Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to ensure safety.

2. Perform Required Maintenance

A. Oil Change

Gather an oil drain pan, socket set, and a new oil filter.
Remove the oil drain plug using the socket set and allow the oil to drain completely.
Replace the oil filter with a new one.
Reinstall the drain plug and torque it to manufacturer specifications (typically 20-30 ft-lbs).
Fill the engine with the recommended type and amount of oil (refer to the owner's manual).

B. Inspect and Replace Air and Cabin Filters

Locate the air filter housing and remove it.
Replace the air filter with a new one.
Locate the cabin air filter (usually behind the glove box) and replace it.

C. Brake Inspection

Remove the wheel to access the brake components.
Inspect the brake pads for thickness and replace if under 3mm.
Check the rotors for wear and replace if necessary.

D. Tire Inspection

Check tire pressure and inflate as needed.
Inspect tread depth and replace tires if below 2/32".

3. Reset Maintenance Light

Turn the ignition to the "ON" position without starting the engine.
Press the gas pedal three times within 10 seconds.
The maintenance light should reset.
