Which engine oil viscosity does the Toyota 4Runner recommend as the best choice for fuel economy and cold starts?
SAE 0W-20. SAE 0W-20 (ILSAC GF-5) is recommended. If it is unavailable, 5W-20 may be used, but it must be replaced with 0W-20 at the next oil change. Maintenance data (fuel, oil level, etc.)

On your 4Runner the starter turns slowly, the headlights are dim and the horn is weak. What is the likely cause?
Discharged battery or loose/corroded terminals. Slow cranking with dim lights and a weak horn points to a discharged battery or loose or corroded terminals. If the starter cranks normally but the engine won't start, think fuel, flooding or immobilizer. If the engine will not start

When installing the 4Runner's air conditioning filter, how must the "↑UP" marks on it point?
