Driving on wet roads
Hydroplaning If water has accumulated to a certain depth
on the road surface, there is a danger of
hydroplaning occurring, eve
nif:
R you drive at low speeds.
R the tires have adequate tread depth.
For this reason, in the event of heavy rain or
in conditions in which hydroplaning may
occur, you must drive in the following
manner:
R lower you rspeed.
R avoid ruts.
R brake carefully.
Driving on flooded roads !
Do not drive through flooded areas.
Check the depth of any water before driving
through it. Drive slowly through standing
water. Otherwise, water may enter the
vehicle interior or the engine compartment.
This can damage the electronic
components in the engin eorthe automatic
transmission. Water can also be drawn in
by the engine's air suction nozzles and this
can cause engine damage.
Prevent water from entering the vehicle
interior or the engine compartment. If you
must drive through standing water, bear in
mind that:
R the maximum permissible depth in still
water is 12 in (30 cm)
R you should drive no faster than at walking
pace Winter driving
