RECOMMENDED LUBRICANTS AND CAPACITIES

Safety System
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 System.
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 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
(for example, 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 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.
IMPORTANT SAFETY PRECAUTIONS

3-73
03
Do Not Install a Child Restraint in the
Front Passenger’s Seat
OHI039193N
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?
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.
Air bag collision sensors
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 Genesis part. This may
adversely affect the collision and air
bag deployment performance.

[Press the Engine Start/Stop button to
the OFF or ACC position and wait for
3 minutes, when the vehicle is being
towed to prevent inadvertent air bag
deployment.

[Have all air bag repairs performed
by an authorized retailer of Genesis
Branded products.

Safety System
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 Engine Start/Stop button is in the
ON position, or continuously remains on,
have the system immediately inspected
by an authorized retailer of Genesis
Branded products.
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 be performed by an authorized
retailer of Genesis Branded products.
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, and 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 retailer of
Genesis Branded products.

[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 retailer of
Genesis Branded products for the
necessary information. Failure to
follow these precautions could
increase the risk of personal injury.
