acceleration is needed when you are
cruising below the above downshifting
speeds.
Upshifting too soon or downshifting
too late will cause lugging and, possi-
bly, pinging. Regularly revving the en-
gine to maximum speed in each gear
will cause excessive engine wear and
high fuel consumption.
Maximum allowable speeds
To get on a highway or to pass slow-
er traffic, maximum acceleration may
be necessary. Make sure you observe
the following maximum allowable
speeds in each gear:

Keep the back door and back
window closed while driving. An
open or unsealed back door and
back window, may cause ex-
haust gases to be drawn into
the vehicle. If you must drive
with the trunk lid open to ac-
commodate a large object, close
the windows, open all the
instrument panel vents and
have the heating or cooling sys-
tem deliver fresh air into the
vehicle by turning the fan to
high speed with the air intake
control set at the outside air
position.
To allow proper operation of
your vehicle's ventilation sys-
tem, keep the inlet grilles in
front of the windshield clear of
snow, leaves, or other obstruc-
tions.
If you smell exhaust fumes in
the vehicle, drive with the win-
dows open and the back door
and back window closed. Have
the cause immediately located
and corrected.FUNCTIONS OF ENGINE OIL
Engine oil has the primary functions
of lubricating and cooling the inside of
the engine, and plays a major role in
maintaining the engine in proper work-
ing order.
ENGINE OIL CONSUMPTION
It is normal that an engine should
consume some engine oil during
normal engine operation. The
causes of oil consumption in a nor-
mal engine are as follows.
Oil is used to lubricate pistons,
piston rings and cylinders. A thin
film of oil is left on the cylinder
wall when a piston moves down-
wards in the cylinder. High nega-
tive pressure generated when the
vehicle is decelerating sucks some
of this oil into the combustion
chamber. This oil as well as some
part of the oil film left on the cylin-
der wall is burned by the high tem-
perature combustion gases during
the combustion process.
Oil is also used to lubricate the
stems of the intake valves. Some
of this oil is sucked into the com-
bustion chamber together with the
intake air and is burned along with
the fuel. High temperature exhaust
gases also burn the oil used to
lubricate the exhaust valve stems.
The amount of engine oil consumed
depends on the viscosity of the oil,
the quality of the oil and the condi-
tions the vehicle is driven under.
More oil is consumed by high- speed
driving and frequent acceleration and
deceleration.
A new engine consumes more oil,
since its pistons, piston rings and cyl-
inder walls have not become condi-
tioned.
When judging the amount of oil
consumption, note that the oil may
become diluted and make it difficult
to judge the true level accurately.
As an example, if a vehicle is used
for repeated short trips, and consumes
a normal amount of oil, the dipstick
may not show any drop in the oil
level at all, even after 1000 km (600
miles) or more. This is because the
oil is gradually becoming diluted with
fuel or moisture, making it appear that
the oil level has not changed.

Use a washer fluid containing an
antifreeze solution.
This product is available at your Toyo-
ta 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 itmay damage your vehicle's paint.
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 accumulat-
ing 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 driv-
ing, we recommend you carry some
emergency 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 ve-
hicle. Towing a trailer will have an
adverse effect on handling, perfor-
mance, braking, durability and driving
economy (fuel consumption, etc.).
Your safety and satisfaction depend
on the proper use of correct equip-
ment and cautious driving habits. For
your safety and the safety of others,
you must not overload your vehicle or
trailer. Ask your local Toyota dealer
for further details before towing.
WEIGHT LIMITS
Before towing, make sure the total
trailer 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, building supply company,
trucking company, junk yard, etc.

Slow down and downshift be-
fore descending steep or long
downhill grades. Do not make
sudden downshifts.
Avoid holding the brake pedal
down too long or too frequent-
ly. This could cause the brakes
to overheat and result in re-
duced braking efficiency.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 specif-
ic tips on how to save money on both
fuel and repairs:
Keep your tires inflated at the
correct 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, caus-
ing greater fuel consumption.
Avoid lengthy warm- up idling.
Once the engine is running smooth-
ly, begin drivingÐbut gently. Re-
member, however, that on cold win-
ter 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 distance from
other vehicles to avoid sudden
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 economy.
Maintain a moderate speed on
highways. The faster you drive,
the greater the fuel consumption.
By reducing your speed, you will
cut down on fuel consumption.
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.
