All engines use automatic transmissions--the gas engines a 4 speed, the turbodiesel a 5 speed. Antilock 4-wheel disc brakes are standard. Side airbags aren't offered. Power-adjustable pedals are available on all models. Rear-obstacle detection is available on all but the base XLS. Rear DVD entertainment is available on all but XLS and XLS Limo. For 2004, the optional telescoping trailer-tow mirrors gain integrated turn signals. Maximum towing capacity is 11,000 lb.
