Cheat CodesIn GTA IV cheats are activated via using the mobile phone. Try entering any of the following codes after Roman has given you his old mobile phone. This happens pretty early in the game so you don't have to wait long before you can enter the cheat codes. Once you have the phone you can enter them as often as you like.
Okay, first get out your mobile phone and press 'Up' to raise the phone higher and reveal the complete keypad. Then use your controller to select the set of numbers according to which cheat you want to use, after you have entered the code the cursor moves to the dial button, just press 'Up' again and if successful you will see a message 'Cheat Activated' on the screen. When a code has been entered correctly, a new 'Cheats' menu option becomes available on your phone under 'Options' which allows you to access the cheats without having to enter the phone number again.
We would say not to save your game after you have enabled a cheat code.

Remove Ammo Limit
When you get 100% completion in the game there is no longer an ammo limit which means you can keep firing away in a gunfight without worrying about how much ammo you have left.
ATM Cash Glitch
Find an ATM then block off traffic in the road leading to it so cars cannot pass. Then wait for someone to use the ATM, kill them then take the money they drop. It's essential at this point that you have done a good job at blocking the roads so the ambulance can not take away the corpse.
With that said... Run a bit away from your victim and go back again and the same money should be available to pick up again... If anyone is using the ATM when you go back you can kill them too and each time you return their cash will have respawned too.
Repair car engine
Broken down? Car on fire? Try calling 911 using your cellphone in the game, the emergency services may come and your engine will be fine again.
