1. Zoom display of odometer and trip
meter
The odometer and one of the trip meters
are displayed simultaneously. See
“—Odometer and two trip meters”.
2. Average fuel consumption (“Average Fuel Economy”)
Average fuel consumption is calculated
and displayed based on total driving
distance and total fuel consumption
with the engine running.
The displayed value is updated every 10
seconds.
To reset the calculations, push and hold
the “SELECT RESET” button for more
than 2 seconds.
3. Instantaneous fuel consumption (“Current Fuel Economy”)
The instantaneous fuel consumption is
calculated and displayed based on dis-
tance and fuel consumption at 20 revo-
lutions of the engine.
The displayed value is updated for a short
time.
An accurate figure may not be shown if
the vehicle is driving down a long slope,
and engine brake is applied. (The display
will indicate the extremely low fuel con-
sumption.) The display indicates 0 when the vehicle
is stopped with the engine running.
The calculation is reset when the engine
switch is turned off.
4. Driving range (“Distance To Empty”)
The distance the vehicle can travel with
the remaining fuel is calculated and
displayed based on the quantity of re-
maining fuel and past fuel consumption.
The driving range display indicates the
approximate distance that you can drive
until the fuel gauge reaches “E”. It is
different from the actual distance traveled.
The displayed value is updated every time
the fuel equivalent for 1 mile or 1 km is
consumed.
Every time you refuel the vehicle, the cal-
culation is reset. However, when only a
small amount of fuel is added to the tank,
the display may not be reset.
The actual driving range varies with driv-
ing habits and road conditions. If fuel con-
sumption is good, the driving range will be
longer than indicated. If fuel consumption
is poor, the driving range will be shorter
than indicated. If the low fuel level warning light comes
on, refuel the vehicle even if the display
indicates that the vehicle can be driven
further.
5. Driving time (“Trip Timer”)
To calculate the driving time, display
the “Trip Timer” after the engine has
been started. Then press the “SELECT
RESET” button. To stop the calculation,
press the “SELECT RESET” button
again.
Driving time is counted from 0:00:00. Up
to 99:59:59 (99 hours, 59 minutes and 59
seconds) can be displayed. When the driv-
ing time exceeds 99:59:59, the counter
returns to 0:00:00.
If the engine switch is turned off while the
driving time is being calculated, the cal-
culation will cease. When the engine is
next started, it will automatically resume
from the previous value.
If the “SELECT RESET” button is pressed
to cease the calculation and then the en-
gine switch is turned off, the calculation
will not resume when the engine is next
started. In this case, press the “SELECT
RESET” button to start the calculation.
To reset the calculation, push and hold
the “SELECT RESET” button for more
than 2 seconds.

Do not leave the engine running in
an area with snow buildup, or
where it is snowing. If snowbanks
build up around the vehicle while
the engine is running, exhaust
gases may collect and enter the ve-
hicle. This may lead to death or a
serious health hazard.
When taking a nap in the vehicle,
always turn the engine off. Other-
wise, you may accidentally move
the shift lever or depress the accel-
erator pedal, which could cause an
accident or fire due to engine over-
heating. Additionally, if the vehicle
is parked in a poorly ventilated
area, exhaust gases may collect and
enter the vehicle, leading to death
or a serious health hazard.
Toyota does not recommend occu-
pying the rear cargo area when it
is fitted with a slidein camper,
camper shell or other type cover
while the engine is running. This
caution applies to both driving and
stopped or parked situations with
the engine running. Particular care
should be taken to prevent exhaust
gases from entering camper bodies,
trailers or other enclosures on or
around your vehicle. If exhaust
fumes are detected, open all win-
dows and thoroughly ventilate the
area.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.

Your vehicle is designed primarily as a
passenger−and− load− carrying vehicle. Tow-
ing 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 safe-
ty and the safety of others, you must not
overload your vehicle or trailer. Ask your
local Toyota dealer for further details be-
fore towing.
NOTICE
When towing a trailer, be sure to con-
sult your Toyota dealer for further in-
formation on additional requirements
such as a towing kit, etc.
CAUTION
To tow a trailer safely, use extreme
care and drive the vehicle in accor-
dance with the trailer ’s characteristics
and operating conditions.
The vehicle stability and braking per-
formance are affected by trailer sta-
bility, brake setting and performance,
and the hitch.
Follow all the instructions described
in this section. Failure to do so could
cause an accident resulting in death
or serious injury.
WEIGHT LIMITS
Before towing, make sure the gross
trailer weight, gross combination
weight, gross vehicle weight, gross axle
weight and trailer tongue load are all
within the limits.
The gross 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.

Improving fuel economy 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 page
553 in 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 warmup idling. Once
the engine is running smoothly, begin
driving—but gently. Remember, howev-
er, that on cold winter days this may
take a little longer.
Put the selector lever into the “D”
when engine braking is not required.
Driving with the selector lever in a
position other than “D” will reduce the
fuel economy (For details, see
“Automatic transmission” on page 211
in Section 1− 7.)
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 lugging or overrev-
ving. 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 brake ped-
al. This causes premature wear, over-
heating and poor fuel economy.
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.
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.
Keep the bottom of your vehicle free
from mud, etc. This not only lessens
weight but also helps prevent corrosion
Keep your vehicle tunedup and in
top shape. A dirty air cleaner,
improper valve clearance, dirty plugs,
dirty oil and grease,brakes not
adjusted, etc. all lower engine
performance and contribute to poor fuel
economy. For longer life of all parts
and lower operating costs, keep all
maintenance work on schedule, and if
you often drive under severe
conditions, see that your vehicle
receives more frequent maintenance.
(For scheduled maintenance
information, please refer to the
“Scheduled Maintenance Guide” or
“Owner ’s Manual Supplement”.)
