NEW FOR 2011: - Off-Road trim line renamed PRO-4X - SE trim line renamed SV - Exterior colours: Lava Red and Trail Green added - Interior colours: Steel/Graphite added For 2011, the Nissan Xterra undergoes two name changes. The mid-range Off-Road trim is now called the PRO-4X, while the top-line SE trim line is now the SV. The features in the trim lines are unchanged. Based on the F-Alpha platform that it shares with the Nissan Titan and Armada, the Xterra uses a 4.0-litre V6 engine. The S and PRO-4X trim lines come with a six-speed manual transmission that can be optioned to a five-speed automatic. The SV uses the automatic exclusively. All models feature four-wheel drive with a switch-operated, two-speed transfer case. Features on the S include 16-inch alloy wheels, air conditioning, tubular roof rack with covered gear box, crossbars and air dam, tubular step rails, rear bumper steps, front tow hook, heated mirrors, privacy glass, tire pressure monitoring system, power windows with auto-down driver’s side, power locks with keyless entry, cruise control, variable intermittent wipers, rear wiper, cargo net, cargo channel system with tie-downs, first-aid kit, cloth seats, 60/40 split-folding rear seat, and CD stereo. The PRO-4X adds fog lights, Bluetooth connectivity, auto-dimming rear-view mirror with compass, fold-flat front passenger seat, leather-wrapped steering wheel, and six-CD/MP3 stereo with auxiliary input and wheel-mounted audio controls. Also unique to the PRO-4X trim line are electronic locking rear differential, Bilstein PRO-4X performance shock absorbers, roof-rack-mounted PRO-4X lights, and skid plates, and it does not have tubular side rails. When ordered with the automatic transmission, the PRO-4X also includes transmission cooler, hill descent control, hill start assist and XM satellite radio. The SV adds 17-inch alloy wheels, body-colour mirrors and door handles, satin chrome front grille and lower bumper, trip computer, and XM satellite radio.
