Also, you probably do not have a "pump" as that is an option on the Firestone system, found in the higher priced installs.
As GJ stated the valves will/should be in the rear outside compartments.
Just be careful when airing them up. The bags themselves are small in size, and will air up very quickly if using a compressor. They are rated for a max pressure of 100 psi. When adding air just give the valves small "blips" of air at a time.
Firestons also recommends not to run the rig with NO air in the bags. They recommend a minimum of 20 psi be kept in them.
On our Lexi I run 65-70 psi.
