Maintenance and service
Engine oil
Checking the oil level
Check the engine oil level at each fuel
stop.
1. Park the vehicle on a level surface and
stop the engine.
2. Pull out the dipstick, wipe it clean, and
insert it again.
3. Be sure the dipstick is correctly insert-
ed until it stops with the graphic
symbol on its top appearing as
shown in the illustration.
1) Notch
2) Upper level
3) Lower level
4. Pull out the dipstick again and check
the oil level on it. If it is below the lower
level, add oil to bring the level up to the up-
per level.
If you check the oil level just after stopping
the engine, wait a few minutes for the oil to
drain back into the oil pan before checking
the level.
Just after driving or while the engine is
warm, the engine oil level reading may be
in a range between the upper level and
the notch mark. This is caused by thermal
expansion of the engine oil.
To prevent overfilling the engine oil, do not
add any additional oil above the upper lev-
el when the engine is cold.
Changing the oil and oil filter
Change the oil and oil filter according to
the maintenance schedule in the “ Warran-
ty and Maintenance Booklet ” .
The engine oil and oil filter must be
changed more frequently than listed in the
maintenance schedule when driving on
dusty roads, when short trips are frequent-
ly made, or when driving in extremely cold
whether.
1. Warm up the engine by letting the en-
gine idle for approximately 10 minutes to
ease draining the engine oil.
2. Park the vehicle on a level surface and
stop the engine.
3. Remove the oil filler cap.
B00467
Use only engine oil with the rec-
ommended grade and viscosity.
Be careful not to spill engine oil
when adding it. If oil touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire. If en-
gine oil gets on the exhaust pipe,
be sure to wipe it off.
