Electromechanical
parking brake
Operation
The ele ctromechanical parking brake replaces
the hand brake.

> Pull on the switch @ c::> fig. 107 to apply the
parking brake. The indicator light in the
sw itch illuminates .
.,. Step on the brake pedal or the accelerator
pedal and press the switch at the same t ime
to re lease the park ing brake. The indicator
light in the sw itch goes out .
Your vehicle is equipped with an electrome­ chanical parking brake . The parking brake is
designed to p revent the veh icle from rolling
u nintentionally and replaces the hand b rake. .,..

In addition to the norma l functions of a tradi­
tional hand brake, the electromechanica l
parking brake provides various convenience
and safety functions.
When start ing f rom re st
- T he integ ral starting assist helps you when
driving by automatically releasing the park ­
ing brake ¢
page 98, Starting from rest.
-When starting on inclines, the starting as­
sist prevents the vehicle from unintentional­
l y rolling back. The braking force of the
parking brake is not released until sufficient
driv ing force has been built up at the
wheels .
Emergenc y bra ke function
An emergency brake ensures that the vehicle
can be slowed down even if the
normal brakes

A WARNING
If a gear or a drive range (automat ic trans­
m ission) is engaged with the vehicle sta­
tionary and the engine run ning, you must
in no inst ance accelerate o r release the
cl utch carelessly. Otherwise the veh icle
wi ll start to move immediately -risk of an
accident.
CJ) Note

di dealer or other qualified workshop
¢page 30.
(D Tips
-You can apply the parking brake at any
time -even with the ign ition turned off.
The ignit ion must be turned on in order
to release the par king b rake .
- Occasional noises when the parking
brake is applied and released are normal
and are not a cause fo r conce rn.
- When the vehicle is parked, the park ing
brake goes throug h a self-test cycle at
regu lar inte rva ls. Any associated noises
are normal.
Parking
Various rules apply to prevent the parked ve­
hicle from rolling away accidentally.
Parking
"' Stop the vehicle with t he foot brake .
"' Pull the switch to apply the parking brake.
"' Automatic transmission*: Move the selector
lever to
P .
"' Tur n the engine off¢_&.
"' Ma nual transmiss ion: Shift into 1s t gear.
In addition on inclines and grades
"' Turn the steering wheel so that your vehicle
w ill roll aga inst the curb in case it shou ld
start to move.
A WARNING
- When you leave you r vehicle -even i f on­
ly briefly -always remove t he ignition
key. This app lies pa rticularly when chil­
dren remain in the vehicle. Otherwise t he
children could start the eng ine, release
the park ing brake or operate electrical
equ ipme nt (e.g. power windows). There
is the risk of an acc ident.

Using the parking brake to perform emer­
gency braking will slow your vehicle down
as if you had made a full brake application.
The laws of physics cannot be suspended
even w ith ESP and its associated compo­
nents (ABS, ASR, EDS). In corne rs and
when road or weather conditions a re bad,
a full brak e application can cause the vehi­
cle to skid or the rear end to break away -
r isking an accident.
Driver messages in the instrument
cluster
Caution: Vehicle parked too steep
This message appears when the park ing brake
is applied on an incline that exceeds about
30%.
In this case the braking power of the parking
brake may
not be adequate to prevent the ve­
hicle from rolling unintentionally .
Press brake pedal to release parking brake
This driver message appears when the switch
to release the parking brake was pressed. The
parking brake can only be released if you step
on the brake pedal and at the same time press
the switch or you automatically release the
parking brake with the start ing ass ist

Passi ng anoth er vehicl e
If you move into the passi ng lane and no veh i­
cle is detected ahead, the adaptive cruise con­
trol accelerates to the speed you have set and maintains it.
Overrid e
You can increase your speed at any t ime by
stepp ing on the acce lerator pedal. After yo u
re lease the accelerator pedal, the system ad­
justs back down to the speed you previously set .
@ Tips
Please note that the amount of accelera­
tion the adaptive cruise control uses de­ pends on the Distance setting selected.
DISTANCE 1 gives you accelerat ion that is
dynamic and sporty . DISTANCE 4, o n the
other hand, g ives more moderate accelera­
tion . For more information about the time
intervals ¢
page 106, How is the distance
(time interval) set?.
- Please note that if the adaptive cruise
control has begun braking the vehicle
and the driver chooses to brake the vehi­
cle add itionally, the brakes may fee l
"hard" . This is simply due to the pressure
build- up of the initial braking.
- Adaptive cruise control is sw itched off af ­
ter pressing the footbrake . The speed
saved up this point can be resumed. To resume the saved speed, release the
brake pedal and pull the control lever
