(c) Using the 2º and Lº positions
The 2º and Lº positions are used for
strong engine braking as described pre-
viously.
With the selector lever in 2º or Lº, you
can start the vehicle in motion as with the
lever in Dº.
With the selector lever in 2º, the vehicle
will
start in the first gear and automatically
shift to the second gear.
With the selector lever in Lº, the trans-
mission is engaged in the first gear.
NOTICE
Be careful not to overrev the en- gine. Watch the tachometer to
keep engine rpm from going intothe red zone. The approximate
maximum allowable speed foreach position is given below for
your reference: 2º 126 km/h (77 mph). . . . . .
Lº 68 km/h (41 mph) . . . . .
Do not continue hill climbing or
hard towing for a long time in the
2º or Lº position. This maycause severe automatic transmis-
sion damage from overheating.To prevent such damage, Dº
position should be used in hillclimbing or hard towing.
(d) Backing up
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with
your foot, shift the selector lever to the
Rº position.
NOTICE
Never shift into reverse while the vehicle is moving.
(e) Parking
1. Bring the vehicle to a complete stop.
2. With the brake pedal pressed down, fully depress the parking brake pedal
to apply the parking brake securely.
3. With the brake pedal pressed down, shift the selector lever to the Pº posi-
tion.
While the vehicle is moving, never
attempt to move the selector lever
into Pº position under any circum-
stances. Serious mechanical dam-
age and loss of vehicle control may
result. CAUTION
!
(f) Good driving practice

If the transmission is repeatedly up-
shifted and downshifted between third
gear and overdrive when climbing a
gentle slope, the overdrive switch
should be turned off. Be sure to turn
the switch on immediately afterward.
 When towing a trailer, in order to main-
tain engine braking efficiency, do not
use overdrive.

Do not allow the engine to run atidle speed for more than 20 min-
utes.
Avoid racing the engine.
Do not push-start or pull-startyour vehicle.
Do not turn off the ignition whilethe vehicle is moving.
Keep your engine in good running
order. Malfunctions in the engine electrical system, electronic igni-
tion system/distributor ignitionsystem or fuel system engine ex-haust cautions could cause an ex-
tremely high three-way catalytic converter temperature.
If the engine becomes difficult tostart or stalls frequently, take your
vehicle in for a check-up as soon as possible. Remember, your To-
yota dealer knows your vehicleand its three-way catalytic con-verter system best.
To ensure that the three-way cata-lytic converter and the engine
emission control system operateproperly, your vehicle must re-ceive the periodic inspections re-
quired by the T oyota Maintenance
Schedule. For scheduled mainte- nance information, refer to the
separate Owner's Manual Sup-plement/Maintenance Scheduleº.CAUTION!

Avoid inhaling the engine ex-
haust. It contains carbon monox-
ide, which is a colorless and odor-
less gas. It can cause uncon-
sciousness or even death.

Make sure the exhaust system
has no holes or loose connec-
tions. The system should be
checked from time to time. If you
hit something, or notice a change
in the sound of the exhaust, have
the system checked immediately.

Do not run the engine in a garage
or enclosed area except for the
time needed to drive the vehicle in
or out. The exhaust gases cannot
escape, making this a paticularly
dangerous situation.

Do not remain for a long time in a
parked vehicle with the engine
running. If it is unavoidable, how-
ever, do so only in an unconfined
area and adjust the heating or
cooling system to force outside
air into the vehicle.
Engine exhaust cautions

133

Keep the trunk lid closed while
driving. An open or unsealed
trunk lid may cause exhaust
gases to be drawn into the ve-
hicle. If you must drive with the
trunk lid open to accommodate a
large object, close the windows,
open all the instrument panel
vents and have the heating or
cooling system deliver fresh air
into the vehicle by turning the fan
to high speed with the air intake
control button set at the outside
air mode.

To allow proper operation of your
vehicle's ventilation system, keep
the inlet grilles in front of the
windshield clear of snow, leaves,
or other obstructions.

