cle.

■ When encountering flooded roads
Do not drive on a road that has flooded after heavy rain, etc. Doing so may
cause the following serious damage to the vehicle:
● Engine stalling
● Short in electrical components
● Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle i s flooded, be
sure to have your Toyota dealer check the following:
● Brake function
● Changes in quantity and quality of oil and fluid used for the engine, trans-
mission, transfer (4WD models) differentials, etc.
● Lubricant condition for the propeller shaft, bearings and suspe nsion joints
(where possible), and the function of all joints, bearings, etc .

3304-6. Driving tips
NOTICE
■To prevent the 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 river bed for firm ness. 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”.
