four wheel drive AUDI S5 COUPE 2016 Owners Manual

Emergency braking
In the event that the conventional brake system
fails or locks.
11-In an emergency, pull the sw itch @c:> page 77,
fig. 80 and cont inue to pull it to slow your vehi­
cle down with the park ing brake .
11-As soon as you release the switch @ or acceler-
ate, the brak ing p rocess stops.
If you pull the sw itch @and hold it above a
speed of about
5 mph (8 km/h), the emergency
braking function is in itiated. The vehicle is braked
at all four wheels by activating the hydrau lic
b rake system. The brake performance is sim ila r
to making an eme rgency stop c:>
.&..
In order not to activate the emergency brak ing by
mistake, an audib le wa rning tone (buzze r)
sounds when the sw itch @ is pulled . As soon as
the switch @is re leased, or the acce lerator peda l
is depressed, emergency braking stops.
A WARNING
Emergency braking should only be used in an
emergency, when the normal foot brake has
failed or the brake pedal is obstructed. Using the parking brake to perform emergency
brak ing will slow your vehicle down as if you
had made a full bra ke appl ication . The laws of
physics cannot be suspended even with ESC
and its associated components (ABS, ASR, EDS). In corners and when road or weather
conditions a re bad, a f ull brake application
can ca use the vehicle to skid or the rear end to
break away- risking an accident.
Speed warning system
Overview
The speed warning sys tem helps you to keep your
driving speed below a set speed limit .
The speed warning system warns if the driver ex ­
ceeds a prev iously stored maximum speed. A
;::; warning tone w ill sound as soon as the vehicle
0 ~ speed exceeds the set speed by about 3 mph
~ (3 km/h). At the same time , a warning symbol Lil ,...., v:, ,....,
D riv ing
appea rs in the display. The symbo l's appearance
might be diff erent in some models.
T he speed warn ing system has two warning
thresholds that function independently of each
othe r and that have somewhat different p urpos­
es:
Speed warning 1
You can use speed warning 1 to set the max imum
speed w hile you are dr iving . T his sett ing will re ­
main in effect until you tu rn off the ignit ion, as­
sum ing that you have not changed o r reset the
setting .
T he . (USA models) /. (Canada models)
speed wa rning symbo l in the warning 1 disp lay
appears when you exceed the maximum speed .
It
goes out when the speed falls below the stored
maximum speed.
T he speed warn ing symbol will also go out if the
speed
exceeds the stored maximum speed by
more than about 2S mph
(40 km/h) for at least
10 seconds. The stored maximum speed is delet­
ed.
Sp eed wa rning 2
Storing warning 2 is recommended if you always
want to be reminded of a certain speed, for ex­
amp le wh en you are trav eling in a country that
has a genera l maximum speed limit, or if you do
not want to exceed a specified speed for winter
t ires .
T he . (USA models) /. (Canada mod els)
speed warning 2 symbol appears in the display
when you exceed the stored speed limi t. Unlike
warning 1 , it wilt not go out unt il the vehicle
speed drops below the stored speed limit .

{D Tips
Even though your vehicle is eq uipped with a
speed warning system, you should still watch
the speedometer to make sure you are not
driving faster than the speed lim it.

Steering recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque .
In vehicles with dynamic steering*, ESC also
helps to stabilize the steering in critical situa­
tions.
Electronic interaxle differential lock*/
selective wheel torque control*
The electronic interaxle differential lock (front
wheel drive) or the selective wheel torque control
(all wheel 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 integrated systems cannot
overcome the laws of phys ics. Th is is espe ­
cially important on slippery or wet roads.
If
the systems begin acting to stabilize your
Switching on /off
Intelligent Technology
veh icle, 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 losing con­
trol of the vehicle increases when driving
too fast, especially through curves and on
slippery or 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 special 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 correctly when all
four wheels are equipped with identical
tires. Different tire sizes can lead to a reduc­
tion in engine power.
- You may hear noises when the systems de­
scribed are working .
ESC turns on automatically when you start the engine.
Fig. 152 Version A: lower center console,~ OFF button
The ESC is designed to function in levels. Depend­
ing on the level that is selected, the stabilization
function of the ESC is limited or switched off. The
Fig. 153 Version B: upper center console,~ OFF button
amount of stabilization control will differ de­
pending on the level.

Intelligent Technology
Clean off accumulated salt coating from
brake discs and pads with a few caref ul
brake app lications.
- If you damage the front spoiler, or if yo u in­
stall a d ifferent spoiler, be sure the air flow
to the front brakes is not obstructed. Other­
wise the brake system could overheat reduc­
ing the effectiveness of the entire b rake sys­
tem.
- Failure of one brake c ircuit will impair the
bra king capability res ult in g in an increased
stopp ing distance. Avoid driving the vehicle
and h ave i t towe d to the ne arest author ized
Audi dealer or quali fied workshop.
- Never let the vehicle roll to a s to p wi th the
eng ine shut off.

