brief period of increased noise because oil
pressure must first build up in the hydraulic
valve adjusters. This is normal and not a cause
for concern.
If the engine should not start immediately,
the starting process is automatically stopped
after a short time. Repeat starting procedure.

Electromechanical
parking brake
Operation
The electromechanical parking brake replaces
the hand brake.
Fig. 82 Center console: Park ing brake
.. Pull on the switch<®> c> fig . 82 @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
t ime to release the parking brake. The indi­
cator light in the switch goes out.
Your vehicle is equipped with an electrome­
chan ical parking brake. The parking brake is
designed to prevent the vehicle from roll ing
un intent ionally 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
i ng brake
c> page 82, Starting from rest.
On the road 81
- When start ing on inclines, the starting as­
sist prevents the vehicle from unintentional­
ly rolling back. The braking force of the
parking brake is not released until sufficient
driving force has been built up at the
wheels.
Emergency brake function
An emergency brake ensures that the vehicle
can be slowed down even if the
normal brakes
fail
c> page 83, Emergency braking.
Indicator lights
-If the parking brake is closed with the igni­
tion
switched on the indicator lights come
on - (USA mode ls)/ . (Canada models)
in the instrument cluster and the switch.
- If the parking brake is closed with the igni­
tion
switched off the indicator lights come
on - (USA models)/ . (Canada models)
in the instrument cluster and the switch for
about 20 seconds .
A WARNING
Do not press the accelerator pedal inadver­
tently if the veh icle is stationary but the
engine is running and a gear is selected .
Otherwise the vehi cle w ill start to move
immediately and could result in a crash.
(D Note
If the symbol . in the display or the indi­
cator light
11111 (USA models)/ . (Cana­
da models) in the instrument cluster flash­
es, there is a malfunction in the brake sys­
tem. Please refer to the detailed descrip­
tion of the indicator lights
c>page 14.
- If the indicator light -(USA mod-
els)/ . (Canada models) or
Im turns
on, there may be a malfunction in the
parking brake
c> page 15.
{I) Tips
-Yo u can app ly the parking brake at any
time -even with the ignition switched
off. The ignition must be on in order to
release the parking brake.

Depending on the weight of the r ig (vehicle
and trai ler) and the severity of the incline, you
may roll backwards as you start. You 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 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(®) and
continue to pull it to slow your vehicle down
with the parking brake.
... As soon as you release t he sw itch (®) or ac-
ce lerate, the braking p rocess stops.
If you pull the sw itch(®) and hold it above a
speed of about 5 mph (8 km/h), t he emergen­
cy braking fu nction is in itiated . The vehicle is
b raked at all four wheels by activating the hy­
d ra u lic bra ke system. The b rake performance
i s simi lar to making an emergency stop
c::> &. .
In order not to activate the emergency brak­
ing by m ista ke, an audible warning tone (b uz­
z er) sou nds when the switch®> is pulled. As
soon as the switch(®) is released, or the acce l­
erator pedal is dep ressed, 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 brake to perform emer­
gency braking will slow you r vehicle down
as if you had made a fu ll brake applicat ion.
T he laws of physics can not be s uspended
even w ith ESP 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 -
r isking an accident.

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
are exceeding the maximum speed that you
have set. You will hear a warning tone when
you r speed exceeds the stored value by ap­
proximately 3 mph (3 km/h) . An indicator
li ght . (USA
models) ;a (Canada mode ls) in
the instr ument cluster d isp lay al so tur ns on at
the same time. The indicator light . /.
turns off when the speed decreases be low the
stored maxim um speed .
Se tting a t hreshold is recommended if you
would like to be rem inded w hen you reach a
certain maximum speed. Situations where you
may want to do so incl ude driv ing in a co untry
with a genera l speed limit or if there is a
specified maximum speed for winter tires.
(D Tips
Even though your vehicle is eq uipped w ith
a speed warn ing system, you sho uld still
watch the speedometer to make sure you
are not dr iv ing faster than the speed limit.
Setting the threshold
You can set, change and delete the threshold
in the MMI.
... Select: !CAR ! function button > Car systems
contro l button > Dri ver ass ist > Speed warn­
ing .
You can set any threshold between 20 mph
(30 km/h) and 150 mph (240 km/h) . Sett ings
can each be adjusted in increments of 5 mph
(10 km/h).

The speed is kept constant
via an engine out­
put adjustment or active brake intervention .
8_ 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 contro l
should not be used in the city, in stop­
and-go traffic, on twisting roads and
when road conditions are poor (such as ice, fog, gravel, heavy rain and hydro­
plan ing) - risk of accident.
- Turn off the cruise control temporarily when enter ing 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
because the cruise control is overridden
by the drive r's acceleration.
- If a brake system malfunction such 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 control functions re­
main active as long as the indicator light
m:lmi (US models)/ . (Canadian mod­
els) is on.
(D Tips
The brake lights illuminate as soon as th e
brakes decelerate automatically.
Changing speed
"' Press lever in the 0 or O direction
c::>page 84, fig. 83 to increase or decrease
your speed.
"' Release the lever to save that speed .
Change speed in increments of 1 mph (1 km/
h) by lightly press ing the lever. If you keep the
lever pressed down , you will alter your speed
in 5 mph (10 km/h) increments .
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 resume as soon as you release the acceler­
ator pedal.
If, however, you exceed your saved speed by
6 mph (10 km/h) for longer than 5 minutes,
the cruise control will turn off temporari ly.
