Both the Santa Fe Hybrid and Grand Highlander have child safety locks to prevent children from opening the rear doors. The Santa Fe Hybrid has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Grand Highlander’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
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 Santa Fe Hybrid are reminded to check the back seat when a sensor determines the back seat is occupied. The Grand Highlander doesn’t offer a back seat reminder.
To help make backing out of a parking space safer, the Santa Fe Hybrid has standard Rear Cross-Traffic Collision Warning with Rear Cross-Traffic Collision-Avoidance Assist, systems which detect vehicles approaching from the sides and can automatically apply the brakes to prevent a collision. Only the Grand Highlander Limited/Platinum offers Parking Support Brake.
Both the Santa Fe Hybrid and the Grand Highlander have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, front wheel drive, 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, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors, available all wheel drive and around view monitors.
