“H” mode (high speed position, two
wheel drive): Front drive control lever at
“H”, “4WD” button left out
Use this for normal driving on dry hard
surfaced roads. This position gives greater
economy, quietest ride and least wear and
better vehicle control.
“H” mode (high speed position, four
wheel drive, center differential un-
locked): Front drive control lever at “H”,
“4WD” button push in, center differential
lock switch left out
Use this for normal driving on all types of
roads, from dry hardsurfaced roads to
wet, icy or snowcovered roads. This
position provides greater traction than
twowheel drive.
“H” (high speed position, fourwheel
drive, center differential locked): Lever
at “H”, “4WD” button pushed in center
differential lock switch pushed in
Use this for greater traction when you
experience a loss of power, such as
wheel slipping, in the center differential
unlock mode.“N” mode (neutral position): Front drive
control lever at “N”
No power is delivered to the wheels. The
vehicle must be stopped.
“L4” (low speed position, fourwheel
drive, center differential unlocked):
Front drive control lever at “L4”, center
differential lock switch left out
Use this for maximum power and traction.
Use this for climbing steep hills, offroad
driving, and hard pulling in sand or mud.
In this mode, the braking feeling that oc-
curs when the wheels are negotiating a
sharp corner is further reduced than in the
“L4” (low position, fourwheel drive, center
differential locked) mode.
The transmission automatically shifts up
from second gear in this mode. This sys-
tem is effective when starting your vehicle
in sand, mud, ice or snow. (However, the
transmission system may shift up from
first gear when the vehicle starts too
quickly.)“L4” mode (low speed position, four
wheel drive, center differential locked):
Front drive control lever at “L4”, center
differential lock switch push in
Use this for maximum power and traction.
Use this for hard pulling in situations the
vehicle cannot negotiate even in the “L4”
(low speed position, fourwheel drive, cen-
ter differential unlocked) mode. Also, using
this mode when driving down steep off
road inclines will help contribute to in-
creased vehicle stability.
Fourwheel drive and center differential
lock indicator lights show which transfer
and center differential mode the vehicle is
in. Note that the differential is not still
locked as long as the indicator light re-
mains off.
When the shifting has not been completed
within 3 seconds after the shifting opera-
tion, the indicator flashes. If the indicator
light does not go off when you push out
the center differential lock button, drive
straight ahead while accelerating or decel-
erating, or drive in reverse. If the indicator
flashes even if doing so, contact your
Toyota dealer as soon as possible. There
may be a trouble in the center differential
lock system.
See “(c) Shifting procedure” for further in-
structions.

RESUMING THE PRESET SPEED
If the preset speed is cancelled by pulling
the control lever or by depressing the
brake pedal or clutch pedal, pushing the
lever up in the “RES/ACC” direction will
restore the speed set prior to cancellation.
However, once the vehicle speed falls be-
low about 40 km/h (25 mph), the preset
speed will not be resumed.
CRUISE CONTROL FAILURE WARNING
If the “CRUISE” indicator light in the
instrument cluster flashes when using the
cruise control, press the “CRUISE ON
OFF” button to turn the system off and
then press it again to turn it on.
If any of the following conditions then oc-
curs, there is some trouble in the cruise
control system.
The indicator light does not come on.
The indicator light flashes again.
The indicator light goes out after it
comes on.
If this is the case, contact your Toyota
dealer and have your vehicle inspected.

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 highspeed 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.The diluting ingredients evaporate out
when the vehicle is then driven at high
speeds, as on an expressway, making it
appear that oil is excessively consumed
after driving at high speeds.
IMPORTANCE OF ENGINE OIL LEVEL
CHECK
One of the most important points in prop-
er vehicle maintenance is to keep the en-
gine oil at the optimum level so that oil
function will not be impaired. Therefore, it
is essential that the oil level be checked
regularly. Toyota recommends that the oil
level be checked every time you refuel
the vehicle.
NOTICE
Failure to check the oil level regularly
could lead to serious engine trouble
due to insufficient oil.
For detailed information on oil level check,
see “Checking the engine oil level” in Sec-
tion 72.
Your engine is fitted with twin ground
electrode spark plugs.
NOTICE
Use only twin ground electrode spark
plugs and do not adjust gaps for your
engine performance.

Maintenance requirements
Your Toyota vehicle has been designed for
fewer maintenance requirements with long-
er service intervals to save both your time
and money. However, each regular mainte-
nance, as well as daytoday care, is
more important than ever before to ensure
smooth, and troublefree, safe, and eco-
nomical drivings.
It is the owner ’s responsibility to make
sure the specified maintenance, including
general maintenance service, is performed.
Note that both the new vehicle and emis-
sion control system warranties specify that
proper maintenance and care must be per-
formed. See “Owner ’s Warranty Informa-
tion Booklet” or “Owner ’s Manual Supple-
ment” for complete warranty information.
General maintenance
General maintenance items are those day
today care practices that are important to
your vehicle for proper operation. It is the
owner ’s responsibility to ensure that the
general maintenance items are performed
regularly.
These checks or inspections can be done
either by yourself or a qualified technician,
or if you prefer, your Toyota dealer will be
pleased to do them at a nominal cost.Scheduled maintenance
The scheduled maintenance items listed in
the “Scheduled Maintenance Guide” or
“Owner ’s Manual Supplement” are those
required to be serviced at regular inter-
vals.
For details of your maintenance schedule,
read the “Scheduled Maintenance Guide”
or “Owner ’s Manual Supplement”.
It is recommended that any replacement
parts used for maintenance or for the
repair of the emission control system
be Toyota supplied.
The owner may elect to use nonToyota
supplied parts for replacement pur-
poses without invalidating the emission
control system warranty. However, use
of replacement parts which are not of
equivalent quality may impair the effec-
tiveness of the emission control sys-
tems.
You may also elect to have mainte-
nance, replacement, or repair of the
emission control devices and system
performed by any automotive repair es-
tablishment or individual without invali-
dating this warranty. See “Owner’s War-
ranty Information Booklet” or “Owner’s
Manual Supplement” for complete war-
ranty information.Where to go for service?
Toyota technicians are welltrained spe-
cialists and are kept up to date with the
latest service information through technical
bulletins, service tips, and indealership
training programs. They learn to work on
Toyotas before they work on your vehicle,
rather than while they are working on it.
You can be confident that your Toyota
dealer ’s service department performs the
best job to meet the maintenance require-
ments on your vehicle—reliably and eco-
nomically.
Your copy of the repair order is proof that
all required maintenance has been per-
formed for warranty coverage. And if any
problems should arise with your vehicle
while under warranty, your Toyota dealer
will promptly take care of it. Again, be
sure to keep a copy of the repair order
for any service performed on your Toyota.
What about doityourself maintenance?
Many of the maintenance items are easy
to do yourself if you have a little mechani-
cal ability and a few basic automotive
tools. Simple instructions for how to per-
form them are presented in Section 7.
