2016 AUDI A3 coolant

Driving
_& WARNING
- Never turn off the engine before the vehicle
has come to a complete stop. The full func­
tion of the brake booster and the power
steering is not guaranteed. You must use
more force to turn or brake if. Because you
cannot steer and brake as you usually
would, this could lead to accidents and seri­
ous injuries.
- Please note that the brake booster and pow­
er steering only work when the engine is
running. When the engine off, you must use
more force to steer or brake the vehicle. Be­
cause the usual steering and brak.ing capa­
bility is not available, the risk of accidents or
injuries increases .
- Always take the vehicle key with you when
leaving the vehicle, even for a short period
of time. This applies particularly when chil­
dren remain in the vehicle . Otherwise the
children could start the engine or operate
electrical equipment such as power win­
dows.
- For safety reasons, always park the vehicle
with the selector lever in the P position.
Otherwise, there is the risk that the vehicle
could roll.
- After the engine has been switched off, the
radiator fan can continue to run for up to 10
minutes -even with the ignition switched
off. It can also switch on again after some
time if the coolant temperature rises as the result of heat buildup or if the engine com­
partment is heated by the sun's rays and the
engine is hot.
(D Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after the engine is
switched off- there is a risk of damaging the
engine. For this reason, let the engine run for
at idle for approximately two minutes before
shutting it off.

specif ications.
Lights
Check to make sure both vehicle and t railer lights
are working p roper ly.
Safety chains
Be sure t railer safety chains are properly connect­
ed from the trai le r to the hi tch on the veh icle.
L eave enough sla ck in the cha ins to permi t turn­
ing corners. When yo u install safety chains, ma ke
sure they wi ll not drag on the road when yo u are
driving .
The cha ins s hou ld cross under the trailer tongue
t o prevent it from dropping in case of separation
from the h itch .
Driving instructions
Driving with a trailer always requires extra care
and consideration .
To obtain t he best poss ible handling of vehicle
and traile r, please note the fo llow ing :
.,. Do not tow a loaded trailer when your car itself
is not loaded.
.. Be especi ally ca ref ul when pass ing othe r
vehicles.
.. Observe speed limi ts .
.. Do not d rive at the maximum permissible
speed.
.. Always apply brakes early.
.. Monitor the temperature gauge .
Weight distribution
Towing a loaded t railer w ith an empty car res ults
in a high ly unstable distribution of weight . If this
cannot be avoided, drive at very low speeds on ly
to avoid the risk of losing steering control.
A "balanced" rig is easie r to operate and cont rol.
This means that the tow vehi cle should be loaded
to the extent possible and permissible, while
keep ing the tra iler as light as possib le under the
circumstances. Whenever possible, transfer
some cargo to the l uggage compartment of the
128
tow veh icle wh ile observing tong ue load require ­
ments and vehicle loading considerations.
Speed
The higher the speed, the mo re diff icu lt i t be­
comes for the driver to con trol the r ig. Do not
drive at t he maxim um permissible speed. Reduce
you r speed even more if load, weather or wind
con dit ions are unfavorab le - partic ularly when
go ing downh ill.
Reduce vehicle speed
immediately if the trailer
shows the slightest sign of swaying.
Do not try
to stop the swaying by accelerating.
Observe speed limi ts. In some areas, s peeds fo r
vehicles towing trailers are lower than for regular
vehicles .
A lways apply bra kes early. Whe n driving down­
hill, shift in to a lower gea r to use the engine
b raki ng effect to slow the vehi cle. Use of the
brakes alone ca n cause them to over heat and fai l.
Coolant temperature
The coolant temperature gauge 9 page 12 must
be obse rved caref ully. The coolant temperature
c a n incre ase if yo u drive o n long incl ines in a low
gear a t high engine speeds . Red uce your speed
immediately if the LE Ds in the top part of the dis­
play turn on .

A WARNING
-
Anyone not prope rly restrai ned in a moving
vehicle is at a much greate r risk in an acci ­
dent. Never let anyone ride in your car who is
not properly wear ing the restraints provided
by Aud i.
Trailer mode notes
Important to know
Your vehicle handles differen tly when towing a
trailer because o f the additiona l weight and di f­
ferent weight distribution. Safety, performance
and economy will g reatly depend on how caref ul-
l y you load your trai ler and operate you r rig. ..,_

Checking and Filling
CJ) Note
-Only use Ad Blue that conforms to the
standard ISO 22241-1. Do not mix any addi­
tives with the AdBlue and do not dilute it
with water.
- Only use refill bottles that are approved for your vehicle. Using other systems can cause Ad Blue to leak.
- Do not add Ad Blue to the diesel tank or add diesel fuel to the Ad Blue tank. Do not start
the engine under any circumstances if the
wrong fuel is filled in the tank . There is a
risk of damaging the fuel tank system and
the engine . See an authorized Audi dealer or
authorized Audi Service Facility for assis­
tance.
- AdBlue attacks surfaces such as painted ve­
hicle components, plastic and carpet. Re­
move the fluid as quickly as possible with a
damp cloth and plenty of cold water. If the
Ad Blue has already crystallized, use warm
water and a sponge. AdBlue residue that is
not removed will crystallize and can damage
the affected surface .
- Do not store the refill bottle in the vehicle.
If it leaks, the escaping Ad Blue could dam­
age the vehicle interior .
- Do not allow Ad Blue to come into contact
with clothing. If there is contact with the
fluid, flush immediately with plenty of wa ­
ter .
(D Tips
-You can obtain refill bottles from an author­
ized Audi dealer or authorized Audi Service
Facility .
- Follow the Ad Blue manufacturer's instruc­
tions for use and storage .
- A permitted refill bottle contains approxi­
mately 1.9 liters of AdBlue .
- Ad Blue can freeze at very low temperatures.
If this happens, the system will not detect
that the Ad Blue was refilled and it will con­
tinue to inform you of the low AdBlue level.
The message turns off as soon as the tank
thaws out again.

Engine compartment
Working in the engine compartment
Special care is required if you are working in the
engine compartment
For work in the engine compartment such as
checking and filling fluids, there is a risk of in­
jury, scalding, accidents, and burns. For this
reason, follow all the following listed warnings
and general safety precautions. The engine
compartment is a dangerous area.
¢ .&. .
.8, WARNING
To reduce the risk of injuries, complete the
following steps before opening the hood:
- Turn the engine off.
- Switch the ignition off.
- Set the parking brake.
- Place the selector lever in the P position.
- Let the engine cool down.
- Never open the hood when you see that
steam or coolant drips from the engine
compartment- there is a danger of burns!
Wait until no steam or coolant flows out.
- Keep children away from the engine com­
partment.
- Never spill fluids on a hot engine. These flu­
ids (such as the freeze protection contained in the coolant) can catch fire.
- Avoid short circuits in the electrical system,
especially the battery.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of personal injury.
- Never open the cap on the coolant expan­
sion tank when the engine is warm . The
cooling system is under pressure.
- To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
large cloth when opening.
- Do not remove the engine cover under any
circumstances . This increases the risk of
burns.
- If tests need to be performed with the en-
-
gine running, there is additional danger due ~
