Standard two-wheel drive is adequate for most duties, while available four-wheel drive with a two-speed electronic 4x4 system maximizes handling and control in all weather and road conditions.

Inside the cabin, an available AM/FM stereo with MP3-compatible CD player and auxiliary MP3 input jack provides a decent audio experience and can accommodate your iPod® with ease. In Extended and Crew Cab models, a 60/40 split-bench rear seat offers excellent cargo flexibility. The available DVD entertainment system features an 8” overhead LCD monitor with two wireless headphones and a remote control to entertain rear seat passengers.
