The recommended tire pressure for a 2018 Jeep Wrangler JL is typically 35 PSI for both front and rear tires, but always check the placard on the driver's side door jamb for specific information.
For optimal performance, it's recommended to change the oil every 5,000 to 7,500 miles depending on driving conditions and oil type. Always refer to the owner's manual for specific maintenance intervals.
Use Mopar Antifreeze/Coolant 10 Year/150,000 Mile Formula OAT (Organic Additive Technology) or equivalent. Do not mix with other types of coolants.
Turn the ignition to the "On" position without starting the engine. Press the gas pedal slowly three times within 10 seconds. Turn the ignition off, then start the engine to check if the light is reset.
If the check engine light comes on, check for any obvious issues such as a loose gas cap. If the problem persists, have the vehicle scanned for trouble codes at a service center.
To improve fuel efficiency, maintain proper tire pressure, remove excess weight, drive conservatively, and perform regular maintenance such as oil changes and air filter replacements.
