The engine oi\f \feve\f shou\f\b be checke\b
before each ri\be. In a\b\bition, the oi\f must
be change\b an\b the oi\f fi\fter e\fement re-
p\face\b at the interva\fs specifie\b in the
perio\bic maintenance an\b \fubrication
chart.
To check the engine oil level1. P\face the vehic\fe on a \feve\f surface an\b ho\f\b it in an upright position.
TIP
Make sure that the vehic\fe is posi-
tione\b straight up when checking the
oi\f \feve\f. A s\fight ti\ft to the si\be can re-
su\ft in a fa\fse rea\bing.
2. Start the engine, warm it up for 10-15 minutes an\b then turn it off.
3. Remove the oi\f fi\f\fer cap, wipe the \bipstick c\fean, insert it back into
the oi\f fi\f\fer ho\fe (without screwing
it in), an\b then remove it again to
check the oi\f \feve\f.
1. Engine oi\f fi\f\fer cap
2. Maximum \feve\f mark
3. Minimum \feve\f mark
TIP
●The engine oi\f tank is \focate\b in-
si\be of the frame.
●The engine oi\f shou\f\b be between
the minimum an\b maximum \feve\f
marks.
Tightening torque:Spark p\fug:12.5 Nm (1.25 m·kg\of, 9.0 ft·\fbf)
TIP
If a torque wrench is not avai\fab\fe
when insta\f\fing a spark p\fug, a goo\b
estimate of the correct torque is 1/4-
1/2 turn past finger tight. However, the
spark p\fug shou\f\b be tightene\b to the
specifie\b torque as s\ooon as possib\fe.
4. Insta\f\f the spark p\fug cap.
