overheating AUDI Q3 2016 Owners Manual

Automatic transmission
Shifting with the shift paddle s*
You can operate the shift padd les in the D, Sor M
selector lever posit ions.
• To sh ift up one gear, tap the
0 shift paddle
¢fig. 93.
• To shift down one gea r, tap the O sh ift paddle.
• If you do not press a shift button within a short
time whi le in the D/S position, the transmission
will return to automatic mode. To keep shifting
using the shift buttons, move the selector lever
to the right out of the D/S position.
The transmission automatically shifts up or down
before critical engine speed is reached.
The transm ission only a llows manual shift ing
when the engine speed is within the permitted
range.
@ Tips
- When you shift into the next lower gear, the
transmission wi ll downshift only when there
is no possibility of over-revving the engine.
- When the kick-down comes on, the trans ­
mission will shift down to a lower gear, de­
pending on vehicle and engine speeds.
- Tiptronic is inoperative when the transmis­
sion is in the fai l-safe mode .
Kick-down
Kick-down enables maximum acceleration.
When you press the accelerator peda l down be­
yond the resistance point (called kick-down), the
automatic transmission downshifts into a lower
gear, depending on vehicle speed and engine RPM. It shifts up into the next higher gear once
the maximum specified engine RPM is reached.
A WARNING
Please note that the wheels could spin on
slick or slippery roads when kick-down is ac­
tive.
Transmission malfunction
• Transmission overheating! Please stop the
vehicle!
86
The transmission is too hot and can become dam­
aged. Stop and let the transmission coo l with the
engine running (at idle) in the P se lector lever po­
sition. Then the indicator light and the message
turn off, drive to an authorized Audi dealer or au­
thorized Audi Service Facility immediately to have
the malfunct ion corrected.
If the indicator light
and the driver message do not turn off, do not
continue driving. See an authorized Audi dea ler
or authorized Audi Service Facility fo r assistance.
Selector lever emergency release
In order to tow a vehicle due to power failure,
the selector lever emergency release must be ac­
tivated .

Fig. 95 Selector lever: emergency release
The emergency release mechanism is located in
the right area under the selector lever shift gate.
Using the emergency release can be complicated .
We recommend contacting an authorized Audi
dealer or authorized Audi Service Facility for as­
s istance, if necessary.
A maintenance tool from the vehicle tool kit
must be used to release

Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating .
11-Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are acceler­ ating . If you anticipate what is going to happen
next, you will need to brake less and, thus, accel­
erate less . Let the vehicle coast whenever possi­
ble - for example when you see that the next traf ­
f ic light is red .
Avoid full throttle
Driving a t modera te speeds saves fuel and im­
proves your mileage .
11-Try and keep well be low your car's max imum
speed.
Accelerating gent ly reduces fuel consumption,
engine wear, and does not disturb the environ ­
ment.
F ue l cons umption, exha ust emissions and engine
noise increase disproportionately at high speeds.
If you drive at approximately three quarters of
top speed, fuel consumpt ion will be reduced by
one half. Never drive faster than the posted
speed limit and weather conditions permit.
Reducing unnecessary idling
Even when your car is just idling i t burns up fuel.
11-S hut the engine off w hen you are not driving
the vehicle.
11-Do not warm up the vehicle by letting the en-
gine ru n at idle .
It makes sense to shut off the eng ine in traffic
jams, when wa iting for trains to pass at rai lroad
crossings, or at traffic lights that have long waits
on red . Turn ing the eng ine off for just 30 -40 sec ­
onds saves more fue l than is bu rned starting the
engine agai n.
It takes a long t ime for the engine to warm up
fu lly when it is runni ng at idle . However, wear
and noxious emiss ions are especially high when
the eng ine is wa rm ing up . So you should d rive
Driving and the envir onment
away as soon as you start the eng ine and avoid
running at high rpms w hil e the engine is sti ll
warming up .
(D Note
Do not leave eng ine idling una ttended after
starting. If wa rning lights shou ld come on to
i ndicate improper operation, they would go
unheeded. Extended idling also prod uces
heat, which could result in overheating or
other damage to the vehicle or other proper ­
ty .
Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel .
11-Have your vehicle serviced at regular interva ls.
By having your vehicle regular ly serv iced by an
authorized Audi dea ler helps to ensure that it
runs properly and economically. The cond ition of
your vehicle not only affects its safety and ability
to hold its value, it also affects
fuel con sump­
tion .
Chec k your oil each t ime you fill your tank.
T he amount o f oi l used is related to engine load
and speed.
It is normal fo r the oil consump tion of a new en­
gine to reach its lowest value after a ce rtain m ile­
age has been dr iven.
You m ust dr ive your ve hicle about 3,000 m iles
(5,000 kilometers) befo re yo u can prope rly as­
sess oil consumpt io n.
T h is also app lies to fuel consumption and eng ine
output.

tions i n your Warranty

le t. La ck of prope r maintenan ce as we ll as
imp roper use of the ve hicle will im pair the

Cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from freezing in the winter .
The cooling system is sealed and generally re­
quires little attention.
T he cooling system has been filled at the factory
with a permanent coolant which does not need to
be changed . The coolant consists of a mixture of
specially condit ioned water and the manufactur ­
er's glycol-basedcoolant add itive G 13 antifreeze
with anticorrosion additives (SO% for USA mod­
e ls; 60% for Canada models) . This mixt ure bot h
assures the necessary frost protec tion and pro­
tects meta l components in the engine's cooling
system from corrosion and scaling . It also raises
the boiling point of the coolant.
D o not red uce the concent ration of the coolant in
the summer by add ing p la in water.
The propor­
tion of coolant addit ive mu st be at least 50 %
but not more than 60 %
to mainta in antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant could
freeze and damage the vehicle heating and en­
g ine cooling system .
For year-round driving, antifree ze is added at the
factory for temperatures down to :
- -31° F(- 3S°C)USA
- -4 0 ° F ( - 40 °C) Can ada.
If you must add coolant, use a m ixture of water
and coolant addit ive. M ixing the coolant additive
with d istilled water is recommended .
_& WARNING
Before you check anythi ng i n t he engine com­
partment, a lways read and heed a ll WARN ­
INGS
¢ .&. in Working in the engine compart­
ment on page 177 .
(D Note
-Befo re winter se ts in, have the coo lant
checked to see if the coolant additive in you r
vehicle is sufficient to meet the cl imate con -
Check ing and Filling
ditions. This is especially important if you
live in a region where the winter is extreme­
ly cold. If necessary, increase the proportion
of coolant additive to 60%.
- When adding coolant additive to your cool­
ing system, remember :
- We recommend us ing only coolant add i­
tive G12+ + or G13 fo r yo ur vehicle. This
coolant addit ive is avai lab le a t aut horized
A udi dealers . O ther types of antifree ze can
significantly reduce corrosion pro tect ion .
The resulting corrosion can cause a loss of
coolant and serious engine damage.
- Do not add any type of radiator leak sealant
to your vehicle's engine coolant. Adding ra ­
diator repair fluid may adversely affect the
function and performance of your cooling system and cou ld resu lt in damage not cov­
ered by your New Veh icle Limited Warra nty .
Checking the engine coolant level
The engine coolant level can be checked with a
quick glance.
