power steering AUDI A4 2016 User Guide

Inte llig ent Techn olo gy
In extreme cases, EDL automatically switches off
to help keep the brake on the braked wheel from
overheating. EDL will switch on aga in automati­
cally when conditions have returned to normal.
St eer ing r ecomm endation
The ESC helps to stabilize the vehicle by chang ing
the steering torque .
I n vehicles with dynamic steering*, ESC also
helps to stabilize the stee ring in critical situa­
tions.
Electron ic inter axle differential lock*/
sel ective whe el t orque control *
The electronic interaxle differentia l lock (front
wheel drive) or the selective wheel torque control
(a ll whee l drive) operates when driving through
curves . The front wheel on the inside of the curve
or both wheels on the inside of the curve are
braked selectively as needed. This allows more
precise driving in curves. The applicable system
may not activate when driving in wet or snowy
conditions.
.,&. WARNING
- The ESC and its in tegrated systems canno t
overcome the laws of phys ics. This is espe­
c ially important on slippery or wet roads.
If
the systems begin acting to stabilize your
Switching on /off
vehicle, you should immediately change
your speed to match the road and traffic
conditions. Do not let the increased safety
provided by these systems tempt you to
take risks. Doing so will increase the risk of
a loss of vehicle control, collision and seri­
ous personal injuries.
- Always adapt your speed to road, traffic and
weather conditions. The risk of los ing con­
trol of the vehicle increases when driving
too fast, espec ially through curves and on
slippery o r wet roads, and when driving too
close to vehicles up ahead . The ESC and its
integrated systems cannot always prevent
collisions -there is still a risk of accidents!
- Always accelerate with specia l care on even,
smooth surfaces such as those that are wet
or covered with ice and snow. The drive
wheels can spin even with these assistance
systems that cannot always help to reduce
the risk of loss of vehicle control.
@ Tips
- ABS and ASR only work correct ly when all
four wheels are equipped with identical
t ires. Different tire sizes can lead to a reduc­
t ion in engine power.
- You may hear noises when the systems de­
scribed are working.
ESC turns on automatically when you start the engine .

The ESC is des igned to function in levels. Depend­
i n g on the level tha t is selected, the stabilization
function of the ESC is limited or switched off. The

the p urpose of clean ing the brake system
only if road conditions permit. Other road
users must not be put at risk - you may
cause an accident!
- Before descend ing a steep grade, reduce
speed and shift transm iss io n into a lower
gear or lowe r d riv ing range. Do not ride the
bra kes or hold the pedal down too long or
t oo often. This could ca use the bra kes to get
hot an d diminish brak ing efficiency.
- Do not "r ide t he b rakes" by resting your foot
on the pe dal when yo u do not inten d to
br ak e. This may cause the br akes to over­
heat, p remat ure wea r and increased stop ­
ping distance.
- Under certa in climatic and operating condi­
tions such as passing thro ugh water, driving
in heavy ra in or after washing the vehicle,
the effectiveness of the brakes can be re ­
duced. In w inte r, ice can acc umulate on the
brake pads, linings, discs and drums. Care­
fully apply brakes for a test. Brakes will dry and ice coatings w ill be cleaned off after a
few careful b rake applica tions.
- Driv ing for an ex tended period of time on
salt-covered roads witho ut using your
bra kes can also affe ct bra king efficie ncy .
C le an off a ccumula ted s alt co ating from
bra ke discs and pads with a few caref ul
bra ke app lications.
- If you dam age the fro nt sp oiler, or if yo u in­
st all a diff erent spoi le r, be sure the ai r flow
to the front brakes is not obstr ucte d. Othe r­
wise the bra ke system could overheat reduc ­
ing the e ffectiveness of the entire b rake sys­
tem.
- Failure of one brake circuit will impair the
brak ing capability resulting in an increased
stopp ing distance. Avoid driving the vehicle
and have it towed to the nearest authorized
Audi dealer or qualif ied workshop.
- Never let the veh icle roll to a stop w ith the
engi ne shut off .
-If the brake booster is not working, the
bra ke pedal m ust be pressed conside rably
harder to make up for the lac k of booster
assista nee .

Indicator lights and messages
• Steering defective! Do not drive vehicle!
If this indicator light turns on and stays on and
t hi s message appears, the power steering may
have failed.
Do
not continue driving. See your author ized
Audi dealer or a qualified repair facility for assis­
tance.
' :r, y Dynamic steering: System fault! You can
continue d riving
If the indic ator l igh t turns on and the message
appe ars, the steering may be more diffic ult to

(D Tips
- If the . or
,~ n ind icator light only stays on
fo r a short time, you may continue driving.
- The dynamic steering* stability systems are
not available in the event of a system mal­
funct ion.
- Fo r additional information on dynamic
steering*, refer to¢

Driving with your
quattro
Applies to veh icles: w ith all-wheel drive
With all-wheel drive, all four wheels are driven.
General information
With all-whee l drive, power is distributed to all
four wheels . This happens automatically depend­
ing on your dr iv ing style and the road condit ions
at the time . See also ¢
page 177 .
A center differentia l distrib utes the driv ing power
variably to the front and rear axle. It works to­ gether with selective wheel torque control, which
activates when driving through curves
¢
page 178 . With the sport differentia l*, power
d istr ibut io n to the rear wheels is variable and can
be adj usted w ith d rive select¢
page 111.
The all -wheel drive concept is designed for high
engine power . Your veh icle is exceptionally pow­
erful and has excellent driving characterist ics
both under normal dr iv ing condit io ns and on
snow and ice. Always read and fo llow safety pre­
cautions ¢
A.
Winter tires
When d rivi ng in the winter, your vehicle with all­
wheel drive has an advantage, eve n with regular
tires. In winter road conditions it may be adv isa­
b le to mount w inte r ti res (or all-season tires) fo r
improved driveability and braking: these tires
must be mounted on all four wheels . See a lso
¢ page 232, Winter tires.
Tire chains
Where ti re chains are mandatory on certain
roads, this norma lly also applies to vehicles w ith
all -whee l drive ¢
page 233, Snow chains .
182
Replacing wheels /tires
Vehicles with all-wheel d rive must a lways have
tires of the same size. Also avoid t ires with differ ­
ent tread depths. For detai ls see page
¢ page 224, New tires or wheels .
Off-Road driving?
You r A udi does not have eno ugh ground clear­
an ce to be used as an off-road vehicle.
It is there­
fore best to avoid ro ugh tracks and uneven ter ­
rain as much as possib le. Also refer to
¢ page 185.
A WARNING
A lways adjust your dr iving to road and traffic
conditions . Do not let the extra safety afford­
ed by all-whee l drive tempt you into taking
extra risks .
- Although the all-wheel drive is very effec­
tive, always remember that braking capacity
is limited by ti re tract ion. You s hou ld there­
fore not drive at excessive speeds on icy or
slippe ry road s urfaces.
- On wet road surfaces, be careful not to dr ive
too fast because the front wheels could be­
gi n to slide on top of the water (aquaplan­
ing) . If th is should occur, you will have no
warning from a s udden increase in engine
speed as with a front-wheel drive vehicle.
Always drive at speeds which are suited to
the road conditions -risk of crash .
Energy management
Starting ability is optimized
Energy management controls the distribution of
electrical energy and thus optimizes the availa­
bility of electrical energy for starting the engine .
If a vehicle with a conventional energy system is
not driven for a long period of time, the batte ry is
discharged by id ling current consumers (e.g . im­
mobilizer). In ce rtain circumstances it can resu lt
i n the re being insufficient energy avai lab le to
start the engine .
