Your vehicle is equipped with an electrome
chanica l parking brake . The parking brake is
des igned to prevent the vehicle from ro lling
un intent ionally and replaces the hand brake.
I n 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 integral starting assist helps you when
driving by automatically releasing the park
ing brake ¢
page 90, 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 .

can be slowed down even if the

- Occasional noises when the pa rking

.,. Stop the vehicle with the foot brake .
.,. Pull the switch to apply the parking brake.
.,. Move the selector lever to P .
.,. Turn the engine off¢.&_.
In addit ion on incline s and grades
.,. Turn the steering wheel so that yo ur vehicle

start to move.
A WARNING
--When you leave your vehicle -even if on-
ly briefly -always remove the ignition
key. Th is applies pa rticularly when chil
dren remain in the vehicle. Otherwise the
children could sta rt the eng ine, release
the par king brake or operate electrical
equ ipment (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 applicat ion.
The laws of physics cannot be suspended
even w ith ESC and its associated compo
nents (ABS, ASR, EDS) . In corners and
when road or weather conditions are bad, a full b rake application can cause the vehi
cle to skid or the rear end to break away -
risking an accident.

- The hood is closed.
- The vehicle must have been dr iven faster
than
2.5 mph (4 km/h) since the last stop.
- A trailer is not hitched to the vehicle.
A WARNING
- Never turn off the engine before the ve

full funct ion of the brake boos ter and the
power steering is not gua ranteed. You
m ust use more force to tu rn or brake if
necessary. Beca use you cannot steer and

[IJ indic ator light
appears in the instrument cluster display
and - also appears in the trip com
puter .
.. When you take your foot off the brake ped
al, the engine restarts. The indicator light
turns off .
Additional information
The engine will switch off in the P, 0/5 and N
positions as well as in manual mode. In the P
position, the engine will also remain off if you
take your foot off the brake pedal. The engine
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 eng ine will start aga in .
Shift from 0/5 to P qu ickly to prevent the en
g ine from starting unintentionally when shift
ing through R.
You can determine for yourself if the engine
will stop or not by reduc ing 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 tu rning, the eng ine will not switch off
when the vehicle is stationary. As soon as you
press the brake down harder, the engine will
switch off.
(D Tips
-Press the brake pedal during a stop
phase to keep the vehicle from rolling.
- When you stop and the start-stop-sys
tem turns the engine off, the ignition re
mains on. Make sure that the ignition is
switched off before exiting the vehicle.
- The ignition will turn off if you press the
!START ENGINE STOPI * button during a
stop phase.
- The image in the display is slightly differ

Charging the batteries
Applies to vehicles: with hybrid drive
The vehicle is equipped with two 12 volt bat
ter ies and a h igh voltage battery.
If the
12 volt batter ies are dead, they may be
charged with a charger or the vehicle may be
jump started with assistance from another ve
hicle in the same way as a conventional vehi
cle .
The same applies to the high voltage battery
if it is d ischarged . However, in this case, the
charg ing process is accompanied w ith mes
sages in the inst rument cluste r display. The
i gnit ion m ust be switched on and all unneces
sary electric components m ust be turned off.
The connections in the engine compartment
are used for both charging and jump starting
c::> page 245 or c::> page 284.
Vehicle not ready to start. See owner's
manual
This message appears if the high voltage bat
tery charge level is too low. The vehicle can no

high voltage battery must be charged with a
charger or the vehicle must be jump started
with the aid of another vehicle.
Afte r the connecting the cha rger or jumper ca

charging or the vehicle is being jump started
with assistance from another vehicle.
If the 12 vo lt batteries are dead, the -
indicator light turns on. The charging proce

This may happen if the charger or the battery
in the veh icle that is assist ing is too weak.
If
the vehicle cannot be started, see an author
ized repa ir facility for assistance .
(D Tips
- The charger should deliver a current of at
least
30 A. Otherwise charging the high
voltage battery will take considerably longer. A current between
50 A and 70 A
is ideal.
- The ve hicle that is assist ing should be
somewhat within the same vehicle class
when jump starting a vehicle. A smaller
vehicle's battery may be drained.
- After approximately
30 minutes, the
c harging procedure ends because the ig
nition is automatically turned off.
If you
would like to continue to charge the bat
tery, turn the ignition on again.
