Roadside Emergencies
JUMP STARTING YOUR VEHICLE
The gases around the battery can explode if exposed to flames,
sparks, or lit cigarettes. An explosion could result in injury or
vehicle damage.
Batteries contain sulfuric acid which burns skin, eyes, and
clothing.
Preparing your vehicle
Also see the label on the battery.
1. Use only a 12–volt supply to start your vehicle. If you connect your
battery to a 24–volt power supply you can damage your starter, ignition
system and other electrical components. Do not attach the jumper cables
to the glow plug relay as this could severely damage the glow plugs,
injector driver module and PCM.
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 disabled vehicle making sure
they do not touch. Set the parking brake on both vehicles and stay clear
of the engine cooling fan and other moving parts.
4. Check all battery terminals and remove any excessive corrosion before
you attach the battery cables. Ensure the vent caps are tight and level.
5. Turn the heater fan on in both vehicles to protect any electrical
surges. Turn all other accessories off.
