Notes on driving through water on the road
Water ingress can damage the engine, electrics
and transmission.
Water can also enter the air intake of the engine
and cause engine damage.
Observe the following notes if you have to drive
through water:
The water, when calm, may reach no higher
R
than the lower edge of the vehicle body.
Drive at walking pace at most; water may oth-
R
erwise enter the vehicle interior or engine
compartment.
Vehicles in front or oncoming vehicles can
R
create waves that may exceed the maximum
permissible depth of water.
The braking effect of the brakes is reduced after
you have driven through water. Brake carefully,
paying attention to the traffic conditions, until
braking effect has been fully restored.
Function of rear axle steering
The rear axle steering is an electromechanical
auxiliary steering on the rear axle which adjusts
the steering of the rear wheels according to the
position of the front wheels, depending on the
speed. This results in greater maneuverability and
improved driving stability for the vehicle.
Rear axle steering has the following characteris-
tics:
reduced steering effort and turning circle
R
resulting in reduced parking effort
more direct steering resulting in improved
R
control of the vehicle
improved cornering of the vehicle
