Accessory Inflator
Your vehicle may have an accessory inflator system.
You can inflate things like basketballs and bicycle tires.
You can also use it to bring your tire pressure up to
the proper pressure. The engine must be running and
the gearshift lever must be in P (Park) for the inflator to
operate.
The accessory inflator
is located in the rear
compartment on the
passenger’s side of the
vehicle.
The accessory inflator kit
includes a hose and
three nozzle adapters.
To use the accessory inflator, do the following:
1. Attach the appropriate nozzle adapter to the end of
the hose.
2. Attach that end of the hose to the object you wish
to inflate.
3. Remove the dust cover and attach the hose to the
outlet.
