SERVICE TRAILER BRAKE SYSTEM On vehicles with the Integrated Trailer Brake Control (ITBC) system, this message displays and a chime sounds when there is a problem with the ITBC system. When this message displays, power is no longer available to the trailer brakes. As soon as it is safe to do so, carefully pull your vehicle over to the side of the road and turn the ignition off. Check the wiring connection to the trailer and turn the ignition back on. If this message still displays, either your vehicle or the trailer needs service. See your dealer/retailer. See "Integrated Trailer Brake Control System" under Towing a Trailer on page 4-50 for more information. SIDE BLIND ZONE SYS. (System) UNAVAILABLE If your vehicle has the Side Blind Zone Alert (SBZA) system, this message displays when the SBZA system is disabled because the sensor is blocked and cannot detect vehicles in your blind zone. The sensor may be blocked by mud, dirt, snow, ice, or slush. This message may also display during heavy rain or due to road spray. It may also come on when driving in isolated areas with no guardrails, trees, or road signs and light traffic. Your vehicle does not need service. For cleaning instructions, see Washing Your Vehicle on page 5-110. See Side Blind Zone Alert (SBZA) on page 2-58 for more information. SIDE BLIND ZONE ALERT SYSTEM OFF If your vehicle has the Side Blind Zone Alert (SBZA) system, this message displays when the SBZA system has been turned off. See Side Blind Zone Alert (SBZA) on page 2-58 and DIC Operation and Displays (With DIC Buttons) on page 3-52 or DIC Operation and Displays (Without DIC Buttons) on page 3-58 for more information. STABILITRAK OFF If your vehicle has StabiliTrak, this message displays when you turn off StabiliTrak, or when the stability control has been automatically disabled. To limit wheel spin and realize the full benefits of the stability enhancement system, you should normally leave StabiliTrak on. However, you should turn StabiliTrak off if your vehicle gets stuck in sand, mud, ice, or snow and you want to rock your vehicle to attempt to free it, or if you are driving in extreme off-road conditions and require more wheel spin. See If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on page 4-31. To turn the StabiliTrak system on or off, see StabiliTrak® System on page 4-6. 3-71
