@ Tips
-You can apply the pa rking brake at any
time - even with the ignition switched
off. The ignit ion must be t urned on in or ­
der to release the parking brake.
- Occas iona l noises when the parking
brake is applied and re leased are norma l
and are not a cause for concern.
- When the vehicle is parked, the parking
brake goes through a se lf-test cycle at
regular intervals. Any assoc iated noises
are normal.

.&_ WARNING
-Whe n you leave your veh icle -even if on­
ly briefly - a lways remove the ign ition
key . This applies part icu larly when chil ­
dren remain in t he vehicle . Otherwise the children could start the eng
ine, release
the park ing brake or operate electrical
equ ipment (e.g. power windows). There
is the risk of an acc ident.
- When the veh icle is locked, no one - par­
ticularly not children should rema in in
the vehicle . Locked doors make it more
difficul t for emergency wo rke rs to get in­
to the vehicle - putting lives at r isk.
Starting from rest
The starting assist function ensures that the
parking brake is released automatically upon starting.
Stopping and applying par king brake
> Pull the switch @¢ page 79, fig. 92 to ap-
ply the parking brake.
Sta rting and automatically relea sing the

> When you sta rt to dr ive as usual, the park ­
ing brake is automat ically released and your
veh icle beg ins to move.
When stopping at a traffic signal or stopping in city traffic on vehicles with an a utomatic
transmission, the parking brake can be ap­
plied . The vehicle does not have to be held
with the footbrake . T he parking brake elimi­
nates the tende ncy to creep w ith a dr ive range
engaged. As soo n as yo u drive
off as usu a l,
the parking bra ke is re leased automatically
and the vehicle starts to move .
Starting on slopes
When starting on inclines, the sta rting assist
preve nts t he veh icle from u nintent ionally roll­
i ng back. The br aking for ce of the park ing
brake is no t re leased unt il suff icien t driving
f orce has been built up at the w heels.
(D Tips
Fo r saf ety reaso ns, the pa rking br ake is re­
l eased a utom atically on ly when t he d riv­
er's safety belt is engaged in the buckle.

Emergency braking
In the event that the conventional brake sys­tem fails or locks .
11-In an emergency, pull the switch @
r:::;, page 79, fig. 92 and cont inue to p ull it to
slow your veh icle down with the park ing
brake.
11-As soon as you release the sw itch @ or ac-
c e le rate, the braking p rocess stops.
If you pull t he sw itch @and hold it above a
speed of about 5 mph (8 km/h), the emergen­
cy braking fu nction is in itiated. The vehicle is
b raked at a ll four wheels by activating the hy ­
d ra ulic brake system. The b rake performance
is simi lar to making an emergency stop
r:::;, &. .
In o rder not to activate the emergency brak­
i ng by m istake, an a udible warning tone (b uz­
zer) sounds when the switc h @ is pu lled . As
soon as the switch @is released, or the accel­
erator pedal is depressed, emergency brak ing
stops.
A WARNING
Emergency braking should only be used i n
an emergency, when the normal foot brake
has failed or the brake pedal is obstructed.
Using the parking bra ke to perform emer­
gency braking will slow you r vehicle down
as if you had made a fu ll brake applicat ion.
The laws o f physics cannot be s uspended
even w ith ESC and its associated compo­
nents (ABS, ASR, EDS). In corne rs and
when road or weather conditions a re bad,
a full brake application can cause the vehi­
cle to skid or the rear end to break away -
r isking an accident.
Speed warning system
Overview
The speed warning system helps you to keep
your driving speed below a set speed limit.
The speed warning system warns if the driver
exceeds a prev iously stored maximum speed .
A wa rning tone wi ll sound as soon as the vehi-
On th e ro ad 81
cle speed exceeds the set speed by about
3 mph (3 km/h). At the same time, a warning
symbol appears in the display. The symbo l's
appearance might be different in some mod­
els.
The speed warning system has two warning
th resholds that funct ion independent ly of
each other and that have somewhat different purposes:
Speed warning 1
You can use speed warning 1 to set the maxi­
mum speed while you are driving. This setting
will remain in effect unti l yo u turn off the ign i­
tion, assuming that you have not changed or reset the setting.
The . (USA mode ls)
I. (Canada mode ls)
speed warning symbo l in the warning 1 dis­
play appears when you exceed the maximum
speed . It goes out when the speed falls be low
the sto red maximum speed .
The speed warn ing symbol will also go out if
the speed
exceeds the stored maximum speed
by more than about 25 mph (40 km/h) for at
least 10 seconds . The stored max imum speed
is deleted.
Speed w arning 2
Storing warning 2 is recommended if yo u al­
ways
want to be reminded of a certain speed,
for example whe n you are trave ling in a coun­
try that has a general maximum speed limit,
o r i f you do not want to exceed a specified
speed for w inte r tir es.
The . (USA models) /. (Canada models)
speed warning 2 symbol appears in the dis ­
play when yo u exceed the stored speed limit.
Unlik e warning 1, it will not go out unt il the
vehicle speed dro ps below the s to red speed
li mi t.

watch the speedometer to make sure you
are not driving faster than the speed limit.
Speed warning 1: setting a speed limit
Warning threshold 1 is set by the ISE T! but­
ton.

onds.
The . (USA models)/ . (Canada models)
speed warning symbol will appear briefly in
the display when you release the !SET! button
to indicate that the maximum speed has been
stored successfully .
The maximum speed remains stored until it is
changed by pressing the !SE T! button again
briefly or until it is de leted by a lengthy push
on the button .

