The base models are decently equipped with items like 16-inch wheels; power windows, locks and mirrors; cruise control; air conditioning; keyless entry; and a CD player. The Sport spices things up with 17-inch polished alloys, sport suspension, foglights, color-keyed grille, chrome exterior trim, power driver seat, leather-wrapped steering wheel and gearshift and a CD player. The Limited features automatic headlights, 17-inch non-polished alloy wheels, heated outside mirrors, a windshield wiper de-icer, power-adjustable front seats, a fold-flat third-row seat, an upgraded JBL sound system and HomeLink. Popular options for the Highlander include a rear-seat DVD-based entertainment system, an in-dash CD changer, a tow package and, on the Limited trim, leather seating and a navigation system.
