”N” (neutral position):
Lever at ”N”
No power is delivered to the wheels. The
vehicle must be stopped.
”L4” (low speed position, four-wheel
drive): Lever at ”L4”
Use this for maximum power and traction.
Use ”L4” for climbing or descending steep
hills, off-road driving, and hard pulling in
sand, mud or deep snow.
See ”(c) Shifting procedure” for further
instructions.
The A.D.D. can be engaged or disen-
gaged by the shifting operations de-
scribed in ”(c) Shifting procedure”.
You should drive in four-wheel drive for at
least 16 km (10 miles) each month. This
will assure that the front drive components
are lubricated.
(b) A.D.D. (automatic
disconnecting differential)

NOTICE
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
firmness. Drive slowly and avoid
deep water.
Take all necessary safety measures
to ensure that
damage to the engine or other com-
ponents does not occur.
Water entering the engine air intake
will cause severe engine damage.
Water can wash the grease from
wheel bearings, causing rusting and
premature failure, and may also en-
ter the differentials, transmission
and transfer case, reducing the gear
oil’s lubricating qualities.
Sand and mud that has accumulated
in brake drums and around brake
discs may affect braking efficiency
and may damage brake system com-
ponents.
Always perform a maintenance in-
spection after each day of off-road
driving that has taken you through
rough terrain, sand, mud, or water.
For scheduled maintenance informa-
tion, refer to the separate ”Owner’s
Manual Supplement/Maintenance
Schedule”.
Winter driving tips
Make sure you have ethylene-glycol an-
tifreeze in the radiator.
NOTICE
Do not use alcohol type antifreeze.
Check the condition of the battery and
cables.
Cold temperatures reduce the capacity of
any battery, so it must be in top shape
to provide enough power for winter start-
ing. Chapter 7 −3 tells you how to visually
inspect the battery. Your Toyota dealer
and most service stations will be pleased
to check the level of charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See Chapter 7 −2 for recommended viscos-
ity. Leaving a heavy summer oil in your
vehicle during winter months may cause
harder starting. If you are not sure about
which oil to use, call your Toyota dealer–
he will be pleased to help.
Keep the door locks from freezing.
Squirt lock de-icer or glycerine into the
locks to keep them from freezing. To open
a frozen lock, try heating the key before
inserting it.
