Note any changes in the sound of the exhaust or any smell of exhaust fumes in the vehicle.

Check for vibrations in the steering wheel. Notice any increased steering effort or looseness in the steering wheel, or change in its straight ahead position.

Notice if your vehicle constantly turns slightly or "pulls" to one side when traveling on smooth, level road.

When stopping, listen and check for unusual sounds, pulling to one side, increased brake pedal travel or "hard-to-push" brake pedal.

If any slipping or changes in the operation of your transmission occurs, check the transmission fluid level.

Check manual transmission operation, including clutch operation.

Check the parking brake.

Check for fluid leaks under your vehicle (water dripping from the air conditioning system during or after use is normal).
