Rotation Pattern Guide
FWD: Front to rear straight, rear cross to front
RWD: Rear to front straight, front cross to rear
AWD/4WD: Full X-pattern every 5,000–7,500 mi
Staggered: Side-to-side only if non-directional tires
Recommended rotation interval: every 5,000–7,500 miles. Rotate with every other oil change for best results.
❄ Winter Prep
✓ Check antifreeze concentration (minimum -34°F protection)
✓ Test battery — cold temps reduce capacity 30–60%
✓ Verify tire tread depth (4/32" minimum for snow traction)
✓ Service AWD/4WD differential and transfer case fluids
✓ Replace wiper blades and refill washer fluid (-20°F rated)
✓ Test heater, front/rear defroster, and heated seats if equipped
✓ Inspect fuel lines and check for water in fuel system
☀ Summer Prep
✓ Check coolant level and test radiator cap pressure seal
✓ Inspect serpentine belt for cracking or glazing
✓ Test A/C system output and replace cabin air filter if needed
✓ Check tire pressure — heat increases PSI (recheck cold in a.m.)
✓ Inspect brake pads and rotors before summer road trips
✓ Check transmission fluid color and level
✓ Top off all fluids: brake, power steering, coolant, washer
