Other information:
Reverse Automatic Braking (RAB) is a
system designed to help avoid collisions or
reduce collision damage when reversing
the vehicle. If a wall or an obstacle is
detected in the reversing direction, the
system will notify the driver with a warning
sound and may activate the vehicle’s
brakes automatically...
To help prevent moisture from forming in
the fuel system and the risk of its freezing,
use of an antifreeze additive in the fuel
tank is recommended during cold weather.
Use only additives that are specifically
designed for this purpose. When an antifreeze
additive is used, its effect lasts
longer if the tank is refilled whenever the
fuel level reaches half empty...
