The c.:, symbol illuminates for a few seconds after you have
switched on the ignition to indicate
r e du ced ground cle aranc e when
the dynamic mode is activated and when the ignition is switched on
with a vehicle which was parked in dynamic mode=>
page 189,
"Chassis Controls" . On vehicles which are equipped with the s por t
s u sp en sio n
Adaptive Air Suspension -Sport*, the check light does
not come on in this instance since ground clearance is general ly
reduced.
This warning/indicator light has the following functions: • It illuminates for a few seconds after the ignition is turned on as
function check and then goes out.
• If the warning/indicator light flashes in conjunction with the
~
warning/indicator light, you should not drive the vehicle immedi­
ate ly in order to prevent damage to the underbody. The two
warning/indicator lights flashing together points to an extreme Low level. A very
pronounced lowering of the vehicle (extreme Low level)
can result, for example, from a heavy load. As soon as the level has
returned to normal, the warning/ind icator lights stop flashing , and
you can drive away .

Vehicles moving in you r direction can be detected up to a dis tance
of about 140 yards (130 meters) bu t the Adaptive Cruise Control
cannot detect vehicles that are stopped or sta lled, obs tacles that do
not move or narrow vehic les like motorcyc les and bicycles .
Open road
When the road is c lear, Adap tive Cruise Con trol works like cruise
control. It maintains a constant target speed specified by the driver .
Driving in traffic
If a slow er vehicle driving ahead is detected, the Adaptive Cruis e
Contr ol dece lerates (within the limits of the system) ::::,
page 150 to
its spe ed and after adjusting, tries to maintain the set distance from
t he veh ic le ahead. The vehicle may temporar ily d rive slower tha n
the set speed while adjusting ::::,
& in "Description" on page 139.
If the vehicle in front accele rates, Adaptive Cruise Control also accel ­
erates up to the speed that you have set.
Situations requiring driver intervention
I n some situations you w ill have to use the foot brake and slow the
veh icle down in order to keep a sa fe distance from vehicle in front
of you or to avoid a rear -end collision. In this situation, a symbol
appears and a warning tone sounds::::,
page 146.
Passing another vehicle
If you move int o the pa ssing lane and no vehicle is detecte d ahead,
Adaptive Cruise Contro l accelerates to the speed you have set and
maintains it .
Overriding ACC
You can increase your speed a t any time by stepping on the acceler ­
ator pedal. After you re lease the accelerator pedal, the system
adjusts back down to the speed you previously set .
Contro ls and eq uip­
ment
& WARNING
• Never rely on the distan ce control feature of ACC alone to
prevent rear -end collisions. Always be prepared to brake and take
evasive action to avoid colli sio ns and other accident situation s.
• Never allow the closing speed between you and other vehicle s
to be so high that the Adaptive Cruise Control may not be able to
slow your vehicle safely . If clo sing speed i s too high , you must
apply the brakes yourself to reduce the risk of a rear -end cra sh .
[ i ] Tips
Please note that the amount of acceleration the Adaptive Cruise
C o ntro l use s depends on the Distance setting selected . DISTA NCE 1
gives you acceleratio n that is dynamic a nd sporty. D IS TA NCE 4, on
the other hand, gives more moderate acceleration . For more infor ­

Adaptive Air Suspension
Adaptive Air Suspension and
Damping
Description
Adaptive Air Suspension and damping can be regulated and they adapt automatically t o a request from the driver
and the driving situation at the time.
Adaptive Air Suspension is an electronica lly controlled springing
and damping system. This chassis system makes it easier on the
driver by adapting to the particular situation through imperceptible
control processes.
The
Ad aptiv e Ai r Suspen sion component regulates ground clear ­
ance depending on vehic le speed, load condition and driver input.
Accelerating to a speed above a predetermined limit wil l make the
vehic le lower itself. On the other hand, driving more slowly results
in the vehicle raising aga in at specific speeds.
The
damping component provides individual control of the
damping forces . For example, with damping c haracteristics set to
provide greater comfort, damping is set somewhat harder for a brief period only as required, for example, when going around a curve or
over rough road surfaces as well as when braking.
Settings
Adaptive Air Suspension provides the driver w ith the opportunity to
set the chassis characteristics also to their individual preference .
With the driving modes
standard, automatic and dynamic the driver
has three chassis settings available, ranging from comfort to sporty.
In addition,
lift provides a fourth mode which can be selecting for
driving over poor stretches of road=>
page 189, "Chassis Controls".
The modes are set in MMI =>
page 191.
On vehicles equipped with the s port su spen sio n Adaptive Air
Suspension -Sport*, there is generally more emphasis on a sporty
chassis setting. Settings range from comfortable to firm
=>
page 190, "Sport Chassis Contro ls".
0 Note
• Whenever you park your vehicle, always make sure there is
adequate c learance
above and below the vehic le . The height of the
parked vehicle can change as the result of temperature fluctuations,
changes in load conditi on and changes in the driving m ode (gro und
clearance).
• Mount the tie -down chains/cables over the running surface
(circumference) of the tires . Never secure the vehicle by the axle, the
suspension stru ts or the front or rear towline eye. For technical
reasons, the pressure in the suspension struts may change during
the transport and this wi ll adversely affect vehicle handling.
• To prevent damage to the vehicle underbody, remember that
you r veh ic le is not an off -road vehicle, even in the lift mode. The
ground c learance is insufficient for this type of operation.
• If you are going to tow a trai ler, you must activa te the trai ler oper ­
ation mode=>
page 792.
[ i ] T ip s
Before you can raise your vehic le using the vehicle jack (for
example, when changing a flat tire) you must activate the jacking
mode=>
page 191 . •

