Brake system
TANDEM MASTER CYLINDER BRAKE SYSTEM
The tandem master cylinder brake system
is a hydraulic system with two separate
sub- systems. If either sub- system s
hould
fail, the other will still work. However, the
pedal will be harder to press, and your
stopping distance will be longer. Also, the
brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a
single brake system. Have your
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses engine vacuum to
power- assist the brakes. If the engine
should quit while you are driving, you can
bring the vehicle to a stop with normal
pedal pressure. There is enough reserve
vacuum for one or two stopsÐbut no
more!
CAUTION
Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your vacuum reserve.
Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hardÐmuch harder than nor-
mal. And your braking distance will
be longer.
ANTI- LOCK BRAKE SYSTEM
(with ºABSº warning light)
The anti- lock brake system is designed to
automatically help prevent lock- up of the
wheels during sudden braking or braking
on slippery road surfaces. This assists in
providing directional stab ility and steering
performance of the vehicle under these
circumstances.
The anti- lock brake system becomes op-
erative after the vehicle has accelerated
to a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph).
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
is started. This means that the anti- lock
brake system is in the self check mode,
and does not indicate a malfunction.
Effective way to press the ºABSº brake
pedal: When the anti- lock brake system
function is in action, you may feel the
brake pedal pulsating and hear a noise.
In this situation, to let the anti- lock
brake system work for you, just hold the
brake pedal down more firmly. Do not
pump the brake in a panic stop. Pump-
ing the brake pedal makes the stopping
distance longer.
The brake pedal pulsation caused by the
anti- lock brake system may indicate haz-
ardous road surface conditions. Although
the anti- lock brake system assists in pro-
viding vehicle control, it is still important
to drive with all due care, because the
anti- lock brake system cannot overcome
the laws of physics that act on your ve-
hicle: Braking capab ility is dependent on tire
friction with the road surface.
Even though the anti- lock brake sys-
tem is operating, a driver cannot main-
tain full control on certain slippery road
surfaces, when cornering at high
speeds, or in violent maneuvers.

Four- wheel drive modelsÐToyota rec-
ommends not using four- wheel drive on
dry hard- surfaced roads, because four-
wheel driving will cause unnecessary
noise and wear, and poor fuel econo-
my.
Four- wheel drive modelsÐIn cold tem-
peratures, noise may occur when driv-
ing in two- wheel drive before the trans-
fer 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 high- speed 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 high- speed 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.

Do not use your parking brake when
there is a possibility it could freeze.
When parking, put the transmission into
ºPº (automatic) or into first or reverse
(manual) and block the rear 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.
Trailer towing
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, durab
ility
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.
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 a highway weighing station, build-
ing supply company, trucking company,
junk yard, etc.
CAUTION
The maximum gross trailer weight
(trailer weight plus cargo weight)
must never exceed the following.
3RZ- FE engine1587 kg (3500 lb.)
5VZ- FE engine 2267 kg (5000 lb.)
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. Two- wheel drive models3RZ- FE engine 3447 kg (7600 lb.)
5VZ- FE engine 3992 kg (8800 lb.)
Four- wheel drive models 3RZ- FE engine 3583 kg (7900 lb.)
5VZ- FE engine 4173 kg (9200 lb.)

