Keep the trunk lid closed while
driving. An open or unsealed trunk
lid may cause exhaust gases to be
drawn into the vehicle.

To allow proper operation of your
vehicle's ventilation system, keep
the inlet grilles in front of the wind-
shield clear of snow, leaves, or oth-
er obstructions.

If you smell exhaust fumes in the
vehicle, drive with the windows
open and the trunk lid 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 main-
taining the engine in proper working order.
ENGINE OIL CONSUMPTION
It is normal that an engine should con-
sume some engine oil during normal
engine operation. The causes of oil
consumption in a normal 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 pis-
ton moves downwards in the cylinder.
High negative 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 cylinder wall is burned
by the high temperature 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 combustion chamber
together with the intake air and is
burned along with the fuel. High tem-
perature exhaust gases also burn the
oil used to lubricate the exhaust valve
stems.
The amount of engine oil consumed de-
pends on the viscosity of the oil, the
quality of the oil and the conditions the
vehicle is driven under.
More oil is consumed by high- speed driv-
ing and frequent acceleration and decel-
eration.
A new engine consumes more oil, since
its pistons, piston rings and cylinder walls
have not become conditioned.
When judging the amount of oil con-
sumption, 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 nor-
mal 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.

Do not use your parking brake when
there is a possibility it could freeze.
When parking, put the transmission into
Pº (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- carrying vehicle. Towing 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
safety and the safety of others, you must
not overload your vehicle or trailer. Toyota
warranties do not apply to damage or
malfunction caused by towing a trailer for
commercial purposes. Ask your local
Toyota dealer for further details before
towing.
WEIGHT LIMITS
Before towing, make sure the total trail-
er 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 total trailer weight (trailer
weight plus its cargo load) must
not exceed 680 kg (1500 lb.). Ex-
ceeding this weight is dangerous.

CAUTION

Do not exceed 72 km/h (45 mph) or
the posted towing speed lim-
it,whichever is lower. Because insta-
bility (swaying) of a towing vehicle-
trailer combination usually in-
creases as the speed increases, ex-
ceeding 72 km/h (45 mph) may
cause loss of control.

Slow down and downshift before
descending steep or long downhill
grades. Do not make sudden down-
shifts.

Avoid holding the brake pedal down
too long or too frequently. This
could cause the brakes to overheat
and result in reduced braking effi-
ciency.
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 Section
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.

Keep the automatic transmission
overdrive turned on when engine
braking is not required. Driving with
the overdrive off will reduce the fuel
economy. (For details, see Automatic
transmissionº in Section 1- 6.)

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 premature
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.

Manual transmission
The shift pattern is conventional as
shown above.
Press the clutch pedal down fully while
shifting, and then release it slowly. Do not
rest your foot on the pedal while driving,
because it will cause clutch trouble. And
do not use the clutch to hold the vehicle
when stopped on an uphill gradeÐuse the
parking brake.
Recommended shifting speeds
The transmission is fully synchronized and
upshifting or downshifting is easy.
For the best compromise between fuel
economy and vehicle performance, you
should upshift or downshift at the following
speeds:Low altitude
Ð1219 m (4000 ft.) or lower
gear km/h (mph)
1 to 2 or 2 to 1 24 (15)
2 to 3 or 3 to 2 37/40
*
1(23/25*
1)
3 to 4 or 4 to 3 64/45*
2(40/28*
2)
4 to 5 or 5 to 4 72/64*
2(45/40*
2)
*
1: Under cold engine conditions.*
2: For constant- speed cruise or
constant- speed cruise after deceleration.
High altitude
ÐHigher than 1219 m (4000 ft.)
Upshifting
gear km/h (mph)
1 to 2 24 (15)
2 to 3 40 (25)
3 to 4 64 (40)
4 to 5 72 (45)
Downshifting
gear km/h (mph)
2 to 1 24 (15)
3 to 2 40 (25)
4 to 3 64 (40)
5 to 4 72 (45)Downshift to the appropriate gear if accel-
eration is needed when you are cruising
below the above downshifting speeds.
Upshifting too soon or downshifting too
late will cause lugging, and possibly ping-
ing. Regularly revving the engine to maxi-
mum speed in each gear will cause ex-
cessive engine wear and high fuel
consumption.
Maximum allowable speeds
To get on a highway or to pass slower
traffic, maximum acceleration may be nec-
essary. Make sure you observe the follow-
ing maximum allowable speeds in each
gear:
gear km/h (mph)
1 55 (34)
2 92 (57)
3 134 (83)
4 180 (112)
NOTICE
Do not downshift if you are going
faster than the maximum allowable
speed for the next lower gear.
