DRIVING THROUGH WATER
Do not drive quickly through
standing water, especially if the
depth is unknown. Traction or
brake capability may be limited and
if the ignition system gets wet, your
engine may stall. Water may also
enter your engine's air intake and
severely damage your engine.
If driving through deep or standing
water is unavoidable, proceed very
slowly. Never drive through water
that is higher than the bottom of
the hubs.
Once through the water, always try
the brakes. Wet brakes do not stop
the vehicle as effectively as dry
brakes. Drying can be improved by
moving your vehicle slowly while
applying light pressure on the brake
pedal.
Driving through deep water
where the transaxle is
submerged may allow water
into the transaxle and cause
internal transaxle damage.
