from the slot in the hood and return the prop to its re-
tainer.
2. Lower the hood until it approaches about 12 in (30
cm) from the closed position and let it drop.
After closing the hood, be sure the hood is securely
locked.
If this does not close the hood, release it from a slightly
higher position. Do not push the hood forcibly to close
it. It could deform the metal.
Always check that the hood is properly locked
before you start driving. If it is not, it might fly
open while the vehicle is moving and block
your view, which may cause an accident and
serious bodily injury.

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 en-
gine.
2. Pull out the dipstick, wipe it clean, and insert it
again.
3. Be sure the dipstick is correctly inserted until it
stops with the graphic symbol on its top appear-
ing as shown in the illustration. 2.5-liter turbo models

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 upper level.
y Use only engine oil with the recommended
grade and viscosity. y 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 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 en-
gine oil level reading may be in a range between the
upper level and the notch mark. This is caused by ther-
mal expansion of the engine oil.
To prevent overfilling the engine oil, do not add any
additional oil above the upper level when the engine is cold. „ Changing the oil and oil filter
Change the oil and oil filter according to the mainte-
nance schedule in the “Warranty and Maintenance Booklet”.
The engine oil and oil filter must be changed more fre-
quently than listed in the maintenance schedule when
driving on dusty roads, when short trips are frequently
made, or when driving in extremely cold whether.
1. Warm up the engine by letting the engine idle for
about 10 minutes to ease draining the engine oil.
2. Park the vehicle on a level surface and stop the en-
gine.
