.,. Pull on the switch (V) ¢ fig. 80 to apply the
parking brake . The indicator light in the
switch illuminates.
.,. Step on the brake pedal or the accelerator
pedal and press the switch
© at the same
time to release the parking brake. The indi­
cator light in the switch goes out.
Your vehicle is equipped with an electrome ­
chanical parking brake . The parking brake is
designed to prevent the vehicle from rolling
unintentionally and replaces the hand brake .
In addition to the normal functions of a tradi ­
tional hand brake, the electromechanical
parking brake provides various convenience
and safety functions .
When starting from rest
-The integral starting assist helps you when
driving by automatically releasing the park ­
ing brake
~ page 79, Starting from rest .
-When starting on inclines, the starting as ­
sist prevents the vehicle from unintentional­
ly rolling back. The braking force of the
park ing brake is not released until sufficient
driving force has been built up at the
wheels. .,,_

Emergency brake fun ction
An emergency brake ensures that the vehicle
can be slowed down even if the
normal b rakes
fail

@ Tips
-You can apply the pa rking brake at any
time -even w ith the ignition swi tched
off. The ignition must be on in order to
release the parking brake.
- Occasiona l noises when the parking
brake is applied and re leased are norma l
and are not a ca use for concern .
- When the vehicle is parked, the parking brake goes thro ugh a se lf-test cycle at
r egular intervals . Any assoc iated noises
are norma l.

A WARNING
-When you leave your vehicle -even if on ­
ly briefly -always take the ign it ion key
with you . This applies particularly when
children remain in the vehicle . Othe rwise
the children could start the engine, re­ lease the parking brake or operate elec­
trica l equipment (e.g. power wi ndows).
There is the r is k of an accident.
- When the veh icle is locked, no one -par­
ticularly not childre n should rema in in

80 On the road
Starting and automatically releasing the
par king brake
.. When you sta rt 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 stopping
in city traffic, the parking brake can be ap­
plied. The veh icle does not have to be held
with the footbrake. The parking 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 veh icle sta rts to move .
Starting on slopes
When starting on inclines, the starting assist
prevents the vehicle from unintentionally roll­
ing back . The braking force of the parking
brake is not released until sufficient dr iving
fo rce has been bu ilt 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 buck le.
Starting off with a trailer
To prevent rolling back unintentionally on an
incline, do the following:
.. Keep the switch l pulled and depress the
accelerator. The park ing brake stays applied
and prevents the vehicle from rolling back­
ward.
.. You can release the switch
C®l once you are
sure that you a re developing enough for­
ward momentum at the wheels as you de­
press the accelerator .
Depending on the weight of the rig (vehicle
and trai ler) and the seve rity of the incline, you
may roll backwards as you start. You can pre­
vent rolling backwards by holding the parking brake switch(®) pulled out and accelerating -
just as you would when starting on a hill with a conventional hand brake .
Emergency braking
In the event that the conventional brake sys­
tem fails or locks .
.. In an emergency, pull the switch C®l and
con tinue to pull it to slow your vehicle down
w ith the park ing brake.
.. As soon as you release the switch (®) or ac-
celerate, the brak ing process stops.
If you pull the switch C®l and hold it above a
speed of about 5 mph (8 km/h), the emergen­
cy brak ing funct ion is initiated . T he vehicle is
braked at all fou r whee ls by activating the hy­
draulic brake system. The brake performance
is similar to making an emergency stop~&. .
In order not to act ivate the emergency brak­
ing by mis take, an audib le warning tone (buz­
zer) sounds whe n the switch(®) is pulled . As
soon as the sw itch C®l is released , or the accel­
erator pedal is depressed, emergency braking
stops.
_& WARNING
-Emergency braking should only be used in
an emergency, when the normal foot brake
has failed or the brake pedal is obstructed.
Using the parking brake to perform emer­
gency braking will slow your veh icle down
as if you had made a full brake application .
The laws of physics cannot be suspended
even with ESC and its associated compo­
nents (ABS, ASR, EDL) . In corners and
when road or weather conditions are bad,
a full brake application can cause the vehi­
cle to skid or the rear end to break away -
risking an accident.
Start-Stop-System
Description
Applies to vehicles: with Start -Stop -System
T he Start -Stop-System can help increase fuel
economy and reduce CO 2 emissions.
In the Start-Stop-mode, the engine shuts off
automat ically when the veh icle is stopped,
such as at a traffic light. The ignition remains .,.

switched on during this stop phase. The en­
gine will be automatically restarted when
needed.
The last Start-Stop-System setting (on/off us­
ing the button

starts again when you select another selector
lever position and take your foot off the brake
pedal.
If you select the R position during a Stop
phase, the engine will start again .
Shift from D to P quickly to prevent the engine
from starting unintentionally when shifting
through R.
You can determine for yourself if the engine
will stop or not by reducing or increasing the
amount of force you use to press the brake
pedal. For example, if you only lightly press
on the brake pedal in stop-and and-go traffic
or when turn ing, the engine will not switch off
whe n the vehicle is stationary. As soon as you
press the brake down ha rder, the engine will
switch off.

Speed warning system
Introduction
The speed warning system helps you to stay
under a specified maximum speed.
The speed warning system warns you if you
a re exceeding the max imum speed that you
have set. You w ill hear a warn ing tone when
your speed exceeds the stored va lue by ap­
p rox ima tely 3 mph (3 km/h) . An indicato r
l ight . (USA models)/ . (Canada mode ls) in
t he ins trumen t cluster display also turns on at
the same time. The indicator light
a;m
turns off when the speed decreases below the
stored maximum speed.
Setting a threshold is recommended if you
wou ld like to be reminded when you reach a
certain maximum speed . Situations where you
may want to do so include driving in a country
with a general speed limit or if there is a
specif ied max imum speed for winter tires.
(D Tips
Even tho ugh your vehicle is equipped with
a speed warning system, you should st ill
On the road 83
watch the speedometer to make sure you
are not driving faster than the speed limit.
Setting the threshold
You can set, chang e and delete the threshold
in the MMI.
.,. Select: I CAR I function button > (Car)* sys­
tems
control button > Driver assist > Speed
warning.
You can set any threshold between 20 mph
(30 km/h) and lS0 mph (240 km/h). Sett ings
can eac h be adjusted in increments of 6 mph
(10 km/h).
Cruise control

A WARNING
- Always pay attention to traffic even when
the cruise control is switched on. You are
always responsible for your speed and
the distance between your vehicle and
other vehicles .
- For safety reasons, the cruise control
should not be used in the city, in stop­
and-go traff ic, on twist ing roads and
when road conditions are poor (such as ice , fog, gravel, heavy ra in and hydro­
planing) -risk of accident.
- Turn
off the cruise control temporar ily
when entering turn lanes, highway exit lanes or in construc tion zones.
- Please note that inadvertently "rest ing"
yo ur foot on the accelerator peda l causes
the cruise control not to brake . T his is
because the cr uise control is overridden
by the d river's acce leration .
- If a brake system malfunction such as
overheating occurs when the cruise con­
tro l system is switched on, the braking
function in the system may be switched
off. The other cruise control functions re­
ma in active as long as the indicator light
