Adjust tire pressure:
- Inflate tires to the manufacturer’s recommended pressure.
Replace tires if necessary:
- Remove wheel lug nuts using a socket set and replace worn tires with new ones.
- Torque lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs).

3. Suspension and Alignment Check

Inspect suspension components:
- Examine shocks, struts, and bushings for wear.
- Replace any worn components with OEM parts.
Perform wheel alignment:
- Take the vehicle to a professional alignment shop to ensure proper alignment settings.

4. Traction Control System Reset

Scan for codes:
- Use an OBD-II scanner to check for traction control system fault codes.
Clear codes:
- Follow the scanner instructions to clear any codes.
Test drive:
- Conduct a test drive to ensure that the traction control system is functioning properly.

5. Brake System Inspection

Check brake pads and rotors:
- Inspect for wear and replace if necessary.
- Ensure brake fluid level is adequate; top up with the recommended fluid type.
Test braking performance:
- Take the vehicle for a test drive to ensure consistent braking and no traction loss.
