206 Trailer towing
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 follow 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 206, 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 vehicle's chassis at a
technically sound location . Use only a trailer
hitch with a removable ball mount. Always
check with the trailer 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
hitch from causing damage should your vehi
cle be struck from behind
c:::> A.
Trailer brakes
If your trailer is equipped with a brakin g 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 trailer for your vehicle is limited to a typical
class 1 or class 2 trailer.
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 208.
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.
Make sure that the cooling system has enough
fluid.
Tire pressure
When towing a trailer, inflate the tires of your
vehicle to the cold tire pressure listed under
"Full load" on the label located on the driver's
side B-pillar (visible when the door is open).
Inflate trailer tires to trailer and tire manufac
turers' specifications.
Lights
Check to make sure both vehicle and trailer
lights are working properly.
Safety chains
Be sure trailer safety chains are properly con
nected from the trailer to the hitch on the ve
hicle. Leave enough slack in the chains to per
mit turning corners . When you install safety
chains, make sure they will not drag on the
road when you are driving.
The chains should cross under the trailer
tongue to prevent it from dropping in case of
separation from the hitch.
Adjusting the Audi drive select
Make sure the vehicle is on a level surface be
fore hitching up the trailer and before adjust
ing the tongue weight. The vehicle must be in
auto or comfort driving mode and not raised
qpage 100, ~CD .
Make sure that the vehicle is lowered. In Info
tainment, select:
ICARI function button> Low
er
control button.
If you must drive under poor road conditions,
you can raise the vehicle
after coupling the
trailer or
after adjusting the tongue weight
qpage 102.
- Changes in temperature or load can af
fect the height of the vehicle .
- Always select
auto or comfort mode.
Otherwise, the tongue load specified for
your vehicle will no longer be applicable.
Trailer towing
Driving instructions
Driving with a trailer always requires extra
care and consideration .
To obtain the best possible handling of vehicle
and trailer, please note the following:
... Do not tow a loaded trailer when your car it
self is not loaded.
... Be especially careful when passing other
vehicles.
... Observe speed limits .
... Do not drive at the maximum permissible
speed.
... Always apply brakes early .
... Monitor the temperature gauge.
Weight distribution
Towing a loaded trailer with an empty car re
sults in a highly unstable distribution of
weight. If this cannot be avoided, drive at very
low speeds only to avoid the risk of losing
steering control.
A "balanced" rig is easier to operate and con
trol. This means that the tow vehicle should
be loaded to the extent possible and permissi
ble, while keeping the trailer as light as possi
ble under the circumstances. Whenever possi
ble, transfer some cargo to the luggage com
partment of the tow vehicle while observing
tongue load requirements and vehicle loading
considerations.
Speed
The higher the speed, the more difficult it be
comes for the driver to control the rig. Do not
drive at the maximum permissible speed. Re
duce your speed even more if load, weather or
wind conditions are unfavorable -particularly
when going downhill .
Reduce vehicle speed
immediately if the trail
er shows the slightest sign of swaying .
Do not
try to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds
for vehicles towing trailers are lower than for
regular vehicles . ..,..

