Starting on an incline
• Activate the parking brake .
• With the driving gear se lected, press the ac­
celerator pedal carefully. The parking brake
will release automat ically if your seat be lt is
fastened.
Dr ivin g on an incline: Under certain circum­
stances, such as driving in the mountains, it may be useful to sw itch temporarily to the
manual shift program in order to adjust the
gears to the driving conditions by hand

On slopes, activate the parking brake first and
then move the selector lever to the P posit ion.
This prevents the lock ing mechanism from be­
ing loaded too heav ily and w ill make it easier
to move the selector leve r out of P .
A WARNING
-Never leave your vehicle with the engine
running while in gear. If you must leave
your veh icle when the engine is running,
activate the pa rking brake and move the
selecto r lever to P .
- Powe r is still transmitted to the w heels
when the engine is runn ing at idle. To
p revent the vehicle from "c reeping", you
m ust keep your foot on the brake when
the engine is running and the selector
lever is in D/S or R or "t iptronic" mode is
selected.
- Do not press the accelerator pedal when changing the se lector lever position
while the veh icle is stationary and the
engine is running.
- Never sh ift into R or
P while driving .
- Before driving down a steep s lope, re-
duce your speed and shift into a lower
gear with "tiptronic".
- Do not ride the brakes o r press the bra ke
pedal too often or too long. Constant
brak ing ca uses the brakes to overheat
and substantially reduces braking per­
formance, increases braking d istance or
causes complete failure of the brake sys­
tem.
- To preve nt the vehicle from ro lling back
when stopp ing on inclines, always hold it
in place with the b rake pedal or parking
b rake.
- Never hold the vehicle on an incline with
a slipping clutc h. T he clutch opens auto­
mat ica lly when it becomes too hot from
the overload. An indica tor l amp
mJ ill u­
minates and a driver message appears

ed .
(D Note
-When s topping on an incl ine, do no t try
to hold t he vehicle in place by pressing
the acce lerator pedal while a driving gear
is se lected. This can cause the S t ron ic
transm ission to overheat and can dam­
age it. Activate t he parking brake or

Audi adaptive cru ise control and brakin g guar d 99
Vehicles with manual transmission
Applies to vehicles: with Audi adaptive cruise control
The adaptive c ruise control is avai lab le from
the 2nd gear through the 6th gea r in the cus­
tomary RPM.
When the adapt ive cruise control is turned on,
you must p ress the clutch to shift gears (as
usual) . When sh ifting normally or when press­
ing the cl utch, the adap tive c ruise control re­
mains turned on.
Afte r you have engaged the gear, you do
not
need to press the gas peda l. The adaptive
cru ise control accelerates a utomat ica lly if nec­
essary.
I f you press dow n on the clutch fo r too long or
shift/coup le improperly, the adaptive cruise
control may turn off automat ically.
{D) Tips
You cannot tu rn on the adapt ive cru ise
contro l during a sh ifting operation.
Audi adaptive cruise
control
Description
App lies to vehicles: with Audi adaptive cruise control
Fig . 99 Detectio n range
What c an adaptive cruise contr ol do ?
The adaptive cruise control works in conjunc ­
tion with a radar sensor installed in the front
of the vehicle¢
page 97 , fig. 96, which is sub­
ject to designated system limits ¢
page 99.
Stationary objects are d is regarded .
On open roads w ith no traff ic, adaptive cruise
control works like a regu lar cruise control sys- tern.
The stored speed is maintained . When
approaching a moving vehicle detected up
ahead, the adaptive cruise control system au ­
tomat ica lly s lows down to match that vehi­
cle's speed and then maintains the distance
that the driver previously stored . As soon as
the system does not detect a veh icle up
ahead, adaptive cru ise contro l accelerates
ba ck up to the stored speed.
Which fun ctions can be con trolled?
When you switch adapt ive cruise control on,
you can set the current speed as the "control
speed"
q page 100, Switching on and off.
When dr iving, you can stop cruise contro l
¢
page 101 or change the speed ¢ page 101
at any time.
You can also set the distance to the object
ahead and set the adapt ive cru ise contro l driv­
ing program
¢page 102.

-Switch Audi braking guard off when you
are loading the vehicle onto a vehicle car­
rier, train, ship or other type of transpor­
tation. This can prevent undesired warn­ ings from the braking guard system .

224 Checking and filling
scalding from hot coolant by following
these steps.
- Turn off the eng ine and a llow it to cool
down.
- Protect your face, hands and arms from escaping flu id and steam by cover ing
the cap with a large, thick rag.
- Turn the cap slowly and very carefully
i n a counter-clockwise direction while
apply ing l ight, downwa rd p ress ure on
the top of the cap .
- To avo id being burned, do not sp ill an­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts . Under certain
conditions, the ethylene glyco l in en­
gine coolant can catch f ire .
- Antifreeze is poisonous . Always store an­
tifreeze in its or iginal container and we ll
out of the reach of children .
- If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clear ly marked "poison".
@ Note
- Coolant po llutes the env ironment and
could cause an engine fire . Excess coo l­
ant will be forced out through the pres­
sure relief valve in the cap when the en­
gine becomes hot.
- If, in an emergency, on ly water can be
added, the correct ratio between water
and antifreeze
c::> page 222 must be re­
stored as soon as possible .
@ For the sake of the environment
Drained coolant should not be re used. Al­
ways dispose of used coolant while observ­
ing all environmental regulat ions.
Radiator fan
The radiator fan switches on automatically by
itself
The radiator fan is driven by the engine via the
V-be lt . The viscous clutch regulates the speed
of the fan according to the temperature of the
coolant. An a
uxiliary electric radiator fan* switches on
and off depending on coolant temperature
and other vehicle operat ing condit ions .
After yo u sw itch the engine off, the aux iliary
f an can continue running for up to 10 minutes
- eve n wit h the ignition off. It can even switc h
on again later by itself
c::> &. , if
- t he tempe rature of the engine coo lant rises
due to the heat build -up from the engine in
the engine compartment, or
- the engine compa rtment heats up because
the vehicle is parked in i ntense sunlight.
_& WARNING
- To reduce the risk of personal in jury nev­
er touch the radiator fan.
- The auxiliary electric fan is temperat ure
controlled and can sw itch on suddenly
even when the engine is not running.
- The a uxiliary radiator fan sw itches on a u­
tomatically when the engine coo lant
reaches a certai n temperature and will
continue to run until the coolant temper­
ature drops.
