To help achieve proper engine and powertrain performance and durability, use only
lubricants of the proper quality. The correct lubricants also help promote engine
efficiency that results in improved fuel economy.
These lubricants and fluids are recommended for use in your vehicle.

CAUTION
Always be sure to clean the area around
any filler plug, drain plug, or dipstick
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.

If you believe that your vehicle has a defect which could cause a crash or could cause
injury or death, you should immediately inform Transport Canada (TC) in addition to
notifying HYUNDAI AUTO CANADA CORP.
Mailing Address:
Transport Canada - ASFAD

This chapter provides you with important information about how to protect yourself and your
passengers. It explains how to properly use your seats and seat belts, and how your air bags work.
Additionally, this chapter explains how to properly restrain infants and children in your vehicle.

Seats & Safety System
3-2
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. 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
While 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 shorter 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 cellular 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 or getting
into 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 when conditions
permit safe use. NEVER text or email
while 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 tire blowout or a mechanical
failure can be extremely hazardous. To
reduce the possibility of such problems,
check your tire pressures and condition
frequently, and perform all regularly
scheduled maintenance.
