Hydroplaning

Depending on the depth of the water layer on
the road, hydroplaning may occur, even at low
speeds and with new tires. In heavy rain or
when conditions indicate possible
hydroplaning:
X

Avoid track grooves in the road.

Apply brakes cautiously.
Standing water
! Do not drive through flooded areas.
Before driving through water, determine its
depth.
If you must drive through standing water,
drive slowly to prevent water from entering
the passenger compartment or the engine
compartment. Water in these areas could
cause damage to electrical components or
wiring of the engine or transmission, or
could result in water being ingested by the
engine through the air intake causing
severe internal engine damage. Any such
damage is not covered by the Mercedes-
Benz Limited Warranty.
Prevent water from entering the passenger
compartment or the engine compartment. If
you must drive through standing water, keep
in mind that
