CHECKING THE COOLANT LEVEL
1. Stand the vehicle on a level surface.
TIP
• Place the vehicle on a suitable stand.
• Make sure the vehicle is upright.
2. Check:
• Coolant level
The coolant level should be between the
maximum level mark “a” and minimum level
mark “b”.
Below the minimum level mark → Add the
recommended coolant to the proper level.
NOTICE

• Adding water instead of coolant lowers the
antifreeze content of the coolant. If water is
used instead of coolant check, and if nec-
essary, correct the antifreeze concentra-
tion of the coolant.
• Use only distilled water. However, if dis-
tilled water is not available, soft water may
be used.
3. Start the engine, warm it up for several min-
utes, and then turn it off.
4. Check:
• Coolant level
TIP
Before checking the coolant level, wait a few
minutes until it settles.
