4–178

When Driving

i-ACTIVSENSE

NOTE

Under the following conditions, the radar sensor (front) may not be able to detect

vehicles ahead or obstructions correctly and each system may not operate normally.

The rear surface of a vehicle ahead does not re

À ect radio waves effectively, such as

an unloaded trailer or an automobile with a loading platform covered by a soft top,
vehicles with a hard plastic tailgate, and round-shaped vehicles.

Vehicles ahead with low vehicle height and thus less area for re

À ecting radio waves.

Visibility is reduced due to a vehicle ahead casting off water, snow, or sand from its

tyres and onto your windscreen.

The boot/luggage compartment is loaded with heavy objects or the rear passenger

seats are occupied.

Ice, snow, or soiling is on the front surface of the front emblem.

During inclement weather such as rain, snow, or sand storms.

When driving near facilities or objects emitting strong radio waves.

Under the following conditions, the radar sensor (front) may not be able to detect

vehicles ahead or obstructions.
