Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passen
ger transportation .
If you plan to tow a trailer, p lease remember
that the additional load will affect durability,
economy and performance .
Trailer towing not on ly places more stress on
the vehicle, it also calls for more concentra
tion from the driver.
For this reason, always fo llow the operating
and driving instructions provided and use
common sense.
@ Note
If you are going to tow a trai ler, you must
activate the trailer operation mode
c:::> page 204, Operating instructions.
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suita ble for your vehicle and trailer and must be
mounted securely on the veh icle's chassis at a
technically sound location . Use only a trailer
hitch with a removable ball mount. A lways
check with the trai ler hitch manufacturer to
make sure that you are using the cor rect
hitch.
Do not use a bumper hitch.
The hitch must be installed in such a way that
it does not interfere with the impact-absorb
ing bumper system. No modifications should
be made to the vehicle exhaust and brake sys
tems . From time to time, check that all hitch
mounting bolts remain securely fastened.
When you are not towing a trailer, remove the
trai ler hitch ball mount. This prevents the
h itch from causing damage should your veh i
cle be struck from behind
c:::> A .
Trailer brakes
If your trailer is equipped with a brak ing sys
tem, check to be sure that it conforms to all
regulations.
T he trailer hydraulic brake system must not be
directly connected to the vehicle's hydraulic
brake system .
Safety chains
Always use safety chains between your veh icle
and the trailer.
Trailer lights
Trailer lights must meet all regulations. Be
sure to check with your Audi dealer for correct
wiring, switches and relays.
Mirrors
If you are unable to see the traffic behind you
using the regular outside mirrors, then you
must install extended mirrors. It is important
that you
always have clear v is ion to the rear .
A WARNING
--
After removing the trailer hitch, do not
store it in your vehicle . In case of sudden
braking, the hitch could fly forward and in
jure you or your passengers.
Operating instructions
Maximum trailer weight
A tra ile r for your vehicle is limited to a typical
class 1 or class 2 tra ile r.
Trailer load distribution
Be sure the load in the trailer is held securely
in place to prevent it from shift ing forward,
backward or sideways.
Never allow a passenger to ride in a trailer
c:::> A in Driving instructions on page 206 .
Engine cooling system
Towing a trailer makes the engine work hard
er . It is important that the cooling system 's
performance is up to the additional load.

