Maintenance
Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
• If the battery becomes discharged in a
short time (because, for example, the
headlights or interior lights were left on
while the vehicle was not in use),
recharge it by slow charging (trickle)
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.

ed accessories contain lead and
lead compounds, chemicals known

for a long time in the low temper-
