Electrical System Maintenance

Battery Care
WARNING
Battery posts, terminals and related
accessories contain lead and lead com-
pounds, chemicals known to the State of
California to cause cancer and reproduc-
tive harm. Wash hands after handling.
The electrolyte level on maintenance free
batteries cannot be checked. Periodically,
the condition and the state-of-charge of
each battery should be checked by a Volvo
Truck dealer. Maintenance free batteries do
not require any attention other than keeping
them clean and firmly clamped in place in
their respective trays. Keep the cable con-
nections clean and tight. Check the battery
state-of-charge indicators periodically to
determine battery condition.
Check for worn cables at every major in-
spection. Replace worn cables. Check
battery terminals for cracks.
When disconnecting battery terminals, al-
ways disconnect the ground terminal first.
When reconnecting, always connect the
ground terminal last.
Lighting
Check the lights on the vehicle daily. Re-
place burnt out inserts and bulbs. See next
page for a listing of bulb types. Replace any
broken or cracked side or rear reflectors.
Headlights should be checked for aim at
least once per year.
Maintenance
WARNING
Always wear eye protection when work-
ing around batteries to prevent the risk
of injury due to contact with sulfuric
acid or an explosion.