,&.
Winter t ire s
When driving in the winter, your vehicle with a ll­
wheel drive has an advantage, even with regular
tires. In winter road conditions it may be adv isa­
ble to mount w inter tires (or all-season tires) for
i mproved driveab ility and brak ing : these tires
must be mounted on
all four wheels . See also
<=> page 220, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this normally also applies to vehicles w it h
all -wheel drive <=>
page 220, Snow chains.
Replacing wheels /tires
Vehicles with all-whee l dr ive must always have
tires of the same size. A lso avoid tires with differ­
ent tread depths. For details see page
<=>
page 212, New tires or wheels.
Off-Road dri ving ?
Your Aud i does not have enough ground clear­
ance to be used as an off-road vehicle.
It is there­
fore best to avoid rough tracks and uneven ter­ rain as much as possible . Also refer to
<=> page 177 .
A WARNING
Always adjust your driving to road and t raff ic
conditions. Do not let the extra safety affo rd­
ed by all-wheel drive temp t yo u into ta king
extra risks.
- Although the all-whee l drive is very effec­
t ive, a lways remember th at br akin g capac ity
is limited by tire traction. Yo u should t here­
f ore not drive at excess ive speeds on icy or
slippery road surfaces.
- On wet road surfaces, be caref ul no t to drive
too fast because the front wheels co uld be ­
gin to slide on top of the water (aq uaplan­
ing). If this shou ld occur, you wi ll have no
Intellig ent Technology
warn ing from a s udden increase in engine
speed as w ith 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
elec trical energy and thus optimizes the availa­
bility of ele ctrical energy for star ting the engine.
If a vehicle with a conventiona l energy system is
not dr iven fo r a long pe riod of time, the batte ry is
discharged by id ling curre nt cons umers (e.g. im ­
mobili ze r). In cer tain circumstances i t can res ult
in the re being insuffi cien t energy ava ilable to
start the engine .
Intellige nt energy manageme nt in yo ur vehicle
hand les the distri bu tion of elec trical energy.
Start ing ability is markedly improved and the life
of the battery is extended .
B as ic all y, energy managemen t cons ists of

Battery diagnosis
Battery d iagnosis con tinuously dete rmines the
state of the bat tery. Sensors de termine battery
vo ltage, b attery curren t and batte ry tempera­
tu re. This de termines t he current state of charge
and the power of the battery .
Idling current management
Idling cur rent management reduces ene rgy con­
s u mption wh ile the vehicle is standi ng. With the
ignition swi tched off , it co ntrols the energy sup­
ply to the vario us elec trical components . Data
from battery diagnosis is considered .
Depend ing on the ba tte ry's s ta te of charge, indi­
v idual consumers are g radually turned off to pre­
ven t excess ive d ischarge of the battery and thus
maintain starting capab il ity.

New tires or wheels
Audi recommends having all work
on tires or wheels performed by
an authorized Audi dealer or au­
thorized Audi Service Facility.
These facilities have the proper knowledge and are equipped with
the required tools and replace­
ment parts.
.,.New tires do not yet have the
optimum adhesion properties. Drive carefully and at moderate
speeds for the first 350 miles (500 km) with new tires .
.,.Use tires of the same construc­
tion, size (rolling circumference)
and as close to the same tread
pattern as possible on all four
wheels .
212
.,.Do not replace tires individually.
At least replace both tires on the
same axle at the same time.
.,.Audi recommends that you use
Audi Original equipment tires. If
you would like to use different
tires, please note that the tires may perform differently even if
they are the same size ¢
,&.
.,. If you would like to equip your
vehicle with a tire/rim combina­
tion that is different from what
was installed at the factory, con­
sult with an authorized Audi dealer or authorized Audi Service
Facility before making a pur­
chase ¢&, .
The spare tire* is different from
the regular tires installed on the
vehicle -for example, if winter
tires or wide tires are installed -
then only use the spare tire* tem­
porarily in case of emergency and
drive carefully while it is in use. It
should be replaced with a regular
tire as soon as possible.
On
all wheel drive vehicles, all
four wheels must be equipped
with tires that are the same brand and have the same construction
and tread pattern so that the
drive system is not damaged by .,.

Wheels
and a special procedure. You must not repair or
disassemble them¢&. .
A WARNING
Wheel bolts that are tightened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct t ightening specifi ­
cation, refer to ¢
page 22 7, After changing a
wheel .
-Always keep the wheel bolts and the
threads in the wheel hub clean and free of
grease.
- Only use wheel bolts that fit the rim .
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Aud i
Service Facility . Never repair or disassemble
rims yourself, because this inc reases the risk
of an accident.
Winter tires
Winter tires s ignificantly improve the vehicle's
handling when driving in winter conditions . Be­
cause of their construction (width, compound,
tread pattern), summer tires provide l ess trac­
tion on ice and snow.
.,. Use winter tires on all four wheels.
.,. Only use winter tires that are approved for your
vehicle.
.,. Please note that the maximum permitted
speed may be lower with winter tires
q .&,. . An
authori zed Audi dealer or authori zed Audi Serv­
ice Facility can inform you about the maximum
permitted speed for your tires .
.,. Check the tire pressure after install ing wheels
q page 215.
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0 .157 in (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re­
gardless of the remaining tread.
A WARNING
- Never drive faster than the maximum per­
mitted speed for your tires. This could cause
the tires to heat up too much. This increases
220
-
the risk of an accident because it can cause
the tire to burst.
- Always adapt your driving to the road and
traffic conditions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter tires can lose traction on black ice .
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they prov ide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumpt ion .
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun­
tries where winter tires are required, only
winter tires w ith the ~ symbol may be per­
mitted.
Snow chains
Snow chains improve traction in the snow .
.,. Only install snow chains on the front wheels.
This applies also to vehicles with all wheel
drive* .
.,. Check and correct the seating of the snow
chains if necessary after driving a few feet. Fol­
low the instructions from the manufacturer.
.,. Note the maximum permitted speed when dr iv­
ing with snow chains. Do not exceed 30 mph (SO km/h).
Snow cha ins not only improve the
driving in win­
ter road conditions, but also the
braking .
Use of snow chains is only permitted with certain
rim/tire combinat ions due to technical reasons .
Check with an author ized Audi dealer or author­
ized Audi Service Facility to see if you may use
snow chains.
Use
fine-mesh snow chains. They must not add
more than 0.53 inch (13.5 mm) in height, includ­
ing the chain lock.
You must remove the chains when driving on
roads that are
free of snow . When roads are free ..,.
