NOTICE
■ To prevent water damage
Take all necessary safety mea-
sures to ensure that water dam-
age to the hybrid battery (traction
battery), hybrid system or other
components does not occur.
● Water entering the engine com-
partment may cause severe
damage to the hybrid system.
Water entering the interior may
cause the hybrid battery (trac-
tion battery) stowed under the
rear seats to short circuit.
● Water entering the hybrid trans-
mission will cause deterioration
in transmission quality. The mal-
function indicator may come on,
and the vehicle may not be driv-
able.
● Water can wash the grease
from wheel bearings, causing
rusting and premature failure,
and may also enter the hybrid
transmission case, reducing the
gear oil's lubricating qualities.
■ When you drive through
water
If driving through water, such as
when crossing shallow streams,
first check the depth of the water
and the bottom of the riverbed for
firmness. Drive slowly and avoid
deep water.
■ Inspection after off-road driv-
ing
● Sand and mud that has accu-
mulated in brake drums and
around brake discs may affect
braking efficiency and may
damage brake system compo-
nents.

● Always perform a maintenance
inspection after each day of
off-road driving that has taken
you through rough terrain, sand,
mud, or water. For scheduled
maintenance information, refer
to the "Scheduled Maintenance
Guide" or "Owner's Manual
Supplement".
