Batteries access
To access the batteries, open the left-hand rear door then
remove the skid plate.
Checking the charge state of a maintenance-free battery
The charge indicator on the battery shows the state of
charge of the battery.
If the colour is:
• Green; the charge is correct.
• Black; insufficient charge. Recharge the battery until
the indicator turns green.
• Transparent (colourless); replace the battery as soon
as possible.
Checking the electrolyte level of a maintenance-type battery
Remove the cell caps and check the level in each batteries
cell. The level should be between 10 mm (0.4 in) and
15 mm (0.6 in) above the plates. Add distilled water if
necessary, then install the cell caps.
ATTENTION: When adding distilled water at tempera-
tures below 0 °C (32.0 °F), the batteries must be charged
or the engine run for two hours approximately in order
to ensure that the distilled water and the electrolyte are
properly mixed.
NOTE: Make sure the battery terminals are clean and
coated with grease and that the cables are properly tight-
ened.
