If there is a problem with the instru‐ ment cluster, the drive mode will be in
ECO mode and may not change to NOR‐

ECO mode (Active ECO)
ECO
Active ECO helps
improve fuel effi‐
ciency by control‐ling certain en‐gine and trans‐axle system op‐erating parame‐ters. Fuel effi‐ciency depends
on the driver'sdriving habit and
road condition. • When the DRIVE MODE button is
pressed and the ECO mode is selec‐
ted, the ECO indicator (green) will illu‐ minate to show that the Active ECO
is operating.
• When the Active ECO is activated, it does not turn off even though the
engine is restarted again. To turn off
the system, press the DRIVE MODE button again.
When Active ECO is activated:
• The acceleration may slightly be re‐ duced even though you depress the
accelerator fully.
• The air conditioner performance may be limited.
• The shift pattern of the automatic transaxle may change.
• The engine noise may get louder.
The above situations are normal condi‐
tions when the active eco system is ac‐
tivated to improve fuel efficiency.
Limitation of Active ECO operation:
If the following conditions occur while Active ECO is operating, the system op‐
eration is limited even though there is
no change in the ECO indicator.

• When the coolant temperature is low:The system will be limited until en‐
gine performance becomes normal.
• When driving up a hill: The system will be limited to gain
power when driving uphill because the engine torque is restricted.
• When using manual mode: The system will be limited according
to the shift location.
• When the accelerator pedal is deeply depressed for a few seconds:
The system will be limited, judging
that the driver wants to speed up.
SPORT mode
SPORT
SPORT mode focu‐ ses on dynamic driv‐ing by automatically
controlling thesteering wheel, en‐gine and transaxlesystem.
• When the DRIVE MODE button is pressed and the SPORT mode is se‐
lected, the SPORT indicator (yellow) will illuminate. • Whenever the hybrid system is re‐
started, the Drive Mode will revert
back to ECO mode. If SPORT mode is
desired, re-select SPORT mode from
the DRIVE MODE button
• If the system is activated: - After speeding, it maintains the gear and RPM for some time even
though the accelerator pedal is not depressed.
- Up-shifting is delayed.
NOTICE
In Sport drive mode, the fuel effi‐
ciency may decrease.

ECONOMICAL OPERATION
Your vehicle's fuel economy depends mainly on your style of driving, where
you drive and when you drive.
Each of these factors affects how
many kilometers (miles) you can get from a liter (gallon) of fuel. To operate
your vehicle as economically as possi‐
ble, use the following driving sugges‐ tions to help save money in both fuel
and repairs: • Drive smoothly. Accelerate at a mod‐ erate rate. Do not make "jack-rabbit"
starts or full-throttle shifts and maintain a steady cruising speed. Do
not race between stop lights. Try to
adjust your speed to the traffic so
you do not have to change speeds
unnecessarily. Avoid heavy traffic whenever possible.
Always maintain a safe distance from
other vehicles so you can avoid un‐
necessary braking. This also reduces
brake wear.
• Drive at a moderate speed. The fast‐ er you drive, the more fuel your vehi‐cle uses. Driving at a moderate
speed, especially on the highway, is
one of the most effective ways to re‐
duce fuel consumption. • Do not "ride" the brake or clutch ped‐
al. This can increase fuel consumption
and also increase wear on these com‐
ponents. In addition, driving with your
foot resting on the brake pedal may
cause the brakes to overheat, which
reduces their effectiveness and may lead to more serious consequences.
• Take care of your tires. Keep them inflated to the recommended pres‐
sure. Incorrect inflation, either too
much or too little, results in unneces‐
sary tire wear. Check the tire pres‐ sures at least once a month.
• Be sure that the wheels are aligned correctly. Improper alignment can re‐
sult from hitting curbs or driving too
fast over irregular surfaces. Poor alignment causes faster tire wear
and may also result in other prob‐
lems as well as greater fuel con‐
sumption.
• Keep your vehicle in good condition. For better fuel economy and reducedmaintenance costs, maintain your ve‐
hicle in accordance with the mainte‐
nance schedule in Chapter 9, Mainte‐
nance. If you drive your vehicle in se‐
vere conditions, more frequent main‐ tenance is required (see Chapter 9,
Maintenance for details). • Keep your vehicle clean. For maxi‐
mum service, your vehicle should be
kept clean and free of corrosive ma‐ terials. It is especially important that
mud, dirt, ice, etc. not be allowed to
accumulate on the underside of the
vehicle. This extra weight can result
in increased fuel consumption and al‐ so contribute to corrosion.
• Travel lightly. Do not carry unneces‐ sary weight in your vehicle. Weight
reduces fuel economy.
• Do not let the engine idle longer than necessary. If you are waiting (and notin traffic), turn off your engine and
restart only when you're ready to go.
• Remember, your vehicle does not re‐ quire extended warm-up. After the
engine has started, allow the engine
to run for 10 to 20 seconds prior to placing the vehicle in gear. In very cold
weather, however, give your engine a
slightly longer warmup period.
• Do not "lug" or "over-rev" the engine. Lugging is driving too slowly in too
high a gear resulting engine bucking.
If this happens, shift to a lower gear. Over-revving is racing the engine be‐
yond its safe limit. This can be avoi‐
ded by shifting at the recommended
speeds.
