Safety features of your vehicle
50 3SRS warning light
The SRS (Supplement Restraint
System) air bag warning light on the
instrument panel displays the air bag
symbol depicted in the illustration. The
system checks the air bag electrical
system for malfunctions. The light indi-
cates that there is a potential problem
with your air bag system.During a moderate to severe frontal
collision, sensors will detect the vehi-
cle’s rapid deceleration. If the rate of
deceleration is high enough, the con-
trol unit will inflate the front air bags.
The front air bags help protect the
driver and front passenger by
responding to frontal impacts in
which seat belts alone cannot provide
adequate restraint.
• Air bags are activated (able to
inflate if necessary) only when the
ignition switch is in the ON position.
• Air bags inflate in the event of a
severe frontal or side collision to
help protect the occupants from
serious physical injury.
• There is no single speed at which
the air bags will inflate. Generally,
air bags are designed to inflate
based upon the severity of a colli-
sion and its direction. These two
factors determine whether the sen-
sors produce an electronic deploy-
ment/inflation signal.
WARNING
If your SRS malfunctions, the
air bag may not inflate properly
during an accident increasing
the risk of serious injury or
death.
If any of the following condi-
tions occur, your SRS is mal-
functioning:
•The light does not turn on for
approximately six seconds
when the ignition switch is
placed in the ON position.
•The light stays on after illumi-
nating for approximately six
seconds.
•The light comes on while the
vehicle is in motion.
•The light blinks when the
engine is running.
Have an authorized HYUNDAI
dealer inspect the SRS as soon
as possible if any of these con-
ditions occur.

This system helps to protect your
vehicle and valuables. The horn will
sound and the hazard warning lights
will blink continuously if any of the
following occurs:
- A door is opened without using the
remote key or smart key.
- The trunk is opened without using
the remote key or smart key.
- The engine hood is opened.
The alarm continues for 30 seconds,
then the system resets. To turn off
the alarm, unlock the doors with the

Features of your vehicle
✽NOTICE
• Make sure to refuel your
vehicle according to the "Fuel
Requirements" suggested in chap-
ter 1.
• Do not spill fuel on the exterior
surfaces of the vehicle. Any type of
fuel spilled on painted surfaces
may damage the paint.(Continued)
• When refueling, always move
the shift lever to the P (Park)
position (for automatic
transaxle) or first gear or R
(Reverse, for manual transaxle),
set the parking brake, and place
the ignition switch to the
LOCK/OFF position. Sparks
produced by electrical compo-
nents related to the engine can
ignite fuel vapors causing a fire.
• Do not use matches or a
lighter and do not smoke or
leave a lit cigarette in your
vehicle while at a gas station,
especially during refueling.
• Do not over-fill or top-off your
vehicle tank, which can cause
gasoline spillage.
(Continued)(Continued)
• If a fire breaks out during refu-
eling, leave the vicinity of the
vehicle, and immediately con-
tact the manager of the gas
station and then contact the
local fire department. Follow
any safety instructions they
provide.
• If pressurized fuel sprays out,
it can cover your clothes or
skin and thus subject you to
the risk of fire and burns.
Always remove the fuel cap
carefully and slowly. If the cap
is venting fuel or if you hear a
hissing sound, wait until the
condition stops before com-
pletely removing the cap.
• Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
CAUTION
If the fuel filler cap requires
replacement, use only a genuine
HYUNDAI cap or the equivalent
specified for your vehicle. An
incorrect fuel filler cap can
result in a serious malfunction
of the fuel system or emission
control system.

Electric power steering (EPS)
The system assists you with steering
the vehicle. If the engine is off or if
the power steering system becomes
inoperative, the vehicle may still be
steered, but it will require increased
steering effort.
Also, the steering effort becomes
heavier as the vehicle’s speed
increases and becomes lighter as
the vehicle’s speed decreases for
better control of the steering wheel.
Should you notice any change in the
effort required to steer during normal
vehicle operation, we recommend
that the system be checked by an
authorized HYUNDAI dealer.
✽NOTICE
The following symptoms may occur
during normal vehicle operation:
• The steering effort may be high
immediately after placing the igni-
tion switch in the ON position.
This happens as the system per-
forms the EPS system diagnostics.
When the diagnostics is complet-
ed, the steering wheel will return
to its normal condition.
• A click noise may be heard from
the EPS relay after the ignition
switch is placed to the ON or
LOCK/OFF position.
• A motor noise may be heard when
the vehicle is at stop or at a low
driving speed.
• When you operate the steering
wheel in low temperature, abnor-
mal noise may occur. If tempera-
ture rises, the noise will disappear.
This is a normal condition.
STEERING WHEEL
CAUTION
If the Electric Power Steering
System does not operate nor-
mally, the warning light ( ) will
illuminate on the instrument
cluster. The steering wheel may
become difficult to control or
operate. Take your vehicle to an
authorized HYUNDAI dealer and
have the system checked as
soon as possible.

Features of your vehicle
Parking Brake & Brake
Fluid Warning Light
This warning light illuminates:
• Once you set the ignition switch or
Engine Start/Stop Button to the ON
position.
- It illuminates for approximately 3
seconds
- 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 illuminates
with the parking brake released, it
indicates the brake fluid level is
low.
If the brake fluid level in the reservoir
is low:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. With the engine stopped, check the
brake fluid level immediately and add
fluid as required (For more details,
refer to “Brake Fluid” in chapter 7).Then check all brake components
for fluid leaks. If any leak on the
brake system is found, the warning
light remains on, or the brakes do
not operate properly, do not drive
the vehicle.
In this case, have your vehicle
towed to an authorized HYUNDAI
dealer and inspected.
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 are
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.
If the brakes fail while you are driv-
ing, shift to a lower gear for addition-
al engine braking and stop the vehi-
cle as soon as it is safe to do so.
WARNING - Parking
Brake & Brake Fluid
Warning Light
Driving the vehicle with a warn-
ing light ON is dangerous. If the
Parking Brake & Brake Fluid
Warning Light illuminates with
the parking brake released, it
indicates that the brake fluid
level is low.
In this case, have your vehicle
inspected by an authorized
HYUNDAI dealer.

inspected by an authorized
HYUNDAI dealer as soon as pos-
sible.
Engine Coolant
Temperature Warning
Light (if equipped)
This warning light illuminates:
• When the engine coolant tempera-
ture is above 120°C (248°F). This
means that the engine is overheat-
ed and may be damaged.
If your vehicle is overheated, refer
to “Overheating” in chapter 6.
CAUTION - Engine
Overheating
Do not continue driving with the
engine overheated. Otherwise
engine may be damaged.
