1. Check the area around the vehicle be-
fore entering it.
2. Adjust seat position, seatback angle, seat cushion angle, head restraint
height and steering wheel angle.
3. Adjust the inside and outside rear view mirrors.
4. Lock all doors.
5. Fasten seat belts. Once you turn the ignition key to “START”
position and release it, the cranking hold
function continues to crank the engine in
“ON” position until it starts.
The function stops cranking the engine
after about 25 seconds maximum if the
engine has not started yet. When you
crank the engine again, wait a few sec-
onds and restart it.
If you hold the key in “START” position,
the function will keep cranking for about
30 seconds maximum. 1. Apply the parking brake firmly.
2. Turn off unnecessary lights and acces-
sories.
3. Manual transmission: Press the clutch
pedal to the floor and shift the trans-
mission into neutral. Hold the clutch
pedal to the floor until the engine is
started. A starter safety device will pre-
vent the starter from operating if the
clutch pedal is not fully depressed.
Automatic transmission: Put the se-
lector lever in “P”. If you need to re-
start the engine while the vehicle is
moving, put the selector lever in “N”.
A starter safety device will prevent the
starter from operating if the selector
lever is in any drive position.
4. Automatic transmission only:
De-
press the brake pedal and hold it to
the floor until driving off.

Before starting the engine, be sure to fol-
low the instructions in “(a) Before crank-
ing”.
Normal starting procedure
The multiport fuel injection system/sequen-
tial multiport fuel injection system in your
engine automatically controls the proper
air−fuel mixture for starting. You can start
a cold or hot engine as follows:
5VZ− FE engine—With your foot off the ac-
celerator pedal, crank the engine by turn-
ing the ignition key to “START” position.
Release it when the engine starts.
2UZ− FE engine—With your foot off the
accelerator pedal, turn the ignition key to
“START” position, then release it.
Engine should be warmed up by driving,
not in idle. For warming up, drive with
smoothly turning engine until engine cool-
ant temperature is within normal range.
If the engine stalls...
Simply restart it, using the correct proce-
dure given in normal starting.
If the engine will not start...
See “If your vehicle will not start” in Sec-
tion 4.NOTICE
 5VZFE engine only—Do not crank
for more than 30 seconds at a time.
This may overheat the starter and
wiring systems.
 Do not race a cold engine.
 If the engine becomes difficult to
start or stalls frequently, have the
engine checked immediately.
Always slow down in gusty crosswinds.
This will allow you much better control.
Drive slowly onto curbs and, if pos-
sible, at a right angle. Avoid driving
onto high, sharp− edged objects and
other road hazards. Failure to do so
can lead to severe tire damage such
as a tire burst.
Drive slowly when passing over bumps
or travelling on a bumpy road. Other-
wise, the impact could cause severe
damage to the tires and/or wheels.
When parking on a hill, turn the front
wheels until they touch the curb so
that the vehicle will not roll. Apply the
parking brake, and place the transmis-
sion in “P” (automatic) or in first or
reverse (manual). If necessary, block
the wheels.

Washing your vehicle or driving through
deep water may get the brakes wet. To
see whether they are wet, check that
there is no traffic near you, and then
press the pedal lightly. If you do not
feel a normal braking force, the brakes
are probably wet. To dry them, drive
the vehicle cautiously while lightly
pressing the brake pedal with the park-
ing brake applied. If they still do not
work safely, pull to the side of the road
and call a Toyota dealer for assistance.
Four−wheel drive models only—Toyota
recommends not using four −wheel drive
on dry hard −surfaced roads, because
four −wheel driving will cause unneces-
sary noise and wear, and poor fuel
economy.
Four −wheel drive models only—In cold
temperatures, noise may occur when
driving in two −wheel drive before the
transfer is warmed up. Therefore, first
drive in four −wheel drive until the
transfer is warmed up.
CAUTION
Before driving off, make sure that
the parking brake is fully released
and the parking brake reminder
light is off.
Do not leave your vehicle unat-
tended while the engine is running.
Do not rest your foot on the brake
pedal while driving. It can cause
dangerous overheating, needless
wear, and poor fuel economy.
To drive down a long or steep hill,
reduce your speed and downshift.
Remember, if you ride the brakes
excessively, they may overheat and
not work properly.
Be careful when accelerating, up-
shifting, downshifting or braking on
a slippery surface. Sudden accelera-
tion or engine braking could cause
the vehicle to spin or skid.
Do not drive in excess of the speed
limit. Even if the legal speed limit
permits it, do not drive over 140
km/h (85 mph) unless your vehicle
has highspeed capability tires.
Driving over 140 km/h (85 mph) may
result in tire failure, loss of control
and possible injury. Be sure to con-
sult a tire dealer to determine
whether the tires on your vehicle
are highspeed capability tires or
not before driving at such speeds.
Do not continue normal driving
when the brakes are wet. If they are
wet, your vehicle will require a
longer stopping distance, and it
may pull to one side when the
brakes are applied. Also, the park-
ing brake will not hold the vehicle
securely.

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 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.
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.
Winter driving tips

’04 TUNDRA_U (L/O 0309)

2004 TUNDRA from Sep. ’03 Prod. (OM34426U)
Make sure the engine oil viscosity is
suitable for the cold weather.
See Section 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 deal-
er—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.
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” (automatic) or into first or reverse
(manual) 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.
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

2004 TUNDRA from Sep. ’03 Prod. (OM34426U)
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.
We recommend you use a weight distribut-
ing hitch when towing to keep your ve-
hicle level with the ground.
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.
WEIGHT LIMITS
Before towing, make sure the total trail-
er weight, gross combination weight,
gross vehicle weight, gross axle weight
and trailer tongue load are all within
the limits.
The total trailer weight and tongue load
can be measured with platform scales
found at highway weighing stations, build-
ing supply companies, trucking companies,
junk yards, etc.
CAUTION
The maximum gross trailer weight
(trailer weight plus cargo weight)
must never exceed the following.

If towing a trailer and cargo weigh-
ing over 907 kg (2000 lb.), it is
necessary to use a sway control
device with sufficient capacity. The
combination of the gross trailer
weight added to the total weight of
the vehicle, occupants and vehicle
cargo must never exceed a total of
the following.
5VZFE engine
Twowheel drive models 4173 kg (9200 lb.)
Fourwheel drive models
4309 kg (9500 lb.)
2UZFE engine Without towing package 4536 kg (10000 lb.)
With towing package
5352 kg (11800 lb.)
Exceeding the maximum weight of
the trailer, the vehicle, or the ve-
hicle and trailer combination, can
cause an accident resulting in seri-
ous personal injuries.
Trailer hitch assemblies have differ-
ent weight capacities established by
the hitch manufacturer. Even though
the vehicle may be physically capa-
ble of towing a higher weight, the
operator must determine the maxi-
mum weight rating of the particular
hitch assembly and never exceed
the maximum weight rating speci-
fied for the trailerhitch. Exceeding
the maximum weight rating set by
the trailer hitch manufacturer can
cause an accident resulting in seri-
ous personal injuries.
The gross vehicle weight must not
exceed the Gross Vehicle Weight
Rating (GVWR) indicated on the
Certification Label. The gross ve-
hicle weight is the sum of weights
of the unloaded vehicle, driver, pas-
sengers, luggage, hitch and trailer
tongue load. It also includes the
weight of any special equipment
installed on your vehicle.
The load on either the front or rear
axle resulting from distribution of
the gross vehicle weight on both
axles must not exceed the Gross
Axle Weight Rating (GAWR) listed
on the Certification Label.
