Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off and cool.
Gather tools and parts needed for inspection and repairs.

2. Fluid Inspection

Tools Required: Oil dipstick, coolant reservoir gauge.
Check engine oil level with the dipstick. If low, top off with the manufacturer's recommended oil type.
Inspect coolant levels in the reservoir. If low, add a 50/50 mixture of coolant and distilled water.

3. Brake System Inspection

Tools Required: Jack, jack stands, lug wrench.
Lift the front of the vehicle and secure it with jack stands.
Remove the front wheels to access brake components.
Inspect brake pads and rotors for excessive wear or glazing.
If pads are worn, replace them with OEM or quality aftermarket parts.

4. Electrical Component Check

Tools Required: Multimeter.
Inspect wiring harnesses and connectors for signs of melting or damage.
Use a multimeter to test for shorts or irregularities in electrical circuits.

5. Cabin Air Filter Replacement

Tools Required: Screwdriver (if applicable).
Locate the cabin air filter housing, usually behind the glove box.
Remove the old filter and inspect for debris or blockage.
Replace with a new filter according to the manufacturer's specifications.