24 6 T ire s and whee ls
The correct tire pressure for the spare wheel is
located on a label on the driver's side B-pillar.
Because tec hnical changes may be made to
vehicle equ ipment dur ing the model year, a l
ways compare the tire size designation on the
tire pressure labe l on your vehicle with the
tires on your vehicle . Make sure that the tire
si ze information on the vehicle label is the
same as the si ze of the tires on the vehicle.
This is especially important if the vehicle be
longs to someone else or you bought the veh i
cle with different rims/tires or you bought the
vehicle as a p reviously owned vehicle.
Remember, your safety and that of your pas
sengers also depends on mak ing sure that
l oad limits are not exceeded. Vehicle load in
cludes everybody and everything in and on the
ve hicl e. These load limits are technically refer
red to as the vehicle's Gross Vehicle Weight
Rating ("GVWR") . The Gross Ax le Weight Rat
ing ("GAWR") is the maximum load that can
be applied at each of the veh icle's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance st icker labe l located on the
driver 's side B-p illar . The tire pressure label on
your Aud i lists the maximum combined
weight of all of the occupants and luggage or
o ther cargo that the vehicle can carry. For the
l ocation of the tire pressu re labe l
i=:> fig. 191.
A WARNING
Overloading a vehicle can cause loss of ve
hicle control, a cras h or other accident, se
r ious personal injury, and even death.
- Carrying more weight than yo ur vehicle
was designed to carry will prevent the
vehicle from handling properly and in
crease the risk of a loss of veh icle con
trol.
- The brakes on a veh icle that has been
overloaded may not be able to stop the
vehicle within a safe distance.
- Tires on a vehicle that has been overload
ed can fail suddenly causing loss of con
trol and a crash . -
Always make sure that the total load be
ing transported - including the weight of
a trailer hitch and the tongue we ight of a
loaded trailer -does not make the vehi
cle heavier than the vehicle's G ross Vehi
cle Weight Rating.
A WARNING
-- I ncorrect tire pressures and/or underin-
flation can lead to a serious or fatal acci
dent.
- I nco rrect tire pressures and/or underin
flation cause increased ti re wear and can
affec t the handling of the vehicle .
- I nco rrect tire pressures and/or underin
flation can a lso lead to s udden t ire fail
ure, including a blowou t and sudden de
flation, ca using loss of veh icle cont ro l.
Checking tire pressure
The correct tire pressure for the tires original
ly installed on your vehicle is listed on the tire
pressur e label located on driver's side 8-pil
lar .
The recommended tire pressures are on the
t ir e pressure label and in the table
i=:> page 244, Cold tire inflation pressure.This
means that the pressure m ust be checked and
adjusted when the t ire has not been dr iven for
more than a couple of miles (kilometers) at
low speeds during the previous three hours.
Air in the tires expands when the tire heats up as a result of inter nal frict ion as it flexes in
u se . T he t ire pressure is higher when the tire
has warmed up t han whe n it is "co ld. "
It is the inflation pressure in a "co ld" t ire that
counts . The refore, you should never let a ir out
of a wa rm tire to match "Cold t ire inflat ion
pressure" recomme ndat ions
i=:, page 244 . The
t ir es wo uld then be unde rinflated and co uld
fail suddenly .
T he t ire pressure label on your Audi lists the
recommended co ld tire inflation pressures at
m aximum cap acity for the new, or ig inal
equipmen t tires tha t were on your vehicle at ..,.

2 78 Emergency situations
@ Tips
Check carefully to make sure the hook-up
is secure before moving the car up the flat
bed truck ramp.
Vehicle transport
Whenever you have your vehicle transported,
be sure to note the following:
(D Note
Mount the tie-down chains/cables over the
running surface (circumference) of the
tires. Never secure the vehicle by the axle,
the suspension struts or the front or rear
towline eye. For technical reasons, the
pressure in the suspension struts may
change during the transport and this will
adversely affect vehicle handling.
Lifting vehicle
Lifting with workshop hoist and with
floor jack
The vehicle may only be lifted at the lifting
points illustrated.

A WARNING
-To reduce the risk of ser ious injury and
veh icle damage.
- Always lift the vehicle only at the spe
cial workshop hoist and floor jack lift
points illustrated

Gros s Axle W eight Rating
The G ross Axle Weight Rating is the maximum
l oad tha t can be applied at each axle of the
vehicle
q .&. .
Vehicle capacit y weight
The vehicle capac ity we ight (max. load) is list
ed either on the dr iver's side B-pillar or inside
the fuel filler flap.
Roof weight
The max imum perm issible roof weight is
220 lb (100 kg ). The roof weight is made up
of the weight of the roof rack system and the
weight of the object be ing transported
q page 60, Loading the roof rack .
.&, WARNING
- T he ac tual Gross Axle Weight Rat ing at
the front and rear axles shou ld not ex
ceed the permiss ible weights, and their
combination must not exceed the Gross
Vehicle Weight Rat ing .
- Exceeding permissib le weight ratings can
result in vehicle damage, accidents and
personal injury.
CD Note
- The vehicle capacity weight figures apply
when the load is distributed evenly in the
vehicle (passengers and luggage). When
transporting a heavy load in the luggage
compartment, carry the load as near to
the rear axle as possib le so that the veh i
cle's handling is not impa ired.
- Do not exceed the maximum permissible
axle loads or the max imum gross vehicle
weight. Always remember that the vehi
cle's handling will be affected by the ex
tra load. Therefore, adjust you r speed ac
cord ingly.
- Always observe loca l regu lations.
