204 Trailer towing
different weight distribution. Safety, perform ­
ance and economy wi ll greatly depend on how
carefu lly you load your trailer and operate
your rig.
Before you actually tow your trailer, practice
turning, stopping and backing up in a n area
away from traffic. Keep practicing until you
have become comp letely fam iliar with the way
your veh icle-trailer comb ination behaves and
responds.
Backing up is d iff icult and requires practice.
Backing up with a tra iler genera lly requires
steering action opposite to that when back ing
up your veh icle without a trailer.
Maintain a greater distance between your ve­
h icle and the one in front of you. You will need
more room to stop. To compensate for the
trailer, you will need a larger than normal
turning radius.
When passing, remember that yo u cannot ac ­
celerate as fast as you normally would be­
cause of the added load. Make sure you have
enough room to pass. After passing, allow
p lenty of room for your tra iler before chang­
ing lanes aga in.
Avoid jerky starts, sharp turns or rapid lane
changes.
(D Tips
- Do not tow a tra iler dur ing the break-in
period of you r vehicle.
- If you tow a trailer, your Audi may re­
quire more frequent maintenance due to
the ext ra 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:
Wh en park ing:
.. Apply the foot brake .
.. Have someone place chocks under both the
vehicle and the trailer wheels. ..
With chocks in place, slowly release the
brakes unti l the whee l chocks absorb the

.. App ly the parking brake.
.. Select the P selector lever posit ion.
When re starting afte r park ing :
.. App ly the foot brake.
.. Start the engine.
.. Select the D/S se lector lever position.

chocks .
@ Tips
If you move the selector leve r of the auto­
matic transmission to P befo re applying
the pa rking brake and before bloc king the
whee ls, you may h ave to use more force
la ter to move the lever out of the P posi­
tion .

~ If there was no Ad Blue left in the tank and a
range of
O mi (0 km) was displayed in the
instrument cluster, switch the ignition on
for about 15 seconds before starting the en­ gine.
_& WARNING
Ad Blue can irritate the skin, eyes and res­piratory system. If there is contact with
the fluid, flush immediately with plenty of
water. Consult a physician if necessary.
(D Note
- Only use Ad Blue that conforms to the standard ISO 22241-1. Do not mix any
additives with the Ad Blue and do not di­lute it with water .
- Do not add Ad Blue to the diesel tank or
add diesel fuel to the Ad Blue tank. Mix­
ing can lead to damage to the engine
and the Ad Blue tank system. Warranty
does not cover damage caused by this.
- AdBlue attacks surfaces such as painted
vehicle components, plastic and carpet.
Remove the fluid as quickly as possible
with a damp cloth and plenty of cold wa­
ter. If the Ad Blue has already crystal­ lized, 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 vehi­ cle. If it leaks, the escaping Ad Blue could
damage the vehicle interior.
- Do not allow AdBlue to come into con­
tact with clothing . If there is contact
with the fluid, flush immediately with
plenty of water.
@ Tips
- You can obtain refill bottles from an au­
thorized Audi dealer or authorized Audi

Checking and Filling 217
Hood
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
injury, scalding, accidents, and burns. For
this reason, follow all the following listed
warnings and general safety precautions.
The engine compartment is a dangerous
area.
c::> .&. .
_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
fluids (such as the freeze protection con­
tained in the coolant) can catch fire .
- Avoid short circuits in the electrical sys­
tem, especially the battery .
- When working in the engine compart­
ment, 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 ex­
pansion 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.

218 Check ing and F illin g
- Do not remove the engine cover under
any circumstances. Th is increases the
risk of burns.

nearby
- To reduce the r isk of electric sho ck a nd
injury, never touch the following compo­
nents when the engine is running or is
being started:
- Ignition cable
- Other components in the electronic
h igh voltage ignition system
- If you must check or perform work on
the engine while it is running:
- Set the parking brake and place these­
lector lever in the P (park) posit ion
first.
- Always proceed with ext reme caut ion
so that clothing, jewelry or long hair do not become ca ugh t in the radiator fan,
fan belt o r other moving components
or do not come into contact with hot
components . Tie back long hair before
beginning work and do not wear cloth­
ing that can hang down into the en­
g ine.
- Limit your exposure to exhaust and
chemica ls to as short a time as poss ible
