The Cadillac XT5 has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Q3 doesn’t offer knee airbags.
Over 200 people are killed each year when backed over by motor vehicles. The XT5 (except Luxury) offers optional Reverse Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Q3 doesn’t offer automatic braking for stationary objects directly to the rear.
Both the XT5 and the Q3 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available all wheel drive, blind spot warning systems, around view monitors and rear cross-path warning.
