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.
We suggest you follow the recommended schedule outlined in your owner's manual, but rotate the tires (and change the oil) at least once a year. You don't have to go to a car dealership to have this done, and many tire dealers and other repair shops will perform both jobs for about $30 total.
