Chassis controls
Fi ve differen t driving modes can be set by the driver.
The automatic contro l processes are speed -and time -dependent.
For example, it is not possible to raise the suspension to a high level
above certain speeds.
When a speed of about 75 mph (120 km/hl is exceeded for more than 30 seconds, the vehicle is automatically lowered to
low level when
in com fort and automatic mode . Ground clearance is about 0 .6 inch
(15 mm) less, compared to the
normal level.
When a speed of about 100 mph (160 km/h) is exceeded for more
than 20 seconds, the vehicle is automatically lowered to
highway
/eve/when in automatic and dynamic mode. Ground clearance is
about 1.4 inches (35 mm) less, compared to the
normal level. Road
holding is optimized as a resu lt of the lower center of gravity, and
fue l consumpt ion is reduced as a result of reduced wind resistance .

Aut omatic l ower ing :
When a speed of about 75 mph (120 km/h)
is exceeded for more than 30 seconds, the vehicle is automatica lly
lowered by about 0 .6 inch (15 mm) to the
low level, which is more
suitable for highway speeds . Road holding is opt im ized as a result
of the lower center of gravity and fuel consumption is reduced as a
result of reduced wind resistance. When a speed of about 100 mph
(160 km/h) is exceeded for more than 20 seconds, the vehicle is
automatically lowered by an additional 0 .8 inch (20 mm) to
highway
level.
• Automatic rai sing: When the vehicle is at highway level and the
speed fa lls be low about 80 mph (130 km/h) for more than 20
seconds, the vehic le is automatica lly raised to
low level. The vehicle
is automatically raised again to
normal level if the speed fa lls be low
about 44 mph (70 km/h) for a period of 2 minutes. The vehicle is
ra ised immediate ly when speed fa lls below about 22 mph (35 km/h).
dynamic
Select the dynamic mode if you prefer a sporty suspension sett ing.
I n this mode, the vehic le is lowered to
/ow level while it is sti ll
stationary and sporty damping characteristics are selected . The
warning light~ in the instrument cluster will come on for a few
seconds jus t to remi nd you of the reduced ground clearance .
I f you switch off the engine while the vehicle is in the dynamic mode
and then switch on the ignition once again, the~ warning light
wi ll also come on again for a few seconds as a reminder.
• Automatic lowering : When a speed of about 100 mph (160 km/h)
is exceeded for more than 20 seconds, the ve hicle is auto matica lly
lowered by 0.8 inch (20 mm) to
highway level.
• Automatic rai sing: The vehic le is automatically raised to low level
again, if the speed falls below about 80 mph (130 km/h) for a period
o f 20 secon ds. The ve hicle is ra ised i mmediately whe n speed falls
below about 22 mph (35 km/h). .,_

comfort
Select the comfort mode if you desire a suspension setting with a
special emphasis on comfort . Damping characteristics with a clear
emphasis on comfort are selected in this mode .
• Automatic lowering: When a speed of about 75 mph (120 km/h)
is exceeded for more than 30 seconds , the vehicle is automatically
lowered by 0.6 inch (15 mm) to /ow level.
• Automatic raising: The vehicle is automatically raised to normal
level again, if the speed falls below about 44 mph (70 km/h) for a
period of 2 minutes . The vehicl e is raised immediately when speed
falls below about 22 mph (35 km/h).
offroad
Select the offroad mode when you have to travel over poor quality
sections of road (e.g . trails). In this mode, th e vehicle is rais ed to
high level 1, and damping characteristics for poor road stretches are
selected. When switching to offroad mode, th e Adaptive Air Suspen ­
sion indicator appears automatically in the instrument cluster
display => page 209 .
• Automatic lowering: When a speed of about 62 mph (100 km/h)
is exceeded , the vehicle is lowered by 1 inch (25 mm) to normal level.
• Automatic raising: The vehicle is ra ised to high level 1 again
when the speed falls below about 43 mph (70 km/h).
lift
Select the lift mode when exceptionally high ground clearance is
needed at a reduced speed. In this mode, the vehicle is raised to
high level 2 . When switching to lift mode, the Adaptive Air Suspen­
sion indicator appears automatically in the instrument cluster
display=> page 209.
The lift mode can be activated only a t spe eds b elow 12 mph (20
km/h). When a speed of about 25 mph (40 km/h) is exceeded, the
system automatically leaves lift mode and the offroad mode is acti­
vated. The instrument cluster display automatically switches the
display to Adaptive Air Suspension to indicate reduced ground
clearance.
[ i] Tips
Please note that driving at high speeds on paved roads while in
offroad mode for extended periods of time leads to increased tire
wear. •

