The SRSCM (Supplemental
Restraint System Control Module)
continually monitors all SRS compo-
nents while the ignition switch is in
the ON position to determine if a
crash impact is severe enough to
require air bag deployment or pre-
tensioner seat belt deployment.
SRS 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 elec-
trical system for malfunctions. The
light indicates that there is a potential
malfunction with your air bag system,
which could include your side and
curtain air bags used for rollover pro-
tection.
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 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.

Electric Power Steering (EPS)
The system assists you with steering
the vehicle. If the engine is turned off
or if the power steering system
becomes inoperative, you may still
steer the vehicle, but it will require
increased steering effort.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the system
checked by an authorized HYUNDAI
dealer.
Information
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 performs
the EPS system diagnostics. When
the diagnostics are completed, the
steering wheel will return to its nor-
mal condition.
• A click noise may be heard from the EPS relay after the ignition switch is
in the ON or LOCK/OFF position.
• Motor noise may be heard when the vehicle is at a stop or at a low driving
speed.
• When you operate the steering wheel in low temperature, abnormal noise
may occur. If temperature rises, the
noise will disappear. This is a normal
condition.
• When an error is detected from the EPS, the warning light will illumi-
nate on the instrument cluster and
the steering efforts may be increased.
When the following symptoms occur,
immediately drive the vehicle to a
safe area and check it.
Tilt Steering/Telescopic
Steering
Adjust the steering wheel so it points
toward your chest, not toward your
face. Make sure you can see the
instrument cluster warning lights and
gauges. After adjusting, push the
steering wheel both up and down to
be certain it is locked in position.
Always adjust the position of the
steering wheel before driving.
i
If the Electric Power Steering
System does not operate nor-
mally, the warning light ( ) will
illuminate on the instrument
cluster. You may steer the vehi-
cle, but it will require increased
steering efforts. Take your vehi-
cle to an authorized HYUNDAI
dealer and have the system
checked as soon as possible.
CAUTIONNEVER adjust the steering
wheel while driving. This may
cause loss of vehicle control
resulting in an accident.

Closing the hood
1. Before closing the hood, check thefollowing:
ment must be correctly installed.
bustible material must be
removed from the engine com-
partment.
2. Return the support rod to its clip to prevent it from rattling.
3. Lower the hood halfway (front edge approximately 12 inches (30
cm) from the bumper) before drop-
ping the hood to its locked posi-
tion. Then double check to make
sure the hood is secure. If the
hood can be raised again, it is not
securely locked. Open it again and
close it with more force.
Trunk
Opening the trunk
1. Make sure the shift lever is in P(Park).
2. Then do one of the following : located on your key fob or smart
key for more than 1 second.
for vehicles equipped with smart key :
- While all doors are unlocked, press the switch (1) inside the
trunk emblem to open the trunk
with or without the smart key on
your person.
Before closing the hood,
ensure all obstructions are
removed from around the
hood opening.
Always double check to be
sure that the hood is firmly
latched before driving away.
Check there is no hood open
warning light or message dis-
played on the instrument clus-
ter. Driving with the hood
opened may cause a total loss
of visibility, which might
result in an accident.
Do not move the vehicle with
the hood in the raised posi-
tion, as vision is obstructed,
which might result in an acci-
dent, and the hood could fall
or be damaged.

Use only approved portable
plastic fuel containers designed
to carry and store gasoline.
When refueling, always move
the shift lever to the P (Park)
position, set the parking
brake, and place the ignition
switch to the LOCK/OFF posi-
tion. Sparks produced by
electrical components 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.
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.
Do not get back into a vehicle
once you have begun refuel-
ing. You can generate a build-
up of static electricity by
touching, rubbing or sliding
against any item or fabric
capable of producing static
electricity. Static electricity
discharge can ignite fuel
vapors causing a fire. If you
must re-enter the vehicle, you
should once again eliminate
potentially dangerous static
electricity discharge by touch-
ing a metal part of the vehicle,
away from the fuel filler neck,
nozzle or other gasoline
source, with your bare hand.
When using an approved
portable fuel container, be
sure to place the container on
the ground prior to refueling.
Static electricity discharge
from the container can ignite
fuel vapors causing a fire.
Once refueling has begun,
contact between your bare
hand and the vehicle should
be maintained until the filling
is complete.
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.

If the brake fluid level in the reser-
voir is low:
1. Drive carefully to the nearest safelocation 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). After adding
brake fluid, check all brake com-
ponents for fluid leaks. If a brake
fluid leak is found, or if the warning
light remains on, or if the brakes
do not operate properly, 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.
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.
Anti-lock Brake System
(ABS) Warning Light
This warning light illuminates:
Once you set the ignition switch or
the Engine Start/Stop button to the
ON position.
- It illuminates for approximately 3seconds and then goes off.
When there is a malfunction with the ABS (The normal braking sys-
tem will still be operational without
the assistance of the anti-lock
brake system).
In this case, have your vehicle
inspected by an authorized
HYUNDAI dealer.
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.
