2014 AUDI A5 COUPE engine overheat

Instrument s and warning /indicator lights 11
A WARNING
- Always observe the warning in
c::> page 206 , before opening the hood
and checking the engine coolant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dripping from the engine compartment.
You could burn yourself. Let the engine
cool off first so that you cannot hear or
see any steam or engine coolant .
(D Note
-Mounting additional lights or accessories
in front of the air inlets reduces the cool­
ing effect of the rad iator. At high outside
temperatures or high eng ine load , the
engine could overheat.
- The front spoiler has been designed to
properly distribute the cooling air when
the veh icle is moving .
If the spoiler is
damaged , this cou ld reduce the cooling
effect and the engine co uld then over­
heat. Ask your authorized Aud i dealer for
assistance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
If engine RPM drops below 1,500, you should
downshift to the next lower gear . T he red area
at the end of the scale indicates maximum
perm issible engine RPM after the break-in pe­
riod. Before reaching this area, move these­
lector lever to position 0/5 or ease your foot
off the accelerator pedal.
@) Note
The tachometer needle@c::> page 10,
fig . 3 shou ld only briefly be in the red
zone: you could damage your engine! The
beg inning of the red zone varies depend-
ing on the engine .
@) For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise.

80 On the road
Warning threshold 2 can be set in the speed range starting from
20 mph to 150 mph (30
km/h to 240 km/h). Settings can each be ad­
justed in intervals of
6 mph (10 km/h).
Cruise control
Switching on
The cruise control system makes it possible to
drive at a constant speed starting at
20 mph
(30 km/h).

l:l
II (US model)/ B (Canadian mode l) are
shown in the display¢
fig. 81. The display
may vary, depending on the type of display in
your vehicle.
The speed is kept constant by modifying en­
g ine power or through an active brake inter­
vention.
A WARNING
-- Always pay attent ion to the traffic
around you when the cruise control is in
operation. You are always responsible for
your speed and the distance between
your veh icle and other vehicles.
- For reasons of safety, cruise control
should not be used in t he city, in stop­
and-go traffic, on twisting roads and
when road conditions are poor (such as
ice, fog, gravel, heavy rain and hydro­
p laning) -risk of accident .
- Turn off the cruise control temporarily
when entering turn lanes, highway exit
lanes or in constr uction zones .
- Please note that inadve rtently "resting"
your foot on the accelerator pedal causes the cruise control not to brake. This is
because the cruise control is overridden
by the driver's acceleration.
- If a brake system malfunction such as
overheating occurs when the cruise con­
trol system is switched on, the braking
function in the system may be sw itched
off. The other cruise control functions re­
main active as long as the indicator light
II (US models)/ ... (Canadian models)
is on.
(D Tips
-Veh icles with manual transmiss ion: You
can attain the set speed only if the gear
th at is cur rently engaged will allow it, or
if it does not tax the engine and allows it
to run smoothly. Therefore shift into a
hig her or lower gear in a timely manner.
- Th e brake lights illuminate as soon as
the brakes apply automatically.
Changing speed
.. To increase/decrease the speed in incre­
ments, tap the lever in the
0 10 direction
¢ page 80, fig. 80.
.. To increase/decrease the speed quickly, hold
the lever in the
0 10 d irect io n until the de -
sired speed is displayed . ..,.

pears
¢ page 88 when the clutch is
overloaded.
- 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 206. Otherwise, any increase in
engine speed may set the vehicle in mo­
tion, even with the park ing brake ap­
plied.
(D Note
- 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.
- Allowing 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.
@ Tips
For safety reasons, the park ing brake is re­
leased automatically only when the driv­
er's safety belt is engaged in the buckle.
Hill descent control
Applies to vehicles: with S tronic/tiptronic
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 transmi ssion 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 st ill be nec­
essary to adjust the speed with the brakes. Hill descent contro
l switches off once the de­
cline levels out or you press the accelerator
pedal.
On vehicles with the cruise control system*
¢ page 80, hill descent control is also activat­
ed 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 .
Manual shift program
Applies to vehicles: with S tronic/tiptron ic
Using the manual shift program you can

Homelink
Universal remote
control
Description
Applies to vehicles: with Home link
The HomeLink universal remote control can
be programmed with the remote control for
devices that are already present.
With 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 rep lace
three different 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
dividual 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 programming of the sensor must be performed before you are able to use sys­
tems with Homelink. If the system does not activate after performing the one-time pro­
gramming, check whether the system uses a rolling coder:!.>
page 118 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 requ ired 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.
Homelink 115
- 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, th is can overstrain motor and
damage its electrical components - an
overheated mo tor is a fire hazard!
- To avoid possib le injuries or property
damage, please always make abso lutely
certa in that no persons or objects are lo­
cated in the range of motion of any
equipment being operated.

