The New Zetros, Introduction into Service Manual for Model Series 949
Dear Reader,
This Introduction into Service Manual presents the
new Zetros, model series 949.
The purpose of this brochure is to acquaint you with
the technical highlights of these vehicles in advance of
their market launch. This brochure is intended to
provide information for people employed in service,
maintenance and repair as well as for aftersales staff.
It is assumed here that the reader is already familiar
with the Mercedes-Benz model series currently on the
market.
In terms of the contents, the emphasis in this Intro-
duction into Service Manual is on presenting new and
modified components and systems.
This Introduction into Service Manual is not intended
as an aid for repairs or for the diagnosis of technical
problems. For such needs, more extensive information
is available in the Workshop Information System (WIS)
and in the Diagnosis Assistance System (DAS).
WIS is updated monthly. Therefore, the information
available there reflects the latest technical status of
our vehicles.
This Introduction into Service Manual presents initial
information relating to the new Zetros in model series
949 and, as such, is not stored in WIS. The contents of
this brochure are not updated. No provision is made
for supplements.
We will publicize modifications and new features in the
relevant WIS documents. The information presented in
this Introduction into Service Manual may therefore
differ from the more up-to-date information found in
WIS.
All information relating to specifications, equipment
and options is valid as of the copy deadline in August
2008 and may therefore differ from the series produc-
tion configuration.

The New Zetros, Introduction into Service Manual for Model Series 949
Overview
Cab-behind-engine vehicles with all-wheel drive
With the Zetros, Mercedes-Benz is continuing its
tradition of cab-behind-engine vehicles with all-
wheel drive.
The new cab-behind-engine vehicles with all-wheel
drive from Mercedes-Benz are designed to meet the
following requirements of a modern special-
purpose vehicle:
• Reliable handling characteristics on all types of
road and off-road
• Safe and ergonomic controls
• Suitable for special deployments and
specialized transport tasks
• Suitable for worldwide deployment in all climate
zones
• Occupant protection
• Tactical and strategic mobility
• Large ground clearance with a large ramp
breakover angle and large approach/departure
angles for excellent off-road capability
As the first example of the new generation of cab-
behind-engine vehicles with all-wheel drive, the
Zetros naturally benefits from all of the other advan-
tages of the cab-behind-engine vehicle concept:
• Well-balanced load distribution for optimal
handling characteristics and steering ability
• Low overall height to facilitate transport by rail
or air, provide a low clearance height and allow
easy entry/exit by occupants
• Easy access to engine and ancillary assemblies
for maintenance and repair
• On military version, optimized distribution of
weight of armor over front and rear axles to
maintain maneuverability and load reserves for
best possible protection

The new Zetros meets the specific requirements of
the current market and is based on tried-and-tested
mass-production technology.
Proven components from the Actros, Atego and
Axor model series have been used on this vehicle to
ensure that general customer requirements for
quality, cost-efficiency and worldwide support can
be met.
The new vehicle concept, particularly the rede-
signed cab, allows the vehicle to meet the specific
requirements placed on a modern special-purpose
vehicle.
