BATTERY RECHARGING
Your vehicle has a maintenance-free,
calcium-based battery.
• If the battery becomes discharged in
a short time (headlights or interior
lights were left on while the vehicle
was not in use), recharge it by slow
(trickle) charging for 10 hours.
• If the battery gradually discharges
because of high electric load while
the vehicle is being used, recharge it
at 20-30A for two hours.
