Engine oil
Notes on the oil level
Depending on your driving style, the vehicleconsumes up to 0.9 US qt(0.8 liters) of oil per600 miles (1,000 km). The oil consumptionmay be higher than this when the vehicle isnew or if you frequently drive at high enginespeeds.
Depending on the engine, the oil dipstick maybe in a different location.
When checking the oil level:
Rpark the vehicle on a level surface
Rthe engine should be switched off forapproximately five minutes if the engine isat normal operating temperature
Rif the engine is not at normal operating tem-perature, e.g. if the engine was only startedbriefly, wait about 30 minutes before carry-ing out the measurement