A WARNING ,~
- Always pay attention to the traffic
around you whe n the cruise contr ol is in
o peration . You are always responsi ble for
your s peed and the distance between
yo ur vehicle and other vehicles.
- For reasons of safety, cruise contro l
should not be used in the city, in stop­
and-go traff ic, on twisting roads and
when road conditions are poor (su ch as
ice, fog, grave l, heavy rain and hydro ­
planing) -risk of accident.
- T urn off the cru ise control tempo rar ily
when entering turn lanes, highway exit
lanes or in construction zones.
- Please note that inadvertent ly "rest ing"
yo ur foot on the accelerator peda l causes
the cruise control not to brake. Th is is
because the cr uise control is overridden
by the driver's acce lerat ion.
- If a brake system malfunction such as
overheat ing occurs when the cruise con­
tro l system is sw itched on, the braking
function in the system may be switched
off. The other cruise control f unctions re­
main active as long as the i nd icator light

In the norm al mode D, the transmission auto­
matically selects the suitable gear ratio. It de­
pends on engine load, vehicle speed and driv­
ing style.
Select the
sport mode S for sporty driving.
The vehicle makes full use of the eng ine 's
power. Shifting may become noticeable when
accelerating.
When the vehicle is stationary or at speeds
below 1 mph (2 km/h), you must always apply
the foot brake before and while moving the lever to D/S out of N.

~

88 Transmission
-Unintended vehicle movement can cause
serious injury .
- Never leave your vehicle with the engine
running while in gear. If you must leave
your vehicle when the engine is running,
activate the parking brake and move the
selector lever to P .
- Power is still transmitted to the wheels
when the engine is running at idle. To
prevent the vehicle from "creeping", you
must keep your foot on the brake when
the engine is running and the selector
lever is in D/S or R or "tiptronic" mode is
selected.
- Do not press the accelerator pedal when
changing the selector lever position
while the vehicle is stationary and the
engine is running.
- Never shift into
R or P while driving.
- Before driving down a steep slope, re-
duce your speed and shift into a lower
gear with "tiptronic".
- Do not ride the brakes or press the brake
pedal too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases
braking distance or causes complete fail­
ure of the brake system.
- To prevent the vehicle from rolling back
when stopping on inclines, always hold it
in place with the brake pedal or parking
brake .
- Never hold the vehicle on an incline with
a slipping clutch . The clutch opens auto­
matically when it becomes too hot from
the overload . An indicator lamp
[O] illu­
minates and a driver message appears
Q page 90 when the clutch is overload­
ed.
- If the engine must remain running, never
have any driving position engaged when
checking under the hood. Make sure the
selector lever has securely engaged and
is locked in P with the parking brake set
Q page 200, Engine compartment . Oth­
erwise, any increase in engine speed may set the vehicle in motion, even with the
parking brake applied.
@ Note
- When stopping on an incline, do not try
to hold the vehicle in place by pressing
the accelerator pedal while a driving gear is selected. This can cause the transmis­
sion to overheat and can damage it. Acti­
vate the parking brake or press the brake
pedal to prevent the vehicle from rolling .
- Allowing the vehicle to roll when the en­
gine is stopped and the selector lever is
in N will damage the transmission be­
cause it is not lubricated under those cir­
cumstances.
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the driv­
er's safety belt is engaged in the buckle.
Hill descent control
The hill descent control system assists the
driver when driving down declines.
Hill descent control is activated when these ­
lector lever is in D/S and you press the brake
pedal. The transmission automatically selects
a gear that is suitable for the incline. Hill de ­
scent control tries to maintain the speed ach­
ieved at the time of braking, within physical
and technical limitations. It may st ill be nec­
essary to adjust the speed with the brakes.
Hill descent control switches off once the de­
cline levels out or you press the accelerator
pedal.
On vehicles with the cruise control system*
Q page 82 , hill descent control is also activat­
ed when the speed is set.
A WARNING -
Hill descent control cannot overcome
physical limitations, so it may not be able
to maintain a constant speed under all

conditions. Always be ready to apply the
brakes.
Manual shift program
Using the manual shift program you can
manually select gears.

When accelerating, the transmission does
not
automatically shift to the next gear shortly
before the maximum permitted engine RPM is
reached.
If you have selected a lower gear than the cur­
rent one, the automatic transmission will shift
down only when the engine will not be over­
revved.
With kick-down, the transmission shifts into a lower gear depend ing on speed and engine
RPM .
(D Tips
Tiptronic is inoperative when the transmis­
sion is in the fail-safe mode .
, Kick-down
Kick-down enables maximum acceleration.
When you depress the accelerator pedal be­
yond the resistance point, the automatic
transmission downshifts into a lower gear, de­
pending on vehicle speed and engine speed .
The upshift into the next higher gear takes
place once the maximum specified engine
speed is reached .
.&_ WARNING
Please note that the whee ls can spin if
kick-down is used on a smooth s lippery
road -there is a risk of skidding.
