Applies to: vehicles with diesel engine and diesel particulate
filter
II Particul ate filt er: malfunct ion! See own er' s
m anual
The diesel particulate f ilter requires regenera­
tion. To support the filter's self-cleaning func­
tion :
Drive for approximate ly 15 minutes at 37 mph
(60 km/h) or above in the S se lector lever posi­
tion. Keep the eng ine speed around 2,000 RPM.
The temperature increase that will result from
this can burn off the soot in the filter . The ind ica ­
tor light will turn off when the cleaning has com­
p leted successf ully.
H ave an authorized Audi dealer or authorized
Aud i Serv ice Facility repa ir the malfunction im ­
mediately if the ind icator light does
not turn off .
A WARNING
Always adapt your speed to the cu rrent
weather, road and traffic conditions . You
should never disobey traffic laws in order to
follow driving recommendations .

f Engine warm-up request
n Please warm up engine
Fuel has entered the engine oil, eithe r from low
outside temperatures or frequent short drives.
Drive until the eng ine is warm so that the fuel in
the engine o il w ill evaporate. Avoid high engine
speeds, full accelerating and heavy engine loads
when doing this .
E@ Tank system
liD Please refuel
If the indicator light turns on for the first time
and the message appears, there are about 2.1
gallons (8 liters) of fuel left in the tank .
(iD Please refuel immediately
If the indic ator ligh t turns on the message ap ­
pears, the fuel tank is a lmost empty. Refue l the
vehicle immediately .

Driving
next traffic light is red . This produces an engine
braking effect, which helps to protect the brakes
and tires and reduces the emissions and fue l con ­
sumpt ion to zero (fuel shut-off during decelera­
t ion).
Shift effici ently
An effective way to save fuel is to upshift earlier.
Staying in a gear too long uses fue l unnecessari ­
ly .
P ress down o n the acce lerator peda l slowly and
avoid "kick -down".
Avoid full acceleration
You shou ld rare ly t rave l at the maximum vehicle
speed. High speeds cause a disp roportiona tely
h igh inc rease in fuel consump tion, emissions and
traffic no ise . Slower driving saves fuel.
Reduce idling time
The Start/Stop system* he lps to reduce the idling
time automatically. In vehicles witho ut the Start/
S top system* , it is efficient to swit ch the eng ine
off when stopped at r,;1ilro,;1d crossi ngs and long
red lights . Stopping the engine for 30 -40 sec ­
onds already saves more fuel than the amount of
extra fuel needed to restart the engine.
It t akes a very long time in idle to war m the en ­
g ine up to opera ting tempera ture . Wea r and
emissions are especially high in the warm -up
p hase . Therefore, yo u should begin driving im ­
mediately after starting the engine. Avoid high
RPMs while do ing th is.
Have maintenance performed regularly
By having ma intenance performed regularly on
your vehicle, you can help to reduce f uel con­
sumpt ion befo re yo u even start to dr ive. The
maintenance condition of your vehicle not only
affects t raffic safety and long-term value but a l­
so impacts
fuel consumpt ion . A poorly main ­
tained engine can lead to f uel consumption that
is 10% higher than normal.
Avoid short trips
The engine and exhaust cleaning system m ust
reach the ir opt imal
operating temperature to ef­
fectively reduce consumption and em iss ions.
74
A cold engine uses a d isproportionately high
amount of fue l. The engine reaches operating
temperat ure and cons umption norma lizes on ly
after approximate ly
four ki lometers.
Check the tire pres sure
To save fue l, make sure the t ires are always in­
flated to the correct press ure
¢ page 32 7. The
fuel consumpt ion can increase by S% if the pres ­
s u re is only 0.5 bar too low. Due to the increased
roll ing resistance, low tire pressures w ill also
l ead to greater tire
wear and will affect dr iving
behavior.
Do not drive on
winter tires year-round, as this
will consume up to 10% more f uel.
Eliminate unnecessary we ight
Since eve ry kil og ram o f extra weight in creases
fuel consumption, a quick inspection of the lug­
gage compartment may be worth it to avoid un­
necessary we ight.
When no t be ing used, a roof rack sho uld be re ­
moved to decrease the wind resistance of the ve­
hicle . You will save approx imately
12% of your
fuel when at speeds from 62-75 mph (100-120 km/h).
Save energy
The eng ine drives the generator, which generates
electricity; the fuel consumption also inc reases
with the demand for e lectricity. Therefore, switch
e lectrical equ ipment off when you no longer
need it. Examples of eq uipment that uses a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating* .
(D Note
Do not leave engine idling unattended after
starting . If warning lights shou ld come on to
i ndica te improper operation, they would go
unheeded . Extended idling also prod uces
h eat, w hic h could result i n overheating o r
o ther damage to the veh icle o r othe r prope r­
ty .

