In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Trailseeker are reminded to check the back seat if they opened the rear door before starting out. The ID.4 doesn’t offer a back seat reminder.
The Subaru Trailseeker has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The ID.4 doesn’t offer knee airbags.
The Trailseeker has standard Whiplash-Protection Front Seats, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash-Protection Front Seats system moves the headrests forward to prevent neck and spine injuries. The ID.4 doesn’t offer a whiplash protection system.
To provide maximum traction and stability on all roads, Full-Time Four-Wheel Drive is standard on the Trailseeker. But it costs extra on the ID.4.
When descending a steep, off-road slope, the Trailseeker’s standard Downhill Assist Control allows you to creep down safely. The ID.4 doesn’t offer Downhill Assist Control.
Both the Trailseeker and the ID.4 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.
