Driving on wet roads

Hydroplaning

If water has accumulated to a certain depth on the road surface, there is a danger of hydroplaning occurring, even if:

 - you drive at low speeds.
 - the tires have adequate tread depth.

For this reason, in the event of heavy rain or in conditions in which hydroplaning can occur you must drive in the following manner:

 - reduce your speed
 - avoid ruts
 - 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 engine or the automatic transmission. Water can also be drawn in by the engine's air suction nozzles and this can cause engine damage.
