Your veh icle is equipped w ith an electromechan i­
cal parking b rake. The par king b rake is designed
to p revent the veh icle from rolling unintentional­
ly and replaces the hand brake.
In addition to the norma l funct ions of a tradit ion­
a l hand bra ke, the e lectromechan ical pa rking
b rake provides var ious convenience and safety
f u nctions.
When start ing f rom rest
- The integral starting assist helps you when
driv ing by automat ically releasing the parking
brake ¢
page 78, Starting from rest.
-When sta rting on inclines , the starting assist
prevents the vehicle from un intent ionally roll­
ing back. The bra kin g for ce of the par kin g b rake

When stopping at a traffic signal or stopp ing in
city traffic on vehicles with an automatic trans­
miss ion, the park ing brake can be applied . T he
vehicle does not have to be held with the foot ­
brake. The parking brak e eliminates the tendency
to creep with a drive range engaged . As soon as
you dr ive off as usual , the parking brake is re­
leased automatically and the veh icle starts to
move.
Starting on sl opes
When starting on inclines, the star ting ass ist pre­
vents the vehicle from unintentionally rolling back. The braking force of the parking brake is
not released until sufficient driv ing 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 iver's
safety belt is engaged in the buckle.
Starting off w ith a trailer
T o prevent rolling back unintentionally on an in­
cline, do the following:
.,. Keep the switch@q page 77, fig . 92 pulled
and depress the accelerator . The park ing b rake
stays applied and prevents the vehicle from
ro lling bac kward .
.. You can release the switc h @ once you are su re
t h at you a re developing enough driving force at
the whee ls by depressing the acce lerator .
D epending on the weight o f the r ig (veh icle and
trai ler) and the seve rity of the in cli ne, you may
roll backwards as you sta rt. Yo u can prevent roll ­
i n g bac kwards by ho lding the parking brake
switch @ pulled out and acce lerating -just as
you would when starting on a hill with a conven ­
tional hand brake .
Driving
Emergency braking
In the event that the conventional brake system
fails or locks .
.. In an emergency, pull the sw itch @ q page 77,
fig . 92 and continue to pull it to slow your vehi­
cle down with the parking brake .
.. As soon as you release the switch @ or accele r-
ate, the b ra ki ng process stops.
If you pull the switch @and hold it above a
speed of about 5 mph (8 km/h), the emergency braking function is i nitiated . The vehicle is b raked
at all fo ur whee ls by act ivati ng the hydrau lic
brake system. The br ake performan ce is s imi la r
to maki ng a n emergency stop
q &. .
In order not to act ivate the eme rgency braking by
mis take, an aud ib le warn ing tone (buz ze r)
sounds when the swi tc h @ is p ulled. As soon as
the switch @ is re lease d, or the acce le rator pedal
is depressed, emergency braking stops.
A WARNING
=
Emergency braking should on ly be used in an
emergency, when the norma l foot brake has
failed or the brake peda l is obstructed. Us ing
the parking brake to perfo rm emergency brak­
ing will slow your vehicle down as if you had
made a full bra ke application . T he laws of
physics cannot be suspended ev en with ESC
and its a ssociated components (A BS, ASR,
E DS). In co rners and when road o r we ather
conditions are ba d, a f ull brake applica tion
can cause the ve hicl e to skid o r the rear end to
b reak away -risking an accident.
Speed warning system
Overview
The speed warning sys tem helps you to keep your
driving speed below a set speed limit.
The speed warn ing system warns if the driver ex­
ceeds a previous ly s tored maximum speed. A
warning tone will sound as soon as the veh icle
speed exceeds the set speed by about 3 mph
(3 km/h) . At the same time, a warning symbo l
79

Driving
appears in the display . The symbol's appearance
m ight be diff erent in some models.
The speed warning system has two warn ing
thresholds that function independently of each
other and that have somewhat different purpos ­
es:
Speed warning 1
You ca n use speed wa rning 1 to set the maximum
speed while yo u are driving. This setting w ill re­
main in effect unt il you tu rn
off the ignition , as ­
suming that you have not c hanged or reset the
setting .
The . (USA models) /. (Can ada mode ls)
speed war ning symbol in the wa rni ng
1 display
appears when you exceed the maximum speed.
It
goes o ut when the speed fa lls below the stored
maximum speed.
The speed wa rning symbo l w ill also go out if the
speed
exceeds t he stored maximum speed by
mo re tha n about 25 mp h
(40 km/h) for at least
10 seconds. The stored maximum speed is de let ­
ed.
Speed warn ing 2
S toring wa rn ing 2 is recommended if you always
want to be reminded of a certain speed, for ex ­
ample when you are trave ling in a co unt ry that
has a genera l maxim um speed limit, or if you do
not want to exceed a specified speed for w inter
tires .
The . (USA models)
I. (Canada mode ls)
speed warn ing 2 symbo l appears in the disp lay
when yo u exceed the stored speed limit. Unlike
warn ing 1, it will not go out until the veh icle
speed d rops be low the stored speed limit .

Even tho ugh your vehicle is equip ped with a
spee d war ning system, you s ho ul d still watch
the speedometer to make sure you are not
driving faster than t he speed limit.

• Press button @to set that speed.
The stored speed and the green symbol
[lj;(i )~i4 (US model)/ l'I (Canadian model) are
shown in the display ¢
fig. 95. The display may
vary, depending on the type of display in your ve­

The speed is kept constant by modifying engine
power or through an active brake intervention.
A 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 vehicle and
other vehicles.
Driving
- For reasons of safety , cruise control should
not be used in the city, in stop-and-go traf­
fic, on twisting roads and when road condi­
tions are poor (such as ice, fog, gravel, heavy ra in and hydroplaning) - risk of acci­
dent .
- Turn off the cruise control temporarily when entering turn lanes , highway exit lanes or in
construction zones.
- Please note that inadvertently "resting" your foot on the accelerator pedal causes
the cruise control not to brake. This is be­
cause the cr uise control is overridden by the
driver's accele rat ion.
- If a brake system malfunction such as over­
heating occurs when the cruise control sys­
tem is switched on, the braking function in
the system may be switched off . The other
cruise control functions remain active as
long as the ind icator
light til;rnM4 (US mod­
els)
t l'I (Canadian models) is on.
(D Tips
The brake lights illuminate as soon as the
brakes apply automatically.
Changing speed
• To increase/decrease the speed in incremen ts,
tap the lever in the
(£)10 direction ¢ page 81,
fig . 94 .
"'To increase/decrease the speed quickly, hold
the lever in the
010 direct ion until the de­
sired speed is displayed.
You can also press the accelerator pedal down to increase your speed, e.g . if you want to pass
someone . The speed you saved earlier will re­
sume as soon as you let off of the accelerator
pedal.
If, however, you exceed your saved speed by
6 mph (10 km/h) for longer than 5 minutes, the
cruise control will be turned off temporarily . T he
green symbo l in the display turns white. The
saved speed remains the same .
