Take great care when fitting spark plugs not 
to cross-thread plug, otherwise costly 
damage to cylinder head will result. It is 
essential that correct grade of spark plugs 
are fitted. Incorrect grade of spark plugs 
may lead to piston overheating and engine 
failure. Use only approved spark plugs, use 
of unapproved spark plugs may cause the 
misfire detection system to malfunction.

1. Disconnect battery earth lead.

±

 

0.05 mm (0.040 

±

 0.002 in).

Do not attempt to clean or adjust gaps. If a 
spark plug problem exists, try substituting 
defective spark plug(s) with new one(s).

CAUTION: Do not attempt to clean or adjust 
spark plug gaps.  If a spark plug problem 
exists, try substituting the defective spark 
plug with a new one.
