Maintenance
Do not use strong soap, chemi-cal detergents or hot water, and
do not wash the vehicle in direct
sunlight or when the body of the
vehicle is warm.
Be careful when washing the side windows of your vehicle.
Especially, with high-pressure
water, water may leak through
the windows and wet the interi-
or.
To prevent damage to the plastic parts, do not clean with chemi-
cal solvents or strong deter-
gents.
To prevent damage to the charg- ing door, make sure to close and
lock the vehicle doors when
washing (high-pressure wash-
ing, automatic car washing, etc.)
the vehicle. Water washing in the engine
compartment including high
pressure water washing may
cause the failure of electrical cir-
cuits located in the engine com-
partment.
Never allow water or other liq- uids to come in contact with
electrical/electronic compo-
nents inside the vehicle as this
may damage them.
Waxing
A good coat of wax is a barrier
between your paint and contaminate.
Keeping a good coat of wax on your
vehicle will help protect it.
Wax the vehicle when water will no
longer bead on the paint.
Always wash and dry the vehicle
before waxing. Use a good quality
liquid or paste wax, and follow the
manufacturer’s instructions. Wax all
metal trim to protect it and to main-
tain its luster.
Removing oil, tar, and similar materi-
als with a spot remover will usually
strip the wax from the finish. Be sure
to re-wax these areas even if the rest
of the vehicle does not yet need wax-
ing.

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.

Maintenance
Do not operate the engine in con-fined or closed areas (such as
garages) any more than what is
necessary to move the vehicle in or
out of the area.
When the vehicle is stopped in an open area for more than a short
time with the engine running,
adjust the ventilation system (as
needed) to draw outside air into the
vehicle.
Never sit in a parked or stopped vehicle for any extended time with
the engine running.
When the engine stalls or fails to start, excessive attempts to restart
the engine may cause damage to
the emission control system.Operating precautions for cat-alytic converters (if equipped)Your vehicle is equipped with a cat-
alytic converter emission control
device.
To prevent damage to the catalytic
converter and to your vehicle, take
the following precautions:
Use only UNLEADED FUEL for
petrol engines.
Do not operate the vehicle when there are signs of engine malfunc-
tion, such as misfire or a noticeable
loss of performance.
Do not misuse or abuse the engine. Examples of misuse are
coasting with the hybrid system off
and descending steep grades in
gear with the hybrid system off.
Do not operate the engine at high idle speed for extended periods (5
minutes or more).
The exhaust system and cat-
alytic converter are very hot
during and immediately after
the engine has been running. To
avoid SERIOUS INJURY or
DEATH:
Do not park, idle, or drive the
vehicle over or near flamma-
ble objects, such as grass,
vegetation, paper, leaves, etc.
A hot exhaust system can
ignite flammable items under
your vehicle.
Keep away from the exhaust
system and catalytic convert-
er or you may get burned.
Also, Do not remove the heat
sink around the exhaust sys-
tem, do not seal the bottom of
the vehicle, and do not coat
the vehicle for corrosion con-
trol. It may present a fire risk
under certain conditions.
