possible to raise the suspension to a h igh level
above certain speeds .
When a speed of about 75 mph (120 km/h) is
exceeded for more than 30 seconds, the vehi­
cle is automatically lowered to
low level when
in comfort 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 ve­
h icle is automat ica lly lowered to
highway lev­
el
when in automatic and dynamic mode.
Ground clearance is about 1.4 inches (35 mm)
less, compared to the
normal level. Road
hold ing is optimized as a result of the lower
center of gravity, and fuel consumption is re­
duced as a result of reduced wind resistance.
Level adjustment Ground clearance
high level 2 about 9.4 inches
(2 40 mm)

weight. However, note that your vehicle is lowered and ground clearance is reduced.
- If you have to drive under difficult road con­
ditions, you can select offroad or lift mode,
after hitching up the trailer or after adjust­
ing the tongue weight.
- If the vehicle is at
normal level, and you se­
lect offroad mode while traveling at speeds
higher than 22 mph (35 km/h), the vehicle
will not be raised. Offroad mode will appear as the active mode in the MMI Display.
- If the vehicle is in offroad mode at
high level

Programming the rolling code
App lies to vehicles: with Home link
Additionally, a rolling code programming for
the Homelink universal remo te control is re­
quired for some systems.
Identifying the rolling code
"'Press the previously programmed Homelink
button again and hold it down .
"' Look at the LE D @ ¢
page 161, fig. 191 . If
the LED blinks quickly, the features, such as
the garage door opener, are equipped wi th
the rolling code .
"'Program the rolling code as follows:
Activating the garage door opener motor
unit "'Locate the setting button on the garage
door opener motor unit . The exact location
and color of the button may vary depending
on the garage door opener manufacturer .
Homelink 163
"' Press the setting button on the garage door
opener motor unit (usually this will activate
a "setting light display" on the motor unit).
Now you will have about 30 seconds time to
perform the Homelink button programming
on the controls .
Programming on the controls
"'Press the Home link button that was already
programmed and hold for two seconds.
"'To end rolling code programming, press and
hold the Homelink button for two seconds
again.
"'The Homelink button may need to be press­
ed a third time to end the adjustment proce­
dure for some garage door openers .
After the controls have been programmed, the
garage door opener should recognize the HomeLink signal and operate when the Home­
Link button is pressed. Now you may program
the other buttons as needed.
@ Tips
- Programming the rolling code can be
performed quicker and more easily with
the help of a second person.
- If difficulties should arise when pro­
gramming the rolling code, consult the
operating instructions for the garage
door opener or other devices for possible
solutions.

s trongly recommend that children always sit
in the back seat
Q page 204, Child Safety .
A WARNING
A child in a rearward-facing child safety
s e at insta lled on the front passenger seat
w ill be seriously injured and can be k illed if
t he fr ont a irbag inflates - even with an Ad­
vanced Airbag System.
- T he i nflating a irbag will hit the child
safety seat or infant carrier wit h great

the ch ild .
A WARNING
If, in exceptional c ircumstances, you must
install a forward-facing child restra int on
the front passenger's seat: -
Always make sure the forward-facing
seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and s ide a irbag .
- Never put the forward-facing child re­
straint up against or very near the instru­ ment panel.
- Always move the passenger seat into its
rearmost pos ition in the seat's fore a nd
aft ad justment range, as fa r away from
the airbag as possible b efore installing
the forwa rd-fa cing ch ild restra int. The
b ackrest mus t be a djusted to a n up right
position.
- Make s ure that the

Important safety instructions on
monitoring the Advanced Airbag System
_&. WARNING
An airbag system that is not functioning
prope rly cannot provide supplemental pro­
tect ion in a frontal crash.
- If the airbag indicator light
c::> page 16
comes when the vehicle is be ing used,
have the system inspected immediately
by you r authorized Aud i dea ler.
It is pos­
sible that the airbag will inflate when it
is not supposed to, or w ill not inflate
when it should .
_&. WARNING
If the front airbag inflates, a child witho ut
a child restraint, or in a rearward-facing
child safety seat, or in a forward-facing
child restraint that has not been properly
installed will be seriously injured and can
be killed .
- Even though your veh icle is equipped
with an Advanced Airbag System, make certain that all children, especially 12
years and younger, a lways ride on the
back seat properly restrained for their
age and size.
- Always install forwa rd or rear-facing
child safety seats on the rear seat -even
with an Advanced Airbag System. -
If you must install a rearward-facing
child safety seat on the front passenger
seat because of exceptional c ircumstan­
ces and the

light does not appear and stay on, imme­
diate ly install the rear-facing child safety
seat in a rear seat ing pos ition and have
the airbag system inspected by your au­
thorized A udi dealer.
- A tight tether or other strap on a rear­ ward-facing child restraint attached to the front passenger seat can p ut too
m uch pressure on the weight-sensing
mat in the seat and register more weight
than is actually on the seat. The heavier
weight registered can make the system
work as though an adult were on the seat
and deploy the Advanced Airbag when it
must be suppressed causing ser ious or
even fata l injury to the ch ild.
- If, in exceptional circumstances, you
must install a forward-fac ing ch ild re­
straint on the front passenger seat, al ­
ways move the seat into its rearmos t po­
sition in the seat's fore and aft adjust­
ment range, as far away from the airbag

with different tread depths. For details see

page 284, New tires and replacing
tires and wheels .
.&_ WARNING
Always adjust your driving to road and traf­
fic conditions . Do not let the extra safety
afforded by all-wheel dr ive tempt you into
tak ing extra risks.
-Although the all-wheel dr ive is very ef­
fective, always remember that braking
capacity is limited by t ire traction . You
sho uld therefore not dr ive at excessive
speeds on icy or s lippery road surfaces.
- On wet road su rfaces, be careful not to
dr ive too fast because t he front wheels
cou ld beg in to s lide on top of the wa ter
(aquaplaning). If this sho uld occ ur, you
w ill have no warning from a sudden in­
crease in engine speed as with a front­
whee l drive vehicle. A lways drive at
speeds wh ich are suited to the road con­
ditions -risk of c rash.
Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting
the engine.
I f a vehicle w it h a conventional energy system
i s not driven for a long pe riod of time, the bat­
tery is disch arged by idling c urrent cons umers
(e .g. immobilizer) . In ce rtain c ircumstances it
can result in there being insufficient energy
ava ilab le to start the engine .
I n tell igen t energy management in your vehi ­
cle hand les the d istribution of electrical ener ­
gy . Starting abi lity is marked ly imp roved and
the life of the battery is extended.

Basica lly, energy management consis ts of
batte ry diagnosi s, idling cur rent manage­
ment
and dynamic energy management.
Battery diagnosis
B attery diagnosis continuously de termines
the state of the battery . Sensors determine
batte ry voltage, battery current and battery
temperature . This determines the current
state of charge and the power of the battery.
Idling current management
Id lin g cur ren t man agement reduces energy
consumption while the vehi cle is standing.
With the ig nition switched off, it controls the
energy supply to the various electrical compo­ nents. Data from battery diagnos is is cons id­
ered.
Depend ing on the battery's state of cha rge,
individual cons umers are gradually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability.
Dynamic energy manag ement
While the vehicle is being driven, dynamic en ­
ergy management distrib utes the energy ge n­
erated according to the needs of the individ u­
al components. It regulates consumption, so
that more electrical energy is not being used
than is be ing generated and ensures an opti­
mal state of charge for the battery .
(D Tips
-But even e nergy management cannot
negate the limits of physics. Consider
t hat the powe r and l ife of a bat tery are
l imited.
- If start ing ability is threatened, you are
informed by a warning ¢
