Mercedes G-Class Maintenance Guide for UAE Owners

The Mercedes G-Class is built to handle tough roads, luxury driving, and powerful performance. However, driving in the UAE means your vehicle faces extreme heat, sand, and heavy traffic almost every day. Regular servicing is the best way to keep it reliable and protect its long-term value.

A proper Mercedes G-Class maintenance plan for UAE owners includes regular engine oil changes, oil filter replacement, brake inspections, and coolant checks. It also covers battery testing, AC servicing, transmission maintenance, and fluid top-ups. 

Tire rotation and suspension inspections are equally important to keep the vehicle safe, stable, and reliable. It also includes replacing air filters, cabin filters, brake fluid, differential oil, and transmission oil at the recommended intervals. 

Following the factory service schedule and adding extra care for UAE weather helps prevent expensive repairs. Consistent maintenance also improves safety, fuel efficiency, and driving comfort.

Why Is Regular Maintenance More Important in the UAE?

The UAE has one of the toughest driving environments for any luxury SUV. Summer temperatures often go above 45°C, while fine desert sand and stop-and-go traffic place extra pressure on important vehicle systems. High heat affects engine oil, coolant, batteries, and air conditioning performance faster than in cooler countries.

Regular servicing helps every part work as designed despite these conditions. Small issues like engine oil leaks, low coolant, dirty filters, or worn belts can quickly become expensive repairs if ignored. 

Preventive maintenance also keeps the engine running smoothly, protects expensive components, and reduces the chance of unexpected breakdowns during daily driving.

Understanding the Mercedes ASSYST PLUS Service System

Mercedes-Benz uses the ASSYST PLUS maintenance system to monitor your vehicle’s condition. Instead of depending only on mileage, the system also checks driving habits, engine operating conditions, and service history before reminding you when maintenance is needed.

When a service reminder appears, it should not be ignored. The system is designed to help owners perform maintenance before wear becomes serious. 

Following these reminders keeps the engine properly lubricated, reduces unnecessary component wear, and helps maintain the overall reliability of the vehicle throughout the year.

Different Types of Mercedes Maintenance Services

Service A: The First Scheduled Maintenance

Service A is usually required after one year or around 10,000 km, whichever comes first. This is considered the basic maintenance service that keeps the vehicle operating efficiently during normal use.

The service normally includes synthetic engine oil replacement, oil filter replacement, brake inspection, tire pressure adjustment, and topping up important fluids such as coolant, washer fluid, and brake fluid if needed. Technicians also perform a general inspection to identify early signs of wear before they develop into larger mechanical problems.

Service B: More Complete Preventive Care

Service B is normally performed every two years or around 20,000 km. It includes everything completed during Service A but adds several important maintenance items that improve vehicle reliability over the long term.

During Service B, technicians replace the cabin air filter, change the brake fluid, inspect additional safety components, and carry out a more detailed inspection of the vehicle. Fresh brake fluid improves braking performance, while a clean cabin filter helps maintain healthy airflow and supports the air conditioning system during the hot UAE summer.

Additional Maintenance Beyond Factory Service Intervals

Some vehicle parts require attention at longer mileage intervals. These services are equally important because they protect major mechanical systems from long-term damage and expensive repairs.

Around every 40,000 km, the engine air filter should be replaced. AMG models may also require new spark plugs during this period. 

The differential oil should also be changed to protect the gears from wear. At approximately 50,000 km or 4 years, replacing the automatic transmission oil and filter helps maintain smooth gear changes and extend transmission life.

List of Major Mercedes G-Class Services

1. Quality of Engine Oil 

The engine produces significant heat during daily operation. In UAE conditions, high temperatures cause engine oil to break down more quickly, reducing its ability to lubricate moving components properly.

Using the correct fully synthetic oil recommended by Mercedes-Benz helps reduce friction, improve cooling, and protect internal engine parts. Delaying oil changes allows contaminants to build inside the engine, increasing wear on bearings, pistons, and timing components. 

Fresh engine oil is one of the simplest ways to improve engine durability and maintain strong performance.

2. Cooling System Maintenance for Extreme Heat

The cooling system works harder in the UAE than in many other countries. Radiators, coolant hoses, water pumps, cooling fans, and thermostats must all operate correctly to prevent engine overheating.

Coolant should always remain at the proper concentration because it removes heat efficiently while protecting internal components from corrosion. Regular inspection of hoses, radiator fins, and coolant levels helps detect leaks before they become serious. 

Preventive cooling system maintenance greatly reduces the risk of overheating during long summer drives.

3. Air Conditioning Care Is Essential

A strong air conditioning system is necessary for both comfort and safety in the UAE. The AC system operates almost every day, placing heavy demand on the compressor, condenser, refrigerant, and cabin filter.

Annual AC servicing includes checking refrigerant pressure, cleaning the condenser, replacing dirty cabin filters if required, and inspecting the compressor for proper operation. 

A well-maintained AC system cools the cabin faster, reduces unnecessary compressor strain, and improves overall driving comfort throughout the year.

5. Battery Maintenance in Hot Weather

Modern G-Class vehicles contain advanced electronics, multiple control modules, cameras, sensors, and driver assistance systems. All these features depend on a healthy battery for reliable operation.

High temperatures shorten battery life by increasing internal chemical reactions. Many batteries in the UAE last only two to three years. 

Testing battery health every six months allows technicians to detect weak batteries before they fail unexpectedly. Clean battery terminals and proper charging also help improve battery performance.

6. Tire and Suspension Inspection

The Mercedes G-Class is heavier than many SUVs and has a high center of gravity. These characteristics place additional stress on tires, suspension parts, wheel bearings, and steering components during daily driving.

Rotating and balancing tires every 5,000 to 10,000 km promotes even tire wear and improves handling. 

Regular suspension inspections help identify worn bushings, shock absorbers, ball joints, and control arms before they affect driving stability. Proper wheel alignment also improves tire life and fuel efficiency.

7. Off-Road Driving Requires Extra Attention

Many owners enjoy taking the G-Class into desert areas, but sand creates additional maintenance needs after every off-road trip. Fine sand particles can enter moving components, cooling vents, and underbody areas if left uncleaned.

Cleaning the undercarriage removes sand that may cause corrosion or damage suspension parts over time. Differential fluids, axle seals, and underbody protection should also be inspected after dune driving. 

Proper cleaning prevents unnecessary wear and keeps the four-wheel-drive system operating efficiently.
