:E: ' _& WARNING
-If you do not begin driving immediately or
the engine stalls after releasing the brake pedal, your vehicle may begin to roll back­
ward . Press the brake pedal or set the park­
ing brake immed iately.
- The intelligent technology of hill hold assist
cannot overcome the lim itations imposed by
natural physical laws. The increased comfort
offered by hill hold ass ist should not cause
you to take safety risks .
- Hi ll hold assist cannot hold the veh icle in
place on all hills (for example, if the ground
is slippery or icy).
- To reduce the risk of an accident, always
make sure the vehicle is situated safely
wh ile stat ionary.
Off road driving
General information
The electronic stabilization contro l (ESC) func­
tions were enhanced for driving offroad. Offroad
mode can be activated when driving in situat ions
where slippage or a differential lock function is
necessary
Q page 149. The hill descent ass ist is
a lso available, which automatically brakes the ve­
hicle and maintains a constant speed as a result
~page 150. In addition, your Audi prov ides con­
tinuous all wheel drive.
H owever , your Aud i is not a purely offroad vehi­
cle . Your vehicle was not designed to d rive unde r
extreme ope rating conditions such as driving in
an expedition style.
Only drive in terrain that is suitable for the vehi­
cle and your driving ability . Never take any un­
necessary risks!
Before driving offroad
- Check the eng ine oil level, the tire pressure, the
coolant level and the fluid level in the washer
fluid reservoir .
- Store pieces of luggage and other objects in the
luggage compartment and secure them from
s li ding out of place.
Driving
After driving offroad
-After driving offroad, remove branches and
other debris from the radiator grille, under­
body, and wheels . Look especially for foreign
objects (such as stones) that may be stuck in
the tire tread.
- Clean the vehicle body and underbody and in­
spect the vehicle for possible damage.
- Clean the windows, headlights, tail lights and
the license plate if they are dirty.
- Per form a brake test (especially after driving
through water).
_& WARNING
- Be especially cautious and aware when driv­
ing under difficu lt cond it ions and when off­
road. Veh icle damage and injuries may occur
when dr iv ing at excessively high speeds or
with incorrect driving maneuvers.
- Always adjust your speed and driving style
to the roads, terrain, traffic and weather
conditions . Drive especially slowly if there is
low visibility when offroad.
- Please note that the wheels can sp in more
and the vehicle can swerve when in offroad
mode, espec ially when the road is slippery
or has loose surface material.
- Driving stability is reduced when in offroad
mode.
@ For the sake of the environment
Avoid harming the environment and show
consideration for nature .
(D Tips
Only drive where it is permitted and always
stay on the prov ided roads and paths .

Trailer towing
- Changes in temperature or load can affect
the height of the vehicle .
- Always se lect
Auto or Comfort mode. Ot h­
erwise, the tongue load specified for your
vehicle will no longer be applicable.
Messages
Driving with a trailer requires extra caution .
Weight distribution
Towing a loaded trailer with an empty car res ults
i n a hig hly unstable dist ribution of weight. If this
cannot be avo ided, drive at ve ry low speeds o nly
to avoid the risk of lo sing s teeri ng con trol.
A "balanced" rig is eas ie r to operate and cont rol.
T his means that the tow veh icle should be loaded
to the exte nt poss ible a nd permiss ible , while
keep ing the tra ile r as lig ht as possib le unde r th e
circumstances . Whenever possible, transfer
some cargo to the l uggage compa rtment of the
tow vehicle whi le observ ing tongue load req uire­
ments and ve hicle loading considerat ions.
Speed
T he higher the spee d, the more d ifficult i t be­
comes for the drive r to co ntro l the rig. Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or w ind
conditions a re unfavorable -part icularly when
going downhill.
Re du ce veh icle spee d
immediately if the trai le r
shows the s lightest sign o f swaying.
Do not try
to stop the sway ing by accele rating .
Observe speed lim its. In some areas, speeds for
ve hicles towing trai lers are lower than for reg ular
veh icles.
A lways app ly b rakes early. When dr iv ing down ­
hi ll, shift into a lower gear to use the engine
braking effect to slow the veh icle. Use of the
brakes a lone can cause them to ove rheat and fail.
Air suspension*
If you are connecting a trailer to a fa cto ry -ins tal­
led trai ler hitch, trai ler mode a utomat ic all y
switches on in the ai r suspensio n. This will limit
the reg ulation by the a ir s usp ension whi le dr iv -

ing . If you want to swi tch off tra iler mode wh ile
driving, for example when using a bicycle rack system, se lect in the Infota inment system :
IM ENUI button> Vehicle > left control button>
Vehicle settings > Air suspension: trailer .
If the vehicle has a retrofitte d tra iler hitc h, the
trailer mo de might not switch on automatically .
In this case, switch the tra iler mode on before
hitc hing the tra iler and switch it off after un­
hitc hing the tra ile r.
Coolant tempe rature
The coo lant tempe rat ure gauge c:::> page 11 m ust
be obse rved caref ully. The coolant temperature
can increase if you drive o n long inclines in a low
gear at high eng ine speeds. Reduce your speed
i mmediately if the LEDs in the top part of the d is ­
play turn on .

Cooling system
Coolant
The engine cooling system is filled with a mixture
of pur ified water and coolant addit ive at the fa c­
tory. This coolant must not be not changed.
The coolant leve l is monitored through the. in­
d icator light~
page 26. Howeve r, we do recom­
mend occasionally check ing the coo lant level
manually.
I f you must add coolant, use a m ixt ure of water
a nd coolant addit ive. M ixing the coolant additive
with d istilled water is recommended .
Coolant additive
The coolant addit ive is made of anti-freez ing and
corros ion protection agents. Only use the fo llow­
ing coolant add it ives. These additives may be
mixed w ith each other.

The amount of coo lant additive that needs to be
mixed with water depends on the climate where
the vehicle will be operated. If the coolant addi­
tive percentage is too low, the coolant can freeze
and damage the eng ine.

- Befo re the start of winter, have an author­
i zed Audi dealer or authorized A udi Se rvice
Fac ility check if the coolant additive in your
328
vehicle matches the per cen tage appropriate
for the climate . This is especially important
when driving in colder climates.
- If the appro priate coo la nt additive is not
availab le in an eme rgency, do not add any
ot her additive. You could damage the en­
gine. If this happens, only use water and re­
store the correct mixture ratio with the
specified coolant add itive as soo n as poss i­
ble.
- Only ref ill w ith new coolant.
- Radiator sealant must not be mixed with
the coolant.

.. Make sure that the fluid level remains stable .
Add more coolant if necessary .
.,. Turn the cap to the right to secure it until yo u
feel resistance a second time.
Coolant loss usually indicates there is a leak . Im­
mediately drive your vehicle to an authorized
Audi dealer or authorized Aud i Service Facility
and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheating
and being pushed out of the cooling system.
A WARNING
-The cooling system is under pressure. Do
not open the coolant expansion tank cap
when the eng ine is hot. This increases the
risk of burns .
- The coolant additive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ign ition is switched off, which
increases the risk of injury.
CD Note
Do not add coolant if the expansion tank is
empty. There may be air in the cooling sys­
tem, which increases the risk of engine dam­
age . If this is the case, do not continue driv­
ing . See an authorized Audi dealer or author­
ized Audi Service Facility for assistance.