Getting more kilometers/mileage from a
liter/gallon of fuel is easyÐjust take it
easy. It will help make your vehicle last
longer, too. Here are some specific tips
on how to save money on both fuel and
repairs:
Keep your tires inflated at the cor-
rect pressure. Underinflation causes
tire wear and wastes fuel. See Chapter
7- 2 for instructions.
Do not carry unneeded weight in
your vehicle. Excess weight puts a
heavier load on the engine, causing
greater fuel consumption.
Avoid lengthy warm- up idling. Once
the engine is running smoothly, begin
drivingÐbut gently. Remember, howev-
er, that on cold winter days this may
take a little longer.
Accelerate slowly and smoothly.
Avoid jackrabbit starts. Get into high
gear as quickly as possible.
Avoid long engine idling. If you have
a long wait and you are not in traffic,
it is better to turn off the engine and
start again later.
Avoid engine lug or overrevving. Use
a gear position suitable for the road on
which you are travelling.
Avoid continuous speeding up and
slowing down. Stop- and- go driving
wastes fuel.
Avoid unnecessary stopping and
braking. Maintain a steady pace. Try
to time the traffic signals so you only
need to stop as little as possible or
take advantage of through streets to
avoid traffic lights. Keep a proper dis-
tance from other vehicles to avoid sud-
den braking. This will also reduce wear
on your brakes.
Avoid heavy traffic or traffic jams
whenever possible.
Do not rest your foot on the clutch
or brake pedal. This causes needless
wear, overheating and poor fuel econo-
my.
Maintain a moderate speed on high-ways. The faster you drive, the greater
the fuel consumption. By reducing your
speed, you will cut down on fuel con-
sumption.
Keep the front wheels in proper
alignment. Avoid hitting the curb and
slow down on rough roads. Improper
alignment not only causes faster tire
wear but also puts an extra load on
the engine, which, in turn, wastes fuel.
Keep the bottom of your vehicle free
from mud, etc. This not only lessens
weight but also helps prevent corro-
sion.
Keep your vehicle tuned- up and in
top shape. A dirty air cleaner, improp-
er valve clearance, dirty plugs, dirty oil
and grease,brakes not adjusted, etc. all
lower engine performance and contrib-
ute to poor fuel economy. For longer
life of all parts and lower operating
costs, keep all maintenance work on
schedule, and if you often drive under
severe conditions, see that your vehicle
receives more frequent maintenance.
(For scheduled maintenance informa-
tion, please refer to the separate
ºScheduled Maintenance Guideº or
ºOwner 's Manual Supplementº).
CAUTION
Never turn off the engine to coast
down hills. Your power steering and
brake booster will not function with-
out the engine running. Also, the
emission control system operates
properly only when the engine is run-
ning.

(a) Towing with wheel lift type truckÐÐFrom front
ÐFrom rear
(b) Using flat bed truck
Four- wheel drive models If towing is necessary, we recom-
mended you to have it done by your
Toyota dealer or a commercial tow
truck service. In consultation with them,
have your vehicle towed using either (a)
or (b).
Only when you cannot receive a towing
service from a Toyota dealer or com-
mercial tow truck service, tow your ve-
hicle carefully in accordance with the
instructions given in ºÐEmergency tow-
ingº in this part.
Proper equipment will help ensure that
your vehicle is not damaged while being
towed. Commercial operators are generally
aware of the state/provincial and local
laws pertaining to towing.
Your vehicle can be damaged if it is
towed incorrectly. Although most operators
know the correct procedure, it is possible
to make a mistake. To avoid damage to
your vehicle, make sure the following few
precautions are observed. If necessary,
show this page to the tow truck driver.
TOWING PRECAUTIONS:
Use a safety chain system for all towing,
and abide by the state/provincial and local
laws. The wheels and axle on the ground
must be in good condition. If they are
damaged, use a towing dolly.
Two- wheel drive modelsÐ
(a) Towing with wheel lift type truck
From frontÐ
Manual transmission:
We recommend using a towing dolly un-
der the rear wheels. If you do not use
a towing dolly, release the parking brake
and put the transmission in neutral.
Automatic transmission:
Use a towing dolly under the rear wheels.
NOTICE
Never tow a vehicle with an automatic
transmission from the front with therear wheels on the ground, as this may cause serious damage to the
transmission.