If you smell exhaust fumes in the
vehicle, drive with the windows
open and the trunk lid closed.
Have the cause immediately lo-
cated and corrected. FUNCTIONS OF ENGINE OIL
Engine oil has the primary functions of lu-
bricating and cooling the inside of the en-
gine,
and plays a major role in maintaining
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 piston
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 com-
bustion 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 cham-
ber 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 re-
peated 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 the fuel or moisture, making it
appear that the oil level has not changed.

CAUTION

Before driving off, make sure that
the parking brake if 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 ac-
celeration 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 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 ethylene-glycol
antifreeze in the radiator.
Do not use alcohol type antifreeze.
NOTICE
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 starting.
Chapter 7-3 tells you how to visually in-
spect 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 Chapter 7-2 for recommended vis-
cosity.
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 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. To open
a frozen lock, try heating the key before in-
serting it.

Avoid jerky steering and sharp turns.
The trailer could hit your vehicle in a
tight turn. Slow down before making a
turn to avoid the necessity of sudden
braking.

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 atten-
tion 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 sta-
bilize.

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 ef-
ficiency, do not use overdrive.

Because of the added load of the trail-
er, your vehicle's engine may overheat
on hot days (at temperatures over
305C [85 5F]) 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 overheatsº in Part 4 of
this manual.

Always place wheel blocks under both
the vehicle and trailer wheels when
parking. Apply the parking brake firm-
ly. Put the transmission in Pº. 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 frimly.
5. Shift into Pº and turn off the engine.
When restarting out after parking on a
slope:
1. With the transmission in Pº position, start the engine. Be sure to keep the
brake pedal depressed.
2. Shift into the 2º, Lº or Rº position.
3. Release the parking brake and brake pedal and slowly pull or back away
from the wheels blocks. Stop and ap-
ply your brakes.
4. Have someone retrieve the blocks.ProCarManuals.com

Do not exceed 72 km/h (45 mph) or
the posted towing speed limit,
whichever is lower. Because insta-
bility (swaying) of a towing ve-
hicle-trailer combination usually
increases as the speed increases,
exceeding 72 km/h (45 mph) may
cause loss of control.

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

Avoid holding the pedal down too
long or too frequently. This could
cause the brakes to overheat and
result in reduced braking
efficiency.
CAUTION!
Getting more kilometers/mileage from a li-
ter/gallon of fuel 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 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 lenghty warm-up idling.
Once the engine is running smoothly,
begin drivingÐbut gently. Remember,
however, that on cold winter days this
may take a little longer.

Accelerate slowly and smoothly.
Avoid jackrabbit starts.

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 econ-
omy.

Maintain a moderate speed on
highways. The faster you drive, the
greater the fuel consumption. By re-
ducing 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.

If your engine coolant temperature
gauge indicates overheating, if you
experience a loss of power, or if you
hear a loud knocking or pinging noise,
the engine has probably overheated.
You should follow this procedure
0
1. Pull safely off the road, stop the ve- hicle and turn on your emergency
flashers. Put the transmission in Pº
(automatic) or neutral (manual) and
apply the parking brake. Turn off the
air conditioning if it is being used.
2. If coolant or steam is boiling out of the radiator or reservoir, stop the engine.
Wait until the steam subsides before
opening the hood. If there is no coolant
boiling over or steam, leave the engine
running and make sure the electric
cooling fan is operating. If it is not, turn
the ignition off.
To help avoid personal injury, keep
the hood closed until there is no
steam. Escaping steam or coolant is
a sign of very high pressure. CAUTION
!
3. Look for obvious coolant leaks from
the radiator, hoses, and under the ve-
hicle. However, note that water drain-
ing from the air conditioning is normal
if it has been used.
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts. CAUTION
!
4. If the coolant is leaking, stop the en-
gine immediately. Call a Toyota dealer
for assistance.
5. If there are no obvious leaks, check the coolant reservoir. If it is dry, add
coolant to the reservoir while the en-
gine is running. Fill it about half full.
Do not attempt to remove the
radiator cap when the engine and
radiator are hot. Serious injury
could result from scalding hot fluid
and steam blown out under
pressure. CAUTION
!
6. After the engine coolant temperature
has cooled to normal, again check the
coolant level in the reservoir. If
necessary, bring it up to half full again.
Serious coolant loss indicates a leak in
the system. You should have it
checked as soon as possible at your
Toyota dealer.
