Brake wear

workshop
The brake pads have reached
their wear limit.
Have the brake pads replaced immediately.
!Brake pad thickness must be visually
checked by a qualified technician at the
intervals specified in the Maintenance
Booklet.Warning!
G
Have brake pad replacement and other work
on the electrohydraulic brake system car-
ried out by qualified technicians only. Con-
tact your Mercedes-Benz Center for further
information. The electrohydraulic brake sys-
tem must be deactivated prior to working on
the system. High pressure is intermittently
built up in the system as part of its automat-
ic self-test. In addition, the system is auto-
matically activated when the vehicle is
unlocked by remote control, when the driver
or passenger door is opened, when the
SmartKey in the starter switch is turned to
position1, when the brake pedal is de-
pressed or when the parking brake is re-
leased.
Failure to deactivate the system prior to
maintenance will cause brake pistons to ex-
tend and brake fluid to leak, which may re-
sult in injuries (contusions and acid burns),
see “Electrohydraulic brake system”
(page 84).
344 Practical hintsUnlocking in an emergencyUnlocking the vehicle
Unlocking the trunk
If you cannot unlock the trunk with the
SmartKey, open the trunk with the
mechanical key.
The handle is located above the rear
license plate recess.1Mechanical key locking tab
2Mechanical key
Press locking tab1 in the direction of
arrow and, at the same time, remove
mechanical key2 completely out of
the housing.
Trunk lid lock3Unlocking
Insert the mechanical key in the trunk
lid lock.
Perform the following two steps simul-
taneously:
Turn the mechanical key
counterclockwise to the stop, to
position3.
Pull the trunk lid handle and lift the
trunk lid.
iUnlocking the trunk with the mechani-
cal key will trigger the anti-theft alarm
system when the door is opened.
To cancel the alarm, insert the
SmartKey in the starter switch.
345 Practical hints
Unlocking in an emergency
Unlocking the driver’s door
If you can no longer lock or unlock the
doors using the SmartKey, unlock the driv-
er’s door using the emergency release
catch.The emergency release catch is located on
the left side in the trunk.
1Emergency release catch
Unlock the trunk (
page 344).
Pull emergency release catch1.
The door is unlocked.
Open the door in the normal way.
Notify an authorized Mercedes-Benz
Center.
iUnlocking the driver’s door with the
emergency release catch will trigger
the anti-theft alarm system.
To cancel the alarm, insert the
SmartKey in the starter switch.
iIf it still is not possible to unlock the
door, pull more firmly on the emergen-
cy release catch.
361 Practical hints
Towing the vehicle
Prior to towing the vehicle with all wheels on
the ground, make certain that the SmartKey
is in starter switch position2.
If the SmartKey is left in starter switch
position0 for an extended period of time, it
can no longer be turned in the switch. In this
case, the steering is locked. To unlock, re-
move SmartKey from starter switch and re-
insert.iTo signal turns while being towed with
the hazard warning flasher in use, turn
SmartKey in starter switch to
position2 and activate the combina-
tion switch for the left or right turn sig-
nal in the usual manner – only the
selected turn signal will operate.
Upon canceling the turn signal, the haz-
ard warning flasher will operate again.
Warning!
G
The brake system requires electrical power
to operate.
A malfunction in the vehicle’s power supply
or electrical system may impair brake sys-
tem operation and switch it into its emer-
gency operation mode. To brake, the driver
must then apply significantly greater brake
pedal pressure and depress the pedal much
further to obtain the expected braking ef-
fect. If necessary, apply full pressure to the
brake pedal. Brakes are only applied to the
front wheels. Stopping distance is in-
creased! Adapt your driving style according-
ly. For more information, see
“Electrohydraulic brake system”
(page 84).
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the ve-
hicle. Adapt your driving accordingly.
!Towing of the vehicle should only be
done using the properly installed tow-
ing eye bolt. Never attach tow cable,
tow rope or tow rod to the vehicle chas-
sis, frame or suspension parts.iWhen towing the vehicle with all wheels
on the ground, please note the follow-
ing:
With the automatic central locking acti-
vated and the SmartKey in starter
switch position2 the vehicle doors
lock if the left front wheel as well as the
right rear wheel are turning at vehicle
speeds of approximately 9 mph
(15 km/h) or more.
To prevent the vehicle door locks from
locking, deactivate the automatic
central locking (
page 137).
