2014 AUDI S4 Owners Manual

the engine is at its proper operating tempera­
ture and fuel economy has reached a normal
level. So you can see that you should avoid
short trips whenever possib le.
The
outside temperature is also critical in this
regard. Your car consumes more fuel in the
winter than in the summer .
allroad: Driving offroad
General information
Applies to vehicles: atlroad
When driving offroad, the funct ions for the
e lectronic stab ilization control (ESC) are ex­
panded. The ESC-Offroad-Mode can be activat­
ed in driving situations in which a wheel lock
or a differentia l lock function is needed
c::> page 188. In addit ion, your Audi provides
continuous all wheel drive .
Your Audi is however , not an offroad vehicle.
Never drive the vehicle in terrain which is not
suitable for the vehicle, or which exceeds
your driving skills. Never take any unneces­
sary risks!
After driving offroad
-After driving offroad, remove branches and
other debris from the radiator grille, under ­
body, and wheels. Look especially for objects
(stones) that have been caught in the tire
tread .
- Clean the body and the vehicle underbody
and inspect the vehicle for possible damag­
es.
- Clean off the dirty windows, headlights, tail
lights and the license plate.
- Perform a brake test (especially after driving through water).
A WARNING
- Be espec ially aware and attentive when
dr iv ing under diff icult conditions . Dam­
ages to the vehicle and injuries may oc­
cur when driving at an excess ively high
speed or with incorrect driving maneu­
vers.
Driving and environment 199
- Always adjust your speed and handling
to the roads, terrain, traff ic and weather
conditions. Drive especially slow if off­ road with low visibility.
- Please note that the wheels can spin and
the vehicle can break away when the ESC
Offroad Mode is switched off, especially
when the road is slippery .
- Driving stability is reduced in the ESC
Offroad mode .
® For the sake of the environment
Avoid harming the environment and take
nature into cons ideration.
(D Tips
Only drive where it is allowed and always
stay on the provided roads and paths.
Driver messages
Applies to vehicles : a ll road
There is only one right way to drive in difficult
conditions: slowly and with caution!
When dr iving offroad, observe the following:
... Never drive the vehicle i n terrain which is
not suitab le for the vehicle, or which ex­
ceeds your driv ing ski lls. Never take any un­
necessary risks!
... Drive slow ly and cautiously!
... Pay attention to the
ground clearance of
your vehicle! This may vary depending on the load and composition of the ground and
the environment. The driver is therefore re­
sponsible for deciding whether a veh icle can
handle a specific situation.
... Act ivate the
ESC -Offroad-Mode c::> page 188
as needed.
Difficult terrain
Never dr ive in areas that are not familiar to
you and drive slowly when offroad and be pre­
pared and expect the unexpected (e.g. pot­
holes, boulders, tree stumps, etc.)
To prevent the vehicle from bottoming and avo id damage to the underbody, you should
drive straight across severe bumps in the

Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a tra iler, p lease remember
that the addit ional load will affect durab ility,
economy and performance .
T railer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
F or this reason, a lways fo llow the operating
and driving instructions provided and use
common sense.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer we ight. The hitch must be suita­
b le for your veh icle and trailer and must be
mounted secure ly on t he veh icle's chassis at a
technically sound location . Use only a t railer
h itch w ith a removab le ball moun t. A lways
check with the tr ailer hitch man ufac tur er to
make sure that you are using the correct
hitch.
Do not use a bumper hitch.
T he hitc h must be installed in such a way that
it does not inte rfe re with the impac t-absorb­
i ng b umper syst em. No modifica tions should
be made to the vehicle exhaus t and b rake sys­
tems . From t ime to time, check that a ll hitch
mo unt ing bolt s remain securely fas tened.
W hen you are not tow ing a trailer, remove the
trai le r hi tch ball moun t. T h is prevents the
hi tch from causing damage sho uld your ve hi­
cle be str uck from be hind
¢ &. .
Trailer brakes
If yo ur tra iler is equ ipped w it h a braking sys­
tem, check to be su re that it conforms to a ll
r eg ulat io ns.
Trailer towin g 201
The trailer hyd ra ulic bra ke system must not be
direct ly connected to the vehicle's hydraulic
brake system
¢ &. .
Safety chains
Alw ays use s afety chains between your ve hicle
and t he tra ile r.
Trailer lights
Tra ile r lights m ust meet all reg ulations . Be
su re to check w ith your authorized Audi dealer
fo r c orrec t w iri ng, sw itches, and relays.
Mirrors
If you a re unable to see the traffic behind you
u sing the regula r outside m irrors, then you
must insta ll ext ended mir ro rs. It is important
t h at you
always have clea r vis io n to the rear .
.8, WARNING
- If a trai ler has elec trica l br ake s plea se
no te th at t hese bra kes are not activat ed
by the fa ctory -fit ted control unit -risk of
accident!
- After removing the t railer hi tch, do no t
s to re it in yo ur vehicle . In case of sudden
brak ing, the hitch could fly fo rward and
in ju re you or yo ur passenge rs .
Operating instructions
Maximum traile r we ight
-
A trai ler fo r you r vehicle is limited to a typical
class 1 or class 2 tra iler.

202 Trailer towing
Tire pressure
When towing a trailer, inflate the tires of your
vehicle to the cold tire pressure listed under
"Full load" on the label located on the driver's
side B-pillar (visible when the door is open).
Inflate trailer tires to trailer and tire manufac ­
turers' specifications.
Lights
The headlight settings should be checked with
the trailer attached before driving off. Check
to make sure both vehicle and trailer lights
are working properly.
Safety chains
Be sure trailer safety chains are properly con­
nected from the trailer to the hitch on the ve­
hicle. Leave enough slack in the chains to per­
mit turning corners. When you install safety
chains, make sure they will not drag on the road when you are driving.
The chains should cross under the trailer
tongue to prevent it from dropping in case of
separation from the hitch.
Driving instructions
Driving with a trailer always requires extra
care and consideration.
To obtain the best possible handling of vehicle
and trailer, please note the following:
.,. Do not tow a loaded trailer when your car it­
self is not loaded.
.,. Be especially careful when passing other
vehicles.
.,. Observe speed limits .
.,. Do not drive at the maximum permissible
speed.
.,. Always apply brakes early.
.,. Monitor the temperature gauge.
Weight distribution
Towing a loaded trailer with an empty car re­
sults in a highly unstable distribution of
weight . If this cannot be avoided, drive at very
low speeds only to avoid the risk of losing
steering control. A "balanced" rig is easier
to operate and con­
trol. This means that the tow vehicle should be loaded to the extent possible and permissi­
ble, while keeping the trailer as light as possi­
ble under the circumstances. Whenever possi­
ble, transfer some cargo to the luggage com ­
partment of the tow vehicle while observing
tongue load requirements and vehicle loading
considerations.
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the rig. Do not
drive at the maximum permissible speed. Re­
duce your speed even more if load, weather or
wind conditions are unfavorable -particularly
when going downhill.
Reduce vehicle speed
immediately if the trail­
er shows the slightest sign of swaying .
Do not
try to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds
for vehicles towing trailers are lower than for
regular vehicles .
Always apply brakes early. When driving downhill, shift into a lower gear to use the en ­
gine braking effect to slow the vehicle . Use of
the brakes alone can cause them to overheat
and fail.
Coolant temperature
The coolant temperature gauge c> page 10
must be observed carefully . If the needle
moves close to the upper end of the scale, re­
duce speed immediately and/or turn off the
air conditioner.
If the coolant temperature warning light •
in the instrument cluster starts flashing, pull
off the road, stop and let the engine
idle for
about two minutes to prevent heat build-up .
_& WARNING
Anyone not properly restrained in a mov­
ing vehicle is at a much greater risk in an
accident. Never let anyone ride in your car
who is not properly wearing the restraints
provided by Audi.

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
o page 275.
Trailer towin g 203
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.
