RollTek Rollover Protection System
Warning: Always use the seat belts when operating the vehicle. Failure to do so can result in severe personal injury or death. Do not place infants and children in seats equipped with the RollTek system. The RollTek system is designed for adults only. Doing so could result in severe bodily injury or death. Keep all heavy objects in the cab secured. Do not place objects on the seat back or block the side-roll air bag. Objects that block the side-roll air bag may prevent proper inflation and could result in serious injury or death.
Important: The RollTek system must be replaced after being activated. Damaged seat belts and tethers, or seat belts and tethers that were worn in an accident, must be replaced, and their anchoring points must be checked.
The RollTek system, when used with seat belts, provides additional protection to the driver and passenger (if equipped with a passenger-side system) in rollover accidents. See Fig..
Fig. 1, Rolltek Seat
The RollTek system provides a significant increase in seat stability during a rollover. Vehicles equipped with RollTek rollover protection have a sensor mounted in the seat base that activates the side-roll air bag and seat pull-down device during a rollover. When the RollTek module senses a rollover, the module triggers gas cylinders mounted in the base of the seat. The gas cylinders activate the power cinches that then tighten the lap and shoulder belts against the occupant of the seat and lower the seat suspension, moving the occupant down and away from the steering wheel and ceiling. The side-roll air bag deploys from the outboard side of the seat as the seat is pulled down to its lowest position.
The operational readiness of the RollTek system is indicated by the supplemental restraint system (SRS) indicator on the dash. The SRS indicator illuminates for several seconds when the ignition is turned on, and then it goes off. The indicator remains on if there is a problem with the air bag or RollTek system. The vehicle must be serviced if the SRS indicator does not illuminate when the ignition is turned on, or if the SRS indicator remains on.
Warning: Keep hands and tools away from the scissor points under the seats. The RollTek system contains components that use combustible chemicals. Do not cut, drill, braze, solder, weld, strike, or probe any part of the RollTek system. Keep all liquids and chemicals away from the RollTek components. Do not attempt to service or modify the RollTek system. Unintentional or improper deployment of the RollTek system could cause severe bodily injury or death.
