Tire pressure
When tow ing a trailer, inflate the tires of your ve­
hicle 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 manufacturers'
specifications.
Lights
Check to make sure both vehicle and trailer lights
are working properly .
Safety chains
Be sure trailer safety cha ins are p roperly connect­
ed from the trailer to the hitch on the vehicle.
L eave enough slack in the chains to permit turn ­
ing 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 trai ler tongue
to prevent it from dropping in case of separation
from the hitch.
Adjusting the Audi drive select
Make su re the vehicle is on a level su rface before
h itching up the trailer and before adjusting the
tongue weight . The vehicle must be in
auto or
comfort driving mode and not raised

· 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 follow ing:
.,. Do not tow a loaded trailer when your car itself
is not loaded .
.,. Be especially carefu l when passing other
vehicles.
.,. Observe speed lim its .
.,. Do not drive at the maximum permissib le
speed.
.,. Always app ly brakes early .
.,. Monitor the temperature gauge.
Weight distribution
Towing a loaded trailer with an empty car results
i n a h ighly unstab le distribution of weight. If th is
cannot be avoided, dr ive at very low speeds only
to avoid the risk of losing steer ing control.
A "balanced" rig is easier to operate and control.
This means that the tow vehicle shou ld be loaded
to the extent possible and permissib le, w hile
k eep ing the traile r as light as possible under the
circumstances. Whenever possible, transfer
some ca rgo to the luggage compartment of the
tow vehicle while observing tongue load require­
ments and vehicle loading considerations.
Speed
The higher the speed, the more difficult it be­
comes for the driver to contro l the rig. Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or wind cond itions are unfavorab le -particular ly when
going downh ill.
Red uce vehicle speed
immediately if the trailer
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 trai lers are lower than for regular
vehicles.
Always apply brakes early. When driving dow n­
hill, shift i nto a lower gear to use the engine

braking effect to slow the vehicle. Use of the
brakes alone can cause them to overheat and fail.
Air suspension*
When driving with a trailer, activate the trailer
mode of the air suspension. Switch the air sus­
pension trailer mode on when you are towing a
trailer. This will limit the regulation by the air
suspension while driving. Select in the MMI:
ICARI function button > (Car)* systems control
button>
Vehicle settings> Air susp.: towing>
On.
Coolant temperature
The coolant temperature gauge c::> page 10 must
be observed carefully. The coolant temperature
can increase if you drive on long inclines in a low
gear at high engine speeds . Reduce your speed
immediately if the LEDs in the top part of the dis­
play turn on .
For more information about indicator lights, re­
fer to.
c::> page 15.
A WARNING
Anyone not properly restrained in a moving
vehicle is at a much greater risk in an acci­
dent . Never let anyone ride in your car who is
not properly wearing the restraints provided
by Audi.
Trailer mode notes
Important to know
-
Your vehicle handles differently when towing a trailer because of the additional weight and dif­
ferent weight distribution . Safety, performance
and economy will greatly depend on how careful­
ly you load your trailer and operate your rig.
Before you actually tow your trailer, practice
turning, stopping and backing up in an area away
from traffic . Keep practicing until you have be­
come completely familiar with the way your vehi­
cle-trailer combination behaves and responds.
Backing up is difficult and requires practice. Back­
ing up with a trailer generally requires steering
Trailer mode
action opposite to that when backing up your ve­
hicle without a trailer.
Maintain a greater distance between your vehicle
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 you cannot accel­
erate as fast as you normally would because of
the added load. Make sure you have enough room
to pass. After passing, allow plenty of room for
your trailer before changing lanes again.
Avoid jerky starts, sharp turns or rapid lane
changes.
(D Tips
- Do not tow a trailer during the break-in peri­
od of your vehicle.
- If you tow a trailer, your Audi may require
more frequent maintenance due to the ex­
tra load
c::> page 2 7 4.
Parking on a slope
Do not park on a slope with a trailer. If it cannot
be avoided, do so only after doing the following:
When parking:
" Apply the foot brake.
" Have someone place chocks under both the ve­
hicle 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 retrieve the wheel
chocks .

(D Tips
If you move the selector lever of the a utomat­
ic transmission to P be fore applying the par k­
ing brake and before block ing the wheels, you
may have to use more force later to move the
lever out of the P position .

Wheels
Your safety and that of your pas­
sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­
cle's
Gross Vehicle Weight Rating
("GVWR").
The "GVWR" includes the weight of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids
plus maximum load . The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of 150 lbs. (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any
luggage in the vehicle. If you tow
a trai ler, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load.
The
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper
limit to your vehicle's Gross Vehi -
246
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as
luggage.
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating
are listed on the safety compli­
ance sticker label located on the
driver's side B-pillar
c::> page 243,
fig. 197.
&_ WARNING ~
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and in­
crease the risk of the loss of
vehicle control.
-The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.

-Tires on a vehicle that has
been overloaded can fail sud­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
-Always make sure that the to ­
tal load being transported - including the weight of a trail­
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle heavier than the vehicle's
Gross Vehicle Weight Rating.
Determining correct load
limit
Use the example below to calcu­
late the total weight of the pas­
sengers and luggage or other
things that you plan to transport so that you can make sure that
your vehicle will not be overload­
ed.
Steps for Determining Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF OCCU­
PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle's placard
(tire inflation pressure label)
¢ page 243, fig. 19 7.
Wheels
2. Determine the combined
weight of the driver and pas­
sengers that will be riding in
your vehicle.
3. Subtract the combined weight
of the driver and passengers
from
"XXX" kilograms or "XXX"
pounds shown on the sticker
¢ page 243, fig . 197 .
4. The resulting figure equals the
available amount of cargo and
luggage load capacity. For ex­
ample, if the
"XXX" amount
equals
1400 lbs. and there will
be five
150 lbs. passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is 650 lbs .
(1400-750 (5 X 150) = 650
lbs.)
5. Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely ex­ ceed the available cargo and
luggage load capacity calculat ­
ed in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer
will be transferred to your vehi­
cle. Consult this manual to de­
termine how this reduces the ..,

off the road. T urn off the engine, turn the
emergency flashers on and use other warn­
ing devices to alert other mo torists.
- Make sure that passengers wait in a safe
place away from the vehicle and well away
from the road and traffic.
- T o help prevent the vehicle from moving
sudden ly and possibly slipping off the jack,
always fully set the parking brake and block
the wheel diagonally opposite the wheel be­ ing changed. When one front wheel is lifted
off the ground, placing the Automatic Trans­
mission in P (Park) will
not prevent the vehi­
cle from moving.
- Before you change a wheel, be sure the
ground is level and firm . If necessary, use a
stu rdy board under the jack.
- Always store the vehicle tool kit, the jack
and the replaced tir e in the luggage com­
partment ¢
