The Cadillac Escalade IQ has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps 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 Hummer EV SUV doesn’t offer knee airbags.

The Escalade IQ has standard head airbag curtains for all three seat rows which act as a forgiving barrier between the driver and outboard passenger's upper bodies and the window and pillars.
