2015 AUDI A7 tow

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 102, ~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 104.
- 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 . ..,..

210 Trailer towing
A lways 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.
Air su spen sion *
When driving with a trai ler, activate the trailer
mode of the air suspension. Switch the air
suspension trailer mode on when you are tow­
ing a trailer. This will limit the regulation by
the air suspens ion while driving. Select in the
MMI:
! CARI function button> (C ar)* sys te m s
control button > Vehicl e se tting s> Air s usp .:
t o wing > On .
Coolant t emperatur e
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 immed iate ly if the LEDs in
the top pa rt of the display turn on.
For more information about indicator lights,
refer to. ¢ page 16 .
A WARNING
Anyone not properly restrained in a mov­
ing veh icle is at a much greater risk in an
accident. Never let anyone r ide in your car
who is not prope rly wearing the restraints
provided by Audi .
Trailer towing tips
Important to know
Your vehicle handles differently when tow ing
-
a trailer because of the addit ional weight and
d ifferent weight dist ribution. Safety, perform­
ance and economy w ill greatly depend on how
carefu lly 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 letely familiar with the way your vehicle
-trailer combination behaves and
responds .
Backi ng up is diffic ult and requi res p ractice.
Backing up w ith a trailer generally req uires
steering action opposite to that when backing
up your vehicle without a trailer.
Maintai n a greater d ista nce between yo ur ve­
hicle and the one in fron t of yo u. You w ill 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 ac­ ce le rate as fast as you norma lly would be­
ca use 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 tu rns o r 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 294.
Parking on a slope
Do not park on a 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 choc ks unde r both the
vehicle and the trailer wheels.
.,. With chocks in place, slowly release the
brakes unt il the whee l chocks absorb the
load .
.,. Turn the whee ls towards the curb.
.,. Apply the parking brake.
.,. Select the P selector lever posit ion.
When re sta rting after p ark in g :
.,. App ly the foot brake .
.,. Start the engine.

load. The maximum load in­
cludes the number of passen­
gers that the vehicle is intend­
ed to carry ("seating capacity")
with an assumed weight of
150 lbs (68 kg) for each pas­
senger at a designated seating
position and the total weight of
any Luggage in the vehicle . If
you tow a trailer, the weight of
the trailer hitch and the tongue
weight of the loaded trailer
must be included as part of the
vehicle load .
The
Gr oss Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of
the vehicle's two axles.
The Gross Vehicle Weight Rat ­
ing and the Gross Axle Weight Rating are listed on the safety
compliance sticker label locat­
ed on the driver's side 8-pillar .
Your Audi has 4 seating posi ­
tions, 2 in the front and 2 in the rear for total seating capacity
of 4. In some vehicles there are
5 seating positions, 2 in the
front and 3 in the rear for total seating capacity of 5. Each seat­
ing position has a safety belt
¢ page 138, Safety belts.
The fact that there is an upper limit to your vehicle's Gross Ve­
hicle Weight Rating means that
the total weight of whatever is being carried in the vehicle (in ­
cluding the weight of a trailer
hitch and the tongue weight of
the loaded trailer) is limited .
The more passengers in the ve­ hicle or passengers who are
heavier than the standard
weights assumed 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 247, fig . 200 .
_& WARN ING -
Overloading a vehicle can
cause Loss of vehicle 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 ve­
hicle from handling properly

being loaded on the vehicle.
That weight may not safely
exceed the available cargo
and luggage load capacity
calculated in Step 4.
6. If your vehicle will be towing
a trailer, load from your trail­
er will be transferred to your
vehicle. Consult this manual
to determine how this re­ duces the available cargo
and luggage load capacity of
your vehicle.
.,.Check the tire sidewall
(¢ page 260, fig. 204) to de­
termine the designated load
rating for a specific tire.
Tire service life
The service life of tires depends
on a lot of different things in­
cluding proper installation and
balancing, correct tire pressure
and driving style.
Fig. 202 Tire tread: tread wear indi­
cators (TWI)
Fig. 203 Rotating tires for more even
wear
Tread Wear Indicator (TWI)
The original tires on your vehi­
cle have
1/16 inch (1.6 mm)
high "wear indicators"
¢ fig. 202 running across the
tread. Depending on the make,
there will be six to eight of
them evenly placed around the
tire. Marks on the tire sidewall (for example "TWI" or other
symbols) indicate the positions
of the tread wear indicators.
Worn tires must be replaced. Different figures may apply in
other countries
¢ .&. .
Tire pressure
Incorrect tire pressure causes
premature wear and can cause
sudden tire blow-out. For this
reason, tire press ure must be
checked at least once a month
