5. Checking coolant level
WARNING
To avoid serious injury or death:
• Do not remove radiator cap while coolant is hot.
When cool, slowly rotate cap to the first stop
and allow sufficient time for excess pressure to
escape before removing the cap completely.

cargo bed.
2. Check to see that the coolant level is between the
[FULL] and [LOW] marks of recovery tank.
(1) Recovery tank (A) [FULL]

3. When the coolant level drops due to evaporation,
add water only up to the full level. In case of
leakage, add antifreeze and water in the specified
mixing ratio up to the full level.
(See Flushing cooling system and changing coolant
on page 72.)
