2014 AUDI S4 parking brake

-Do not ride the brakes or press the brake
pedal too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases
braking distance or causes complete fail­
ure of the brake system.
- To prevent the vehicle from rolling back
when stopping on inclines, always hold it
in place with the brake pedal or parking
brake.
- Never hold the vehicle on an incline with
a slipping clutch. The clutch opens auto­
matically when it becomes too hot from
the overload. An indicator lamp
mJ illu­
minates and a driver message appears
¢ page 9 7 when the clutch is overload­
ed .
- If the engine must remain running, never
have any driving position engaged when
checking under the hood. Make sure the
selector lever has securely engaged and
is locked in P with the parking brake set
¢ page 214. Otherwise, any increase in
engine speed may set the vehicle in mo­
tion, even with the parking brake ap­ plied .
0 Note
-S tronic- and tiptronic transmission:
When stopping on an incline, do not try
to hold the vehicle in place by pressing
the accelerator pedal while a driving gear
is selected. This can cause the transmis­
sion to overheat and can damage it. Acti­
vate the parking brake or press the brake
pedal to prevent the vehicle from rolling.
- S tronic- and tiptronic transmission: Al­
lowing the vehicle to roll when the en­
gine is stopped and the selector lever is in N will damage the transmission be­
cause it is not lubricated under those cir­
cumstances .
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the driv ­
er's safety belt is engaged in the buckle.
Transmission 95
Hill descent control
App lies to vehicles : wi th mult itronic/ S tro nic/tiptro nic
The hill descent control system assists the
driver when driving down declines .
Hill descent control is activated when these­
lector lever is in D/S and you press the brake
pedal. The transmission automatically selects
a gear that is suitable for the incline. Hill de­ scent control tries to maintain the speed ach­
ieved at the time of braking, within physical
and technical limitations. It may still be nec­
essary to adjust the speed with the brakes.
Hill descent control switches off once the de­
cline levels out or you press the accelerator
pedal.
On vehicles with the cruise control system*
¢ page 89 , hill descent control is also activat­
ed when the speed is set.
.&_ 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 .

Homelink
Universal remote
control
Description
Appl ies to vehicles: wit h Homeli nk
The HomeLink universal remote control can
be programmed with the remote control for
devices that are already present.
W ith Home Link, you can control devices such
as the garage door, security systems, house lights, etc. comfortably from the inside of you
vehicle.
Homelink makes it possible for you to replace
three d ifferent remote controls from dev ices
in your home with one universal remote. This
feature works for most garage door and exte­
rior door motor signals. Programming the in­
div idual remote control for your remote con ­
trol takes place near the center of the radiator
grille. There is a control module attached at
this location .
A one -time programm ing of the sensor must
be performed before you are able to use sys­
tems with Home link. If the system does not
activate after performing the one-time pro­
gramm ing, check whether the system uses a
rolling code
q page 127 for vehicles without
the MMI*.
& WARNING
-
- Never use the Homelink transmitter
with any garage door opener that does
have not the safety stop and reverse fea­
ture as required by federa l safety stand­
ards. This includes any garage door open­
er model manufactured before April 1,
1982.
- A garage door opener which cannot de­
tect an object, signaling the door to stop
and reverse does not meet current feder­
al safety standards. Using a garage door
opener without these features increases
risk of serious injury or death. -
For safety reasons never release the
parking brake or start the engine while
anyone is standing in front of the vehicle.
- A garage door or an estate gate may
sometimes be set in motion when the
Homelink remote control is being pro­
grammed. If the device is repeatedly ac­
tivated, this can overstrain motor and
damage its e lectrica l components - an
overheated mo tor is a fire hazard!
- To avo id possib le injuries or property
damage, please always make abso lutely
certain that no persons or objects are lo­
cated in the range of motion of any
equipment being operated.

Trailer towing tips
Important to know
Your vehicle hand les different ly when tow ing
a trailer because o f the addit ional weight and
d iffe ren t weight distribution . Safety, perform ­
ance and economy w ill greatly depend on how
caref ully you load your trailer and operate
your rig.
B efore you actua lly tow your trailer, pr actice
turning, stopp ing and bac king up in an area
away from traffic. Keep practicing until you have become comp lete ly fam iliar with the way
your veh icle-trailer comb ination behaves and
responds.
Backing up is d ifficu lt a nd requires practice .
Backing up with a tra iler genera lly requires
steer ing action opposite to that when backing
up your vehicle without a trailer.
M aintain a g reater distance betwee n your ve­
h icle and the one in front o f you . You will need
mo re room to stop. To compensate for the
trailer, you will need a larger than normal
turning radius .
W hen pass ing, remember that yo u cannot ac ­
celerate as fast as yo u normally wo uld be­
cause of the added load. Make sure you have
e nough room to pass . After passing , allow
p lenty o f room fo r your tra iler before chang­
in g la nes aga in .
Avoid jerky starts, sharp turns or rap id lane
changes.
(D Tips
- Do not tow a tra iler during the break-in
period of you r vehicle.
- If you tow a trailer, your A udi may re­
quire more frequent maintenance due to
the extra load

Parking on a slope
Do not park on a slope with a trailer . If it can­
not be avoided, do so only after doing the fol­ lowing:
When parking:
.. App ly the foot brake.
.. Have someone p lace chocks under both the
veh icle and the tra iler wheels .
.,. With chocks in place, slowly release t he
bra kes unt il t he whee l chocks absorb the
load .
.. Tu rn the whee ls towards the curb.
.,. App ly the par king b rake .
.. Place an a utomatic transm ission* in P, re ­
spectively a manual transmission in first or
reverse gear.
When restarting after parking:
.,. App ly th e foot br ake .
.. Start the en gine.
.. Move the selector lever to D/S, respect ively
a man ual transmiss ion in first gea r.
.. Release the parking bra ke and s low ly pull
out and away from the wheel chocks .
.. Stop and have someone retr ieve the wheel
chocks.
@ Tips
If you move the selector leve r of the auto­
matic transmissio n* to P before applying
the pa rking brake and before blocking the
whee ls, you may hav e to use mor e forc e
l ater to move the le ver out of the P posi­
tion.
