2013 AUDI A8 trailer

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
immediatel y 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 app ly 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. ~
page 16.
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, stopping and backing up in an area
away from traffic. Keep practicing until you
Trailer towing 213
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 radius.
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

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.

214 Trailer towing
• Start the engine.
• Se lect the D selector lever position.
• Re lease the park ing 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 auto­ mat ic transm ission to P before app lying
the park ing brake and before blocking the
wheels, you may have to use more force later to move the lever out of the P posi­
tion.

The correct tire pressure for the spare wheel is
l ocated on a label on the driver's side B-pillar.
Because tec hnical changes may be made to
veh icle equ ipment dur ing the model yea r, a l­
ways compare the tire size designation on the
tire pressure label on your vehicle wit h the
tires on your vehicle . Make s ure that the tire
size information on the veh icle label is the
same as the s ize of the t ires 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 boug ht the
ve hicle as a previously owned vehicle.
Remember, your safety and that of your pas­
sengers also depends on mak ing su re that
l oad l imits are not exceeded. Vehicle load in­
cludes everybody and everything in and on the
veh icle. 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 app lied at each of the veh icle's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle We ight Rating are listed on the
safety compliance st icker label located on the
driver's side B-p illar . The t ire pressure label on
your Aud i lists the maximum combined
weight of a ll of the occupants and luggage or
other cargo that the vehicle can carry. For the
l ocat ion of the tire pressure labe l
c;, fig. 204.
A WARNING
Overloading a vehicle can cause loss of ve­
hicle control, a crash or other accident, se­
rious personal injury, and even death.
- Car rying 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
t rol and a crash.
Tire s an d wheel s 255
-Always make sure that the total load be­
ing transported - includ ing 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 Gross Vehi­
cle Weight Rating.
A WARNING
- Inco rrect tire pressures and/or underin­
flation can lead to a ser ious or fatal acci­
dent.
- Inco rrect tire pressures and/or underin­
flation cause increased tire wear and can
affect the handling of the vehicle.
- Inco rrect tire pressures and/or underin­
flation can a lso lead to sudden t ire fail­
ure, including a blowou t and sudden de­
flation, caus ing loss of veh icle contro l.
Checking tire pressure
The correct tire pressure for the tires original­
ly installed on your vehicle is listed on the tire
pressvre label located on driver's side 8-pil ­
lar.
T he recommended tire pressures are on the
ti re pressure label and in the table
c;, page 253, Cold tire inflation pressure .This
means that the pressure m ust be checked and
adjusted when the tire 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 internal frict ion as it flexes in
use. The tire pressure is h igher when the tire
has warmed up t han when it is "cold."
It is the inflation pressure in a "cold" t ire that
counts. Therefore, you should never let a ir out
of a warm tire to match "Cold t ire inflat ion
pressure" recommendat io ns
c;, page 253 . The
ti res wo uld then be unde rinfl ated and co uld
fail suddenly.
T he tire pressure label on your Audi lists the
recommended co ld tire inflation pressures at
max imum capacity for the new, or ig inal
equipment tires that were on your vehi cle at

258 Tires and wheels
mean that less weight can be carried as
luggage.
The tire pressure label on your Audi also lists
the maximum combined weight of all of the
occupants and luggage or other cargo that
the vehicle can carry. For the location of the
label ¢
page 253, fig. 204.
.&_ WARNING
Overloading a vehicle can cause loss of ve­
hicle control, a crash or other accident, se­
rious personal 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 con­
trol.
- 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 overload­
ed can fail suddenly, including a blowout
and sudden deflation, causing loss of
control and a crash.
- Always make sure that the total load be­
ing transported -including the weight of
a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehi­
cle heavier than the vehicle's Gross Vehi­
cle Weight Rating.
Determining correct load limit
Use the example below to cal­
culate the total weight of the
passengers and luggage or oth­
er things that you plan to trans­
port so that you can make sure
that your vehicle will not be overloaded.
Steps for Determining
Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF QC­
CU PANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX LBS" on your ve­
hicle's placard (tire inflation
pressure label)¢
page 253,
fig. 204.
2. Determine the combined
weight of the driver and pas­sengers that will be riding in
your vehicle.
3. Subtract the combined
weight of the driver and pas­
sengers from "XXX" kilo­
grams or "XXX" pounds
shown on the sticker
¢ page 253, fig. 204.
4. The resulting figure equals the available amount of car­go and luggage load capaci­
ty. For example, if the "XXX"
amount equals 1400 lbs.
and there will be five 150 lbs. passengers in your vehi­
cle, the amount of available
cargo and luggage load ca­
pacity is 650 lbs. (1400-7 50
(5
X 150) = 650 lbs.)
5. Determine the combined weight of luggage and cargo ..,

Spare wheel
Applies to vehicles: with spare wheel
The spare wheel is stored in the wheel well
underneath the floor panel in the luggage
compartment.

Changing a wheel
Before changing a wheel
Observe the following precautions for your
own and your passenger's safety when chang­
ing a wheel.
• After you experience a tire failure, pull the
car well away from mov ing traffic and try to
reach
le vel ground before you stop c:> ,&.
• All passengers should leave the car and
move to a safe location (for ins tance, behind
t he guardra il)
c:> ,& .
• Engage the parking brak e to prevent your
vehicle from rolling unintentionally
c:> ,& .
• Move sele ctor lever to po sit ion Pc:> &_ .
• If you are towing a trailer, unhitch the trail­
er from your vehicle.
• Take the
jack and the spare tire out of the
luggage compartment
