F8
Introduction
This vehicle is equipped with an
event data recorder (EDR). Themain purpose of an EDR is to
record, in certain crash or near
crash-like situations, such as an
air bag deployment or hitting a
road obstacle, data that will assist
in understanding how a vehicle’s
systems performed. The EDR is
designed to record data related to
vehicle dynamics and safety sys-
tems for a short period of time,
typically 30 seconds or less. The
EDR in this vehicle is designed to
record such data as:
vehicle were operating;
passenger safety belts were
buckled/ fastened;
depressing the accelerator
and/or brake pedal; and,
ing. These data can help provide a bet-
ter understanding of the circum-
stances in which crashes and
injuries occur. NOTE: EDR data
are recorded by your vehicle onlyif a non-trivial crash situation
occurs; no data are recorded bythe EDR under normal driving
conditions and no personal data
(e.g., name, gender, age, and
crash location) are recorded.
However, other parties, such as
law enforcement, could combinethe EDR data with the type of per-
sonally identifying data routinely
acquired during a crash investiga-tion.
To read data recorded by an EDR,
special equipment is required, and
access to the vehicle or the EDR is
needed. In addition to the vehicle
manufacturer, other parties, such
as law enforcement, that have the
special equipment, can read the
information if they have access to
the vehicle or the EDR.

Armrest
The armrest is located in the center
of the rear seat. Use the strap in the
center of the armrest to pull it down.
Head Restraints
The vehicle's front and rear seats
have adjustable head restraints. The
head restraints provide comfort for
passengers, but more importantly
they are designed to help protectpassengers from whiplash and other
neck and spinal injuries during anaccident, especially in a rear impactcollision.
OFE038019To reduce the risk of serious
injury or death in an accident,
take the following precautions
when adjusting your headrestraints:
Always properly adjust the
head restraints for all passen-
gers BEFORE starting the
vehicle.
NEVER let anyone ride in a seat with the head restraints
removed or reversed.
WARNING
Make sure the vehicle is off,
shifted to P(Park), and the park-
ing brake is securely applied
whenever loading or unloading
cargo. Failure to take these steps
may allow the vehicle to move if
the shift lever is inadvertently
moved to another position.
WARNING
Be careful when loading
cargo through the rear pas-
senger seats to prevent dam-
age to the vehicle interior.
When cargo is loaded through
the rear passenger seats,
ensure the cargo is properly
secured to prevent it from
moving while driving.
Unsecured cargo in the pas-
senger compartment can
cause damage to the vehicle
or injury to it's occupants.
CAUTION

Safety system of your vehicle

In an angled collision, the force of
impact may direct the occupants in a
direction where the air bags would
not be able to provide any additional
benefit, and thus the sensors may
not deploy any air bags.Just before impact, drivers often
brake heavily. Such heavy braking
lowers the front portion of the vehicle
causing it to "ride" under a vehicle
with a higher ground clearance. Air
bags may not inflate in this "under-
ride" situation because deceleration
forces that are detected by sensors
may be significantly reduced by such
"underride" collisions.Front air bags may not inflate in
rollover accidents because air bag
deployment could not provide protec-
tion to the occupants.
However, side and curtain air bags
may inflate when the vehicle is rolled
over by a side impact collision.

Convenient features of your vehicle
The doors should always be
fully closed and locked while
the vehicle is in motion. If the
doors are unlocked, the risk of
being thrown from the vehiclein a crash is increased.
Do not pull the inner door handle of the driver's or pas-
senger's door while the vehi-
cle is moving.
WARNING
Do not leave children or animals
unattended in your vehicle. An
enclosed vehicle can become
extremely hot, causing death or
serious injury to unattended
children or animals who cannot
escape the vehicle. Children
might operate features of the
vehicle that could injure them,
or they could encounter other
harm, possibly from someone
gaining entry to the vehicle.
WARNING
Always secure your vehicle.
Leaving your vehicle unlocked increases the potential risk to
you or others from someone
hiding in your vehicle.
To secure your vehicle, while
depressing the brake, shift to
the P (Park) position, engage
the parking brake, and place the
POWER button in the OFF posi-
tion, close all windows, lock all
doors, and always take the key
with you.

Hood
Opening the hood
1. Park the vehicle and set the park-ing brake.
2. Pull the release lever to unlatch the hood. The hood should pop
open slightly. 3. Go to the front of the vehicle, raise
the hood slightly, push up the sec-
ondary latch (1) inside of the hood
center and lift the hood (2). After it
has been raised about halfway, it
will raise completely by itself.
Closing the hood
1. Before closing the hood, check thefollowing:
module compartment must becorrectly installed.
bustible material must be
removed from the fuel cell power
module compartment.
2. Lower the hood halfway (lifted approximately 30 cm (12 inches)from the closed position) and push
down to securely lock in place.
Then double check to be sure the
hood is secure. If the hood can be
raised slightly, it is not securely
locked. Open it again and close it
with more force.

This warning light illuminates:
When the POWER button is in the ON position.
- It illuminates for approximately 3seconds.
- It remains on if the parking brake is applied.
When the parking brake is applied.
When the brake fluid level in the reservoir is low.
- If the warning light illuminateswith the parking brake released, it
indicates the brake fluid level in
reservoir is low.
If the brake fluid level in the reser-
voir is low:
1. Drive carefully to the nearest safe location and stop your vehicle.
2. With the vehicle turned off, check the brake fluid level immediately and add fluid as required (For more
details, refer to "Brake Fluid" in
chapter 7) . After adding brake fluid,
check all brake components for fluid
leaks. If a brake fluid leak is found,
or if the warning light remains on, or
if the brakes do not operate proper-
ly, do not drive the vehicle. Have the
vehicle inspected by an authorized
HYUNDAI dealer.
Dual-diagonal braking system
Your vehicle is equipped with dual-
diagonal braking systems. This
means you still have braking on two
wheels even if one of the dual sys-
tems should fail. With only one of the dual systems
working, more than normal pedal
travel and greater pedal pressure is
required to stop the vehicle. Also, the vehicle will not stop in as
short a distance with only a portion
of the brake system working.
