Preface

Introduction of the New A-Class, Model Series 176

Dear Reader,

With this Introduction into Service Manual we are

introducing the new A-Class, model series 176.

The purpose of this brochure is to acquaint you with

the technical highlights of this new vehicle in advance

of its market launch. This brochure is intended to

provide information for people employed in service,

maintenance/repair and 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 Xentry Diagnostics.

WIS is updated continuously. Therefore, the informa-

tion available there reflects the latest technical status

of our vehicles.

The Introduction into Service Manual provides initial

information on the on the new A-Class, model series

176. The Introduction into Service Manual is not

stored in this form 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 technical data, equipment

and options is valid as of the copy deadline in April

2012 and may therefore differ from the current

production configuration.

Brief description

Overview

Introduction of the New A-Class, Model Series 176 b

Vehicle concept

The A-Class in model series 176 is based on a new

concept, which differs fundamentally from the

previous A-Class model series 169.

The transversally installed engine is no longer

mounted above the front axle, but ahead of it. The

multilink rear suspension provides high responsive-

ness with high driving safety and high comfort.

Numerous special equipment options such as

driving assistance systems make the new A-Class

especially comfortable while also enhancing its

safety level.

Dimensional concept

The change in concept is particularly apparent

when the vehicle dimensions are compared with the

predecessor. The vehicle length has been extended

by 409 mm, the wheelbase by 131 mm. The width

of the vehicle has grown by 16 mm while the vehicle

height has been reduced by 160 mm.
