Enviromental protection
Have the high-voltage battery disposed of in
an environment-friendly manner by an
authorized Mercedes-Benz Center. G
Warning!
The HYBRID system is energized by high
voltage. The components of the HYBRID
system are indicated by yellow warning
labels. High-voltage cables are orange-
colored.
You could be seriously or even fatally injured
when you
R tamper with components or high-voltage
cables of the HYBRID system
R touch components or high-voltage cables
of
the HYBRID system after the vehicle has
been involved in an accident
R touch damaged components of the HYBRID
system
Do not remove the high-voltage battery of the
HYBRID system. Have the high-voltage
battery disposed of in an environment-
friendly manner by an authorized Mercedes-
Benz Center. Operating safety
G
Warning!
When your vehicle is in electric drive mode the
engine produces significantly lower noise
levels. Other motorists or pedestriants,
especially those who are visually or hearing
impaired,

may be unable to hear your vehicle
while it is in motion. This is particularly true
when driving at lower speeds and during
parking maneuvers. At all times, it is the
responsibility of the driver to be aware of their
surroundings, especially in these low speed
situtations. Otherwise other road users could
be seriously or fatally injured. G
Warning!
Have all work on the vehicle, especially safety-
related work, work on safety-relevant
systems,

work on the HYBRID system as well
as maintenance work, carried out by an
authorized Mercedes-Benz Center.
i For more information on operating safety,
refer to the Operator’s Manual. Vehicle modifications
G
Warning!
Improper work on the HYBRID system or
modifications
of the vehicle can cause vehicle
systems to cease functioning properly. You
could lose control over the vehicle and cause
an accident.
Therefore, have work on the HYBRID system
and modifications of the vehicle such as
installation or modification of vehicle
equipment carried out by an authorized
Mercedes-Benz Center
i For more information on operating safety,
refer to the Operator’s Manual. Proper use of the vehicle
Proper
use of the vehicle requires that you are
familiar with the following information and
rules:
R the safety precautions in this manual
R the “Technical data” section in this manual

Rims and tires
i The ML 450 HYBRID does not have a spare wheel.
Vehicles equipped with 19" wheels come with MOExtended tires. MOExtended tires have
run-flat
characteristics. The 17" and 18" wheels listed in this section do not have tires with
such run-flat characteristics. When replacing factory-equipped 19" wheels with 17" or 18"
wheels, retrofitting with TIREFIT is strongly recommended.
For information on MOExtended tires and TIREFIT, refer to the Operator’s Manual. Model ML 450 HYBRID
