Suspension revisions designed to provide a softer ride are among the few 2004 changes to Infiniti's crossover SUV. FX is a 5-seat wagon derived from Infiniti's G35 sedan. Two models are offered. The FX35 has a 280-hp V6 and rear-wheel drive or all-wheel drive. The FX45 has a 315-hp V8 and AWD. Both have a 5-speed automatic transmission with manual shift gate. FX's AWD lacks low-range gearing and is not intended for off-roading. For '04, it adds a driver-controlled snow mode to adjust low-speed throttle input and maximize traction. ABS, antiskid/traction control, front torso side airbags, head-protecting curtain side airbags, and xenon headlamps are standard. FX35 comes with 18-inch wheels. A sport suspension with 20-inch wheels is standard for FX45, optional for FX35. Same goes for leather upholstery, heated front seats, power tilt/telescope steering wheel, and driver-seat memory. Rear DVD entertainment, sunroof, and roof rails are optional. So is a Technology Package with a navigation system, adaptive cruise control designed to maintain a set following distance, rearview TV camera, and tire-pressure monitor. The package also includes an "intelligent key" system that allows the driver to unlock the vehicle by pressing buttons on the doors and to start it without inserting the key into the ignition.
