steering AUDI A4 2018 Owner's Manual

Driving
-To reduce the risk of an accident, never se­lect the R or P positions while driving.
-Do not inadvertently press the accelerator
pedal when the vehicle is stationary. Other­
wise the risk of an accident increases be­
cause the vehicle will start to move immedi­
ately, even if the parking brake is set.
(D Tips
For safety reasons, the parking brake only re­
leases automatically when the driver's door is
closed.
Hill descent control
A pp lies to: ve hicles w ith automat ic tra nsmissio ns
The hill descent control system assists the driver
when driving down hills.
Hill descent control activates when the transmis­
sion is in the Dor S position and you press the
brake pedal. The transmiss ion automatically se­
lects a gear that is suitable for the hill. Hill de­
scent control tries to maintain the speed ach­
ieved at the time of braking, within physical and
technical limitations. If may still be necessary to
adjust the speed with the brake pedal.
Hill descent control switches off once the hill lev­
els out or you press the accelerator pedal.
When operating the cru ise contro l system*
c:;, page 102, hill descent control is also activated
when the speed is set.
A WARNING
Hill descent control cannot overcome physical
limitations, so it may not be able to maintain
a constant speed under all conditions. Always
be ready to apply the brakes.

The transmission automatically shifts up or down before critical engine speed is reached.
The transmission only allows manual shifting
when the engine speed is within the permitted
range.
@ Tips
- If you shift to the next lowest gear, the
transmission will only shift if the engine will
not be over-revved.
- With kick-down, the transmission shifts to a
lower gear, depending on vehicle speed and
engine speed.
- tiptronic does not work if the transmission
is running in emergency mode.
Kick-down
Applies to: vehicles with automatic transm issions
Kick-down enables maximum acceleration.
When you press the accelerator pedal down be­
yond the resistance point, the automatic trans ­
mission downshifts into a lower gear and the en­
gine utilizes its full power , depending on vehicle
speed and engine RPM. It shifts up into the next
higher gear once the maximum specified engine
RPM is reached.
A WARNING
Please note that the wheels could spin on
slick or slippery roads when kick-down is ac­
tive .

Predictive efficiency
assist
Descript ion
Applies to: vehicles with predictive efficiency assist
General information
The pred ictive eff ic iency assist helps the driver to
d rive w ith anticipation and therefore helps to
save fuel. The system accesses predictive trip da­
ta (including speed limits, inclines and the radius
of curves) from the navigation system*. Informa­
tion from the camera-based traff ic sign recogni­
tion* is also applied to recognize traffic signs
r;;:;ipage 104.
The messages displayed depend on the naviga­
tion data* being up-to-date and the correct iden­
tification by the traffic sign recognition*.
When adaptive cruise contro l* is switched off,
the predictive efficiency assist only provides noti­
fications without controlled interventions. When
adaptive cruise control* is switched on, the sys­
tem responds to upcoming situations automati­
cally.
Vehicles with adaptive cruise control*
Refer to predictive control c> page 115.
Indicator in the instrument cluster display
Predictive messages appea r in the instr ument
cluster display to show the driver the appropriate
time to coast when a situation ahead requires
you to drive at a lower speed.
The messages are only shown if the cr uise control
system* or adaptive cruise control* is switched
off .

Audi pre sense front
Description
Applies to: veh icles with Audi adaptive cruise control
Within the limits of the system, pre sense front
can warn you of impending collisions and initiate
the corresponding braking maneuvers or the sup­ porting measures when avoiding a collision .
If detected in time, the system can rank the dan­
gerous situation as critical if a vehicle driving
ahead brakes suddenly, if your own vehicle is ap­
proaching a significantly slower vehicle at high
speed or when there is an oncoming vehicle dur­
in g a turning maneuver .
If detection is not possible, then pre sense front
does not react .
Warnings
Applies to: ve hicles with Audi adaptive cruise control
Fig. 122 In strument cluste r: approac h warning
General information
The system recognizes various dangerous situa­
tions . The
early warning occurs if:
-a vehicle driving ahead brakes suddenly,
-your own vehicle approaches a significantly
a s lower vehicle or stationary vehicle in the direc-co
;::; tion of travel. ,....
N .... 0 0
3 1) This is not availa ble in some co untrie s. co
Assistance systems
When this warning occurs, it may only be possi­
ble to avoid a collision by swerving or braking
strongly. The message
Audi pre sense.
¢ fig. 122 and a warning tone will warn you
about the danger .
If you do not react enough or not at all to a dan­
gerous situation that was detected by the sys­
tem, pre sense front provides assistance by ap­ plying the brakes .
If a collision is imminent, the system will first
provide an
acute warning by braking sharply. You
will also warned by an indicator in the instrument
cluster
display¢ fig. 122. If you do not react to
the acute warning, pre sense front can brake with i ncreasing fo rce within the limits of the
system
1>. This reduces the vehicle speed in the
event of a collision. At low vehicle speeds, pre
sense front can in itiate a complete deceleration
shortly before a collision with a vehicle driving
ahead
l). If pre sense front determines that you
are not braking strongly enough when a collision
is imminent, it can increase the braking force.
T he following functions trigger in conjunction
with pre sense basic/rear at corresponding vehi ­
cle speeds:
-Reversible tensioning of the front safety belts.
-Closing the windows and sunroof* .
-Inflating the side bolsters* on the seat back-
rest .
Audi drive select*: depending on the mode se­ lected, the reversible belt tensioner, the closing
of the w indows and sunroof*, and the inflating of
the side bolsters* on the seat backrest may not be active.
Evasive steering support
Evasive steering support helps you to steer the
vehicle around an obstacle in a critical situation .
If you avo id an obstacle after the acute warning,
then the evasive steer ing support ass ists you by
applying slight stee ring adjustment to correct
.,.
121

