Four- wheel drive modelsÐToyota
recommends not using four- wheel
drive on dry hard- surfaced roads,
because four- wheel driving will
cause unnecessary noise and wear,
and poor fuel economy.
Four- wheel drive modelsÐIn cold
temperatures, noise may occur
when driving in two- wheel drive
before the transfer 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 run-
ning.
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,
upshifting, downshifting or
braking on a slippery surface.
Sudden acceleration 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 consult 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 re-
quire a longer stopping dis-
tance, and it may pull to one
side when the brakes are ap-
plied. Also, the parking brake
will not hold the vehicle secure-
ly.

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.

CAUTION
When making the connections, to
avoid serious injury, do not lean
over the battery or accidentally
let the jumper cables or clamps
touch anything except the correct
battery terminals or the ground.
5. Start your engine in the normal
way. After starting, run it at about
2000 rpm for several minutes with
the accelerator pedal lightly de-
pressed.
6. Carefully disconnect the cables in the exact reverse order: the nega-
tive cable and then the positive
cable.
7. Carefully dispose of the battery cover clothsÐthey may now con-
tain sulfuric acid.
8. If removed, replace all the battery vent plugs.
If the cause of your battery discharg-
ing is not apparent (for example,
lights left on), you should have it
checked. If your engine stalls while driving...
1. Reduce your speed gradually, keep- ing a straight line. Move cautiously
off the road to a safe place.
2. Turn on your emergency flashers.
3. Try starting the engine again.
If the engine will not start, see ºIf
your vehicle will not startº.
CAUTION
If the engine is not running, the
power assist for the brakes and
steering will not work so steering
and braking will be much harder
than usual.
If your vehicle overheats
If your engine coolant temperature
gauge indicates overheating, if you
experience a loss of power, or if
you hear a loud knocking or ping-
ing noise, the engine has probably
overheated. You should follow this
procedure... 1. Pull safely off the road, stop the vehicle and turn on your emergen-
cy flashers. Put the transmission in
ºPº (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 sub-
sides before opening the hood. If
there is no coolant boiling over or
steam, leave the engine running.
CAUTION
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.
