Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is off.
Wear safety gloves and goggles.

2. Check Engine Oil Level

Open the hood and locate the dipstick.
Pull out the dipstick, wipe it clean, reinsert, and remove again to check the oil level.
If low, add the appropriate type and amount of oil as specified in the owner’s manual.

3. Inspect Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Check if the fluid is below the minimum mark.
If low, top it up with the recommended brake fluid type.
Inspect the brake lines and components for any signs of leaks.

4. Inspect Cooling System

Check the coolant reservoir level.
If low, add the correct coolant mixture as specified in the owner’s manual.
Inspect for any visible leaks in hoses, radiator, or water pump.

5. Check Battery Condition

Inspect battery terminals for corrosion and ensure they are tightly connected.
Use a multimeter to check battery voltage; it should be around 12.6 volts when fully charged.
If the battery is weak, replace it with a compatible unit.
