Accessory Inflator
Your vehicle may be equipped with an accessory inflator
system. You can inflate things like basketballs and
bicycle tires. Also, you can 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
is located in the spare tire
cover pocket. The kit
includes a hose and three
nozzle adapters.
To use the accessory inflator, attach the appropriate
nozzle adapter to the end of the hose if required. Then
attach that end of the hose to the object you wish to
inflate. Remove the dust cover and attach the hose to
the outlet.
