Note:Inspect the wheel pilot hole
prior to installation. If there is
visible corrosion in wheel pilot hole,
remove loose particles by wiping
with clean rag and apply grease.
Apply grease only to the wheel pilot
hole surface by smearing a “dime”
(1 square cm) sized glob of grease
around the wheel pilot surface (1)
with end of finger. DO NOT apply
grease to lugnut/stud holes or
wheel-to-brake surfaces.
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 Fuel™ system. 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
1. Connect the positive (+) jumper cable to the positive (+) terminal of
the discharged battery.
Note:In the illustrations,lightning boltsare used to designate the
assisting (boosting) 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 the ground stud
located toward the front of the vehicle (forward of the battery) on the
radiator support. Keep the negative (-) cable away from the battery and
the carburetor/fuel injection system.
Note:Do not attach the negative (-) cable fuel lines, engine rocker
covers, the intake manifold or electrical components asgrounding
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.
5. Ensure that the cables are clear of fan blades, belts, moving parts of
both engines, or any fuel delivery system parts.
