Winter Driving Tips - Toyota tundra 2003 User 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.
Your coolant must contain ethylene−glycol
type coolant for a proper
protection of aluminum components. Use
in-
"Toyota Genuine Long Life Coolant" or
equivalent.
See Section 7−2 for details about coolant
type selection.
NOTICE
Do not use alcohol type antifreeze or
plain water alone.
When it is extremely cold, we recommend
to use 60% solution for your Toyota, to
provide protection down to about −50_C
(−58_F). Do not use more than 70% solu-
tion for better coolant performance.
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.
