Texas-Smart Maintenance Intervals
- Every 6 months / 5–7k miles: Oil & filter, tire rotation, multi-point inspection
- Every 12 months: Cabin filter, brake inspection & fluid test, alignment check
- Every 24–36 months: Coolant and brake fluid service (heat & humidity accelerate wear)

severe-duty maintenance plan.
