9=:7-: Engine oil pressure malfunction
The red engine oil pressure warning symbol
requires immediate service or repair. Driving
with a low-oil-pressure indication is likely to
inflict severe damage to the engin e.
If the . symbol appears in the display and
b links, the oil pressure is too low. An addition­
a l dr ive r message can also be d isp layed by
p ress ing t he
I CH ECKi b utton:
Switch off engine I Oil pressur e too low
Immediate a ction s
~ Pull off the road.
~ Stop the vehicle.
~ Turnoff the engine.
~ Check the engine oil le vel with the dipstick

260.
Dipstick reading s checks too low
~ Top off oi l to the proper level~ page 261.
~ Make sure that the oil pressure warning
symbol . appears no longer in the display
before you start driving aga in.
Dipstick reading checks OK
~ If the o il pressure warning symbol. starts
flashing again even though the engi ne oil

do not con­
tinue driving and do not let the engine run in idle.
Instead , contact your authorized
A udi dealer for assistance.
Dri ver information di spla y 33
(D Tips
- The engine oil pressure symbol. is
not an indicator for a low engine oil lev­
el. Do not rely on it . Instead, check the
o il level in your engine at regular inter ­
vals, preferably each time you refuel, and always before going on a long trip .
- The yellow oil level warn ing indication
l!I requires oil refill or workshop serv­
ice without delay . Do not wait until the
red oil pressure warning. start s to
flash before you respond to the low oil
level warning
m. By then, your engine
may already have suffered serious dam­
age.

After starting the engine, the headlights are

the rain sensor is not activated until vehicle
speed is above 4 mph (6 km/h).
To reduce the sensitivity of the rain sensor,
the switch@ must be moved down. To in­
crease the sensitivity of the rain sensor, the
switch must be moved up.
The higher the sensitivity setting, the sooner
the windshield wipers react to moisture on
the windshield . Increased sensitivity is sig­
naled by the windshield w ipers making a sin­
gle pass over the windshield.
The rain sensor wiper intervals depend on the
sensitivity setting as well as vehicle speed .
During brief stops, wiper motion will adjust in
relation to the amount of rain on the wind­
shield.
A WARNING
- Wiper blades are crucial for safe driving!
Only when they are in good condition are
they able to clear the windows properly
to provide uncompromised visibility .
Worn or damaged wiper blades are a
safety hazard
i:::> page 69, Replacing
windshield wiper blades!
- The rain sensor is only designed to assist
and support the driver.
It remains entire­
ly the driver's responsibility to monitor
outside weather conditions and to man­
ually activate the wipers as soon as rain
or drizzle reduces visibility through the
windshield .
(D Note
In freezing or near freezing conditions:
- Always check that the wiper blades are
not frozen to the glass before you turn
the wipers on. Loosen a wiper blade
which is frozen in place before operating
the wipers to prevent damage to the
wiper blade or the wiper motor .
- Do not use the wipers to clear a frosted
window . Using the wipers as a conven­
ient ice scraper will destroy the wiper
blades .
Clear vision 67
-Prior to using a car wash, the w indshield
wiper system must be switched off (lever
in position 0). This helps to prevent unin­
tentional switching on and damage to
the windshield wiper system.
(1} Tips
- The windshield wipers are switched off
when the ignition is turned off. Activate
the windshield wipers after the ignition
is switched back on by moving the wind­
shield wiper lever to any position .
- Worn or dirty windshield wiper blades
cause smearing which can affect the op ­
eration of the rain sensor . Check the con­
dition of your windshield w iper blades
regularly.
- The rain sensor is part of the interval
wiping system. Turning off the ignition
will also deactivate the rain sensor. To re­ activate the sensor, switch off the inter ­
val wiping function, then switch it back
on again.
- Make sure the washer fluid reservoir in
the engine compartment is topped off
before going on a long trip. Look up
i:::> page 2 70 for checking and filling the
washer container.

Hill descent c ontrol
The hill descent control is sw itched on in off­
road mode. When slowly descending steep
gradients on loose ground or when the axles
are articulated, hi ll descent control provides
assistance by automatically applying the
brakes to keep vehicle speed constant. The ve­
h icle is also rendered easier to steer by selec­
tive distribution of braking force . Hill descent
control intervenes when:
- the accelerator pedal is not pressed,
- the vehicle is travelling less than 12 mph
(20 km/h),
- a steep gradient is detected,
- wheel behavior indicates loose ground or
conditions with poor adhesion (e .g. also ax le
articulation) .
H ill descent control operates both dr iv ing for­
ward and in reverse. Active hill descent con ­
trol is deactivated by pressing the acce lerator
pedal until the conditions for act ivation al­
ready listed are met again.
A WARNING
You should only switch offroad mode on if
your dr iving abilities and road conditions
permit .
- The stabilization function is limited
when offroad mode is switched on. The
dr iv ing wheels could spin and the vehicle
cou ld swe rve, especia lly on slick or slip­
pery road surfaces.
- You should on ly sw itch offroad mode on
when d riving offroad .
(D Tips
Offroad mode cannot be switched on when
adaptive cru ise control* is sw itched on.
Brake system
Operating condit ions and d riving hab it s
The brakes on today's automob iles are st ill
subject to wear, depending largely on operat­
i ng conditions and dr iv ing habits ~& . On
vehicles that are e ither driven mostly in stop-
Int ellig ent technolog y 225
and-go city t raff ic or are driven hard, the
brake pads should be checked by your author­
ized Audi dea ler more often than specif ied in
the
Warranty & Mainten ance boo klet . Failure
to have your brake pads inspected can result
in reduced brake performance.
On steep slopes, you sho uld use the braking
effect of the engine . This way, you prevent un ­
necessary wear on the brake system. If you
must use your brakes, do not hold the brakes
down cont inuously . Pump the brakes at inter­
vals.
Noises may occur when braking depending on
the speed, braking force and outside condi ­
t ions such as temperature and humid ity .
Mo is ture or ro ad s alt
Under certa in conditions, for example, when
driv ing through water or very heavy ra in, or
even after washing your veh icle, the braking
effect can be reduced due to moisture (or in
freez ing cond itions ice) on the brake pads . A
few carefu l brake applications should dry off
the b rake pads or remove any ice coatings.
When you are drivi ng at higher speeds with
the windshield w ipers on, the brake pads wi ll
briefly touch the brake discs in regu la r i nter­
vals so as to improve react ion time when brak­
ing on wet sur faces. You, the drive r, wi ll no t
notice anything .
T he effect iveness of the brakes can be reduced
whe n the vehicle is d riven on a sa lt-cove red
road and the b ra kes are not used. He re too,
you should clean off accumulated sa lt coa ting
from brake discs and pads with a few caref ul
applications of the brake~& .
Corrosion
The re may be a tendency for di rt to b uild up
o n the br ake pads and corros io n to fo rm on
the d iscs i f the car is not driven regularly or
o nly for short trips with litt le use of the
brakes.
If t he brakes a re not used frequently, o r if cor­
ros ion has formed on the discs, it is adv isable
to clean off the pads and d iscs by braking .,.
