RUNNING OUT OF FUEL
If you have run out of fuel and need to refill the vehicle with a portable
fuel container, seeRunning out of fuelin theMaintenance and
Specificationschapter for proper fuel filling method using a portable
fuel container and the included fuel filler funnel.Do notinsert the
nozzle of portable fuel containers or any type of aftermarket funnels into
the Easy Fuel“no cap” fuel system as it can be damaged. You must use
the included funnel in such circumstances.
WARNING:Do not insert the nozzle of portable fuel containers
or aftermarket funnels into the Easy Fuelsystem. This could
damage the fuel system and its seal, and may cause fuel to run onto
the ground instead of filling the tank, all of which could result in
serious personal injury.
JUMP STARTING
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
When the battery is disconnected or a new battery is installed, the
automatic transmission must relearn its shift strategy. As a result, the
transmission may have firm and/or soft shifts. This operation is
considered normal and will not affect function or durability of the
transmission. Over time, the adaptive learning process will fully update
transmission operation.
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.
Connecting the jumper cables
Note:In the illustration, the vehicle on the bottom is used to designate
the assisting (boosting) battery.
1. Connect the positive (+) jumper
cable to the positive (+) terminal of
the discharged battery.
2. Connect the other end of the
positive (+) cable to the positive
(+) terminal of the assisting battery.
3. Connect the negative (-) cable to
the negative (-) terminal of the
assisting battery.
4. Make the final connection of the
negative (-) cable to an exposed
metal part of the stalled vehicle’s
engine, away from the battery and
the carburetor/fuel injection system.
Note:Do not attach the negative (-) cable to fuel lines, engine rocker
covers, the intake manifold or electrical components as grounding points.
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.
Ensure that the cables are clear of fan blades, belts, moving parts of both
engines, or any fuel delivery system parts.

Jump starting
1. Start the engine of the booster vehicle and run the engine at
moderately increased speed.
2. Start the engine of the disabled vehicle.
3. Once the disabled vehicle has been started, run both engines for an
additional three minutes before disconnecting the jumper cables.
Removing the jumper cables
Remove the jumper cables in the reverse order that they were
connected.
Note:In the illustration, the vehicle on the bottom is used to designate
the assisting (boosting) battery.
1. Remove the jumper cable from
the ground metal surface.
2. Remove the jumper cable on the
negative (-) terminal of the booster
vehicle’s battery.
3. Remove the jumper cable from
the positive (+) terminal of the
booster vehicle’s battery.
4. Remove the jumper cable from
the positive (+) terminal of the
disabled vehicle’s battery.
After the disabled vehicle has been started and the jumper cables
removed, allow it to idle for several minutes so the engine computer can
relearn its idle conditions.
