before checking or draining any lubricant. This is especially important in dusty or
sandy areas and when the vehicle is used on unpaved roads. Cleaning the plug
and dipstick areas will prevent dirt and grit from entering the engine and other
mechanisms that could be damaged.
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 satisfactory lubrication in hot weather. Using oils
of any viscosity other than those recommended could result in engine damage.
When choosing an oil, consider the range of temperature your vehicle will be
operated in before the next oil change.
Proceed to select the recommended oil viscosity from the chart.

IMPORTANT SAFETY PRECAUTIONS
You will find many safety precautions
and recommendations throughout this
section, and throughout this manual.
The safety precautions in this section are
among the most important.
Always wear your seat belt
A seat belt is your best protection in all
types of accidents. Air bags are designed
to supplement seat belts, not replace
them. So even though your vehicle is
equipped with air bags, ALWAYS make
sure you and your passengers wear your
seat belts, and wear them properly.
Restrain all children
All children under age 13 should ride
in your vehicle properly restrained in a
rear seat, not the front seat. Infants and
small children should be restrained in
an appropriate Child Restraint Systems.
Larger children should use a booster
seat with the lap/shoulder belt until they
can use the seat belt properly without a
booster seat.
Air bag hazards
Whilst air bags can save lives, they can
also cause serious or fatal injuries to
occupants who sit too close to them, or
who are not properly restrained. Infants,
young children, and short adults are at
the greatest risk of being injured by an
inflating air bag. Follow all instructions
and warnings in this manual.
Driver distraction
Driver distraction presents a serious and
potentially deadly danger, especially for
inexperienced drivers. Safety should be
the first concern when behind the wheel
and drivers need to be aware of the wide
array of potential distractions, such as
drowsiness, reaching for objects, eating,
personal grooming, other passengers,
and using mobile phones.
Drivers can become distracted when
they take their eyes and attention off
the road or their hands off the wheel to
focus on activities other than driving. To
reduce your risk of distraction and an
accident:

[ALWAYS set up your mobile devices
(i.e., MP3 players, phones, navigation
units, etc.) when your vehicle is parked
or safely stopped.

[ONLY use your mobile device when
allowed by laws and conditions permit
safe use.
NEVER text or email whilst driving.
Most countries have laws prohibiting
drivers from texting. Some countries
and cities also prohibit drivers from
using handheld phones.

[NEVER let the use of a mobile device
distract you from driving. You have a
responsibility to your passengers and
others on the road to always drive
safely, with your hands on the wheel
as well as your eyes and attention on
the road.

Control your speed
Excessive speed is a major factor in
crash injuries and deaths. Generally, the
higher the speed, the greater the risk,
but serious injuries can also occur at
lower speeds. Never drive faster than is
safe for current conditions, regardless of
the maximum speed posted.
Keep your vehicle in safe
condition
Having a tyre blowout or a mechanical
failure can be extremely hazardous. To
reduce the possibility of such problems,
check your tyre pressures and condition
frequently, and perform all regularly
scheduled maintenance.
