NOTICE
■To prevent water damage
Take  all  necessary  safety  measures  to  ensure  that  water  damage  to  the
engine or other components does not occur.
● Water entering the engine air intake will cause severe engine d amage. 
● Water  entering  the  automatic transmission will cause  deteriorat ion in  shift
quality, locking up of your transmission accompanied by vibrati on, and ulti-
mately damage.
● Water can wash the grease from wheel bearings, causing rusting  and pre-
mature  failure,  and  may  also  enter  the  differentials,  transmission  and
transfer 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  firmn ess.  Drive
slowly and avoid deep water.
■ Inspection after off-road driving
● Sand  and  mud  that  has  accumulated  in  brake  drums  and  around  bra ke
discs may affect braking efficiency and may damage brake system  compo-
nents.
● Always  perform  a  maintenance  inspection  after  each  day  of  off-r oad  driv-
ing  that  has  taken  you  through  rough  terrain,  sand,  mud,  or  wat er.  For
scheduled maintenance information, refer to the “Scheduled Main tenance
Guide” or “Owner’s Manual Supplement”.
