Roadside Emergencies
Preparing Your Vehicle
Note: Your vehicle has a 12 volt battery that is easily accessible under
the hood. The 12 volt battery controls the switches and contacts that
engage the high voltage battery. The high-voltage battery cannot be
jumped with a standard 12 volt battery. If your high voltage battery
does not accept a regular charge, your vehicle must be towed to your
authorized dealership.
1. Use only a 12 volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle's electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehicles do not touch. Set the parking brake on
both vehicles. Stay clear of the motor cooling fan and other moving parts
on both vehicles.
4. Check all battery terminals and remove any excessive corrosion before
you attach the battery cables. Ensure that vent caps are tight and level.
5. Turn the heater fan on in both vehicles to protect from any electrical
surges. Turn all other accessories off.
Connecting the Jumper Cables
WARNING: Do not connect the end of the second cable to the
negative (-) terminal of the battery to be jumped. A spark may
cause an explosion of the gases that surround the battery or a surge
within the battery.
Note: Do not attach the negative (-) cable to fuel lines, engine rocker
covers, the intake manifold or electrical components as grounding points.
Note: In the illustration, the vehicle on the bottom is used to designate
the assisting (boosting) battery.
