Service and Maintenance
Engine oil must be kept at correct
levels to help ensure proper
lubrication of the vehicle's engine.
It is normal for an engine to use
some oil, and some engines use
more oil when they are new. It is
the owner's responsibility to check
the engine oil level regularly.

Checking the Fluid Level
The best time to check the engine
oil level is when the oil is warm.
To check the oil level, do the
following:
1. Park the vehicle on a level
surface and apply the parking
brake.
2. Stop the engine and wait a
few minutes for the oil to
drain back into the oil pan.
3. Remove the dipstick and wipe
it clean.
4. Reinsert the dipstick all the
way until it is firmly seated.
5. Remove the dipstick again and
check the oil level.
Keep the dipstick pointed
down to get an accurate
reading.
The oil level must be in the
cross-hatched area on the dip-
stick. Add oil as required.
Avoid over-filling the engine
since this may cause engine
damage.
