CHECKING THE COOLANT LEVEL
1. Stand the vehicle on a level surface.
TIP
• Place the vehicle on a suitable stand.

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.

• Adding water instead of coolant lowers
the antifreeze content of the coolant. If
water is used instead of coolant check,
and if necessary, correct the antifreeze
concentration 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
minutes, and then turn it off.
4. Check:
• Coolant level
TIP
Before checking the coolant level, wait a few
