Police cars
 
 Enter the "Game Options" screen and select the "User Name" option.
 Then, enter "Nfs_Pd" as a player name to unlock most police cars in
 Hot Pursuit mode. Note: "_" indicates a space. 
 
 Helicopter
 
 Enter the "Game Options" screen and select the "User Name" option.
 Then, enter "Whirly" as a player name. If you entered the code
 correctly, the phrase "Cheat Activated" will appear. The Helicopter
 is only available in Test Drive mode. Note: Enabling this code will
 disable the option to save your game.
 
 Heavy car
 
 After selecting your car, press Start to load the race, then before
 the loading screen appears, immediately hold Left + Square + Circle.
 Continue to hold the buttons until the loading screen disappears.

 Turbo boost
 Enable the "Dashboard view" code, then press Up while driving.
 
 Instantly return to road
 After crashing or driving off the road, press Select to instantly return to the road.
 
 Drive any car in any tournament
 Successfully complete all the tournaments. Additionally, select
 "Options" at the car selection screen to choose upgraded opponents.
 
 Bonus cars
 Complete Hot Pursuit mode with each police car to get a new car (BMW
 M5, Corvette, Porsche, Caprice and Lamborghini).
 
 Easy cars and money
 Note: Two memory cards are required for this trick. To perform this
 trick with only one memory card, enter High Stakes mode and the game
 will search port one for a memory card before checking port two. If
 there is no card in port two, the game will prompt you to retry.
 Simply remove the card from port one and insert it into port two to
 have double the cars. You need to own at least one car and have
 enough money (0,000) to buy a new car. Once this is accomplished,
 copy the Need For Speed 4 file to another memory card. While both
 memory cards are in the PlayStation, race in the High Stakes mode and
 have player two intentionally forfeit at the beginning of the race.
 Player one should now have two of the same car. Copy the saved data
 to the other card again and repeat. You can then sell all your cars
 for a large amount of money.  
 
 Easier arrests in Hot Pursuit mode
 Turn your sirens off (L1 + Up) during a hot pursuit as the police and
 the speeder will slow down. Then once you are ready to arrest them,
 turn your sirens back on.
 
 Extra time in Hot Pursuit mode
 Do not enter a name to get more time in single player Hot Pursuit mode. 
 
 Turn signal and headlights
 Hold L1 and press Left or Right to use the turn signals. Hold L1 and
 press Up to turn on the headlights. Hold L1 and press Down to turn on
 the hazard lights.
