• What is Star View?

• Is the car wash included?
Yes. The car wash, interior vacuum and tyre shine are complimentary and part of the OMR 56 price, so there is nothing extra to pay when you collect your Mercedes-Benz.

• Why is an engine oil and filter change included?
Engine oil lubricates the moving parts of your engine, reduces friction and heat, and carries away dirt and debris. A new filter keeps the fresh oil clean.

• Why is brake fluid replaced?
Brake fluid absorbs moisture from the air over time, which reduces braking efficiency and its ability to handle extreme heat. Replacing it keeps your brakes responding as they should.

• Why does my Mercedes-Benz need an electronic diagnostic test?
Modern Mercedes-Benz vehicles rely on advanced electronics. The test reads stored fault codes and system irregularities that may not trigger a warning light, so issues are found before they become expensive repairs. Results can be discussed with your Service Representative in necessary.

• Why are the coolant checks important in Oman?
Coolant stops your engine overheating in hot weather and protects internal parts from corrosion. Even a small leak can lower the level enough to cause overheating.

• Why check the A/C, wipers and washer fluid?

The A/C check confirms effective cooling and clean airflow. Good wiper blades and fresh washer fluid keep your windscreen clear of dust, sand and rain.

• Why inspect the undercarriage, suspension, steering and bodywork?
The undercarriage is exposed to road debris, heat and moisture, so its inspection finds leaks, damage or corrosion that cannot be seen from above. The suspension and steering checks identify wear early, and the bodywork inspection spots visible damage before it spreads.
