Fuel gauge
With tachometer
Without tachometer
The gauge works when the ignition
switch is on and indicates the approxi-
mate quantity of fuel remaining in the
tank.
Nearly fullNeedle at F"
Nearly emptyNeedle at E"
It is a good idea to keep the tank over
1/4 full.
This fuel gauge has a non−return type
needle which remains at the last indicated
position when the ignition switch is turned
off.
If the fuel level approaches E" or the low
fuel level warning light comes on, fill the
fuel tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the fuel gauge
needle may fluctuate or the low fuel level
warning light may come on earlier than
usual.
If the fuel tank is completely empty, the
malfunction indicator lamp comes on. Fill
the fuel tank immediately.
The indicator lamp goes off after driving
several times. If the indicator lamp does
not go off, contact your Toyota dealer as
soon as possible.

Engine coolant temperature
gauge

’01 Tacoma U (L/O 0009)
11 52001 TACOMA (OM35766U)
The gauge indicates the engine coolant
temperature when the ignition switch is
on. The engine operating temperature
will vary with changes in weather and
engine load.
If the needle moves into the red zone,
your engine is too hot. If your vehicle
overheats, stop your vehicle and allow the
engine to cool.
Your vehicle may overheat during severe
operating conditions, such as:
Driving up a long hill on a hot day.
Reducing speed or stopping after high
speed driving.
Idling for a long period with the air
conditioning on in stop−and−go traffic.
Towing a trailer.
NOTICE
Do not remove the thermostat in
the engine cooling system as this
may cause the engine to overheat.
The thermostat is designed to con-
trol the flow of coolant to keep the
temperature of the engine within
the specified operating range.
 Do not continue driving with an
overheated engine. See If your ve-
hicle overheats" in Section 4.
Tachometer
The tachometer indicates engine speed
in thousands of rpm (revolutions per
minute). Use it while driving to select
correct shift points and to prevent en-
gine lugging and over−revving.
Driving with the engine running too fast
causes excessive engine wear and poor
fuel economy. Remember, in most cases
the slower the engine speed, the greater
the fuel economy.
NOTICE
Do not let the indicator needle get
into the red zone. This may cause
severe engine damage.

(b) Overdrive switch
You can select either third gear (with
overdrive off) or fourth gear (with over-
drive on) by pushing this switch.
To turn the overdrive off, push the switch.
The O/D OFF" indicator light should come
on. To turn the overdrive on again, push
the switch again. The O/D OFF" indicator
light should go off.
Always drive your vehicle with the over-
drive on for better fuel economy and
quieter driving.
If the engine is turned off when the over-
drive is off and restarted, the overdrive
will be on automatically.Vehicles with cruise controlWhen the
cruise control is being used, even if you
downshift the transmission by pushing and
releasing the overdrive switch, engine
braking will not be enabled because the
cruise control is not cancelled.
For ways to decrease the vehicle speed,
see Cruise control" in this section.
(c) Normal driving
1. Start the engine as instructed in How to start the engine" in Section 3. The
transmission must be in P" or N".
When the front drive control lever is in
L4" (low−speed position, four−wheel
drive), the driving pattern selector setting
has no effect on gear shift timing. (See
Four−wheel drive system" in this section
for information of the front drive control
lever.)
2. With your foot holding down the brake pedal, shift the selector lever to D".
When the lever is in the D" position, the
automatic transmission system will select
the most suitable gear for running condi-
tions such as normal cruising, hill climb-
ing, hard towing, etc. Always turn the overdrive switch on for
better fuel economy and quieter driving. If
the engine coolant temperature is low or
when the front drive control lever is in
L4" (low−speed position, four−wheel
drive), the transmission will not shift into
the overdrive gear even with the overdrive
on. (See Four−wheel drive system" in this
section for information of the front drive
control lever.)
CAUTION
Never put your foot on the accelera-
tor pedal while shifting.
3. Release the parking brake and brake
pedal. Depress the accelerator pedal
slowly for smooth starting.
(d) Using engine braking
To use engine braking, you can downshift
the transmission as follows:
Push the overdrive switch. The O/D
OFF" indicator light will come on and
the transmission will downshift to third
gear.

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 in-
formation, refer to the Scheduled
Maintenance Guide" or Owner’s
Manual Supplement".
Winter driving tips
Make sure you have a proper freeze
protection of engine coolant.
Your coolant must contain ethylene−glycol
type coolant for a proper corrosion
protection of aluminum components. Use
TOYOTA 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. 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-
erhe 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 ant−
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.

Remember that when making a turn,
the trailer wheels will be closer than
the vehicle wheels to the inside of the
turn. Therefore, compensate for this by
making a larger than normal turning
radius with your vehicle.
Crosswinds and rough roads will ad-
versely affect handling of your vehicle
and trailer, causing sway. Pay attention
to the rear from time to time to pre-
pare yourself for being passed by large
trucks or buses, which may cause your
vehicle and trailer to sway. If swaying
happens, firmly grip the steering wheel
and reduce speed immediately but
gradually. Never increase speed. Steer
straight ahead. If you make no extreme
correction with the steering or brakes,
the vehicle and trailer will stabilize.
Be careful when passing other ve-
hicles. Passing requires considerable
distance. After passing a vehicle, do
not forget the length of your trailer and
be sure you have plenty of room be-
fore changing lanes.
In order to maintain engine braking effi-
ciency, do not use fifth gear (manual
transmission) or overdrive (automatic
transmission).
Because of the added load of the trail-
er, your vehicle’s engine may overheat
on hot days (at temperatures over
30C [85 F]) when going up a long or
steep grade with a trailer. If the engine
coolant temperature gauge indicates
overheating, immediately turn off the air
conditioning (if in use), pull off the road
and stop in a safe spot. Refer to If
your vehicle overheats" in Section 4.
Always place wheel blocks under both
the vehicle and trailer wheels when
parking. Apply the parking brake firmly.
Put the transmission in P" (automatic)
or in first or reverse (manual). Avoid
parking on a slope with a trailer, but
if it cannot be avoided, do so only
after performing the following:
1. Apply the brakes and hold.
2. Have someone place wheel blocks un- der both the vehicle and trailer wheels.
3. When the wheel blocks are in place, release your brakes slowly until the
blocks absorb the load.
4. Apply the parking brake firmly.
5. Shift into first or reverse (manual) or P" (automatic) and turn off the engine.