Chassis Controls
Four different driving modes can be set by the driver.
The automatic control processes are speed -and time -dependent.
For example, it is not possib le to raise the suspension to the lift
mode above certain speeds .
When a speed of about 75 mph ( 120 km/h) is exceeded for more than
30 seconds, the vehicle is automatically lowered approximately 1
inch (25 mm) to a level suitable for highway speeds, except in the
standard mode . Road holding is optim ized as a result of the lower
center of gravity and fue l consumption is reduced as a result of
reduced wind resistance .

(The term "ISOFIX" regarding lower anchorages had been used by
Audi and other manufacturers in the past, but LATCH is now the
standard name for the new child restraint anchorage system.)
Some child restraint system manufacturers have been providing
tether straps on certain models of their child restraint systems, either as standard equipment or as a retrofit, for several years .
Check with the manufacturer of the child restraint system for tether
strap availability .
To provide a simpler and more practicable way to attach the child
restraint system on the vehicle seat, U.S. Federal regulations require
the phase -in of lower anchorages in vehicles and devices on new
child restraint systems to attach to the vehicle anchorages.
Child restraint system manufacturers will probably offer two kinds
of lower anchorages on their child safety seats
They could come with:
• hooks or other latches attached to adjustable straps or
• rigid latches on bars that extend out the back of the child
restraint and are released with release buttons at the bottom of the
child restraint.
In addition to the LATCH lower anchorages, both of these child
restraint systems use tether straps to help keep the child restraint
system firmly in place .•
Where can I get additional information about
child restraint application and usage?
There are a number of sources of additional information about child
restraint selection, installation and usage :
NHTSA advises that the best child safety seat is the one that fits
your child and fits in your vehicle, and that you will use correctly and
consistently.

- Lack of proper maintenance as wel l as improper use of the
vehic le wi ll impair the func tion of the emission con tro l system
and could lead to damage.
<£> For the sake of th e envir onm ent
Even when the Emission Control System is operating properly, the
exhaust gas can have a su lfur -like exhaust gas smell under some
operating states . This depends on the sulfur content of the fuel
being used. Using a different brand of fue l may help, or filling the
tank with lead-free super grade gasoline. •
Avoid damaging the vehicle
When you are driving on poor roads, or over curbs, steep ramps,
etc., make certain that low- lying parts such as spoi lers and exhaust
system parts do not bottom out and get damaged.
This is especially true for vehicles with low-slung chassis (sports
chassis) * and fully loaded vehicles .

Operate your vehicle economically
and minimize pollution
General
Your personal style of driving will determine the economy
of your vehicle, as well as exhaust 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 cond itions
• technica l limitations

If you anticipate what you need to do next and drive economica lly,
you can easily cut your fuel consumption by 10 -15 percent . This
section wil l give you some tips on how you can help the environ­
ment and your pocketbook.
[ i ] Tips
The consumption estimates as published by ENV IRONMENTAL
PRO TEC TION AGENCY (EPA) and Transport Canada may not corre ­
spond to your actua l consumption on the road, which wi ll vary
depending upon vehic le load and speed, road and weather condi­

Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they ore accelerating.
-Avoid unnecessary accelerat ing and braking.
Vehicles use the most fuel when they are accelerating . If you antici­
pate what is going to happen next, you wi ll need to brake less and,
thus, acce lerate less. Let the vehicle coast whenever possib le - for
examp le when you see that the next traffic light is red. •
Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
-Try and keep well below your car 's max imum speed.
Acce lerating gently reduces fue l consumption , engine wear, and
does not disturb the environment.
Fue l consumption, exhaust emissions and engine noise increase
disproportionately at high speeds . If you drive at approximate ly
three quarters of top speed, fuel consumption wil l be reduced by
