Maintenance
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 con-
trolled by the Engine Control Module
(ECM); when the engine coolant temper-
ature is low during idling, the PCSV clos-
es so that evaporated 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 performance.
Vehicle modifications
This vehicle should not be modified. Modification of your vehicle could
affect its performance, safety or dura-
bility and may even violate governmen-
tal safety and emissions regulations.
In addition, damage or performance
problems resulting from any modifica-
tion may not be covered under warran-
ty.
If you use unauthorised electronic devices, it may cause the vehicle to
operate abnormally, wire damage, bat-
tery discharge and fire. For your safety,
do not use unauthorized electronic
devices.
Engine exhaust gas precautions
(carbon monoxide)
Carbon monoxide can be present with other exhaust fumes. Therefore, if you
smell exhaust fumes of any kind inside
your vehicle, have it inspected and
repaired immediately. If you ever sus-
pect exhaust fumes are coming into
your vehicle, drive it only with all the
windows fully open. Have your vehicle
checked and repaired immediately.
WARNING - Exhaust
Engine exhaust gases contain car-
bon monoxide (CO). Though
colourless and odourless, it is dan-
gerous and could be lethal if
inhaled. Follow the instructions on
this page to avoid CO poisoning.

Specifications & Consumer information
Recommended SAE viscosity
number Engine oil viscosity (thickness) has an
effect on fuel economy and cold weather
operating (engine start and engine oil
flowability). Lower viscosity engine oils
can provide better fuel economy and cold
weather performance, however, higher
viscosity engine oils are required for sat-
isfactory lubrication in hot weather. Using
oils of any viscosity other than those rec-ommended could result in engine dam-
age.When choosing an oil, consider the range
of temperature your vehicle will be oper-
ated in before the next oil change.Proceed to select the recommended oil
viscosity from the chart.
CAUTION
Always be sure to clean the area
around any filler plug, drain plug, ordipstick before checking or drain-ing any lubricant. This is especially
important in dusty or sandy areasand when the vehicle is used onunpaved roads. Cleaning the plugand dipstick areas will prevent dirt
and grit from entering the engine and other mechanisms that couldbe damaged.

*1. For better fuel economy, it is recommended to use the engine oil of a viscosity grade SAE5W-20 (API SM / ILSAC GF-4). However, if the engine oil is not available in your country,
select the proper engine oil using the engine oil viscosity chart.
