● The recommended speed modes for the listed terrains ( P. 254) are only
a reference. The selected mode may not be suitable to actual of f-road con-
ditions due to factors such as the type or unevenness of the te rrain or the
degree of incline. Check the actual terrain thoroughly and drive safely.

2804-6. Driving tips
4RUNNER (U)
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”.
