Preface

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 Introduction 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 production configuration.

Brief description

Cab-behind-engine vehicles with all-wheel drive

With the Zetros, Mercedes-Benz is continuing its tradition of cab-behind-engine vehicles with allwheel drive.

The new cab-behind-engine vehicles with all-wheel drive from Mercedes-Benz are designed to meet the following requirements of a modern specialpurpose 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 advantages 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

Technical design

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 redesigned cab, allows the vehicle to meet the specific requirements placed on a modern special-purpose vehicle.
