While accelerating gently, pay attention to the shift quality of the 5-speed automatic transmission. In cars of this age, it is common to consider whether a transmission fluid service or a conductor plate update might be beneficial to maintain smooth gear transitions.
Find a safe, loose surface to engage the 4WD High and Low ranges via the dash selector. Check this by listening for the mechanical engagement of the vacuum-operated front hubs; if engagement feels sluggish, you might eventually need to budget for an inspection of the vacuum lines or seals.
Drive over a series of small bumps or an uneven road surface and listen for subtle knocks from the front end. On heavier SUVs like the Rexton, it is often wise to consider that sway bar links or control arm bushings may show wear, which can typically be addressed during routine maintenance.
Observe the rear-view mirror during a firm acceleration once the engine is at operating temperature. If you notice significant dark smoke, it may suggest that the EGR system or intake manifold could benefit from a professional clean to maintain engine efficiency.
Standard engine oil and filter change, plus a general safety inspection.
Diesel fuel filter replacement is recommended here to protect the high-pressure common rail system.
Ideal window for a comprehensive automatic transmission fluid and filter service.
Full coolant flush and inspection of all drive belts and tensioners for signs of aging.
Detailed inspection of the timing chain tensioner and a comprehensive health check of the 4WD transfer case lubricants.
Confirm the diesel fuel filter has been replaced recently to ensure the health of the 2.0L e-XDi engine.
Check the tire tread depth and wear patterns; uneven wear often suggests a wheel alignment is due for this 4WD system.
Test all cabin electronics, including the electric seat adjustments and the climate control system's ability to switch air zones.
Inspect the chassis and underbody for signs of heavy off-road use or excessive mud buildup in the frame rails.
Verify that the cooling system pressure is holding and that there are no visible leaks around the radiator plastic end tanks.
Estimated repair costs if issues arise
To keep the Mercedes-sourced gearbox shifting reliably, a full fluid and filter exchange is a proactive measure for high-mileage vehicles.
Depending on the car's history and the quality of fuel used, you might eventually need to budget for professional injector cleaning or calibration to maintain peak fuel economy.
In cars of this weight, the rubber components in the front suspension eventually soften. Replacing these can restore the precision of the steering and ride quality.
If the vehicle has spent most of its life in city traffic, a specialized carbon clean of the particulate filter and EGR valve may be required to prevent future warning lights.