Ass is tan ce sys tems
your steering whee l ang le as long as you are ac­
tively steering. Evasive steering support is availa­
b le at speeds between approximately 20 mph
(30 km/h) and 90 mph (150 km/h).
Tu rn assist
When start ing to drive and up to speeds of maxi­
mum
6 mph (10 km/h), the turn assist uses a
braking intervention to prevent your vehicle from
colliding with an oncoming vehicle when turning
left or right (available in certain countries). The
braking intervent ion causes your vehicle to stay
in its lane.
A WARNING
-Pre sense front cannot overcome the laws of
physics.
It is a system des igned to assist and
it cannot prevent a collision in every circum­
stance. The driver must always i ntervene.
T he driver is always responsib le for braking
at the correct time. Do not let the increased
safety provided tempt you into taking risks .
This could increase your risk of a collision.
- The system can deploy incorrectly due to
system-specific limits .
- Please note that the sensors and the camera
do not always detect all objects or lane
markings. This increases the risk of an acci­
dent.
- Pre sense front does not react to people, an­
imals or ob jects that are crossing the veh i­
cle's path or that are difficu lt to
detect¢ .&.
in General information on page 109.
-Reflective objects such as guard rails or the
entrance to a tunnel, heavy rain and ice can
affect the fu nction of the radar sensors and
the system's ability to detect a coll is ion risk .
(D Note
The sensors can be displaced by impacts or
damage to the bumper, whee l housing and
underbody. Pre sense front can be impa ired
by this. Have an authorized Aud i dealer or au­
thorized Audi Service Fac ility check their func­
tion.

(D Tips
- You can cancel the braking with increas ing
force that is initiated by the system by bra k­
ing yourself, by acce lerating not iceably or
by swerving.
- Keep in mind that pre sense front can brake
unexpectedly. Always secure any cargo or
objects that you are transporting to reduce
the risk of damage or injury.
- Specific pre sense front functions switch off
when the ESC is restricted or sw itched off

Applies to: ve hicles wit h Aud i act ive lane ass ist
Active lane assist (lane departure warning) de­
tects lane marker lines within the limits of the
system using a camera in the windshield . If you
are approach ing a detected lane marker line and
it appears likely that you will leave the lane, the
system w ill wa rn you w it h corre ct ive steer ing .
You can overr ide th is steering at any time . If yo u
pass over a line, the steer ing whee l wi ll vibrate
lightly. In order for this warning vibration to oc ­
cur, it must first be switched on in the Infotain­
ment system. Active lane assist is ready for oper­
ation when the lane marker line is detected on at least one side of the vehicle.
The system is designed for driving on express ­
ways and highways and therefore only activates at speeds above approximately 40 mph (6S km/
h).
Applies to: vehicles with side assist: if you acti­
vate a turn signal when active lane assist is ready
and it classif ies a lane change as critical because
of vehicles traveling alongside you or approach­ ing you, there w ill be not iceable correct ive steer­
i ng shortly before you leave the lane . This will at­
tempt to keep your veh icle in the la ne.
Applies to: vehicles w ithout s ide ass ist : the ready
system does not warn you if you activate a turn
A ss ista nce sys te m s
signal before crossing the lane marker line. In
t h is case, it assumes that you are changing lanes
intentionally .
Applies to: vehicles wi th adap tive c ruise contro l:
there is no corrective steering or warnings if the
system recognizes a distinct passing maneuver .
If the condit ions are met, traffic jam ass ist
switches on at speeds under approximately
40 mph (65 km/h)

A WARNING
=
- The system warns the driver that the vehicle
is leaving the lane using corrective steering.
The driver is always responsible fo r keeping
the vehicle within the lane.
- The system can help you keep the vehicle in
the lane, but it does not drive by itself. Al­
ways keep your hands on the stee ring
wheel.
- Cor rective stee ring may not occur in certain
situations, such as during heavy b raking.
- There may be cases whe re the camera does
not recognize all lane marker lines. Cor rec­
tive steering can only take place on the s ide
of the vehicle where lane marker lines are
detected.
- Other road structu res or objects could poss i­
b ly be identified unintentionally as lane
marker lines . As a result, corrective steering
may be unexpected or may not occur.
- The camera view can be restricted, for ex­
ample by vehicles driving ahead or by rain,
snow, heavy spray or light shining into the
camera. Th is can result in active lane ass ist
not detecting the lane marker lines or de­
tect ing them incorrectly .
- In certain s ituations where visibility is low,
the vehicle may switch from an "early" to
"late" steering correct ion.
- Under certain condit ions such as ruts in the
road, an inclined roadway or crosswinds, the
correct ive steer ing alo ne may not be enough
to keep the vehicle in the middle of the lane .
- For safety reasons, act ive lane assist must
not be used when there are poor road and/
or weather conditions such as slippery roads, fog, gravel, heavy rain, snow and the
