handling w il l be affected by the ex­
tra load. Therefo re, adj ust your speed ac­
cordingly.
- Always observe local regulat ions.
