Air Filter Restriction Gauge
The air filter restriction gauge is in the upper housing of the air filter assembly.
Check the air filter restriction gauge whenever you open the hood to carry out general engine maintenance or at least every
7,500 mi (12,000 km). If you operate your vehicle in extremely dusty conditions, check the gauge at least every
500 mi (800 km) or two weeks, whichever occurs first. Change the air filter element when the restriction gauge reads near the change filter line and the gauge is yellow. Allowing the restriction gauge to reach maximum affects engine performance and fuel economy.
Operating your vehicle in heavy snowfall or extreme rain conditions may allow excessive amounts of snow or water into the air intake system. This could restrict air flow and cause the engine to lose power or shut down.
After installing a new air filter element, you must reset the gauge by pressing the reset button.
After operating your vehicle during heavy snowfall or extreme rain, do the following:- Snow: At the earliest opportunity, open the hood and clear any snow and ice from the air filter housing inlet and reset the air filter restriction gauge.
- Extreme rain: The air filter element dries out after approximately 15–30 minutes of driving at highway speeds. At the earliest opportunity, open the hood and reset the air filter restriction gauge.
Note:
Do not remove the foam filter.
