200 Trailer towing
Trail er load dis tr ibut ion
Be sure the load in the trai ler is held securely
in place to prevent it from shifting forward,
backward or sideways.
N eve r all ow a p assenger to rid e in a trailer
~ .&. in Driving instructions on page 201.
Engine cooling sy stem
Towing a tra iler makes the eng ine work hard­
er . It is important that the cooling system's
performance is up to the addit ional load .
Make sure that the cooling system has eno ugh
flu id.
Tir e pressure
When tow ing a tra iler, inflate the t ires of your
vehicle to the co ld tire pressure listed under
" Full load" on the label loca ted o n the dr iver's
side B-pillar (v is ible when the door is open).
I nflate trailer tires to tra iler and tire manufac­
turers' specifications.
Lights
Check to make sure both veh icle and trailer
l ights are wor king p roperly.
Safe ty chain s
Be sure tra iler safety cha ins are properly con­
nected from the trailer to the hitch on the ve ­
h icle . Leave enough slack in the chains to per­
mit turning corners. When you install safety
cha ins, make sure they w ill not drag on the
road when yo u are driving.
The chains shou ld cross under the tra iler
tongue to prevent it from dropping in case of
separat ion from the hitch .
Adjusting the Audi drive select
Make sure the vehicle is on a level surface be­
for e
hitching up the tra iler and b efor e adjust ­
ing the tongue weight . The vehicle must be i n
auto or comfort driving mode and not raised
~ page 103, ~CD .
Make sure that the vehicle is lowered . In Info ­
tainment, select:
I CARI function button> Lo w­
e r
control button . If you must drive under poor road conditions,
you can raise the vehicle
afte r coupling the
trailer or
a fter adjust ing the tongue we ight
~ page 105.
(D Note
-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.
Driving instructions
Driving with a trailer always requires extra
core and consideration.
T o obtain the best possible hand ling of vehicle
and trailer, please note the fo llowing:
.. Do not tow a loaded t railer when you r ca r it­
self is not loaded .
.. Be especially carefu l when passing other ve ­
hicles .
.. Observe speed limits.
.. Do not drive at the maximum permissible
speed .
.. Always apply brakes early .
.. Monitor the temperature gauge .
Weight distribut ion
T owing a loaded trailer with an empty car re ­
s ul ts 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 keep ing the trailer as light as possi­
ble under the ci rcumstances. Whenever poss i­
ble, transfer some cargo to the luggage com­
partment of the tow vehicle while obse rv ing
tong ue load requi rements and vehicle load ing
considerations .
Speed
The higher the speed, the more d ifficu lt it be­
comes for the driver to control the rig. Do not
1111>

drive at the maximum permissible speed. Re­
duce your speed even more if load, weather or
wind condit ions are unfavorable -part icularly
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 .
A lways apply brakes early. When driving
downhill, shift into a lower gear to use the en­
gine braking effect to slow the vehicle . Use of
the brakes a lone can cause them to overheat
and fail.
Coolant temperature
The coolant temperature gauge c:> page 10
must be observed carefully. The coo lant tem­
perature can increase if you drive on long in ­
clines in a low gear at high engine speeds. Re­
duce your speed immed iate ly if the L EDs in
the top part of the display turn on.
F or more information about indicator lights,
refer to.
i::> page 15.
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 restra ints
provided by Aud i.
Trailer towing tips
Important to know
Your veh icle hand les different ly when tow ing
-
a trailer because of the addit ional weight and
d ifferent weight distribution . Safety, perform­
ance and economy will greatly depend on how
carefully you load your trailer and operate
your ng .
Before you actually tow your trailer, practice
turning, stopp ing and back ing up in an area
away from traffic. Keep practicing until you
Trailer towing 201
have become completely familiar with the way
your vehicle-trai ler combination behaves and
responds .
Backing up is difficult and requires practice .
Backing up with a t railer generally requires
steering action opposite to that when backing
up your vehicle without a tra iler.
Maintain a greater distance between your ve­
hicle and the one in front of you . You wi ll need
more room to stop. To compensate for the
trailer, you w ill need a larger than normal
turning rad ius.
When passing, remembe r that you cannot ac­
ce lerate as fast as you norma lly would be­
cause of the added load. Make sure you have
enough room to pass. After passing, allow 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
c:> page 280.
Parking on a slope
Do not park on a slope with a trailer. If it can­
not be avoided, do so only a~er doing the fol­
lowing:
When parking:
.,. App ly the foot brake.
.,. Have someone p lace 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 posit ion .
When restarting after parking:
.,. Apply the foot brake.

