Engine Specifications
|
|
Primary Engine
|
|
Engine Type:
|
Likely V8 gasoline or inline-6 gasoline/diesel, depending on specific W463 sub-model in 1997. Specific engine codes (e.g., M112, M119, OM602, OM603) would be detailed in the manual.
|
|
Performance
|
|
Typical Power Output:
|
Varies significantly by engine. For example, the G500 (W463) likely featured a 5.0L V8 producing around 237-296 hp, while diesel variants would have lower output.
|
|
Fuel System
|
|
Fuel Delivery:
|
Fuel injection systems (e.g., Bosch KE-Jetronic or later EIS/ME systems for gasoline, mechanical injection for diesel), detailed in the manual.
|
|
Cooling System
|
|
Cooling Type:
|
Liquid-cooled, pressurized system. Manual will detail radiator, coolant types, thermostat, and pump specifications.
|
|
Lubrication System
|
|
Oil Type And Capacity:
|
Manual will specify required engine oil viscosity grade (e.g., 10W-40, 15W-40 for diesel) and API service classification, along with oil filter part numbers and capacity. Example: MB 229.1 or MB 228.3 for diesel.
|
|
Transmission
|
|
Standard
|
|
Type:
|
Likely a 4-speed automatic (e.g., 722.6 '5G-TRONIC' for some petrol models) or 4/5-speed manual transmission for diesel variants. The manual covers all variants.
|
|
Optional
|
|
Optional Transmission:
|
Depending on engine and market, both automatic and manual transmissions were available. Specific gear ratios and transfer case details are covered.
|
|
Features
|
|
Transfer Case:
|
Permanent all-wheel drive with a lockable center differential and often lockable front and rear differentials, all operationally detailed in the manual.
|
|
Fluid Specifications
|
|
Automatic Transmission Fluid:
|
Manual will specify the correct ATF type, likely a Dexron-III equivalent or specific MB approval fluid for the 722.6 transmission (e.g., MB 236.10).
|
|
Manual Transmission Fluid:
|
Manual will specify the appropriate gear oil viscosity and API rating (e.g., SAE 75W-90 GL-4/GL-5).
|
|
Safety Features
|
|
Ratings
|
|
Crash Test Information:
|
While formal NHTSA/Euro NCAP ratings for this era are less common, the robust body-on-frame construction and advanced for its time safety features provided significant passive safety. The manual covers SRS system diagnostics.
|
|
Active Features
|
|
Braking System:
|
Four-wheel disc brakes. Anti-lock Braking System (ABS) was standard. Manual covers ABS system components, testing, and repair.
|
|
Traction Control:
|
Some models may have featured ASR (Acceleration Slip Regulation) as an early form of traction control. Manual will detail its operation and diagnostics.
|
|
Passive Features
|
|
Supplemental Restraint System:
|
Driver and front passenger airbags (SRS). Manual details airbag module replacement, sensor diagnostics, and fault finding.

Maintenance
|
|
Service Intervals
|
|
Oil Change Interval:
|
Typically every 7,500 to 15,000 miles (12,000 to 24,000 km) or 12 months, depending on engine oil type and driving conditions. Manual will provide specific factory recommendations.
|
|
Transmission Fluid Change:
|
Automatic transmissions often recommended fluid changes every 30,000-60,000 miles. Manual will specify exact intervals and procedures.
|
|
Other Maintenance:
|
Includes spark plug replacement, air filter replacement, coolant flush, brake fluid replacement, differential fluid changes, and transfer case fluid changes at specified intervals detailed in the manual.
|
|