• For any work on the airbag system , we strongly recommend
that you see your author ized Audi dealer or qual ified workshop .
• Never modify the front bumper or parts of the vehicle body.
• Always make sure that the side airbag can inflate without inter ­
ference :
- Never install seat covers or replacement upholstery over the
front seatba cks that have not been spe cific ally approved by
Audi.
- Never use additional seat cushions that cover the areas
where the side airbags inflate.
- Damage to the original seat covers or to the seam in the area
of the side airbag module must always be repaired immedi­
ately by an authorized Audi dealer .
• The airbag system can be activated only once. Afte r an airbag
has inflated , it must be replaced by an authorized Audi dealer or
qualified technician who has the te chnical information , training
and spe cial equipment necessary.
• The airbag sy stem can be deployed only once. After an airbag
has been deployed , it must be repla ced with new repla cement
parts designed and approved especially for your Audi model
version . Replacement of complete airbag systems or airbag
components must be performed by qualified workshops only .
Make sure that any airbag service action is entered in your Audi

Other things that can affect Advanced Airbag
performance
Changing the veh ic le 's su spension system can change the way that
th e Advanced Air bag Syste m performs in a c rash. Fo r example,
using tire-rim combinations not approved by Audi, lowering the
v eh ic le, c hang ing the stif fness of th e suspe nsio n, in cl ud in g the
springs, suspension struts, shoc k absorbers etc . can change the
fo rces that a re m eas ure d b y the air bag senso rs and se nt to the elec ­
tronic control unit. Some suspension changes can, for example,
increa se the fo rce level s measured by the sen so rs and ma ke the
a irbag syste m dep loy in crash es in which it wou ld not dep loy if the
changes ha d not been made . Othe r kinds of change s may red uce
t he fo rce lev els measu red by the se nso rs a nd preve nt the airba g
from deploying when it should.
T he sens ors i n th e safe ty bel t buc kle for th e driver a nd fr ont
passenger seat tell the electronic control modu le if the safety belt is
l a tc h ed or not. I f th e safe ty belt is being used, the fron t airbag wi ll
deploy at a slight ly h igher rate of vehic le dece leration than if the
sa fe ty be lt is n ot b ein g use d. Therefore, i n a partic ular c ollisi on, it i s -.,

possible that an airbag will not deploy at a seating position where
the safety belt is being used but will inflate at the position where the
safety belt is not being used . It is important that nothing interfere
with the safety belt buckles so that the sensors can send the correct
information about safety belt use to the electronic control unit .
& WARNING
Changing the vehicle's suspension including use of unapproved
tire -rim combinations can change Advanced Airbag performance
and increase the risk of serious personal injury in a crash.
• Never install suspension components that do not have the
same performance characteristics as the components originally
installed on your vehicle.
• Never use tire-rim combinations that have not been approved
by Audi.
& WARNING
Items stored between the safety belt buckle and the center
console can cause the sensors in the buckle to send the wrong
information to the electronic control module and prevent the
Advanced Airbag System from working properly.
• Always make sure that nothing can interfere with the safety
belt buckles and that they are not obstructed.
Undeployed airbag modu les and pretensioners might be classified
as Perchlorate Material -special handling may apply, see
www.dtsc .ca.gov/ha zardouswaste/perchlorat e. When the vehicle or
parts of the restraint system including airbag modules and safety
belts with pretensioners are scrapped, all applicable laws and regu­
lations must be observed. Your authorized Audi dealer is familiar
with these requiremen ts and we recommend that you have your
dealer perform this service for you.•

Side airbags
Description of side airbags Airbag
system
The airbag system
can provide supplemental protection
to properly restrained occupants.
Fig . 254 Side airbag
location in the driver's
sea t
The side airbags are located in the sides of the front seat backrests
~ fig. 254 and the rear backrest * facing the doors . They are identi ­
fied by the word "AIRBAG" .
The side airbag system basically consists of:
• the electronic control module and external side i mpact sensors
• the two side airbags located in the sides of the front backrests
• two rear side airbags (as an ordered
option)
• the airbag warning light in the instrument cluster.
The airbag system is mon itored e lectronica lly to make certain that
it is functioning prop erly at all times. Each time you turn on the igni ­
tion, the airbag system indicator light will come on for a few
seconds (se lf diagnostics) .
The side airbag system supplements the safety belts and can help
to reduce the risk of injury to the driver's , front and rea r*
passenger's upper torso on the side of the vehicle that is struck in a
s ide collision . The airbag dep loys on ly in side impacts and only
when the vehicle acceleration registered by the control unit is high

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. •
