Winter Driving Tips - Toyota TUNDRA 2004 Owner's Manual

NOTICE
z 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.
z 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 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.
z Sand and mud that has accumulated
in brake drums and around brake
discs may affect braking efficiency
and may damage brake system com-
ponents.

z 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
formation, refer to the "Scheduled
Maintenance Guide" or "Owner's
Manual Supplement".

Winter driving tips

Make sure your coolant is properly pro-
tected against freezing.
Only use "Toyota Super Long Life Coolant"
or similar high quality ethylene glycol
based non−silicate, non−amine, non−nitrite,
in-
and non−borate coolant with long−life hy-
brid organic acid technology.
See "Checking the engine coolant level" in
Section 7−2 for details of coolant type
selection.
"Toyota Super Long Life Coolant" is pre−
mixed with 50% coolant and 50% deion-
ized water. This coolant provides protec-
tion down to about −35_C (−31_F).
NOTICE
Do not use plain water alone.
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. Section 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.
