Always read and heed all WARNINGS below.
- Hybrid drive: read the important information concerning a dead high voltage battery under.
- Turn off the ignition and all electrical consumers.
- Make sure the area is well ventilated when you charge the battery.
- Open the engine hood.
- Remove the cover 1 by pressing on the arrow > fig. 202.
- Open the cover 2 on the positive terminal.
- Connect the charger connectors according to the instructions to the jump start bolts. (Bolts under the cover = "positive", Bolts with hex head = "negative").
- Only now plug the mains lead for the charging equipment into the wall outlet and turn it on.
- Make sure the charging rate is not over 30 amps/14.8 Volt
- When the battery is fully charged: Turn the charging equipment off and remove the mains lead from the wall outlet.
- Now remove the clamps for the charging equipment.
- Close the cover 2 on the positive terminal and re-install the cover 1.
- Close the hood.
A discharged battery can freeze at temperatures of only 32 ºF (0 ºС). Allow a frozen battery to thaw completely before attempting to charge it. However, we recommend not using a thawed battery again because the battery casing can be cracked due to ice formation and can leak battery acid.
Battery charging (Maximum charging rate of 30 amps/14.8 Volt)
When charging at low voltages (e.g. with a trickle charger), the battery cables do not have to be disconnected first. The battery caps should not be opened when charging a battery.
It is not necessary to remove the battery from the luggage compartment.
Fast charging the battery (charging rate above 14.8 Volts)
For technical reasons do not use a battery charger that uses voltage greater than 14.8 Volts to charge your vehicle's battery.
WARNING
Charging a battery can be dangerous.
- Always follow the operating instructions provided by the battery charger manufacturer when charging your battery.
- Never charge a frozen battery. It may explode because of gas trapped in the ice. Allow a frozen battery to thaw out first.
- Do not reuse batteries which were frozen. The battery housing may have cracked and weakened when the battery froze.
- Charge the battery in a welt ventilated area. Keep away from open flame or electrical spark. Do not smoke. Hydrogen gas generated by the battery is explosive.
- To reduce the danger of explosion, never connect or disconnect charger cables while the charger is operating.
- Fast charging a battery is dangerous and should only be attempted by a competent technician with the proper equipment.
- Battery acid that may spill during charging should be washed off with a solution of warm water and baking soda to neutralize the acid.
Note
Never use a fast charger as a booster to start the engine. This will seriously damage sensitive electronic components, such as control units, relays, radio, etc., as well as the battery charger.
