JUMP STARTING
(LOW VOLTAGE [UNDERHOOD] BATTERY ONLY)
WARNING:The gases around the battery can explode if
exposed to flames, sparks, or lit cigarettes. An explosion could
result in injury or vehicle damage.
WARNING:Batteries contain sulfuric acid which can burn skin,
eyes and clothing, if contacted.
Do not attempt to push-start your automatic transmission
vehicle. Automatic transmissions do not have push-start
capability. Attempting to push-start a vehicle with an automatic
transmission may cause transmission damage.
Preparing your vehicle
If your low voltage (underhood) battery becomes disconnected or
disabled for any reason, the vehicle controller must relearn the engine’s
operating characteristics in order to operate it at maximum efficiency.
This relearning process occurs the first time the vehicle is driven after
reconnecting the low voltage battery. If the learning procedure does not
have time to complete during the drive, the engine will continue to
operate for 3-5 seconds after you turn the ignition off to complete the
relearning process. This is a normal condition and will not re-occur until
the low voltage battery is disconnected again. The brake system must
also be reset. Refer toLow voltage (underhood) batteryin the
Maintenance and Specificationchapter for more information.
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 vehiclesdo nottouch. 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 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.