ESC includes and/or works together with the
anti-lock brake system (ABS), brake assist sys ­
tem, anti -slip regulation (ASR) , e lectronic dif­
ferential lock (EDL), dynamic steering* and electronic i nteraxle differential lock* /selective
wheel torque control* . ESC is switched on all
the t ime. I n certain s ituations when you need
less traction, you can switch
off ASR by press­
i ng the button~~
page 182, fig. 153 or
~ page 182, fig. 154. Be sure to sw itch ASR
on again when you no longer need less trac­
tion.
Anti-lock b ra king s ystem (ABS)
ABS prevents the wheels from locking up
when braking. The vehicle can still be steered
even d uring hard brak ing . Apply ste ady p res­
sure to the brake pedal. Do not pump the ped­
a l. A pulsing in the brake peda l indicates t hat
the system is he lping you to brake the vehicle.
Brake assist system
The brake assist system can decrease bra king
d istance. It increases braking power when the
d river presses the brake pedal quick ly in emer­
gency situations . You must press and hold the
brake peda l until the situation is over. In
veh icles w ith adaptive cru ise contro l*, the
brake assist system is more sensit ive if the
d istance detected to the veh icle ahead is too
small.
Anti- slip regulati on (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road condit ions. This makes it eas ier to
start, accelerate and drive up hills.
Elect ronic diffe renti al lo ck (EDL )
The ED L brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or wheels if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h) .
In extreme cases, EDL automatica lly switches
off to help keep the brake on the braked whee l
from overheating. EDL w ill switch on again au-
Intellig ent technolog y 181
tomat ica lly when conditions have returned to
norma l.
Dynamic steering*
On vehicles with dynam ic steering*, ESC helps
stab il ize the s teer ing in crit ica l sit uat io ns.
Electronic interaxle differential lock* /
selective wheel torque control*
T he electronic i nteraxle differential lock (front
whee l dr ive) or the se lective whee l to rque
control (all-wheel dr ive) opera tes when dr iv­
ing thro ugh curves. The front wheel on the in­
side of the c urve or both whee ls on the inside
of the curve are braked selectively as needed .
This min imizes sliding in the front wheels and
allows for more precise driving through
cu rves . The applicable system may not acti­
vate when dr iv ing in wet or snowy conditions.
A WARNING
- ESC, ABS , ASR, EDL dynam ic steering*
a nd the elect ronic interaxle differential
loc k* /se lective wheel torque control*
cannot overcome the laws of physics .
This is especially important on slippery
or wet roads. If the systems begin acting
to stabilize your veh icle, yo u should im­
mediately change your speed to match
the road and traff ic conditions. Do not
let the increased safety provided by
these systems tempt you to take r isks.
Doing so will increase the risk of a loss of
veh icle contro l, col lision and ser ious per­
sonal injuries.
- Always adapt your speed to road, traffi c
and wea ther conditions. The risk of los­
ing contro l of the vehicle increases when
driving too fast, espec ially through
curves and on slippery or wet roads, and
when dr iv ing too close to vehicles up
ahead. ESC, ABS, the brake ass ist sys­
tem, ASR, EDL dynam ic steering* and the
electronic interaxle differentia l lock*/se­
lective whee l torque control* cannot p re-
vent co llisions . ..,.

A WARNING 1= ~
After driving through water, mud, slush, etc., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re­
store the full brak ing effect.
([) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through wate r.
@ Tips
- Check the depth of the water before dr iv­
i ng through it.
- Do not stop the veh icle, dr ive in reverse
or switch the engine off when driving
th rough water.
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep for you r vehi­
cle to drive th rough safely.
- Avoid dr iving through sa lt water because
i t can ca use corrosion.
Catalytic converter
It is very important that your emission con­
trol system (catalytic converter) is function ­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner.
11-Always use lead -free gaso line¢ page 201,
Fuel supply .
"'"Never run the tank down all the way to emp­
ty.
11-Never put too much motor oil in your engine
¢ page 211, ~ Adding engine oil .
11-Never try to push -or tow -start your veh icle .
The catalytic converter is an efficient "clean­ up" device built into the exhaust system of
the vehicle . The catalytic converter burns
many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere .
Drivin g and en vironm ent 18 9
The exclusive use of unleaded fuel is critically
important for the life of the catalytic convert­
er and proper f unct ion ing of the engine.
A WARNING
- The temperature of the exhaust system
is high, both when driving and after stop­
ping the eng ine.
- Never touch the exhaust tail pipes once
they have become hot. This could result in burns.
- Do not park or operate the vehicle in
areas where the hot exhaust system may
come in co ntact with dry grass, br ush,
fue l spill or other material wh ich can
cause a fire .
- Do not apply additional undercoating or
ru stp roof ing on or nea r the exhaust
manifold, exhaust pipes, cataly tic con­
ve rter or heat shield s. Dur ing driving, the
substance used for undercoating could
overheat and cause a fire.
(D Note
- Be aware that just o ne tank filling with
leaded fuel w ill already ser iously de­
grade the performance of the catalytic
converter .
- Do not exceed the cor rect engine oil level
¢ page 211.
-Do not drive until the f ue l t ank becomes
comple tely empty . The engine co uld m is ­
fire . Unburned fuel could also get into
the exhaust system and this co uld cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve­
hicle is mov ing.
- Do not continue to operate your vehicle
under these conditions, as othe rwise fuel
can reach the catalyt ic converter. Th is
cou ld result in overheating of the con­
verter, requir ing its replacement.
