Driving your vehicle05
Your vehicle's fuel economy depends
mainly on your driving style such as
where you drive and when you drive.
Each of these factors affects your
fuel economy (how many miles/kilo-
meters you can drive with a
gallon/liter of fuel). To drive your vehi-
cle as economically as possible, fol-
low the below driving suggestions.
These will help you save in both the
fuel and repair expenses:
Drive smoothly. Accelerate at amoderate rate. Do not make
"jackrabbit" starts or full-throttle
shifts. Maintain a steady cruising
speed. Do not race between stop-
lights. Try to adjust your speed in
accordance with other traffic to
avoid unnecessary speed
changes. Avoid heavy traffic when-
ever possible. Always maintain a
safe distance from a vehicle in
front to avoid unnecessary braking.
This also reduces brake wear-out.
Drive at a moderate speed. The faster you drive, the more fuel your
vehicle uses. Driving at a moderate
speed, in the highest gear appro-
priate for the driving conditions
especially on the highway, is one of
the most effective ways to reduce
fuel consumption.
Do not "ride" the brake pedal. This can increase fuel consumption and
also wear out the brake compo-
nents. In addition, resting your foot
on the brake pedal, while driving,
may overheat the brake, reducing
breaking effects and possibly lead-
ing a serious consequence.
Check your tire conditions. Keep them inflated to the recommended
pressure level. Under or over infla-
tion will unnecessarily tire wear-
out. Check the tire pressures at
least once a month. Make sure that the wheels are cor-
rectly aligned. Hitting a curb or
driving too fast on uneven surfaces
may distort the wheel alignment.
Poor alignment causes faster tire
wear-out and may also result in
other problems as well as greater
fuel consumption.
Keep your vehicle in good condi- tion. For the better fuel economy
and the cheaper maintenance
expenses, maintain your vehicle in
accordance with the maintenance
schedule in the chapter 7. When
you drive your vehicle in harsh con-
ditions, more frequent mainte-
nance is required (refer to the
chapter 7 for further information).
Keep your vehicle clean. Your vehi- cle should be kept clean and away
from any corrosive substances. It is
especially important that mud, dirt,
ice and others are not daubed
under the vehicle. This extra weight
may increase the fuel consumption
and also cause corrosion.
Avoid a heavy loading. Do not carry unnecessary weight in your
vehicle. It will improve your fuel
economy.
Do not let the engine idle longer than necessary. When you wait
(not in traffic), turn OFF the engine.
Then restart the engine, when you
are ready to go.
Remember that your vehicle does not require the engine warm-up for
a long time. After turning On the
engine, run the engine for 10 to 20
seconds, before shifting the gear.
In cold weather, however, your
engine needs a slightly longer
warm-up period.

Tires
Adjust the tire inflation, as specified.
Under-inflation may overheat or
damage the tires.
Do not install worn-out or damaged
tires, which may reduce traction or
fail the braking operation.
Information
Never over-inflate your tires above the
maximum inflation pressure, as speci-
fied on your tires.
Fuel, engine coolant and engineoil
Driving at a high speed consumes
more fuel than driving in an urban
area. Do not forget to check both the
engine coolant and engine oil.
Drive belt
A loose or damaged drive belt may
overheat the engine.
i
OVI025001N
Underinflated or overinflated
tires may cause poor han-
dling, loss of vehicle control,
and sudden braking failure,
leading to an accident, an
injury, and even a death.
Always check tire pressure to
maintain the proper inflation,
before driving. For further tire
pressure information, refer to
“Tires and wheels” in the
chapter 8.
Driving with tires with insuffi- cient or extremely worn-out
tread is dangerous. Those
tires may result in loss of
vehicle control, a collision, an
injury, and even a death.
Worn-out tires must be
replaced immediately and not
used for driving. Always
check the tire tread before
driving. For further informa-
tion and tread limits, refer to
“Tires and wheels” in the
chapter 7.
WARNING

(1) Low Tire Pressure Telltale/TPMS Malfunction Indicator
(2) Low Tire Pressure Position Telltale
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard or tire inflation pressure label. (If
your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation pres-
sure label, you should determine the
proper tire inflation pressure for
those tires.)
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your
tires is significantly under-inflated. Accordingly, when the low tire pres-
sure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the
proper pressure. Driving on a signifi-
cantly under-inflated tire causes the
tire to overheat and can lead to tire
failure. Under-inflation also reduces
fuel efficiency and tire tread life, and
may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire mainte-
nance, and it is the driver’s responsi-
bility to maintain correct tire pres-
sure, even if under-inflation has not
reached the level to trigger illumina-
tion of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not oper-
ating properly. The TPMS malfunc-
tion indicator is combined with the
low tire pressure telltale. When the
system detects a malfunction, the
telltale will flash for approximately
one minute and then remain continu-
ously illuminated. This sequence will
continue upon subsequent vehicle
start-ups as long as the malfunction
exists. When the malfunction indi-
cator is illuminated, the system may
not be able to detect or signal low tire
pressure as intended. TPMS mal-
functions may occur for a variety of
reasons, including the installation of
replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.

Tire care
For the better maintenance, safety,
and fuel economy, you must always
maintain the recommended tire infla-
tion pressures, and follow the load
limits and weight distribution recom-
mendation.
Recommended cold tire infla-
tion pressures
The tire pressure (including the
spare) should be measured, when it
is cold. A “cold tire” means the vehi-
cle does not drive for the last 3 hours
or is driven shorter than 1 mile (1.6
km).
The recommended pressure must be
maintained for the best driving, han-
dling, and the minimum tire wear-out.
For the information about the recom-
mended inflation pressure, refer to
“Tire and wheels” in the chapter 8.
All specifications (sizes and pres-
sures) are specified on the label
attached to the central pillar of the
driver's door.
