RECOMMENDED LUBRICANTS AND CAPACITIES
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.

*1 : Refer to the recommended SAE viscosity numbers on page 12.
*2 : Engine oils labeled Energy Conserving Oil are now available. Along with other additional
benefits, they contribute to fuel economy by reducing the amount of fuel necessary
to overcome engine friction. Often, these improvements are difficult to measure in
everyday driving, but in a year’s time, they can offer significant cost and energy savings.
*3 : If the recommended engine oil is not available in your country, you are able to use API
SL/ILSAC GF-3 or ACEA A3.
*4 : To maintain the best braking performance and ABS/ESC performance, we recommend
that you use genuine brake fluid that conform to specifications. (Standard : SAE J1704
DOT-4 LV, ISO4925 CLASS-6 and FMVSS 116 DOT-4)

Seats & Safety System
Do Not Install a Child Restraint in the
Front Passenger’s Seat
OHI039193NOHI039193N
Even though your vehicle is equipped
with the OCS, never install a child
restraint in the front passenger’s seat.
An inflating air bag can forcefully strike a
child or child restraint resulting in serious
or fatal injury.
WARNING
•
NEVER place a rear-facing or front-
facing child restraint in the front
passenger’s seat of the vehicle.
• An inflating frontal air bag could
forcefully strike a child resulting in
serious injury or death.
• Always properly restrain children in
an appropriate child restraint in the
rear seat of the vehicle.
Why Didn’t My Air Bag Go Off in
a Collision?
Air bags are not designed to inflate in
every collision. There are certain types
of accidents in which the air bag would
not be expected to provide additional
protection. These include rear impacts,
second or third collisions in multiple
impact accidents, as well as low speed
impacts. Damage to the vehicle indicates
a collision energy absorption, and is not
an indicator of whether or not an air bag
should have inflated.
WARNING
To reduce the risk of an air bag
deploying unexpectedly and causing
serious injury or death:
• Do not hit or allow any objects to
impact the locations where air bags
or sensors are installed.
• Do not perform maintenance on or
around the air bag sensors. If the
location or angle of the sensors is
altered, the air bags may deploy
when they should not or may not
deploy when they should.
• Do not install bumper guards or
replace the bumper with a non-
genuine HYUNDAI parts. This may
adversely affect the collision and air
bag deployment performance.
• Place the ignition switch in the
LOCK/OFF or ACC position when the
vehicle is being towed to prevent
inadvertent air bag deployment.
• Have all air bag repairs conducted by
an authorized HYUNDAI dealer.

Seats & Safety System3-56
ODN8A039088ODN8A039088
Front air bags may not inflate in rollover
accidents because air bag deployment
may not provide protection to the
occupants.
However, side and curtain air bags may
inflate when the vehicle is rolled over by
a side impact collision.
ODN8A039055ODN8A039055
Air bags may not inflate if the vehicle
collides with objects such as utility poles
or trees, where the point of impact is
concentrated and the collision energy is
absorbed by the vehicle structure.
SRS Care
The SRS is virtually maintenance-free
and there are no parts you can safely
service by yourself. If the SRS air bag
warning light does not illuminate when
the ignition switch is in the ON position,
or continuously remains on, have your
vehicle immediately inspected by an
authorized HYUNDAI dealer.
Any work on the SRS system, such as
removing, installing, repairing, or any
work on the steering wheel, the front
passenger’s panel, front seats and roof
rails must be performed by an authorized
HYUNDAI dealer. Improper handling of
the SRS system may result in serious
personal injury.
WARNING
To reduce the risk of serious injury or
death, take the following precautions:
• Do not attempt to modify or
disconnect the SRS components or
wiring, including the addition of any
kind of badges to the pad covers or
modifications to the body structure.
• Do not place objects over or near
the air bag modules on the steering
wheel, instrument panel, or the front
passenger’s panel above the glove box.
• Clean the air bag pad covers with
a soft cloth moistened with plain
water. Solvents or cleaners could
adversely affect the air bag covers
and proper deployment of the
system.
• Always have inflated air bags
replaced by an authorized HYUNDAI
dealer.
• If components of the air bag system
must be discarded, or if the vehicle
must be scrapped, certain safety
precautions must be observed.
Consult an authorized HYUNDAI
dealer for the necessary information.
Failure to follow these precautions
could increase the risk of personal
injury.

Convenient Features5-98
The following objects may not be
recognized by the sensor:
• Sharp or slim objects such as ropes, chains or small poles.
• Objects, which tend to absorb sensor frequency such as clothes, spongy
material or snow.
• Undetectable objects smaller than 40 in (100 cm) and narrower than 6 in (14
cm) in diameter.
WARNING
Your new vehicle warranty does not
cover any accidents or damage to the
vehicle or injuries to its occupants
related to Reverse Parking Distance
Warning system. Always drive safely
and cautiously.
Reverse Parking Distance
Warning System Precautions
• Reverse Parking Distance Warning system may not sound consistently
depending on the speed and shapes
of the objects detected.
• Reverse Parking Distance Warning system may malfunction if the vehicle
bumper height or sensor installation
has been modified or damaged. Any
non-factory installed equipment or
accessories may also interfere with
the sensor performance.
• The sensor may not recognize objects less than 12 in (30 cm) from the
sensor, or it may sense an incorrect
distance. Use caution.
• When the sensor is frozen or stained with snow, dirt, or water, the sensor
may be inoperative until the stains are
removed using a soft cloth.
• Do not push, scratch or strike the sensor with any hard objects that
could damage the surface of the
sensor. Sensor damage could occur.
• Do not spray the sensors or its surrounding area directly with a high
pressure washer. Shock applied from
high pressure water may cause the
device to not operate normally.

Convenient Features5-102