slow your vehicle down as if you had made a
full braking maneuver. ESC and the associat ­
ed components (ABS, ASR, EDL) cannot over­
come the laws of physics . In corners and
when road or weather conditions are bad , a
full brake application can cause the vehicle to skid or the rear end to swerve, which increas­
es the risk of an accident.
Hill hold assist
Hill hold assist makes it easier to start on hills .
The system is activated when the brake pedal is pressed for a
few seco nds. The vehicle must be in
an uphill direction of travel.
After releasing the brake pedal , the brake power
is held for a
brief moment to prevent the vehicle
from rolling back when starting. During this
time , you can easily begin to
move your vehicle.
& WARNING
- If you did not begin moving immediately af­
ter releasing the brake pedal, the vehicle
could begin to roll backward under certain
conditions . Press the brake pedal or set the
parking brake immediately .
-If the engine stalls, press the brake pedal or
set the parking brake immediately.
- To prevent the vehicle from rolling back un­
intentionally when starting in stop-and-go
traffic, keep the brake pedal pressed for a
few seconds before you start driving.
- Switch the ignition off when you leave the
vehicle, even for a short period of time. Also
set the
parking brake to prevent the vehicle
from rolling unintentionally . This applies
particularly when children remain in the
ve­
hicle, because there is the risk of an acci­
dent .
Automatic transmission
Introduction
The automati c transmission is controlled elec ­
tronically . The transmission shifts up or down au­
tomatically depending on which drive program is
selected .
Driving
When a moderate driving style is used, the
transmission selects the most economical driving
mode. The transmission shifts up at a lower RPM
and shifts down at a higher RPM to improve fuel
efficiency.
The transmission switches to a sporty mode after
a kick-down or when the driver uses a
sporty
driving style
characteri zed by quick accelerator
pedal movements, heavy acceleration, frequent
changes in speed and t raveling at the maximum
speed .
If desired, the driver can also select the gears
manually (tiptronic mode) ¢ page 86.
Selecting selector lever positions
Fig. 83 Selecto r lever
The current selector l ev e r pos ition is shown next
to the selector lever¢
fig. 83 . The current selec­
tor lever position is also shown in the instrument
cluster d isplay .
.,. You may need to release the selector lever lock
depending on which selector lever position is
selected and which one you would like to se­
lect .
.,. To do this, press the locking button (Don the
selector lever¢
fig. 83.
.,. To engage the nearest se lector lever position,
move the selector lever forward/back until you
feel the first pressure point. The selector lever
will return to its original position.
.,. To skip
over one selector lever position, move
the selecto r lever past the pressure point into
the desired position . The selector lever will re­
turn to its original position.
For example, you can skip
over the N position if
you would like to go directly from D into R. ..,.

Wheels
-The tire must flex more if the tire pressure is too low or if
the vehicle speed or load are
too high . This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­
trol.
-Incorrect tire pressure in­ creases tire wear and has a
negative effect on driving and
braking behavior, which in­
creases the risk of an accident.
(D Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.
Tire pressure table
Please note that the information
contained in the following table
was correct at the time of print­
ing, and the information is sub­
ject to change. If there are differ­
ences between this information
and the tire pressures specified
on the label on the driver's side 8-pillar, always follow the specifica­
tion on the 8-pillar label
¢ page 327, fig. 255.
328
(i} For the sake of the environment
-Tire pressure that is too low
increases fuel consumption.
-Fuel consumption may also in­
crease when driving with the
comfort tire pressure is se­
lected .
(D Tips
Audi recommends using the
tire pressure specified for a
normal load
¢ table on
page 329
or for a full load
when the vehicle is partially loaded.
Make sure that the tire designa­
tion on your tire matches the des­ ignation on the tire pressure label
and the tire pressure table.

Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop. Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden

and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas­
sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­ cle's
Gross Vehicle Weight Rat­
ing
("GVWR").
The "GVWR" includes the weight of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids ..

bolts and a special procedure. You must never
repair or disassemble them ¢
.&..
A WARNING
Wheel bolts that are tightened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct t ightening specifi ­
cation, refer to ¢
page 348, Finishing .
-Always keep the wheel bolts and the
threads in the wheel hub clean and free of
grease .
- Only use wheel bolts that fit the rim .
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility . Never repair or disassemble
rims yourself, because this increases the risk
of an accident.
Winter tires
W inter tires significantly improve the vehicle's
handling when driving in winter conditions. Be­
cause of their construction (width, compound,
tread pattern) , summer tires provide less trac­
tion on ice and snow.
.,. Use winter t ires on all four wheels.
.,. Only use winter tires that are approved for your
vehicle.
.,. Please note that the maximum permitted
speed may be lowe r with winter tires
q ,&. . An
authori zed Audi dealer or authori zed Audi Serv­
ice Facility can inform you about the maximum
permitted speed for your tires .
.,. Check the tire pressure after installing wheels
¢page 327.
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0 .16 in (4 mm) . The characteristics of winter
tires also decrease great ly as the tire ages, re­
gardless of the remaining tread .
A WARNING
-Never drive faster than the maximum per­
mitted speed for your tires. This could cause
the tires to heat up too much. This increases
332
-
the risk of an accident because it can cause
the tire to burst.
- Always adapt your driving to the road and
traffic conditions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter tires can lose traction on black ice .
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they prov ide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumpt ion .
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun­
tries where winter tires are required, only
winter tires w ith the ~ symbol are permitted .
Snow chains
Snow cha ins not only improve the driving in win­
ter road condit ions, but also the braking.
.,. Only install snow chains on the
front wheels .
This applies a lso to vehicles with all wheel
drive* .
.,. Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol­
low the instructions from the manufacturer.
.,. Note the maximum permitted speed when driv­
ing with snow chains. Do not exceed 30 mph
(SO km/h) .
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi deale r or author­
ized Audi Service Facility to see if you may use
snow chains .
Use
fine-mesh snow chains. They must not add
more than 0.53 in (13 .5 mm) in height, including
the chain lock.
You must remove the snow chains on roads with­
out snow. Otherwise , you could impair driving
ability and damage the tires .
