• Selector lever must be in position P (and handbrake applied) when checking/adjusting CO or
idle speed
• CO should be checked/adjusted when engines is warm and idling
• CO content outside check values shown below = adjust to specified setting value
• CO content within check values need not be adjusted provided engine is operating satisfactorily

Notes:
1) Unleaded fuel only. Can be run on 91 octane unleaded . • RON stands for Research Octane Number, and is a measure of the ability of the fuel to withstand knocking. MON stands for Motor Octane Number, another way of measuring the same property .
(R+M)/2, also called AKI (Anti Knock Index) is a combination of these two measurements . 95 RON is equivalent to 91 (R+M)/2. 91 RON is equivalent to 87 (R+M)/2 .
