Engine Oil
Checking Engine Oil
It is a good idea to check the engine oil level at eachfuel fill. In order to get an accurate reading, the oil mustbe warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. SeeEngine Compartment Overviewon page 7!16for thelocation of the engine oil dipstick.
1. Turn off the engine and give the oil several minutesto drain back into the oil pan. If this is not done, theoil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towelor cloth, then push it back in all the way. Remove itagain, keeping the tip down, and check the level.

Windshield Wiper Fuses
The windshield wiper motor is protected by a circuitbreaker and a fuse. If the motor overheats due to heavysnow, etc., the wiper will stop until the motor cools.If the overload is caused by some electrical problem,have it fixed.
Power Windows and Other Power
Options
Circuit breakers protect the power windows and otherpower accessories. If the current load is too heavy, thecircuit breaker opens and then closes after a cool downperiod, protecting the circuit until the problem is fixed orgoes away.
Fuses and Circuit Breakers
If the vehicle is a Two-mode Hybrid, see the Two-modeHybrid manual for more information.
The wiring circuits in the vehicle are protected fromshort circuits by a combination of fuses, circuit breakersand fusible thermal links. This greatly reduces thechance of fires caused by electrical problems.
Look at the silver-colored band inside the fuse. If theband is broken or melted, replace the fuse. Be sure youreplace a bad fuse with a new one of the identical sizeand rating.
If you ever have a problem on the road and don't havea spare fuse, you can borrow one that has thesame amperage. Just pick some feature of your vehiclethat you can get along without–like the radio orcigarette lighter–and use its fuse, if it is thecorrect amperage. Replace it as soon as you can.
