Solution

1. Tire Inspection

Sub-steps:
1. Check tire tread depth using a tread depth gauge; replace tires if tread is below 3/32 inches.
2. Measure tire pressure with a digital tire pressure gauge; inflate to the recommended PSI as per the owner’s manual.
3. Inspect for any visible damage such as cuts or bulges that may affect traction.

2. Traction Control System Check

Sub-steps:
1. Access the vehicle’s settings through the touchscreen interface.
2. Navigate to the traction control settings and ensure it is enabled.
3. Reset the traction control system if necessary by turning it off and then back on.

3. All-Wheel Drive System Evaluation

Sub-steps:
1. Lift the vehicle using a jack and secure it on jack stands.
2. Inspect the drive shafts and differentials for any signs of wear or damage.
3. Check the fluid levels in the differentials; replace fluid if it is low or contaminated.

4. Suspension Inspection

Sub-steps:
1. Visually inspect all suspension components, including bushings, struts, and control arms for signs of wear.
2. Perform a bounce test on each corner of the vehicle to check for worn shocks or struts.
3. Replace any worn components following manufacturer specifications and torque values.

5. Software Update

Sub-steps:
1. Connect the vehicle to Wi-Fi and check for any available software updates.
2. Follow on-screen instructions to download and install updates, ensuring all systems are functioning properly post-update.
