🛡️ Safety Features

Safety Features General:

Advanced for its time, including ABS, optional ASR (Acceleration Slip Regulation), and robust chassis construction.

Active Safety:

Anti-lock Braking System (ABS), Acceleration Slip Regulation (ASR - optional).

Passive Safety:

Crumple zones, reinforced passenger cell, dual front airbags (introduced later in the W140 lifecycle, but standard on later models and potentially available as an option on 1992 models depending on market).

💡 Technology Features

Infotainment Features:

Early infotainment systems, likely including an analogue or early digital radio tuner, cassette player. The 'cleaning cassette deck tone head' procedure indicates the presence of a cassette player.

Assistance Systems:

Anti-lock Braking System (ABS), optional Acceleration Slip Regulation (ASR), and the sophisticated self-leveling suspension and active damping (ADS) systems were key technological features.

Connectivity Features:

Limited by modern standards; primarily focused on internal vehicle systems. Antenna mast cleaning suggests radio reception is a key feature.

🔧 Maintenance

Oil Change Interval:

Typically every 10,000-15,000 km or 12 months, whichever comes first (refer to specific manual for exact recommendation and oil type).

Transmission Fluid Interval:

Automatic transmission fluid and filter change generally recommended every 50,000-80,000 km or as specified by Mercedes-Benz.

Engine Oil Type:

API SJ or higher, SAE 0W-40 or 5W-40 synthetic oil is generally recommended for optimal performance and protection (verify with manual).

Automatic Transmission Fluid:

Mercedes-Benz ATF (Automatic Transmission Fluid) specification, typically MB 236.6 or MB 236.7 depending on the specific transmission variant. DEXRON II/III may be compatible but the Mercedes-specific fluid is preferred.

Coolant Type:

Mercedes-Benz approved coolant (e.g., G05 or equivalent), typically a 50/50 mix with distilled water. Phosphate-free and silicate-free coolant is crucial.

Common Problems:

Can include vacuum line leaks affecting central locking and other systems, biodegradable wiring insulation degradation, wear on suspension components, potential for head gasket issues on some M119 variants if overheated, and SRS system warning lights. The W140 is also known for its complexity and potential for electrical gremlins if not properly maintained.
