The model-specific standard and optional equipment can be found in the index from page 124 onwards.
Technology/safety
Seat belts
3-point inertia reel seat belts for all seats, with belt
force limiters, seat belt tensioners and front seat-belt
reminder; colour-coordinated with the interior
Instrument cluster
with adjustable lighting, electronic speedometer with
odometer and trip odometer, rev counter and automatic
ready-check when engine starts, radio-controlled clock
(GPS clock in conjunction with MMI navigation plus),
coolant temperature display and fuel gauge; S4/S4
Avant: with S-specific grey dials, white needles and
S4 logo in the rev counter
Safety steering column
includes a shunt mechanism with damping function
to supplement the protection offered by the seat belts
and airbags
First-aid kit
in the storage compartment in the rear centre armrest
Warning triangle
with bracket on the inside of the tailgate
Anti-Slip Regulation (ASR)
for improved traction, reduces spinning of the drive wheels
Electronic Differential Lock (EDL)
On surfaces with varying levels of grip, this start-off
assistant automatically brakes the drive wheels on any
surface that is too slippery, thereby ensuring smooth,
powerful progress; operates at speeds up to approx.
100 km/h.
Electronic Stability Control (ESC)
networks the ABS, EBD, ASR and EDL with its own
sensors and compares the driving data with reference
data; provides better stability at all speeds by targeted
braking of individual wheels and intervention in the
engine management system
ESC with electronic axle-differential lock
The electronic axle-differential lock function is
integrated in the ESC on front-wheel drive models. It
distributes the drive torque by means of targeted
braking actions, depending on the driving situation.
The axle-differential lock actively countersteers in
corners. The result is improved traction and dynamic
performance when cornering and more precise and
neutral handling (less understeer). Agility during
steering is also improved.
Electromechanical power steering
maintenance-free rack & pinion steering with speed-
dependent power steering; precise steering feel at
high speeds, excellent assistance when parking
Manual transmission
6-speed, all-synchromesh, hydraulically-actuated dry
clutch with asbestos-free linings, 2-mass flywheel
multitronic
the multitronic generation of continuously variable
transmissions, featuring dynamic gear control
program (DCP) and sport program, 8 different gears
can be selected in manual mode, hydraulically
controlled multi-plate clutch
Body, galvanised
(fully-galvanised in areas at risk from corrosion),
unitary construction, welded to the floor pan, front
and rear areas feature defined crumple zones,
aluminium front wings. (12 year guarantee against
rust perforation)
Airbags
adaptive front-end collision protection with seat
position recognition and full-size airbag for driver and
front passenger; side airbags at front (thorax/pelvis
airbag); including head airbag system, unfolds over
the entire length of the side windows in the area of the
1
st
and 2
nd
row of seats and protects the passengers in
the front and rear seats in the event of a side impact
Side airbags, rear
supplement the side impact protection in the doors
(thorax/pelvis airbags)
Integrated head restraint system
In the event of a rear-end collision, the design of the
seats stabilises the upper torso and provides better
support for the head. This increases the level of
protection and reduces the risk of a whiplash injury.
Suspension/brakes
Sports suspension
vehicle lowered by approx. 20 mm compared with
dynamic suspension, with stiffer spring and damper
tuning for more direct contact with the road and
sporty handling
S line sports suspension
with more dynamic suspension tuning and vehicle
lowered by a further 10 mm compared with sports
suspension
S sports suspension
with stiffer spring and damper tuning for more direct
contact with the road and sporty handling; 5-link
lightweight front axle, tubular anti-roll bar,
trapezoidal-link rear axle with independent wheel
suspension; twin-tube gas-filled shock absorbers and
coil springs, front axle carrier rigidly fixed to the body,
flexibly mounted axle supports at rear
Brake system
dual-circuit with diagonally-split brake system,
Antilock Brake System (ABS) with Electronic Brake
force Distribution (EBD), Electronic Stability Control
(ESC) with brake assist, tandem brake booster, disc
brakes front/rear, ventilated at front
Brake callipers
for S4/S4 Avant: painted black, at the front with
S4 emblem
Electromechanical parking brake
includes parking brake function when stationary,
drive-off assistance function by means of automatic
release when driving away and emergency braking
function whilst driving by means of action on all
4 wheels
