NOTICE
If driving through water, such
as when crossing shallowstreams, first check the depth of the water and the bottom of
the river bed for firmness. Driveslowly and avoid deep water.
Take all necessary safety mea-
sures to ensure that water dam-age to the engine or other com- ponents does not occur.
Water entering the engine airintake will cause severe engine
damage.
Water can wash the grease fromwheel bearings, causing rustingand premature failure, and mayalso enter the differentials,
transmission and transfer case,reducing the gear oil's lubrica-ting qualities.
Sand and mud that has accum-
lated in brake drums andaround brake discs may affectbraking efficiency and may dam-
age brake system components.
Always perform a maintenanceinspection after each day of
off- road driving that has takenyou through rough terrain,sand, mud, or water. For sche-
duled maintenance information,refer to the separate ºOwner's Manual Supplement/Maintenance
Scheduleº.
Winter driving tips
Make sure you have ethylene- glycol
antifreeze in the radiator.
NOTICE
Do not use alcohol type anti-freeze.
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 starting. 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
viscosity. 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 dealerÐhe 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.

Maintenance requirements
General maintenance

Does your vehicle need
repairing?
For scheduled maintenance in-
formation, please refer to the
separate ºOwner 's Manual Sup-
plement/Maintenance Scheduleº. Maintenance requirements
Your Toyota vehicle has been de-
signed to for fewer maintenance re-
quirements with longer service inter-
vals to save both your time and
money. However, each regular mainte-
nance, as well as day- to- day care, is
more important than ever before to
ensure smooth, and trouble- free, safe,
and economical drivings.
It is the owner 's responsib
ility to
make sure the specified maintenance,
including general maintenance service,
is performed. Note that both the new
vehicle and emission control system
warranties specify that proper mainte-
nance and care must be performed.
See ºOwner 's Guideº, ºOwner 's Manu-
al Supplementº or ºWarranty Bookletº
for complete warranty information.
General maintenance
General maintenance items are those
day- to- day care practices that are im-
portant to your vehicle for proper op-
eration. It is the owner 's responsib ility
to ensure that the general mainte-
nance items are performed regularly.
These checks or inspections can be
done either by yourself or a qualified
technician, or if you prefer, your Toyo-
ta dealer will be pleased to do them
at a nominal cost. Scheduled maintenance
The scheduled maintenance items
listed in the ºOwner 's Manual Supple-
ment/Maintenance Scheduleº are those
required to be serviced at regular in-
tervals.
For details of your maintenance
schedule, read the separate ºOwner 's
Manual Supplement/Maintenance
Scheduleº.
It is recommended that any replace-
ment parts used for maintenance or
for the repair of the emission con-
trol system be Toyota supplied.
The owner may elect to use non-
Toyota supplied parts for replace-
ment purposes without invalidating
the emission control system warran-
ty. However, use of replacement
parts which are not of equivalent
quality may impair the effectiveness
of the emission control systems.
You may also elect to have mainte-
nance, replacement, or repair of the
emission control devices and sys-
tem performed by any automotive
repair establishment or individual
without invalidating this warranty.
See ºOwner 's Guideº, ºOwner 's
Manual Supplementº or ºWarranty
Bookletº for complete warranty in-
formation.
