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 PARK (P) 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.
