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 to30 miles (50 km) and at a speed not to exceed
30 mph (50 km/h). For more information, see
“Towing the vehicle”.Display messagesPossible causes/consequences and 0050 Solutions0027

Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and lead to death. Do not
run the engine in confined areas (such as a
garage) which are not properly ventilated.Display messagesPossible causes/consequences and 0050 Solutions0026Brake WearThe brake pads have reached their wear limit.XHave the brake pads replaced as soon as possible.
!
Brake pad thickness must be visually inspected by a qualified technician at the intervals
specified in the Maintenance Booklet.
GWarning!
Have brake pad replacement and other work
on the electro-hydraulic brake system carried
out by qualified technicians only. Contact an
authorized Mercedes-Benz Center for further
information.
The electro-hydraulic brake system must be
deactivated prior to working on the system.
High pressure is intermittently built up in the
system as part of its automatic self-test.
In addition, the system is automatically
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 position 1 or the
KEYLESS-GO start/stop button is pressed
once, when the brake pedal is depressed or
when the parking brake is released. Failure to
deactivate 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.238Vehicle status messages in the multifunction displayPractical hints

Because the ESP ®
operates
automatically, the engine and ignition must
be shut off (SmartKey in starter switch
position 0 or 1 or KEYLESS-GO start/stop
button in position 0 or 1) when the vehicle
is being towed with the front axle raised.
Active braking action through the ESP ®
may otherwise seriously damage the brake
system which is not covered by the
Mercedes-Benz Limited Warranty.
Towing with all wheels on the groundGWarning!
If circumstances require towing the vehicle
with all wheels on the ground, always tow with
a tow bar if:
R the engine will not run
R there is a malfunction in the electro-
hydraulic brake system
R there is a malfunction in the power supply
or in the vehicle’s electrical system
This is necessary to adequately control the
towed vehicle.
Prior to towing the vehicle with all wheels on
the ground, make sure the SmartKey is in
starter switch position 2.
GWarning!
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
vehicle. Adapt your driving accordingly.
XMake sure the ignition is switched on.XWith the vehicle at a standstill, depress the
brake pedal and keep it pressed.XShift the automatic transmission into
neutral position N.XRelease the brake pedal.XIf engaged, release the parking brake.XSwitch on the hazard warning flasher

!
The vehicle may be towed only for
distances up to 30 miles (50 km) and at a
speed not to exceed 30 mph (50 km/h).
i While being towed with the hazard
warning flasher in use, use the combination
switch in the usual manner to signal turns.
Only the selected turn signal will operate.
Upon canceling the turn signal, the hazard
warning flasher will operate again.
