Safety notes

WARNING

Some safety systems only function when the engine is running. You should therefore never switch off the engine when driving. Otherwise, the safety systems of your vehicle may not function correctly and as a result will no longer protect you and other persons as intended. In addition, there is a risk that you may lose control of your vehicle and thus cause an accident.

WARNING

If you drive over obstacles at high speed or if the vehicle bottoms out in rough terrain, it could cause heavy impacts to the vehicle underbody, tyres or wheels. This could cause your vehicle to be damaged, which in turn might lead to an accident. This also applies to vehicles which are equipped with underbody protection.

You should therefore drive over obstacles slowly. Prevent the vehicle from bottoming out when driving off-road and if necessary, have your vehicle inspected at a qualified specialist workshop.

WARNING

Always have work on the vehicle carried out by a qualified specialist workshop. In particular, work relevant to safety or on safety-related systems as well as maintenance work must be carried out at a qualified specialist workshop. The workshop must have the necessary specialist knowledge and tools to carry out the work required. Mercedes-Benz recommends that you use a Mercedes-Benz Service Centre for this purpose.

WARNING

Work carried out incorrectly, or alterations made to the vehicle, e.g. re-routing of cables under coverings, could cause the safety systems of your vehicle to stop working properly. The safety systems would thus no longer protect you and other persons as intended. In addition, there is a risk that you may lose control of your vehicle and thus cause an accident.

All work and alterations to the vehicle, e.g. installations or modifications, should therefore be carried out at a qualified specialist workshop.

WARNING

If work on electronic equipment and its software is carried out incorrectly, this equipment could stop working. The electronic systems are networked via interfaces. Tampering with these electronic systems could cause malfunctions in systems which have not been modified. Malfunctions such as these can seriously jeopardise the vehicle's operating safety and therefore your own safety.

You should therefore have all work and modifications to electronic components carried out at a qualified specialist workshop.

Registering your vehicle

Mercedes-Benz may ask its Service Centres to carry out technical inspections on certain vehicles to improve their quality or safety.

Mercedes-Benz can only inform you about vehicle checks if it has your registration data.

It is advisable to register your vehicle with a Mercedes-Benz Service Centre. Inform Mercedes-Benz as soon as possible about any change of address or vehicle ownership.

Digital speedometer and total distance recorder

Do not attempt to modify the electronically stored total distance reading for the vehicle by tampering with the electronics.

If the total distance reading has been altered and you subsequently sell the vehicle but do not inform the buyer, this may constitute a punishable offence under local legislation.

Changing the engine power output

Any tampering with the electronic engine management system in order to increase the engine power output will lead to the invalidation of the vehicle's general operating permit and its insurance cover as well as to the loss of warranty entitlements.

Changes in power output require the vehicle to be recertified and must be reported to the vehicle insurers. Tyres, suspension, brakes and cooling systems must be adapted to the increased engine power output.

Increases in engine power can:

• change the emission values

• cause malfunctions

• cause consequential damage

The operating reliability of the engine is not guaranteed in all cases.

If the power output of the vehicle's engine has been modified and you subsequently sell the vehicle but do not inform the buyer, this may constitute a punishable offence under local legislation.

BlueTec® exhaust gas aftertreatment

The BlueTec® exhaust gas aftertreatment system must be operated in conjunction with the reducing agent AdBlue® if it is to function correctly. AdBlue® is not topped up during maintenance work. Therefore, top up the AdBlue® tank regularly during vehicle operation.

Topping up and operating the vehicle with AdBlue® are necessary in order to comply with emissions regulations, and are therefore a condition of the vehicle's operating permit. Operating the vehicle without AdBlue® will lead to the invalidation of its operating permit. The legal consequence of this is that the vehicle will no longer be permitted to be operated on public roads.

This may be a criminal offence or breach of road traffic regulations in certain countries. Special concessions granted either at the time of purchase or to reduce operating costs, e.g. reduced taxes or road charges, may also be rendered invalid retroactively. This may be the case in both the country of registration and in other countries where the vehicle is operated.

If the AdBlue® reservoir is empty or there is a malfunction, the engine diagnostics indicator lamp in the instrument cluster lights up more. The engine output may be automatically reduced the first time the vehicle comes to a standstill[1]. Adapt your driving style accordingly and drive with particular care. Top up the AdBlue® tank immediately. In the event of a malfunction, have the BlueTec® exhaust gas aftertreatment system checked and repaired at a qualified specialist workshop.

Mercedes-Benz recommends that you use a Mercedes-Benz Service Centre for this purpose.

Attachments, bodies, equipment and conversions

Mercedes-Benz recommends genuine Mercedes-Benz parts and conversion parts and accessories that have been approved by Mercedes-Benz expressly for the type of vehicle concerned.

These parts have been specially tested to establish their safety, reliability and suitability.

For safety reasons, have bodies manufactured and fitted in accordance with the valid Mercedes-Benz body/equipment mounting directives. These body/equipment mounting directives ensure that the chassis and the body form one unit and that maximum operating and road safety is achieved.

For safety reasons, Mercedes-Benz recommends that:

• no other modifications be made to the vehicle.

• approval be obtained from Mercedes-Benz in the event of deviations from approved body/equipment mounting directives.

  Approval from certified inspection agencies or official approvals cannot rule out risks to your safety.

You may obtain further information from any Mercedes-Benz Service Centre.
