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.
How often should you rotate tires? You should rotate your tires every 5,000 to 8,000 miles. However, each manufacturer has recommended tire rotation intervals listed in their ownerâs manual, dependent on the vehicleâs design and purpose. If you are advised that the tires on your vehicle need to be rotated before your recommended interval due to their condition, it would be a good idea to heed the recommendation.