208 Trailer towing
Always apply brakes early. When driving
downhill, shift into a lower gear to use the en
g ine braking effect to slow the vehicle . Use of
the brakes alone can cause them to overheat
and fail.
Coolant temperature
The coolant temperature gauge¢ page 11
must be observed carefully. The coolant tem
perature can increase if you drive on long in
clines in a low gear at high engine speeds. Re
duce your speed immediately if the LEDs in
the top part of the display turn on .
For more information about indicator lights,
refer to.
¢ page 17 .
A WARNING
Anyone not properly restrained in a mov
ing vehicle is at a much greater risk in an
accident . Never let anyone r ide in your car
who is not properly wear ing the restraints
provided by Aud i.
Trailer towing tips
Important to know
Your vehicle handles differently when towing
a trailer because of the additional weight and
different weight distribution . Safety, perform
ance and economy w ill greatly depend on how
carefully you load your trailer and operate
your rig .
Before you actually tow your trailer, practice
turn ing, stopp ing and back ing up in an area
away from traffic. Keep practicing until you
have become comp lete ly familiar with the way
your ve hicle-trai ler comb ination behaves and
responds.
Backing up is difficult and requires practice .
Backing up with a tra iler generally requi res
steering act ion opposite to that when backing
up your vehicle without a trailer.
Maintain a greater distance between your ve
hicle and the one in front of you. You will need
more room to stop. To compensate for the trailer, you wi
ll need a larger than normal
turning radius.
When passing, remember that you cannot ac
celerate as fast as you norma lly would be
cause of the added load. Make sure you have
enough room to pass . After passing, a llow
plenty of room for your trailer before chang
ing lanes again.
Avoid jerky starts , sharp turns or rapid lane
changes.
(D Tips
- Do not tow a trailer during the break-in
period of your vehicle.
- If you tow a trailer, your Audi may re
quire more frequent maintenance due to
the extra load ¢
page 283.
Parking on a slope
Do not park on o slope with a trailer. If it can
not be avoided, do so only after doing the fol
lowing:
When parking:
.,. App ly the foot brake .
.. Have someone place chocks under both the
vehicle and the trailer wheels.
.. With chocks in place, slowly release the
brakes until the wheel chocks absorb the
load .
.. Turn the wheels towards the curb.
.. Apply the parking brake.
.. Select the P selector lever position .
When restarting after parking:
.. Apply the foot brake.
.. Start the engine.
.. Select the D/S selector lever position .
.. Release the parking brake and slowly pull
out and away from the wheel chocks .
.,. Stop and have someone retr ieve the wheel
chocks .
Ill-
@ Tips
If you move the selector lever of the auto
mat ic transm ission to P before app lying
the parking brake and before blocking the
wheels, you may have to use more force later to move the lever out of the P posi
tion .

248 Tire s and whee ls
- Only when all tires on the vehicle are fi l
led to the correct pressure, the tire pres
sure monitoring* system can work cor rectly.
- The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the driver observe the specified tire pressure values
for the tires and the correct pressures for
the funct ion of the tire pressure mon itor
ing system*.
- Always inflate t ires to the recommended
and correct tire pressure before driving
off.
- Driv ing with under inflated ti res bend
more, letting them get too hot resu lting
in tread separation, sudden ti re fail ure
and loss of control.
- Excess ive speed and/overloading can
cause heat bui ld -up, sudden ti re fail ure
and loss of control.
- If the tire press ure is too low or too high,
the tires wi ll wear prematurely and the
vehicle will not hand le we ll.
- If the tire is not flat and you do not have
to change a wheel immediate ly, drive at
reduced speed to the nearest service sta
t ion to check the tire pressure and add
air as required.
Driving without va lve stem caps can cause
damage to the tire va lves. To prevent this,
always make sure that factory installed
valve stem caps on all wheels are securely mounted on the valve.
@) For the sake of the environment
Underinf lated tires will a lso increase the
fuel consumption.
Tires and vehicle load limits
There are limits to the amount of load or weight that any veh icle and any t ire ca n carry.
A veh icle that is overloaded w ill not handle
well and is more difficult to stop. Over load ing
can not on ly lead to loss of veh icle contro l, but can also damage important parts of the
vehicle and can lead to sudden tire fai lure, in
clud ing a b lowout and sudden deflation that
can cause the vehicle to crash.
Your safety and that of your passengers also depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and everything in and on the veh icle. These
load lim its are technically referred to as the
vehicle's
G ro ss Vehicl e We ight R ating
("GVWR").
The "GVWR" includes the weight of the basic
vehicle, all factory installed accessories, a full
tank of fuel, o il, coolant and other fluids plus
maximum load. The max imum load includes
the number of passengers that the vehicle is
intended to car ry ("seat ing capac ity") with an
ass umed we ight of 150 lbs (68 kg) for each
passenge r at a designated seating position
and the total weight of any luggage in the ve
hicle . If you tow a trai ler, the weight of the
trailer hitch and the tongue weight of the
loaded tra iler must be included as part of the
vehicle load.
The
G ro ss Axle We ight R ating ("GAWR") is
the maximum load that can be applied at each of the vehicle's two axles.
The Gross Vehicle Weight Rating and the Gross Axle Weight Rating are listed on the
safety comp liance sticker label located on the
driver's side B-pillar . Your Audi has 5 seat ing
pos itions, 2 in the front and 3 in the rear for
total seating capacity of 5 . Each seating posi
t ion has a safety belt
Q page 138, Safety
belts.
The fact that there is an upper limit to your
vehicle's Gross Vehicle Weight Rating means
that the total weight of whatever is being car
ried in the vehicle ( includ ing the weight of a
t ra ile r hi tch and the tongue weigh t of the
loaded tra iler) is lim ited. The more passen
gers in the vehicle or passengers who are
heavier than the standard weights assumed
mean that less weight can be carried as lug-
gage.

Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balan cing, correct tire pressure and driv
ing style.

Tire pressure
Incorrect t ire pressure causes premature wea r
and can cause sudde n tire blow-out . For this
reason, tire pressu re must be checked at least
o nce a month
¢ page 246 .
Driving style
Driving fast around c urves , heavy accelerat ion
and hard braking increase tire wear .
Rotating tires for more even wear
F or all four tires on your ve hicle to have the
same service life, we recomme nd that the
front and rear tires are rotated accord ing to
the tire manufact urer's suggested tire rota
tion intervals. Please remembe r th e follow
i ng:
- T ire rotation intervals may differ from the
veh icle service intervals o utli ned in your
Warranty
& M ain tena nce booklet.
- The longer one tire is used in one location
on t he vehicle, the more it wears at certain
points; the refore , we recommend that you
follow the tire man ufac turer's suggested
tir e rotat ion intervals.
- Ve hicles w ith front -wheel dr ive experience
more trea d wear on the fro nt wheels com

Using the spa re tire (compact spare tir e)
The compact spare tire is on ly intended for
emergencies until you can reach a repair shop .
Replace it as quick ly as poss ible with a stand
ard wheel and tire.
There are some restrictions on the use of the compact spare tire. The compact spare tire
has been designed specifically for your type of
veh icle. It must not be swapped with a com
pact spare t ire from another type of vehicle.
Snow chain s
For technical reasons, the use of snow chains
on the compact spare tire is
not permitted.
If you do have to dr ive w ith snow cha ins and a
front tire f ails, mount the spare whee l with
tire instead of a rear tire . Install the snow
chains on the rear tire and use it to replace
the defective front tire.
A WARNING
-Never use the spare tire if it is damaged
o r if it is worn down to the tread wear in
dicators .
- If the spare tire is more than 6 years o ld,
use it only in an emergency and w ith ex
treme caution and careful driving.
- The spare tire is intended only for tem
porary and short-term use. It should be
replaced as soon as possible w ith the
normal wheel and t ire.
- After mounting the compact spare tire,
the tire pressure must be checked as
soon as poss ible. The tire pressure of the
c ompact spare tire must be 4.2 bar; oth
erwise, you risk hav ing an accident .
- Do not drive faster than 50 mph (80 km/
h). You risk having an acc ident.
- Avoid fu ll-throttle acce le rat ion, heavy
braking, and fast corner ing . You risk hav
ing an acc iden t.
What do I do now? 263
- Never drive using more than one spare
wheel and tire. You r isk having an acci
dent .
- Normal summer or winter t ires must not
be mounted on the compact spare wheel
rim.
- For technical reasons, the use of tire
chains on the spare tire is not permitted .
If it is necessary to drive with t ire chains,
the spare wheel must be mounted on the
front axle in the event of a flat in a rear
tire. The newly available front wheel
m ust then be instal led i n place of the
rear whee l w ith the flat tire. Installing
the tire chain be fore mounting the whee l
and tire is recommended.
- Loose items in the passenger compart
ment can cause serious personal injury
during hard braking or in an accident. Never store the inflatable spare tire or
jack and tools in the passenger compart
ment.
