Wet Conditions
When driving in wet conditions, water can build up under your
tires so that they ride on a layer of water. This is called
aquaplaning or hydroplaning. When this happens, you have little
or no control. Aquaplaning is more prone to happening at higher
road speeds if there is a lot of water on the road and particularly
if the tires are also under inflated or approaching minimum tread
depth.
It is important to take bends or curves at a safe, reasonable speed,
particularly when driving on wet or slippery road surfaces.
Slow down when it is raining.
Driving Through Deep Water
If in any doubt whether to drive through deep water, always take
the side of caution to avoid potentially costly damage to the
vehicle's engine or other essential systems.
Caution: Never drive in water deeper than the lower edge
of the front bumper. Water can be splashed up into the
engine air intakes located in the front upper grille and cause
extensive damage to the engine or the vehicle may stall.
Always proceed with extreme caution, especially when the
depth is not known.
When driving through water, traction or brake capability may be
limited. Once through the water, always dry the brakes by driving
slowly while applying light pressure on the brake pedal.
Waves caused by other vehicles or natural causes can also
splash water in the engine air intakes.
Tire Skip At Low Speed
In certain conditions, the front tires may 'skip' at low speeds with
summer tires installed when a high level of steering lock is
applied. This is a characteristic of the vehicle and does not affect
the safety or performance of the vehicle.
