If the issue persists, it is recommended to refer to the repair manual for further troubleshooting steps.

If a power window in your Infiniti J30 is not functioning properly, start by checking the fuse associated with the window circuit.

The engine air filter in an Infiniti J30 should be replaced every 12 months or 12,000 miles, whichever comes first. However, in dusty or polluted environments, it is advisable to check the filter more frequently and replace it if it appears dirty or clogged. Regularly replacing the air filter helps maintain engine performance and improves fuel efficiency.

To ensure even tire wear and prolong the life of your tires, it is recommended to rotate them every 6,000 to 8,000 miles. This helps distribute the wear more evenly across all four tires and promotes better handling and traction. Additionally, tire rotation can often uncover potential alignment or suspension issues that may need attention.

For an Infiniti J30, it is recommended to use a high-quality ethylene-glycol based coolant with a mixture of 50% coolant and 50% distilled water. This coolant should meet the specifications outlined in the owner's manual. It is important to never mix different types of coolant or use plain water, as it can lead to cooling system problems.

The recommended oil for an Infiniti J30 is a high-quality synthetic or conventional oil with the viscosity of 5W-30. It is important to use oil that meets the specifications outlined in the owner's manual. Regular oil changes, using the correct oil, help ensure optimal engine performance and longevity.
