How does the air bags system
operate?
ONX4030055
The SRS consists of the following
components:
(1) Driver's front air bag module
(2) Passenger's front air bag module
(3) Side air bag modules
(4) Curtain air bag modules
(5) Retractor pre-tensioner
(6) Air bag warning light
(7) SRS control module (SRSCM)/
Rollover sensor
(8) Front impact sensors
(9) Side impact sensors
(10) Side pressure sensors
(11) Emergency fastening device system
(12) Occupant classification system
(13) Seat belt buckle sensor
The SRSCM continually monitors all SRS
components while the ignition switch
is ON 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 (Supplemental 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 indicates that
there is a potential problem with your
air bag system, which could include
your side and/or curtain air bags used
for rollover protection (if equipped with
rollover sensor).
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 conditions occur,
your SRS is malfunctioning:
• The light does not turn on for
approximately three to six seconds
when the Engine Start/Stop button is
in the ON position.
• The light stays on after illuminating
for approximately three to six
seconds.
• The light comes on while the vehicle
is in motion.
• The light blinks when the engine is
running.
We recommend that an authorized
HYUNDAI dealer inspect the SRS
as soon as possible if any of these
conditions occur.

Driving your vehicle

Parking brake warning light
Check the Parking Brake
warning light by pressing the
Engine Stop/Start button to the
ON position.
This light will be illuminated when the
parking brake is applied with the Engine
Stop/Start button in the START or ON
position.
Before driving, be sure the parking
brake is released and the Parking Brake
warning light is OFF.
If the Parking Brake warning light
remains on after the parking brake is
released while the engine is running,
there may be a malfunction in the
brake system. Immediate attention is
necessary.
If at all possible, cease driving the vehicle
immediately. If that is not possible,
use extreme caution while operating
the vehicle and only continue to drive
the vehicle until you can reach a safe
location.
Electronic Parking Brake (EPB)
Malfunction
If the Electronic Parking Brake (EPB) does
not release normally, DO NOT DRIVE THE
VEHICLE. Have your vehicle inspected at
an authorized HYUNDAI dealer.
It is recommended to have your vehicle
towed on a flatbed tow truck if the EPB
malfunction occurs.
Auto Hold
Auto Hold maintains the vehicle in a
standstill even though the brake pedal is
not depressed after the driver brings the
vehicle to a complete stop by depressing
the brake pedal.
To apply:
„„Type A
ONX4060008
„„Type B
ONX4E060027
1. With the driver’s door, engine hood
and liftgate (vehicle equipped with
shift button) closed, then press the
AUTO HOLD switch. The white AUTO
HOLD indicator will come on and the
system will be in the standby position.

Driving your vehicle
6-56
ONX4E060022
• Always hold the steering wheel firmly
when you are driving off-road.
WARNING
Do not grab the inside of the steering
wheel when you are driving off-road.
You may hurt your arm by a sudden
steering maneuver or from steering
wheel rebound due to an impact with
objects on the ground. You could lose
control of the steering wheel which may
lead to serious injury or death.
Emergency precautions
Tires
Do not use tire and wheel with different
size and type from the one originally
installed on your vehicle. It can affect the
safety and performance of your vehicle,
which could lead to steering failure or
rollover causing serious injury.
When replacing the tires, be sure to
equip all four tires with the tire and wheel
of the same size, type, tread, brand and
load-carrying capacity. If you equip your
vehicle with any tire/wheel combination
not recommended by HYUNDAI for off-
road driving, you should not use these
tires for highway driving.
WARNING
Never start or run the engine while a
full-time AWD vehicle is raised on a
jack. The vehicle can slip or roll off of a
jack causing serious injury or death to
you or those nearby.
Towing
AWD vehicles must be towed with
a wheel lift and dollies or flatbed
equipment with all the wheels off
the ground. For more details, refer to
"Towing" in chapter 8.
Dynamometer testing
A full-time AWD vehicle must be
tested on a special four wheel chassis
dynamometer.

Emergency situations
8-10
Tire pressure monitoring system
WARNING
Over-inflation or under-inflation can
reduce tire life, adversely affect vehicle
handling, and lead to sudden tire failure
that may cause loss of vehicle control
resulting in an accident.
Each tire, including the spare (if
provided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard
or tire inflation pressure label. (If your
vehicle has tires of a different size than
the size indicated on the vehicle placard
or tire inflation pressure label, you should
determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your tires is
significantly under-inflated. Accordingly,
when the low tire pressure telltale
illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Driving on
a significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating
properly. The TPMS malfunction
indicator is combined with the low
tire pressure telltale. When the system
detects a malfunction, the telltale will
flash for approximately one minute and
then remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be able
to detect or signal low tire pressure as
telltale. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate
tires or wheels on the vehicle that
prevent the TPMS from functioning
properly.
Always check the TPMS malfunction
telltale after replacing one or more tires
or wheels on your vehicle to ensure that
the replacement or alternate tires and
wheels allow the TPMS to continue to
function properly.
NOTICE
If any of the below happens, we
recommend that you have the system
checked by an authorized HYUNDAI
dealer.
1. The Low Tire Pressure Telltale/ TPMS
Malfunction Indicator does not
illuminate for 3 seconds when the
Engine Start/Stop button is pressed
to the ON position or when the
engine is running.
2. The TPMS Malfunction Indicator
remains illuminated after blinking for
approximately 1 minute.
3. The Low Tire Pressure Position
Telltale remains illuminated.
