2008 TOYOTA TUNDRA Owners Manual

2008 TUNDRA from Apr. ’08 Prod. (OM 34477U)
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 water damage to the
engine or other components does
not occur.
 Water entering the engine air intake
will cause severe engine damage.
 Water entering the automatic trans-
mission will cause deterioration in
shift quality, locking up of your
transmission accompanied by vibra-
tion, and ultimately 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 offroad
driving that has taken you through
rough terrain, sand, mud, or water.
For scheduled maintenance in-
formation, refer to the “Scheduled
Maintenance Guide” or “Owner’s
Manual Supplement”.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,
and non −borate coolant with long −life hy-
brid organic acid technology. (Coolant with
long −life hybrid organic acid technology is
a combination of low phosphates and or-
ganic acids.)
See “Checking the engine coolant level”
on page 551 in Section 7 −2 for details of
coolant type selection.
For the U.S.A.—“Toyota Super Long Life
Coolant” is a mixture of 50% coolant and
50% deionized water. This coolant pro-
vides protection down to about −35 C
( − 31 F).
For Canada—“Toyota Super Long Life
Coolant” is a mixture of 55% coolant and
45% deionized water. This coolant pro-
vides protection down to about −42 C
( − 44 F).
NOTICE
Do not use plain water alone.
Winter driving tips

2008 TUNDRA from Apr. ’08 Prod. (OM 34477U)
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.
Make sure the engine oil viscosity is
suitable for the cold weather.
See page 549 in Section 7 −2 for recom-
mended viscosity. Leaving a heavy sum-
mer 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—they 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.
Use a washer fluid containing an anti
freeze solution.
This product is available at your Toyota
dealer and most auto parts stores. Follow
the manufacturer ’s directions for how
much to mix with water.NOTICE
Do not use engine antifreeze or any
other substitute because it may dam-
age your vehicle’s paint.
Do not use your parking brake when
there is a possibility it could freeze.
When parking, put the transmission into
“P” and block the front wheels. Do not
use the parking brake, or snow or water
accumulated in and around the parking
brake mechanism may freeze, making it
hard to release.
Keep ice and snow from accumulating
under the fenders.
Ice and snow built up under your fenders
can make steering difficult. During bad
winter driving, stop and check under the
fenders occasionally.
Depending on where you are driving,
we recommend you carry some emer-
gency equipment.
Some of the things you might put in the
vehicle are tire chains, window scraper,
bag of sand or salt, flares, small shovel,
jumper cables, etc.XS30007
Your vehicle is not designed to be
dinghy towed (with four wheels on the
ground) behind a motorhome.
NOTICE
Do not tow your vehicle with four
wheels on the ground. This may
cause serious damage to your vehicle.
Dinghy towing

481
2008 TUNDRA from Apr. ’08 Prod. (OM 34477U)
Your vehicle is designed primarily as a
passenger−and− load− carrying vehicle. Tow-
ing a trailer will have an adverse effect on
handling, performance, braking, durability
and driving economy (fuel consumption,
etc.). Your safety and satisfaction depend
on the proper use of correct equipment
and cautious driving habits. For your safe-
ty and the safety of others, you must not
overload your vehicle or trailer. Ask your
local Toyota dealer for further details be-
fore towing.
NOTICE
When towing a trailer, be sure to con-
sult your Toyota dealer for further in-
formation on additional requirements
such as a towing kit, etc.
CAUTION
To tow a trailer safely, use extreme
care and drive the vehicle in accor-
dance with the trailer ’s characteristics
and operating conditions.
The vehicle stability and braking per-
formance are affected by trailer sta-
bility, brake setting and performance,
and the hitch.
Follow all the instructions described
in this section. Failure to do so could
cause an accident resulting in death
or serious injury.
WEIGHT LIMITS
Before towing, make sure the gross
trailer weight, gross combination
weight, gross vehicle weight, gross axle
weight and trailer tongue load are all
within the limits.
The gross trailer weight and tongue load
can be measured with platform scales
found at a highway weighing station, build-
ing supply company, trucking company,
junk yard, etc.

2008 TUNDRA from Apr. ’08 Prod. (OM 34477U)
Reference
Vehicle weight
The tongue load is the load placed on the trailer hitch ball.
The king pin weight is the load placed on the fifth wheel trailer hitch mount.
GVWR (Gross Vehicle Weight Rating)
is the maximum allowable gross vehicle weight.
The gross vehicle weight is the total weight of the vehicle. When towing a trailer, it is the sum of the vehicle weight
(including the occupants, cargo and any optional equipment installed on the vehicle) and the tongue load (or the king pin
weight).
GAWR (Gross Axle Weight Rating) is the maximum allowable gross axle weight.
The gross axle weight is the load placed on each axle (front and rear).
GCWR (Gross Combination Weight Rating) is the maximum allowable gross combination weight.
The gross combination weight is the sum of the total vehicle weight (including the occupants, cargo and any optional
equipment installed on the vehicle) and the weight of the trailer being towed (including the cargo in the trailer).
The gross trailer weight is the sum of the trailer weight and the weight of the cargo in the trailer.
Towing Capacity is the maximum allowable gross trailer weight.
Towing Capacity is calculated considering base vehicle with necessary vehicle equipment and 150 pound driver.
Additional optional equipment, passengers and cargo in the vehi cle will reduce the towing capacity, Gross Trailer weight
includes the trailer, cargo and necessary equipment for towing.
