Normally, the license plate and taillight reflectors give the rear section of a vehicle ahead sufficient reflective surfaces to be detected. Limitations WARNING The laser sensor emits light when the ignition is in mode II or higher, even if City Safety™ has been switched off. The sensor used by City Safety™ is designed to detect cars and other larger motor vehicles ahead of your vehicle in both daylight and darkness. However, there are certain limitations and the laser sensor's function may be reduced by, for example, heavy rain or snowfall, or by dense fog or thick, blowing dust or snow. Condensation, dirt, ice or snow on the windshield may also interfere with the sensor's function. Objects such as warning flags hanging from long objects on the roof or accessories such as auxiliary lights or protective arches on the front of the vehicle that are higher than the hood may also impede the sensor's function. Braking distance to the vehicle ahead increases on slippery road surfaces, which may reduce City Safety's capacity to avoid a collision. In situations like this, the DSTC system (see page 156) will help provide the best possible braking capacity and stability. City Safety™ emits infrared light and measures the way in which the light is reflected. Therefore, vehicles or objects with low-reflective sur- NOTE • • • Keep the windshield in front of the laser sensor free of ice, snow, dirt, etc. See page 168. Snow or ice on the hood deeper than 2 inches (5 cm) may obstruct the sensor. Keep the hood free of ice and snow. Do not mount or in any way attach anything on the windshield that could obstruct the laser sensor. 04 To switch City Safety™ on again: • Follow the same procedure as for switching City Safety™ off but select On by pressing RESET. or • Vehicles not equipped with keyless drive: Press lightly on the remote key to release it partially from the ignition slot. Press the remote key into the ignition slot again. Depress the brake pedal and press the START/STOP ENGINE button to start the engine. This restarts City Safety™. Troubleshooting If Windshield sensors blocked appears in the information display, this indicates that the City Safety™ laser sensor is obstructed in some way and cannot detect vehicles ahead of you, which means that the system is not functioning. However, this message will not be displayed in all situations in which the sensor is obstructed. For this reason, the driver must ensure that the area of the windshield in front of the sensor is always kept clean. • Vehicles equipped with the optional keyless drive: Press the START/STOP ENGINE button to switch off the engine. Depress the brake pedal and press the START/STOP ENGINE button to start the engine. This restarts City Safety™. See page 79 for information on ignition modes. `` 169
