(D Tips
- You can apply the parking brake at any
time - even w ith the ignition switched
off . Th e ignit ion must be t urned on in o r­
der to release the par king brake. - Occasional noises when the parking
bra ke is applied and released are normal
and are not a cause for concern.
- When the vehicle is parked , the parking
brake goes through a self-test cycle at
regu lar interva ls. Any associated noises
are normal.

pa rking b rake
~ When you start to drive as usua l, the park­
ing brake is automatically re leased and your
vehicle begins to move.
When stopping at a traffic signa l or stopp ing
in city traffic on vehicles with an automatic
transmission, the parking brake can be ap­ plied. The vehicle does not have to be held
w ith the footbrake . The park ing brake elimi­
nates the tendency to creep with a drive range
engaged. As soon as you dr ive off as usual,
the park ing brake is released automatically
and the vehicle sta rts to move .
Starting on slop es
When starting on inclines, the start ing ass ist
prevents the vehicle from unintentionally roll­
ing back. The braking force of the parking
brake is not released until sufficient dr iving
force has been b uilt up at the whee ls.
(D Tips
For safety reasons, the park ing brake is re­
leased automatically only when the dr iv­
er 's safety belt is engaged in the bu ckle.
Starting off with a trailer
To prevent rolling back unintentionally on an
incline, do the following:
~ Keep the switch@¢ page 85, fig . 98
pulled and depress the accelerator . The
park ing b rake stays app lied and p revents
the vehi cle from rolling backward.
~ You can release the switch @once you are
s u re that yo u are developing enough driving
force at the wheels by depressing the accel­ erator.
D epending on the weight of the rig (vehicle
and trai ler) and the severity of the incline, you
may roll backwards as you start. Yo u can pre­
vent roll ing backwards by holding the parking
brake switch @pulled out and accelerating -
just as you would when starting on a hill wit h
a conventional hand brake .
On the ro ad 87
Emergency braking
In the event that the conventional brake sys­
tem fails or locks .
~ In an emergency, pull the sw itch @
¢
page 85, fig. 98 and continue to pull it to
slow your vehicle down with the parking
brake .
~ As soon as you release the switch @ or ac-
celerate, the b ra ki ng process s tops.
If you pull the switch @and hold it above a
speed of about 5 mph (8 km/h), the eme rgen­
cy bra king funct ion is initia ted . T he ve hicle is
braked at all four whee ls by activating the hy­
draulic brake system. The brake performa nce
is similar to making an emergency stop¢&..
In order not to act ivate the eme rgency brak­
ing by mis take, an audib le warning tone (buz ­
zer) so unds when the switch @is pulled. As
soon as the switch @ is re leased, or the acce l­
erato r peda l is depressed, emergency braking
stops.
A WARNING
...--
Emergency braking should only be used in
an emergency, when the normal foot brake has fa iled or the brake pedal is obstructed .
Using the par king b rake to pe rform eme r­
gency brak ing will slow your vehicle down
as if you had made a full bra ke application.
The laws of physics cannot be suspended
even with ESC and its associated compo ­
nents (ABS, ASR, EDS) . In corners and
when road or weather conditions are bad,
a full brake application can ca use the vehi­
cle to sk id or the rear end to break away -
risking an accident.

On th e road 89
The speed is kept constant by modifying en­
gine power or through an active brake inter­
vention.
_& WARNING
- Always pay attention to the traffic
around you when the cruise control is in
operation. You are always responsible for
your speed and the distance between
your veh icle and other vehicles.
- For reasons of safety, cru ise control
should not be used in the city, in stop­
a nd-go traffic, on twisting roads and
when road cond itions are poor (such as
ice, fog, gravel, heavy rain and hydro­
p lan ing) -risk of accident .
- Turn
off the cruise control temporar ily
when enter ing turn la nes, highway exit
lanes or in construction zones .
- Please no te that inadverten tly "resting"
your foot on the accelerator pedal causes
the cruise contro l not to brake. This is
because the cruise control is overridden
by the driver's acceleration.
- If a brake system malfunction suc h as
overheating occurs when the cruise con­
trol system is switched on, the braking
function in the system may be switched
off. The other cruise contro l functions re­
main active as long as the indicator l igh t
lijj(l)~i~ (US mode ls)/ Iii (Canad ian mod­
e ls) is on.
@ Tips
- Veh icles with ma nual transmiss ion: You
can attain the set speed only if the gear
that is currently engaged will a llow it, or
if it does not tax the engine a nd allows i t
t o r un smoothly. Therefore shift in to a
higher or lower gear in a time ly manner.
- The bra ke ligh ts ill umina te as soon as
the brakes app ly au tomatically.

tions by hand ¢
page 96.
On s lopes, activate the parking brake first and
then move the selector lever to the P position .
This prevents too much stress from being
placed on the locking mechanism .
Vehicles with multitronic transmission: Your
vehicle is equipped with
hill hold assist allow­
ing yo u to start while on an incline. The sys ­
tem is activated when the brake pedal is
pressed down and he ld
for a few seconds . The
brake pressure will hold for
a moment after
the brake pedal loosens to prevent the vehicle
from roll ing backwards w hile starting up .
A WARNING
-The vehicle can also roll when the engine
is stopped.
-Unintended vehicle movement can cause
serious injury.
- Never leave your vehicle with the engine
r un ning while in gear. If you must leave
your veh icle 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 runn ing 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 0/5 or R or "t iptronic" mode is
selected .
- Do not press the accelerator pedal when changing the selector lever position
while the veh icle is stationary and the
engine is running.
- Never shift 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 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
¢ page 9 7 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
¢ page 213, Engine compartment . Oth­
erwise, any increase in engine speed may
set the vehicle in motion, even with the
parking brake applied .
0 Note
-S tronic ®- and tiptronic transmission:
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.
- S tronic ®- and tiptronic transmission: Al­
lowing 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 .

Hill descent control
App lies to veh icles: w it h m ult itro nic/S tro nic/t iptro nic
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 still 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*
¢ page 89 , hill descent control is also activat­
ed when the speed is set.
.&_ 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.
