2002 TOYOTA PRIUS Owners Manual

164
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 consult 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 lon-
ger stopping distance, and it may
pull to one side when the brakes
are applied. Also, the parking brake
will not hold the vehicle securely.
Make sure you have a proper freeze
protection of 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 210 page in Section 8 −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 auxiliary
battery and cables.
Cold temperatures reduce the capacity of
any auxiliary battery, so it must be in top
shape to provide enough power for winter
starting. Section 8 −3 tells you how to
visually inspect the auxiliary battery. Your
Toyota dealer will be pleased to check the
level of charge. Make sure the engine oil viscosity is
suitable for the cold weather.
See 209 page in Section 8
−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—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.
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 as washer fluid be-
cause it may damage your vehicle’s
paint.
Winter driving tips

165
Do not use your parking brake when
there is a possibility it could freeze.
When parking, put the selector lever into
“P” and block the rear wheels. Do not use
the parking brake, or snow or water accu-
mulated 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.
40p050
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 ve-
hicle.
40p003a
Toyota does not recommend towing a
trailer with your Toyota. It is not de-
signed for trailer towing.

Improving fuel economy is easy−just 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 page
214 in Section 8 −2 for instructions.
Do not carry unneeded weight in
your vehicle. Excess weight puts a
heavier load on the engine, causing
greater fuel consumption.
Accelerate slowly and smoothly.
Avoid jackrabbit starts.
Avoid continuous speeding up and
slowing down. Stop−and− go driving
wastes power.
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 brake ped-
al. This causes premature wear, over-
heating and poor fuel economy.
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 tunedup 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 con-
tribute 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 ve-
hicle receives more frequent mainte-
nance.
CAUTION
Never turn off the hybrid system to
coast down hills. Your power steering
and brake booster will not function
without the hybrid system running.
Also, the emission control system op-
erates properly only when the hybrid
system is running.

Before making these checks, make sure
you have followed the correct starting
procedure given in ”How to start the
hybrid system” on page 162 in Section 4
and that you have sufficient fuel. Also
check whether the other keys will start the
hybrid system. If they work, your key may
be broken. Have the key checked at your
Toyota dealer. If none of your keys work,
the hybrid vehicle immobiliser system is
possibly broken. Call your Toyota dealer.
(See ”Keys” on page 18 in Section 2−1.)
If the instrument cluster dims or the
instrument cluster display turns off
with the ignition switch on— 1. Check that the auxiliary battery termi- nals are tight and clean.
2. If the auxiliary battery terminals are O.K., the auxiliary battery is dis-
charged. You may try jump starting.
See “(b) Jump starting” for further in-
structions.
NOTICE
Hybrid vehicles cannot be push
started.
If the instrument cluster is shown in
appropriate brightness with the ignition
switch turned to on—
The hybrid vehicle system is suspected to
be faulty. Contact your Toyota dealer. If the auxiliary battery is discharged,
the hybrid system can be started by
jump starting. Depending on the the ve-
hicle condition, the engine may not
start.
To avoid serious personal injury and
damage to your vehicle which might re-
sult from battery explosion, acid burns,
electrical burns, or damaged electronic
components, these instructions must be
followed precisely.
If you are unsure about how to follow this
procedure, we strongly recommend that
you seek the help of a competent qualified
technician or towing service.
If your vehicle will not start—
(a) Simple checks
(b) Jump starting

169
CAUTION
Auxiliary battery and booster bat-
tery contain sulfuric acid which is
poisonous and corrosive. Wear pro-
tective safety glasses when jump
starting, and avoid spilling acid on
your skin, clothing, or vehicle.
If you should accidentally get acid
on yourself or in your eyes, remove
any contaminated clothing and flush
the affected area with water for im-
mediately. Then get immediate med-
ical attention. If possible, continue
to apply water with a sponge or
cloth while en route to the medical
office.
The gas normally produced by a
battery will explode if a flame or
spark is brought near. Use only
standardized jumper cables and do
not smoke or light a match while
jump starting.
Warning: Battery posts, terminals and
related accessories contain lead and
lead compounds, chemicals known to
the State of California to cause can-
cer and reproductive harm. Wash
hands after handling.
NOTICE
The battery used for boosting must
be 12 V. Do not jump start unless you
are sure that the booster battery is
correct.

5. Remove the positive terminal cover ofthe auxiliary battery.
6. If the booster battery is installed in another vehicle, make sure the ve-
hicles are not touching. Turn off all
unnecessary lights and accessories.
7. If required, remove all the vent plugs from the booster batteries. Lay a cloth
over the open vents on the batteries.
(This helps reduce the explosion haz-
ard, personal injuries and burns.) 8. If the engine in the vehicle with the
booster battery is not running, start it
and let it run for a few minutes. During
jump starting, run the engine at about
2000 rpm with the accelerator pedal
lightly depressed.

CAUTION
When making the connections, to
avoid serious injury, do not lean over
the battery or accidentally let the
jumper cables or clamps touch any-
thing except the correct battery termi-
nals or the ground.
10. Start the hybrid system. Make sure the “READY” light is on. If the hybrid ve-
hicle battery warning light comes on in
the multi −information display, the hybrid
vehicle battery is also discharged. Con-
tact your Toyota dealer.
11. Carefully disconnect the cables in the exact reverse order: the negative cable
and then the positive cable.
12. Carefully dispose of the battery cover cloths—they may now contain sulfuric
acid.
13. If removed, replace all the battery vent plugs.
If the cause of your auxiliary battery dis-
charging is not apparent (for example,
lights left on), you should have it checked.
