Safety and security

As with all vehicles built on GM's new full-size SUV platform, the '07 Yukon family features a 360-degree safety system designed around the pillars of occupant protection, driver control and personal safety.

New features, including exclusive safety belt pretensioners linked to sensors for rear-end crashes, are integrated into a stronger vehicle structure that is also designed for improved compatibility with other vehicles - helping Yukon protect those inside and outside of the vehicle before, during and after a crash. The exclusive rear pretensioner sensors can trigger the front seat pretensioners during a rear-end collision, holding the occupants firmly in place and helping to prevent whiplash injuries

Also, new roof-mounted head curtain air bags with tethers are available for all seating rows (standard on Yukon Denali). The roof-mounted air bags' tether system keeps the bags in place longer to further protect and contain occupants. The bags stay inflated for several seconds longer to provide optimum protection in the case of a rollover or crash with secondary impacts. Sensors located at the front and rear of the vehicles, as well as the side doors provide increased and more immediate crash detection.

The myriad of crash sensors are complemented by increased roll-over detection from the standard StabiliTrak stability control system with new rollover mitigation technology. The electronically controlled system continuously measures the side angle of the vehicle and, if a rollover appears imminent, it can deploy the side-curtain air bags before the crash occurs. The 360 degrees of detection capability allows the electronically controlled safety systems to deploy in a greater variety of situations.

Crash avoidance is bolstered through enhanced driver control dynamics, driven by the standard StabiliTrak stability control system. It is supported by dynamics such as wider front and rear tracks, as well as more responsive suspensions. The vehicles' stronger and stiffer, fully-boxed frame is designed for improved crash energy management. The front frame section, for example, has improved crush dynamics that provides the equivalent of 17.7 inches (450 mm) of additional crush space - in vehicles that are only approximately 3 inches (76.2 mm) longer than their predecessors. The frame also is designed for improved vehicle-to-vehicle compatibility in the event of a frontal impact with a smaller vehicle.

Additional safety and security features include: + Standard dual-stage driver's front air bag + Standard dual-stage outboard-front passenger air bag with passenger occupant detection system + 5-star frontal impact ratings anticipated + Standard tire pressure monitoring system + Available rain-sensing wiper system + Available Ultrasonic Rear Parking Assist that can detect people or objects in the rearward path of the vehicle and send an audible warning sound + Available rear-view camera system that can visually detect people or object in the rearward path of the vehicle + Standard pull-up/push-down power window switches

All models come with the Generation 6 OnStar system (with a one-year Safe and Sound service plan), which provides the personal protection component of Yukon 's safety pillars. The system includes the General Motors Advanced Automatic Crash Notification (AACN) system, making crash data available to emergency services to potentially dispatch the appropriate life-saving personnel and equipment to crash scenes faster. If the vehicle is in a crash that activates an airbag, the OnStar system automatically notifies an OnStar Advisor who will check on the occupants or summon emergency help if necessary. OnStar also can assist authorities in locating a vehicle if it is reported stolen (ability to locate stolen vehicles varies with conditions).
