The Highlander Limited's optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The X5 doesn't offer pre-crash pretensioners.
For enhanced safety, the front seat shoulder belts of the Toyota Highlander are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW X5 doesn't offer height-adjustable seat belts.
To help make backing safer, the Highlander Limited/Platinum's cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The X5 doesn't offer a cross-path warning system.
Both the Highlander and the X5 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, available crash mitigating brakes, lane departure warning systems, blind spot warning systems and rear parking sensors.
The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH, results indicate that the Toyota Highlander is safer than the BMW X5:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.
For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the Highlander its highest rating: “Top Pick Plus” for 2016, a rating granted to only 73 vehicles tested by the IIHS. The X5 has not been fully tested, yet.
