Jump Starting an eCascadia
Warning: Batteries release explosive gas. Do not smoke when working around batteries. Put out all flames and remove all sources of sparks or intense heat in the vicinity of the battery.
Do not allow the vehicles to touch each other. Do not lean over the batteries when making connections. Keep all other persons away from the batteries.
Failure to follow these precautions could lead to severe personal injury as a result of an explosion or acid burns.
Notice: The eCascadia contains two low-voltage systems: 24V and 12V. These directions detail the steps to charge or 'jump start' the 12V batteries. On an eCascadia, the 12V batteries must be operational for the high-voltage batteries to activate.
To jump start another vehicle from an eCascadia, both the 12V and the high-voltage (HV) batteries on the eCascadia must be active. An active high-voltage system is necessary to keep the low-voltage (12V) charge at a sufficient level to provide the 'jump.'
To jump start another vehicle from an eCascadia, follow the directions below, switching out the other vehicle for 'the eCascadia' and 'the eCascadia' for the 'the power source.'
Only use jumper cables approved for use with heavy duty vehicles. The use of inadequate or damaged jumper cables may damage both vehicles.
Do not connect an eCascadia to a vehicle with a different operating voltage. Electronic devices on both vehicles can be damaged if vehicles with different operating voltages are connected.
Note: eCascadia vehicles are equipped with under-hood jump start posts; always connect to these posts instead of the batteries.
When using jumper cables, follow the instructions below.
- Apply the parking brakes and turn off the lights and all other electrical devices.
- Open the hood.
- Connect one end of a 12V positive (+) jumper cable to the
12V positive (+) post on the electric vehicle distribution module
(EVDM) as shown in Fig. .

Positive Post

Negative Post

- Connect the other end of the 12V positive (+) jumper cable
to the 12V positive (+) connection on the power source providing the
jump start. The power source may be a battery, external battery charger, or the jump start post of a vehicle.
- Connect one end of the negative (-) jumper cable to the
negative (-) connection on the power source providing the jump start.
The power source may be a battery, external battery charger, or the jump start post of a vehicle.
- Connect (ground) the other end of the (-) jumper cable to the negative (-) jump start post on the eCascadia as shown, see Fig,.
- Start the power source providing the jump start. This could
mean starting the engine of the vehicle providing the jump start or
turning on an 12V external battery charger. Let the power source run a few minutes to charge the batteries of the vehicle being jump started.
- On the vehicle being jump started, turn the key to the “start” position.
- Once the high-voltage system is enabled, continue to allow the eCascadia to charge until all ICU low-voltage warnings turn off.
- Disconnect the negative (-) (grounded) jumper cable from the negative post on the vehicle that needed the jump start. See Fig. .
- Disconnect the other end of the negative (-) jumper cable from the power source that provided the jump start.
- Disconnect the positive (+) jumper cable from the positive (+) power source that provided the jump start.
- Disconnect the other end of the positive (+) jumper cable from the 12V positive (+) post on the EVDM of the eCascadia. See Fig. .
- Close the hood.
Notice: Always connect the battery, jumper cables, and charger correctly (positive-to-positive, negative-to-negative). Connecting a charging device backwards (positive-to-negative or negative-to-positive) will damage the vehicle.
Warning: Do the next step exactly as instructed and do not allow the clamps of one cable to touch the clamps of the other cable. Otherwise, a spark could occur near a battery, possibly resulting in severe personal injury from explosion or acid burns.
