Checking the engine oil level using the oil
dipstick
| WARNING Risk of burns from hot component
parts in the engine compartment |
Certain components in the engine compartment
can be very hot, e.g. the engine, the
radiator and parts of the exhaust system.
- Allow the engine to cool down and only
touch component parts described in the
following.
|
Requirements:
- The engine must have an oil dipstick. If not,
the engine oil level can be checked only with
the on-board computer.
Depending on the engine, the oil dipstick may be
installed in the engine compartment in different
locations.
The waiting time before checking the oil level
when the engine is at normal operating temperature
is five minutes.
- Park the vehicle on a level surface.
- Pull oil dipstick 1 out and wipe off.
- Slowly slide oil dipstick 1 into the guide
tube to the stop, and take it out again after
approximately three seconds.
- Oil level is correct: oil level is between 2
and 3.
- Oil level too low: oil level is at 3 or
below.
- Oil level too high: oil level is above 2.
- If the oil level is too low, add 1.1 US qt
(1 liter) of engine oil.
- If the oil level is too high, drain off excess
engine oil. Consult a qualified specialist
workshop.
Checking the engine oil level using the onboard
computer
Requirements
The engine must have an oil level sensor. If not,
the engine oil level can be checked only with the
oil dipstick.
The engine oil level is determined during driving.
Determining the engine oil level can take up to
30 minutes with a normal driving style and even
longer with an active driving style.
In order to receive a result as quickly as possible:
- Warm up the engine
- Park the vehicle on a level surface
- Leave the engine running at idling speed

display is orange and is below "min":
- Add 1.1 US qt (1 l) engine oil.
- Reduce Engine Oil Level and the bar display
for indicating the oil level on the multifunction
display is orange and is above "max":
- Drain off excess engine oil that has been
added. Consult a qualified specialist workshop.
- For Engine Oil Level Switch Ignition On:
- Switch on the ignition to check the engine oil
level.
