Wa ter which has entered into theve hicle can
damage the engine, electrics and transmission.
Wa ter can also enter the air intake of the engine
and cause engine damage.
Obser vethefo llowing if you must drive thro ugh
wa ter:
R The water,when calm, may only reach the
lo we r edge of theve hicle body.
R Drive at a maximum speed of 10 km/h; water
can otherwise enter theve hicle interior or
engine compartment.
R Vehicles tr avelling in front, or oncoming vehi-
cles, can create waves which may exceed the
maximum permissible dep thofthewa ter.
