3. Pull the fuel filler door (1) out tofully open.
4. To remove the fuel tank cap (2), turn it anticlockwise. You may hear
a hissing noise as the pressure
inside the tank equalizes.
5. Place the cap on the fuel filler door.
Information
If the fuel filler door does not open
because ice has formed around it, tap
lightly or push on the door to break
the ice and release the door. Do not
pry on the door. If necessary, spray
around the door with an approved de-
icer fluid (do not use radiator anti-
freeze) or move the vehicle to a warm
place and allow the ice to melt.
Closing the fuel filler door
1. To install the fuel tank cap, turn it clockwise until it “clicks” one time.
2. Close the fuel filler door until it is latched securely.

Petrol is highly flammable and
explosive. Failure to follow
these guidelines may result in
SERIOUS INJURY or DEATH:
Read and follow all warnings
posted at the gas station.
Before refuelling, note the
location of the Emergency
Petrol Shut-Off, if available, at
the gas station.
Before touching the fuel noz-
zle, you should eliminate the
potential build-up of static
electricity by touching a metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other gas
source, with your bare hand.

Do not use mobile phones
whilst refuelling. Electric cur-
rent and/or electronic interfer-
ence from mobile phones can
potentially ignite fuel vapours
and cause a fire.
Do not get back into a vehicle
once you have begun refu-
elling. You can generate a
build-up of static electricity by
touching, rubbing or sliding
against any item or fabric capa-
ble of producing static electric-
ity. Static electricity discharge
can ignite fuel vapours causing
a fire. If you must re-enter the
vehicle, you should once again
eliminate potentially danger-
ous static electricity discharge
by touching a metal part of the
vehicle, away from the fuel filler
neck, nozzle or other petrol
source, with your bare hand.(Continued)

Add fuel into the fuel tank
within 20 minutes after open-
ing the fuel filler door. After 20
minutes, the fuel tank may
shut off, causing fuel to over-
flow. In this case, re-press the
fuel filler door opening but-
ton.
Do not leave the fuel filler
door opened for an extended
period of time. It may dis-
charge the battery.
Close the fuel filler door after
fuelling the vehicle. If you
start the vehicle with the fuel
filler door opened, the mes-
sage, "Check fuel door", illu-
minates on the LCD display.
Avoid refuelling the vehicle
whilst charging the (high-volt-
age) hybrid battery. It may
cause a fire or an explosion
due to static electricity.

Maintenance
1. Crankcase emission controlsystem
The positive crankcase ventilation
system is employed to prevent air
pollution caused by blow-by gases
being emitted from the crankcase.
This system supplies fresh filtered air
to the crankcase through the air
intake hose. Inside the crankcase,
the fresh air mixes with blow-by
gases, which then pass through the
PCV valve into the induction system.
2. Evaporative emission controlsystem
The Evaporative Emission Control
System is designed to prevent fuel
vapours from escaping into the
atmosphere.
Canister
Fuel vapours generated inside the
fuel tank are absorbed and stored in
the onboard canister. When the
engine is running, the fuel vapours
absorbed in the canister are drawn
into the surge tank through the purge
control solenoid valve.
Purge Control Solenoid Valve
(PCSV)
The purge control solenoid valve is
controlled by the Engine Control
Module (ECM); when the engine
coolant temperature is low during
idling, the PCSV closes so that evap-
orated fuel is not taken into the
engine. After the engine warms-up
during ordinary driving, the PCSV
opens to introduce evaporated fuel to
the engine.
3. Exhaust emission control system
The Exhaust Emission Control
System is a highly effective system
which controls exhaust emissions
whilst maintaining good vehicle per-
formance.
When the engine starts or fails to
start, excessive attempts to restart
the engine may cause damage to the
emission system.
Engine exhaust
(carbon monoxide) precautions
Carbon monoxide can be present
with other exhaust fumes. If you
smell exhaust fumes of any kind in
your vehicle, drive with all the win-
dows fully open. Have your vehicle
checked and repaired immediately.
Engine exhaust gases contain
carbon monoxide (CO). Though
colourless and odourless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
on this page to avoid CO poi-
soning.
