Jump starting
If the auxiliary battery is discharged the hybrid system can be started by jump starting. Depending on the the vehicle condition, the engine may not
start.
To avoid serious personal injury and damage to your vehicle which might result from battery explosion, acid burns electrical burns, or damaged
electronic components, these instructions must followed precisely.
If you are unsure about how to follow this procedure, we strongly recommend that you seek the help of a competent qualified technician or towing
service.
CAUTION

and avoid spilling acid on your skin, clothing, or vehicle.
If you should accidentally get acid on yourself or in your eyes, remove any contaminated clothing and flush the affected area with water
immediately. Then get immediate medical attention. If possible, continue to apply water with a sponge or cloth while en route to the medical
office.
The gas normally produced by a battery will explode if a flame or spark is brought near. Use only standardized jumper cables and do not smoke or
light a match while jump starting.
Warning: Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after handling.
The battery used for boosting must be 12V.
Do not jump start unless you are sure the booster battery is correct.
