A4 allroad quattro Audi S4 Saloon

Audi side assist
lane change assistant, working within system limits at
speeds of 30 km/h and above, the system uses radar
technology to monitor the area on the left, right and
behind the moving vehicle and informs or warns the
driver by means of an LED display in the relevant exte-
rior mirror if the Audi side assist has detected another
vehicle assessed as critical for lane-changing
adaptive cruise control
automatic distance control (control range 30 km/h
to 200 km/h); working within system limits, it uses
a radar sensor to detect vehicles ahead and maintain
this distance by automatic braking and accelerating;
4 distance levels and different driving modes can be
selected individually; including Audi pre sense front:
the Audi braking guard warns the driver about a
detected imminent collision with the vehicle in front
through an extended braking assist feature; extended
by the function of maximum deceleration: this is
initiated at speeds below 30 km/h if there is a danger
of collision with a stationary or moving vehicle in order
to avoid this collision if possible.
Suspension/brakes
Audi active lane assist
lane compliance assistant; supports the driver within
system limits comfortably in keeping in the lane
(operating range from approx. 60 km/h to 250 km/h).
If the system is activated and ready and the driver has
not operated the indicators, Audi active lane assist
will guide the vehicle within recognised lane boundary
lines by means of gentle, corrective steering inter-
vention; the driver can choose whether to be monitored
continuously or just shortly before crossing the traffic
lane marker (choice of earlier or later steering time);
additional steering vibration can be adjusted if the
driver wishes
Assistance package
The assistance package contains the functions of the
following assistance systems:
parking system plus (upgrade option to parking
system plus with reversing camera), Audi active lane
assist and adaptive cruise control.
Hold assist
holds the vehicle stationary for unlimited periods after
stopping in traffic on normal uphill and downhill
gradients. The system is activated by push-button and
allows the driver to drive away smoothly
Cruise control
at speeds of 30 km/h and above, the system keeps
the set speed constant, provided that engine power and
engine braking effect permit it; also features active
braking intervention, e.g. when driving downhill;
operated via separate steering column stalk; set speed
displayed in the driver information system
Parking system plus with rearview camera
acoustic and visual parking system for front and rear,
image of area behind the vehicle shown on the MMI
display, with dynamic display elements showing the
calculated path (steer-angle dependent); includes
help lines and guidelines for parking into cross parking
spaces and identification of point at which to apply
opposite lock when
parallel parking, reversing camera
integrated discreetly
in the handle strip of the luggage
compartment lid
Parking system plus
acoustic and visual parking system, front and rear,
with MMI display; measurement is by ultrasonic
sensors concealed in the bumpers
Parking system, rear
makes reverse parking easier within system limits by
indicating acoustically how far away the vehicle is from
an object detected behind the vehicle; measurement is
by ultrasonic sensors integrated discreetly in the
bumper
Audi drive select
changes vehicle characteristics e.g. by adapting power
steering assistance, accelerator and gear changing
characteristics, and the system also influences other
optional equipment; available modes: comfort,
auto, dynamic, efficiency and – in conjunction with
an MMI navigation system – individual. The efficiency
mode shifts the engine, automatic transmission,
climate control and optional adaptive cruise control
or cruise control into a consumption-optimised basic
setting.
Suspension with damper control
electronically controlled adaptation to different
driving situations (in S4 Saloon/S4 Avant on the basis
of the S sport suspension); dynamic or comfort-
oriented characteristic of the damper coordination,
can be adapted via Audi drive select
Dynamic suspension
providing outstanding handling and exceptional levels
of driving comfort with five-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
Sport suspension
vehicle lowered by 20 mm compared with dynamic
suspension, with stiffer spring and damper tuning for
more direct contact with the road and sporty handling
