Check Engine Light FEATURES AND CONTROLS Your EFI system has an Electronic Control Unit (ECU), which is pre-coded for any potential problems your EFI system will have. If a problem with your EFI system occurs, a code is triggered and the CHECK ENGINE light will come on. If the light comes on, take your Frontier to a qualified Polaris dealer for diagnostic service. Low Oil Pressure Light CAUTION Operating the snowmobile without proper engine lubrication can result in serious engine damage. Always check the oil level on the dipstick when the low oil pressure light illuminates. Add the recommended oil to maintain the oil level between the SAFE and ADD marks on the dipstick. A low oil pressure indicator light will alert you to a low oil condition. When the low oil pressure indicator light is on, visually check the oil level on the dipstick. If the oil level is below the SAFE mark, continued operation will cause serious engine damage. Add the recommended oil before further operation of the snowmobile. See page 124 for the part numbers of Polaris products. CAUTION Mixing brands or using a non-recommended oil may cause serious engine damage. We recommend the use of Polaris Premium 4 Synthetic 0W-40 engine oil for your snowmobile. Never mix brands. 31
