Underinflation also reduces fuel efficiency
and tire tread life, and may affect the vehicle’s
handling and stopping ability. Please note that
the TPMS is not a substitute for proper tire
maintenance, and it is the driver’s
responsibility to maintain correct tire
pressure, even if underinflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
USA only:
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the
system detects a malfunction, the telltale will
flash for approximately 1 minute and thenremain continuously illuminated. This
sequence will continue upon subsequent
vehicle start-ups as long as the malfunction
exists. When the malfunction indicator is
illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of
incompatible replacement or alternate tires
or wheels on the vehicle that prevent the
TPMS from functioning properly. Always
check the TPMS malfunction telltale after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to
continue to function properly.

warning lamp comes on and warning
messages appear in the multifunction display
while driving. To brake, the driver must then
apply significantly greater brake pedal
pressure and depress the pedal much further
to obtain the expected braking effect. If
necessary, apply full pressure to the brake
pedal. Brakes are only applied to the front
wheels. Stopping distance is increased! For
more information, see “Electro-hydraulic
brake system” in this in this Operator’s
Manual.
If there is a malfunction in the electro-
hydraulic brake system, we recommend that
the vehicle be transported with all wheels off
the ground using flatbed or appropriate wheel
lift/dolly equipment.
If circumstances do not permit the
recommended towing methods, the vehicle
may be towed with all wheels on the ground
or one axle raised only so far as necessary to
have the vehicle moved to a safe location
where the recommended towing methods
can be employed.XSwitch off the tow-away alarm before
towing the vehicle with all wheels on the
ground or one axle raised ( Y page 64).
!
Before towing the vehicle observe the
following instructions:
R Do not tow-start the vehicle. You could
otherwise seriously damage the
automatic transmission which is not
covered by the Mercedes-Benz Limited
Warranty.
R Do not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
R Towing of the vehicle should only be
done using the properly installed towing
eye bolt. Never attach a tow cable, tow
rope or tow rod to the vehicle chassis,
frame or suspension parts.
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.
! Avoid pulling the vehicle abruptly or
diagonally, since it could result in damage
to the chassis alignment.
! Do not use the towing eye bolt for
recovery, as this could damage the vehicle.
If in doubt, recover the vehicle with a crane.
i If the battery is disconnected or
discharged
R the SmartKey will not turn in the starter
switch
R the automatic transmission will remain in
park position P

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

Fuses
Introduction
The electrical fuses in your vehicle serve to
switch off malfunctioning power circuits.
If a fuse is blown, the components and
systems secured by that fuse will stop
operating.
GWarning!
Only use fuses approved by Mercedes-Benz
with the specified amperage for the system in
question and do not attempt to repair or
bridge a blown fuse. Using other than
approved fuses or using repaired or bridged
fuses may cause an overload leading to a fire,
and/or cause damage to electrical
components and/or systems. Have the cause
determined and remedied by an authorized
Mercedes-Benz Center.
A blown fuse must be replaced by an
appropriate spare fuse (recognizable by its
color or the fuse rating given on the fuse) of
the amperage recommended in the fuse
chart. Any Mercedes-Benz Center will be glad
to advise you on this subject.
iIn case of a blown fuse contact Roadside
Assistance or an authorized Mercedes-
Benz Center.
If a newly inserted fuse blows again, have the
cause determined and rectified by an
authorized Mercedes-Benz Center.
The fuse chart is located in the trunk with the
vehicle tool kit (Y page 224). The fuse chart
explains the fuse allocation and fuse
amperages.
Before replacing fuses
