If luggage or cargo is to be ca rr ied on the roof,
you m ust observe the fo llow ing:
- On ly a specially designed roof rack may be used
on you r vehicle. These roof racks are the bas is
for a comple te roof rack system. Additional at­
t achments/ca rrier systems are necessary to
transpo rt luggage and spo rts equipment. We
recommend roof racks and attachments from
the Audi Genuine Accessories program.
- When installing the roo f rack, make sure that it
is mounted only at the designated points on
the roof
c::> fig. 88 or c::> fig. 89.
- The max imum permissib le roof load for your
vehicle is 200 lbs (90 kg). The roof load is the
total of the weight of the roof rack, the attach­
ments and the cargo you are carrying. However,
please note the permissib le load of the carrier
system being used, the permissible axle loads
and the permissible total vehicle weight
c::> page 3 79.
.&_ WARNING
- Follow the install ation instru ct ions prov ided
w ith the roof rack system.
If you do not se­
cure the roof rack system and objects on the
roof correctly, they could come loose from
the vehicle and ca use an accident.
- The risk of an accident increases when using
a roof rack system, because it changes the
driving characterist ics by shifting the center
of grav ity and/or the increasing the surface
area exposed to wind. Adapt your driving
and speed to the current cond itions.

engaged, for example when you notice that the next traffic light is red . This produces an engine
braking effect, which helps to protect the brakes
and tires and reduces the emissions and fuel con ­
sumpt ion to zero (fuel shut-off dur ing decelera­
tion) .
Shift efficiently
Upshifting earlier is an effective way to save fuel.
Staying in a gear too long uses fuel unnecessari­
ly.
Applies to: vehicles with manual transmission
Shift as soon as possible from first to second
gear. S hifting to the next highest gear at approxi­
mately 2,000 RPMs if poss ible is recommended.
Applies to: vehicles with automatic transmissions
Press down on the acce le rator peda l slowly and
avoid "kick -down".
Avoid full acceleration
You should rarely travel at the maximum vehicle
speed. High speeds cause a disproportionately
high increase in fuel consumption, emissions and
traffic noise. Driving more slowly saves fuel.
Reduce idling time
The Start/Stop system* he lps to reduce the idling
time automatically. In vehicles without the Start/
Stop system*, it is efficient to switch the engine
off when stopped at railroad cross ings and long
r ed lights. Stopping the engine for 30-40 sec­
onds already saves more fuel than the amount of
extra fuel needed to restart the eng ine.
It takes a very long time in idle to warm the en­
g ine up to operating temperature. Wear and
emissions are especially h igh in the wa rm-up
phase . Therefore, you should begi n driving im­
mediately a fter starting the engine . Avoid high
RPMs while do ing this .
Have maintenance performed regularly
By having maintenance performed regu larly on
your veh icle, yo u ca n he lp to reduce f uel con­
sumption before yo u even start to drive. The
maintenance condition of your vehicle not only
affects traffic safety and long-term value but a l-
Driving
so impacts fuel consumption . A poorly main ­
tained engine can lead to fuel consumption that is 10% higher than norma l.
Avoid short trips
The eng ine and exhaust cleaning system must
reach their optimal operat ing temperatu re to ef­
f ectively reduce consumption and emissions.
A cold engine uses a disproportionately high
amount of fue l. The engine reaches operating
temperat ure and consumption normalizes on ly
after approximate ly 2.5 miles (4 km).
Check the tire pressure
To save fuel, make sure the tires are always in­
flated to the correct press ure
~ page 344. The
fuel consumption can increase by 5% if the pres­
s u re is only 0.5 bar too low. Due to the increased
rolling resistance, low tire pressures wi ll also
l ead to greater tire wear and will affect driving
behavior.
Do not drive on winter tires year-round, as this
will consume up to 10% more fuel.
Eliminate unnecessary weight
S in ce eve ry po und of ext ra weight increases f uel
consumption , a quick inspection of the luggage
compartment may be worth it to avoid unneces ­
sary weight .
When not be ing used , a roof rack should be re­
moved to decrease the wind resistance of the ve­
hicle. This will save you approximately 12% fuel
at speeds from 62 -75 mph (100 - 120 km/h) .
Save energy
The eng ine drives the generator, which generates
electric ity; the fuel consumpt io n also incr eases
with the demand for electr icity. The refore, switch
electrical eq uipment off when you no longer
need it . Examples of equipment that uses a lo t of
energy are air blowers at a high setting, the rear
window defogger and seat heating* .
@ Note
Do not leave engine idling unattended after
starting. If warning lights shou ld come on to
indicate improper operation, they would go

Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation .
If you plan to tow a trailer, please remember that
the additional load will affect durability, econo­ my and performance.
Trailer towing not only places more stress on the
vehicle, it also calls for more concentration from
the driver.
For this reason, always follow the operating and
driving instructions provided and use common
sense.
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suitable
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 re­
movable ball mount . Always check with the trail­
er hitch manufacturer to make sure that you are
using the correct hitch.
Do not use a bumper hitch.
The hitch must be installed in such a way that it
does not interfere with the impact -absorbing
bumper system. No modifications should be
made to the vehicle exhaust and brake systems .
From time to time, check that all hitch mounting
bo lts remain securely fastened.
When you are not towing a trailer,
remove the
tra iler hitch ball mount . This prevents the hitch
from causing damage shou ld your vehicle be
struck from beh ind ¢
,&. .
Trailer brakes
If your trailer is equipped with a braking system,
check to be sure that it conforms to all regula­
tions .
Trailer towing
The trailer hydraulic brake system must not be
directly connected to the vehicle's hydraulic
brake
system ¢.&. .
Safety chains
Always use safety chains between your vehicle
and the trailer.
Trailer lights
T ra iler lights must meet all regulations . Be sure
to check w ith your author ized Audi dealer for cor­
rect wiring, switches and relays.
Mirrors
If you are unable to see the traffic behind you us­
ing the regular outside mirrors, then you
must in­
stall extended mirrors. It is important that you
always have clear vision to the rear.
,8. WARNING
After removing the traile r hitch, do not store
it in your vehicle. In case of sudden braking,
the hitch could fly forward and injure 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 shifting forward, back­
ward or sideways.
Never allow a passenger to ride in a trailer ¢.&.
in Driver messages on page 100 .
Engine cooling system
Towing a trailer makes the engine work harder. It
is important that the cooling system's perform ­
ance 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 tire pressure listed under "Full
load" on the label ¢ page 344. Inflate trailer

tires to tra iler and tire manufacturers ' specifica­
tions.
Lights
The headlig ht settings should be chec ked with
the t railer at tached before d riving off. Check to
make su re both vehicle and trailer lights are
wo rking properly.
Safety chains
Be sure t railer safety chains are properly connect­
ed from the trai le r to the h itch on the veh icle.
L eave enough sla ck in the c ha ins to permi t turn­
ing corners . When you install safety chains, ma ke
sure they wi ll not drag on the road when yo u are
driv ing .
The cha ins shou ld cross u nder the trailer tongue
to prevent it from dropp ing in case of separation
from the h itch .
Driver messages
Driving with a trailer requires extra caution.
Weight d istribution
Towing a loaded trailer w ith an empty car resu lts
in a hig hly unstable dist ribution of weight . If this
cannot be avo ided, drive at very low speeds on ly
to avoid the risk of losing s teering con trol.
A "balanced " rig is eas ier to operate and control.
This means that the tow vehicle should be loaded
to the extent possible and permissible , while
keep ing the tra ile r as lig ht as possib le under t he
circumstances . Whenever possible, t ransfer
some cargo to the l uggage compartment of the
tow vehicle whi le observ ing tongue load req uire­
ments and ve hicle loading conside rat ions.
Speed
The h igher the speed, the more d ifficult i t be­
comes for the drive r to contro l the rig. Do not
d rive at the maximum permissible speed. Reduce
your speed even more if load, weath er or w ind
conditions are unfavorable
-part icularly when
going downhill.
100
Reduce vehicle speed immediately if the trailer
shows the slightest sign of swaying.
Do not try
to stop the swa ying by a ccelerating.
Observe speed limits. In some a reas, speeds fo r
vehicles towing tra ilers are lower than for regular
vehicles .
Always apply bra kes early. Whe n driving down­
hill, shift in to a lower gea r to use the eng ine
b raking effect to slow the vehicle . Use of the
bra kes alone can cause them to overheat and fai l.
Coolant temperature
The coo lant tempe rat ure gauge 9 page 11 must
be obse rved caref ully. The coolant temperature
can increase i f you drive o n long inclines in a low
gear at high engine speeds . Reduce your speed
immediately if the LEDs in th e top part of the dis­
play turn on.
For more info rmation abou t indicator lig hts, re­
fer
to . ~page 30 .
A WARNING
Anyone not prope rly 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 wear ing the restraints provided
by Aud i.
Trailer towing
information
' Important to know
-
Your vehicle handles differently when towing a
trailer because of the addit ional weight and dif­
ferent weight distribution . Safety, performance
and economy will greatly depend on how ca refu l­
l y you load your tra ile r and ope rate yo ur rig.
Before you actually tow your trailer, pract ice
turning, stopping and backing up in an area away
from traffic . Keep pract icing u ntil you have be­
come complete ly familiar w ith the way yo ur vehi­
cl e- tra ile r combination behaves and respo nds.

Driving sa fe ty
Loose items in the luggage compartment can
shift s udden ly, changing vehicle handling charac­
ter istics. Loose items can also increase the risk of
serious personal in jury in a sudden vehicle
ma­
neuver or in a coll is ion.
.,. Distribute the load evenly in the luggage com­
partment .
.,. Always place and properly secure heavy items in
the luggage compartment as low and as far for­
ward as possible
c> fig . 226 .
.,. Secure luggage us ing the tie-downs provided
¢ page 73 .
.,. Make su re that the rea r seatbac k is securely
latched in place.
A WARNING
Improperly stored luggage or othe r items can
fly through the vehicle causing serious per­
sonal injury in the event of hard braking or an
accident. To help reduce the risk of serious
personal injury:
- Always put objects, for example, luggage or
other heavy items in the luggage compart­
ment.
- Always sec ure objects in the luggage com­
partment using the tie-down eyelets and
s u itable straps.
A WARNING
Heavy loads will influence the way your vehi­
cle handles. To he lp reduce the r isk of a loss
of contro l leading to serious pe rsonal i njury:
- Always keep in mind when transporting heavy objects, that a change i n the center of
grav ity can also cause changes in vehicle
hand ling:
- Always distr ibute the load as even ly as
possible.
- Place heavy objects as far forward in the
luggage compartment as poss ible.
- Never exceed the Gross Axle Weight Rating
o r the Gross Vehicle Weight Rating specified
on the safety compliance sticker on the driv­
er's side B-pillar respective ly on the front
end of the driver's door. Exceeding permissi­
ble weight standards can cause the veh icle
to slide and handle differently .