From rearÐ
Place the ignition key in the
ºACCº position.
NOTICE
When lifting wheels, take care to
ensure adequate ground clearancefor towing at the opposite end of the raised vehicle. Otherwise, the
bumper and/or underbody of thetowed vehicle will be damaged dur-ing towing.
Do not tow with the key removed orin the ºLOCKº position, as the steering lock mechanism is not
strong enough to hold the frontwheels straight while towing.
(b) Using flat bed truck Four- wheel drive modelsÐ
(a) Towing with wheel lift type truck
From frontÐ
Manual transmission:
We recommend using a towing dolly
under the rear wheels. If you do not
use a towing dolly, release the parking
brake, put the transmission in neutral
and the transfer in ºH2º.
Automatic transmission:
Use a towing dolly under the rear
wheels.
NOTICE
Never tow a vehicle with an automatic
transmission from the front with therear wheels on the ground, as this
may cause serious damage to the
transmission.
From rearÐ We recommend using a tow-
ing dolly under the front wheels. If you do
not use a towing dolly, place the ignition
key in the ºACCº position, put the trans-
mission in neutral and the transfer in
ºH2º.
NOTICE
Do not tow with the key removed or
in the ºLOCKº position when towingfrom the rear without a towing dolly. The steering lock mechanism is not
strong enough to hold the frontwheels straight.
(b) Using flat bed truck

4RUNNER ()211
(c) Towing with sling type truck
All modelsÐ
(c) Towing with sling type truck
NOTICE
Do not tow with sling type truck, ei- ther from the front or rear. This maycause body damage.
ÐEmergency towing
If towing is necessary, we recommend
you to have it done by your Toyota
dealer or a commercial tow truck ser-
vice.
If towing service is not available in an
emergency, your vehicle may be tempo-
rarily towed by a cable or chain se-
cured to the emergency towing hook.
Use extreme caution when towing ve-
hicles. Four- wheel drive modelsÐBefore towing,
remove the towing hook cover in front of
the emergency towing hook. By doing this,
it prevents the towing cable from damag-
ing the bumper. See ºÐRemoving towing
hook cover for emergency towingº for in-
structions.
A driver must be in the vehicle to steer
it and operate the brakes.
Towing in this manner may be done only
on hard- surfaced roads for a short dis-
tance and at low speeds. Also, the
wheels, axles, drive train, steering and
brakes must all be in good condition.
CAUTION
Use extreme caution when towing ve-
hicles. Avoid sudden starts or erratic
driving maneuvers which would place
excessive stress on the emergency
towing hook and towing cable or
chain. The hook and towing cable or
chain may break and cause serious
injury or damage.

1. Rinse off loose dirt with a hose. Re-
move any mud or road salt from the
underside of the vehicle or in the
wheel wells.
2. Wash with a mild car- wash soap, mixed according to the manufacturer 's
instructions. Use a soft cotton mitt and
keep it wet by dipping it frequently into
the wash water. Do not rub hardÐlet
the soap and water remove the dirt.
Aluminum wheels: Use only a mild soap
or neutral detergent.
Road tar: Remove with turpentine or
cleaners that are marked safe for painted
surfaces.
NOTICE
Do not use gasoline or strong sol- vents, which may be toxic or causedamage.
3. Rinse thoroughlyÐdried soap can cause streaking. In hot weather you
may need to rinse each section right
after you wash it.
4. To prevent water spots, dry the vehicle using a clean soft cotton towel. Do not
rub or press hardÐyou might scratch
the paint. Automatic car wash
Your vehicle may be washed in an auto-
matic car wash, but remember that the
paint can be scratched by some type of
brushes, unfiltered washing water, or the
washing process itself. Scratching reduces
paint durability and gloss, especially on
darker colors. The manager of the car
wash should be able to advise you wheth-
er the process is safe for the paint on
your vehicle.
NOTICE
To prevent damage to the antenna,
make sure it is retracted before driv-ing your Toyota through an automatic car wash. On models with detachable
antenna, remove the antenna beforeusing an automatic car wash.
Waxing your Toyota
Polishing and waxing is recommended
to maintain the original beauty of your
Toyota's finish.
Once a month or if the vehicle does not
repel water well, apply wax.
1. Always wash and dry the vehicle be- fore you begin waxing, even if you are
using a combined cleaner and wax.
2. Use a good quality polish and wax. If the finish has become extremely weath-
ered, use a car- cleaning polish, fol-
lowed by a separate wax. Carefully fol-
low the manufacturer 's instructions and
precautions. Be sure to polish and wax
the chrome trim as well as the paint.
3. Wax the vehicle again when water does not bead but remains on the sur-
face in large patches.
