Driving Aids

SystemOperation When you connect a trailer to your vehicle, the trailer set up menu appears in the information display. This menu allows you to set up a new trailer or choose from a previously set up trailer. A warning message appears and the systemturns off if you do not choose or add a new trailer. Note: The warning message may not appear until your vehicle speed reaches 22 mph (35 km/h). If you select a trailer in the information display before connecting a trailer to your vehicle, the system loads the configuration for the selected trailer. When a trailer is connected, a warning message appears. Note: A second warning message may appear stating that the Cross Traffic Alert system has turned off. The Blind Spot Information System with Trailer Tow continues to function normally in this situation. Note: The system remembers the last selected trailer set up when you start your vehicle. Trailer Considerations The system is designed to work with a trailer with a front width of 8.5 ft (2.6 m) or less, and a total length from the trailer hitch ball to the rear of the trailer of 33 ft (10.1 m) or less. Some trailers may cause a slight change in system performance: • Large box trailers may cause false alerts to occur when driving next to infrastructures or near parked cars. A false alertmay also occur whilemaking a 90-degree turn. • Trailers that have a width greater than 8.5 ft (2.6 m) at the front and have a total length greater than 20 ft (6 m) may cause delayed alerts when a vehicle is passing at high speed.

• Box trailers that have a width greater than 8.5 ft (2.6 m) at the front may cause early alerts when you pass a vehicle. • Clam shell or V-Nose box trailers with a width greater than 8.5 ft (2.6 m) at the front may cause delayed alerts when a vehicle traveling the same speed as your vehicle merges lanes. SystemErrors If the system detects a fault, a warning lamp illuminates and a message displays. See InformationMessages (page 119). Switching the SystemOn and Off You can switch the system off using the information display. See General Information (page 109). Whenyou switch the systemoff, awarning lamp illuminates and a message displays. When you switch the system on or off, the alert indicators flash twice. Note: The system remembers the last setting when you start your vehicle. Note: The systemmay not correctly operate when towing a trailer. For vehicles with a trailer tow module and tow bar approved by us, the system turns off when you attach a trailer. For vehicles with an aftermarket trailer tow module or tow bar, we recommend that you switch the system off when you attach a trailer. To permanently switch the system off, contact an authorized dealer.
