04 Comfort and driving pleasure Collision warning with Auto-brake* NOTE tions, the ABS and DSTC systems provide the best possible braking effect while helping to maintain stability. WARNING • When Adaptive Cruise Control is used, the warning light and signal will be used by that function, even if the warnings provided by Collision Warning have been deactivated by the driver. In situations where traffic is moving at considerably different speeds, or if the vehicle ahead brakes suddenly, warnings may be considered to be late, even if the setting Long has been selected. • NOTE The visual warning signal may be temporarily disengaged in the event of high passenger compartment temperature due to strong sunlight, etc. If this occurs, the audible warning signal will be used, even if it has been deactivated in the menu system. • In certain situations, the system cannot provide warnings or warnings may be delayed if traffic conditions or other external factors make it impossible for the radar sensor or camera to detect a vehicle ahead. Warnings may not be provided if the distance to the vehicle ahead is short, or if movements of the steering wheel/ brake pedal are great, such as during active driving. The sensor system has a limited range for stationary or slow-moving vehicles and may therefore give delayed or no warnings if your vehicle's speed is above approximately 45 mph (70 km/h). Warnings for stationary or slow-moving vehicles may not be provided in dark conditions. • 04 Checking settings The current Collision Warning settings can be checked by going into the menu system at Car settings Collision warning settings. See page 122 for more information on the menu system. • • Limitations Strong sunlight, reflections, extreme light contrasts, the use of sunglasses, or if the driver is not looking straight ahead may make the visual warning signal in the windshield difficult to see. For this reason, always activate the audible warning signal. Slippery driving conditions increase braking distance, which can reduce the system's capacity to avoid a collision. In these condi- The Collision Warning system uses the same radar sensors as Adaptive Cruise Control. For more information on the radar sensor and its limitations, see page 165. If no warning is given, or if a warning is delayed, Auto-brake will also not be provided or will be delayed. `` * Option/accessory, for more information, see Introduction. 175
