qInspecting Engine Oil Level
1. Be sure the vehicle is on a level
surface.
2. Warm up the engine to normal
operating temperature.
3. Turn it off and wait at least 5 minutes
for the oil to return to the oil pan.
4. Pull out the dipstick, wipe it clean, and
reinsert it fully.
Full
OK
Low
5. Pull it out again and examine the level.
It's OK between Low and Full.
But if it's near or below Low, add
enough oil to bring the level to Full.
CAUTION
Don't add engine oil over Full. This
may cause engine damage.
6. Make sure the O-ring on the dipstick is
positioned properly before reinserting
the dipstick.
The distance between Low and Full on the
dipstick represents the following:
Oil capacity
L (US qt, Imp qt) 0.75 (0.79, 0.66)
qChanging Engine Oil and Filter
Change engine oil and filter according to
Scheduled Maintenance (page 8-3).
Please act responsibly―protect the
environment and take used oil to a
recycling facility. Ask your dealer or a
service station for information.
WARNING
Handling Used Engine Oil:
Continuous contact with used engine
oil is dangerous. It could cause skin
cancer. Always wash with soap and
water immediately after changing oil
and filter.
CAUTION
Remove any oil splatter from the
exhaust manifold, the exhaust pipe and
the shield. Oil left on these areas will
smoke when the engine is running.