produces a "fan shaped spray ".
~ Do not hold the spray no zzle too close to
soft materia ls.
W hen clea ning the vehi cle w it h a powe r wash­
e r
always fo llow the operating instruc tions.
Cleaning and protec tion 205
This applies particu la rly to the operating
pre ssure and the spraying di stance. Keep a
distance from soft materia ls such as rubber
hoses or insulating material as we ll as sensors
and camera lenses.
Do not use a jet which sprays water in a direct
stream or one that has a rotating jet.
Water tempera ture sho uld no t exceed 140 ° F
(60 °().
A WARNING
N eve r wash t ires with a jet that sprays wa­
ter in a direct stream . T hi s could cause in ­
v isib le damage to the t ires and weaken
them, even i f the spray is from a re lative ly
long distance and for a sho rt time. Dam­
aged and weakened tires can fail and cause
accidents and personal i njury .

Have the battery checked when you take your
vehicle in for service. Yo u are well advised to
replace a battery that is older than 5 years .
W ith certa in types o f airbag deployment, the
battery is disconnec ted from the vehicle elec ­
trica l system for safety reasons
c::> &. in Re­
pair, care and disposal of the airbags on
page 156.
Disconn ecting the battery terminal s
Some vehicle functions (power w indow regu­
l ators, for example) are lost if the battery ter­
minals are disconnected . These functions have
to be re learned after the battery terminals are
connec ted again. To prevent this, the battery
should only be disconnected from the vehicle
e lectrical system when absolutely necessary
for repairs .
Vehicles not driven for long period s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo­
nents are gradually cu t back or switched off .
This reduces energy consumption and main ­
tains starting capability over a longer per iod
c::> page 192. Some of the convenience func­
tions may not operate, s uch as the inte rior
lights o r the power sea t adjustment . T he con­
ve nience fun ct ions wi ll be available again
when yo u switch on the ignition and start the
engine.
Winter operation
During the winter mont hs, ba ttery capaci ty
t ends to decrease as tempe rat ures d rop . Th is
is because more powe r is also consumed while
starting , and the headlights, rear window de ­
fogger, etc., are used more oft en.
Avoid unnecessary power cons umption, par­
ticularly in c ity t ra ff ic or when t raveling on ly
short distances. Let your a uthorized Audi
dealer check the capac ity of the vehicle bat ­
tery before winter sets inc::>
page 233. A well
charged battery w ill not only prevent starting
problems whe n the weather is cold, but will
also last longer .

For your safety, we recommend that you have
your authorized Audi dealer replace burned out bulbs for you.
It is becoming increas ingly more and more
d iff icu lt to replace vehicle light bulbs since in
many cases, other parts of the car must first
be removed before you are able to get to the
bu lb. This applies especially to the light bulbs
in the front of your car which you can on ly
reach through the engine compartment.
Sheet metal and bulb ho lders can have sharp
edges that can cause serious cuts, and parts must be correctly taken apart and then prop­
erly put back together to help prevent break­
age of parts and long term damage from wa­
ter that can enter housings that have not been properly resealed.
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for you, since your dealer has the proper tools,
the correct bulbs and the expertise.
Gas discharge lamps (Xenon lights):
Due to the high electrical voltage, have the
bulbs replaced by a qualified technician.
Headlights with Xenon light can be identified
by the high voltage sticker.
LED headlights * require no maintenance .
Please contact your authorized Audi dealer if a
bu lb needs to be replaced.
A WARNING
Contact with high-voltage components of
the electrical system and improper re­
placement of gas discharge (Xenon) head-
Fuses and bulbs
light bulbs can cause serious personal in­
jury and death.
- Xenon bulbs are pressurized and can ex­
plode when being changed.
- Changing Xenon lamps requires the spe­
cial tra ining, instructions and equip­
ment.
- On ly an authorized Audi dealer or other
qualified workshop should change the bulbs in gas discharge lamps .
A WARNING
There are parts with sharp edges on the
openings and on the bulb holders that can
cause serious cuts.
- If you are uncertain about what to do,
have the work performed by an author­
ized Audi dealer or other qualified work­
shop . Ser ious personal injury may result
from imprope rly performed wo rk.
Q) Tips
-If you must replace the light bulbs your­
self, always remember that the eng ine
compartment of any vehicle is a hazard­
ous area to work in. A lways read and
heed all WARNINGS
