Shunt Malfunction Signs. If your child becomes very ill (persistent vomiting, extreme sleepiness, severe headache), seek medical assistance immediately. Call your childâs doctor if you think that your child is having a shunt malfunction based on the symptoms described above. Remember that you may see only one or two warning signs at a time.
Replace the tires at least every 6 years. If you're not sure, the minimum replacement time that is recommended by the NHTSA is six years regardless of use, with 10 years being the maximum service life for tires. Check your owner's manual for specific recommendations related to your car.
Before rotating your tires, always refer to your vehicle ownerâs manual for rotation recommendations. If no rotation period is specified, tires should be rotated approximately every 5,000 to 8,000 miles. Many vehicle manufacturers recommend replacing all tires on the vehicle at the same time. This makes rotation even more important for maintaining uniform tread depth and optimum tread wear of the entire set.
