system.
A WARNING , ~
To reduce the risk of poisoning, never allow
the engine to run in confined spaces.
-
@ Note
Avoid high engine speed, full throttle, and
heavy engine load if the engine has not
reached operating temperature yet. You could
damage the engine.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately. This re­
duces unnecessary emissions.
(D Tips
-Some noise after starting the engine is nor­
mal and is no cause for concern.
- If you leave the vehicle with the ignition
switched on, the ignition will switch off af­
ter a certain amount of time. Make sure that
electrical equipment such as the exterior
lights are switched off.
Starting the engine
.,. Bring the vehicle to a full stop.
.,. Press the
I STAR T ENGINE STOPI button
r::!:> page 82, fig . 86 .
Emergency off function*
If it is absolutely necessary, the engine can also
be turned off while driving at speeds starting at
4 mph (7 km/h) . To switch the engine off, press
the
! START ENGINE STOPI button twice in a row
briefly or press and hold for longer than two sec­
onds.
A WARNING
- Never turn off the engine before the vehicle
has come to a complete stop. The full func­
tion of the brake booster and the power
steering is not guaranteed. You must use
Driving
more force to turn or brake. Because you
cannot steer and brake as you usually
would, this could lead to accidents and seri­ ous injuries .
- Always take the key with you whenever you
leave your vehicle. Otherwise, the engine
could be started or electrical equipment
such as the power windows could be operat­
ed. This can lead to serious injury.
- For safety reasons, always park the vehicle with the selector lever in the P position .
Otherwise, there is the risk that the vehicle
could roll unintentionally .
(D Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after the engine is
switched off and there is a risk of damaging
the engine. For this reason, let the engine run
for at idle for approximately two minutes be­
fore shutting it off.
(D Tips
For up to 10 minutes after stopping the en­
gine, the radiator fan may turn on again auto­
matically or it may continue to run (even if
the ignition is switched off) for the following reasons :
- The coolant temperature is increasing due
to trapped heat .
- If the engine is warm and the engine com­
partment also heats up from strong sun­
light.
- Applies to: vehicles with diesel particulate
filter: The emissions control system is heat­
ed through the regeneration process, even if
the engine has not reached its operating
temperature yet .

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 .

parking aids will help you when parking and ma­
neuvering.
The
rear parking system is an audible parking aid
that warns you of obstacles
behind the vehicle
¢ page 139.
The
parking system plus assists you when park ­
ing by audibly and visually indicating objects de­
tected
in front of and behind the veh icle
¢ page 139.
The
rearview camera shows the area behind the
vehicle in the Infotainment system display . The
lines in the rearview camera image help you to
park or maneuver
¢ page 140. The parking sys­
tem plus functions are also available
¢ page 139.
The
peripheral cameras give various views to
help you when parking or maneuvering
¢ page 143. The parking system plus functions
are also available
¢page 139.
A WARNING i-==
- Always look for traffic and check the area
around your vehicle by looking at it directly
as well. The parking system cannot replace
the driver's attention. The driver is always
responsible when entering or leaving a park­
ing space and during similar maneuvers.
-
- Please note that some surfaces , such as
clothing, are not detected by the system .
- Sensors and cameras have blind spots in
which people and objects cannot be detect­
ed . Be especially cautious of small children
and animals .
- Always keep your eyes on the vehicle's sur ­
roundings, using the rearview mirror as
well.
- The sensors can be displaced by impacts or
damage to the radiator grille, bumper,
wheel housing and the underbody. The park­ ing system may be impa ired as a result.

Have an authorized Audi dealer or author­
ized Audi Service Facility check their func­
tion.
(D Note
- Some objects are not detected or displayed
by the system under certain circumstances:
- objects such as barrier chains, trailer draw
bars, vertical poles or fences
- objects above the sensors such as wall ex ­
tensions
- objects with certain surfaces or structures
such as chain link fences or powder snow
- If you continue driving closer to a low ob­
ject, it may disappear from the sensor
range. Note that you will no longer be
warned about this obstacle.
- Keep enough distance from the curb to re ­
duce the risk of damage to the rims.
{i) Tips
- The system may provide a warning even
though there are no obstacles in the cover ­
age area in some situations, such as:
- certain road surfaces or when there is tall
grass
- external ultrasonic sources such as from
cleaning vehicles
- in heavy rain, snow, or thick vehicle ex­
haust
- We recommend that you practice parking in
a traffic-free location or parking lot to be­
come familiar with the system . When doing
this, there should be good light and weath­
er conditions.
- You can change the volume of the signals
and the display ¢
page 146.
- Please refer to the instructions for towing a
trailer located in
¢page 147.
- What appears in the infotainment display is
somewhat time-delayed.
- Th e sensors must be kept clean and free of
snow and ice for the parking aid to operate .

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.
Coolant additive Specification

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.
Coolant Freeze protec-
additive tion
Warm min .40% m in. -13 °F
reg ions max. 45% (-25 °()
Cold min. 50% max. -40 °F

- 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.

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.
