F ig. 189 Pe rmi tted ball posit io n of the traile r hi tch
Tr aile r to wing weights
With a f ac tor y-inst all ed or an a ft er ma rket trailer
h itch, the maximum permissib le trailer weight is
4,400 lbs (2,000 kg) . The maximum perm iss ible
unb raked trailer weight is 1,650 lbs (750 kg) .
These spec ificat ions apply when dr iv ing on roads
hav ing an incl ine of less tha n 12%.
Perm is sible tongue load
For best vehicle handling under these changed
conditions, adjust the trailer load so that the
tongue load is at the maxim um allowable or
slightly lower. You can get an approx imation of
the tongue load w ith a bathroom scale or you can
measure the load at a tr ucking company or
weighing station.
W ith a
fa ctor y-installed or an aftermarket trailer
h itch, t he maximum permissib le load on the ball
h itch may not exceed 440 lbs (200 kg).
It is rec
ommended to use the maximum permissible
load.
Trailer load di stribution
B e su re the load in the trailer is held securely in
p lace to prevent it from s hift ing fo rwa rd, back
ward or sideways.

Ball mount
The trailer hitch may only be used w ith suitable
ball mount and ball
c::> fig. 189 . Installat ion of
the hitch ball must be carr ied out in accordance
w ith the manufacturer 's inst ruct ions.

Engine cooling system
Towing a tra ile r makes t he engine work harder. It
is important that the cooling system's perform
ance is up to the additional load . Make sure that
the cooling system has enough fluid .
Tire pressure
When towing a t railer, inflate the ti res of your
vehicle to the cold tire pressure listed under "Full
l oad" on the tire press ure label. The tire pressure
l abel is located on the driver 's side B-pillar . In
flate tra iler tires to trailer and tire manufactur
ers' specifications.
Lights
The head light settings shou ld be checked with
the trailer attached before driving off. Check to
make s ure both vehicle and trailer lights are
working properly.
Safety chains
Be sure tra ile r safety cha ins a re properly connect
ed from the trailer to the hitch on the vehicle.
Leave enough slack in the chains to permit tu rn
i ng corners . When you install safety chains, make
s u re they will not drag on the road when you are
driv ing.
The chains should cross under the trai ler 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 veh icle
and t railer, p lease note the following:
.., Do not tow a loaded trai ler when your car itself
is not loaded.
.., Be especially care ful when passing other
vehicles .
.., Observe speed limits.
.., Do not drive at the maximum permissible
speed.
.., Always app ly brakes early.
.., Monitor the temperature gauge.

tires.
,&. WARNING -
-Only use tire/rim combina tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident could result.
-For technical reasons, it is not possible to use tires from oth
er vehicles - in some cases,
you cannot even use tires from the same vehicle model.
-Make sure that the tires you select have enough clearance
to the vehicle . Replacement
tires should not be chosen simply based on the nominal
size, because t ires with a dif
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of
an accident.
242
-Only use tires that are more
than 6 years old when abso
lutely necessary and drive
carefully when doing so .
-Do not use run-flat tires on your vehicle. Using them when not permitted can Lead to ve
hicle damage or accidents.
- If you install wheel covers on
the vehicle, make sure they al
low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.
Tire wear/damage

tor
Tire wear
Check the tires regularly for wear.
- Inflation pressure that is too Low
or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear. ..

This can especially have a nega
t ive effect on handling, on the
risk aquaplaning when driving
through water, when driving
through curves and when brak ing, which increases the risk of
an accident.

When the vehicle is partially load

Checking/correcting tire
pressure
.,.Check the tire pressure at least
once per month and also check it
before every long drive .
.,.Always check the tire pressure
when the tires are
cold. Do not
reduce the pressure if it increas
es when the tires are warm.
.,.Check the label¢
fig. 207 for
the correct tire pressure based
on vehicle load .
.,.Correct the tire pressure if nec
essary.
.,.Vehicles with Tire Pressure Mon
itoring System*: store the modi
fied tire pressure in the Infotain
ment system
¢ page 253 .
.,.Check the pressure in the spare
tire*. Always maintain the maxi mum temperature that is speci-
fied for the tire. ..,

A WARNING
Always adapt the tire pressure
to your driving style and vehicle load.
-Overloading can lead to loss of
vehicle control and increase the risk of an accident. Read
and follow the important safe
ty precautions in¢
page 246,
Tires and vehicle load limits.
-The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much. This increases the risk of an accident because it
can cause the tire to burst and result in loss of vehicle con
trol.
-Incorrect tire pressure in creases tire wear and has a
