2006 MERCEDES-BENZ E WAGON keyless

97 Safety and Security
Driving safety systems
The electrohydraulic brake system is auto-
matically activated when you:

unlock the vehicle with the SmartKey
or the KEYLESS-GO*


open the driver’s or passenger door


turn the SmartKey in the starter switch
to position1


in vehicles with KEYLESS-GO*, press
the start/stop button on the gear se-
lector lever once


depress the brake pedal


release the parking brake
Warning!
G
The electrohydraulic 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. In such a case, the
red brake warning lamp (
page 374) and
warning messages in the instrument cluster
(
page 383) come on while driving. To
brake, the driver must then apply signifi-
cantly greater brake pedal pressure and de-
press the pedal much further to obtain the
expected braking effect. If necessary, apply
full pressure to the brake pedal. Brakes may
only be applied to the front wheels. Stop-
ping distance is increased!
If there is a malfunction in the electrohy-
draulic brake system, we recommend that
the vehicle be transported with all wheels
off the ground using flatbed or appropriate
wheel lift/dolly equipment. A tow bar must
be used if circumstances do not permit the
use of the recommended towing methods
and the vehicle requires towing with all four
wheels on the ground. Towing the vehicle
with all four wheels on the ground is only
permissible for distances up to 30 miles
(50 km) and at a speed not to exceed
30 mph (50 km/h). For more information,
refer to “Towing the vehicle” (
page 458).

The electrohydraulic brake servo assis-
tance switches off automatically

approximately 2 minutes after you
turned the SmartKey in the starter
switch to position0 or removed the
SmartKey


approximately 2 minutes after you
pressed the KEYLESS-GO* start/stop
button to turn off the engine or power
supply and opened the driver’s door
(with driver’s door open, the starter
switch is set to position 0, same as
SmartKey removed from starter
switch)


approximately 20 seconds after you
locked the vehicle from outside
iIf the electrohydraulic brake system is
activated as the brake pedal is first de-
pressed, you may feel a reduced pedal
resistance and longer pedal travel than
normal. When releasing the pedal, you
may also feel the brake pedal pulsate
and you may hear a sound which is
caused by the activation of the electro-
hydraulic brake system pump. This is
normal and not an indication of a mal-
function. Pedal travel returns to normal
when you release the brake pedal and
the sound soon ceases.
If you experience the above while driv-
ing and the red brake warning lamp
(page 374) illuminates and/or warn-
ing messages appear in the instrument
cluster (
page 383), the brake system
is malfunctioning. Follow the instruc-
tions of the warning message(s) and
have the brake system checked imme-
diately.
Warning!
G
Have brake pad replacement and other work
on the electrohydraulic brake system car-
ried out by qualified technicians only. Con-
tact an authorized Mercedes-Benz Center
for further information. The electrohydraulic
brake system must be deactivated prior to
working on the system. High pressure is in-
termittently built up in the system as part of
its automatic self-test. In addition, the sys-
tem is automatically activated when the ve-
hicle is unlocked by SmartKey, when the
driver or passenger door is opened, when
the starter switch is turned to position
1,
when the brake pedal is depressed or when
the parking brake is released. Failure to de-
activate the system prior to maintenance
will cause brake pistons to extend and brake
fluid to leak, which may result in injuries
(contusions and acid burns). Extended
brake pistons may also cause injury.

100 Safety and SecurityDriving safety systemsWarning!
G
If you see the ESP
® warning lampv
flashing in the speedometer, proceed as fol-
lows:


While driving off, apply as little throttle
as possible


While driving, ease up on the accelera-
tor


Adapt your speed and driving style to
the prevailing road conditions
Failure to observe these guidelines could
cause the vehicle to skid.
The ESP
® cannot prevent accidents result-
ing from excessive speed.
!Do not tow with one axle raised.
Otherwise the transfer case can be
damaged, which is not covered by the
Mercedes-Benz Limited Warranty.
!Performance testing must only be con-
ducted on a two-axle dynamometer.
Otherwise the transfer case can be
damaged, which is not covered by the
Mercedes-Benz Limited Warranty.!Because of the ESP’s
® automatic oper-
ation, the engine and the ignition must
be shut off (SmartKey in starter switch
position0 or1 or KEYLESS-GO
start/stop button* in position0 or1)
when the parking brake is being tested
on a brake test dynamometer.
Active braking action through ESP
®
may otherwise seriously damage the
front or rear axle brake system.
Operational tests with the engine
running can only be conducted on a
two-axle dynamometer.
