ELECTRONIC CONTROLLED SUSPENSION (ECS) (IF EQUIPPED)
ECS controls the vehicle suspension
automatically to maximize passenger
comfort by using the air spring in the sus-
pension.
You can also control the vehicle suspen-
sion manually in SPORT mode, NOR-
MAL mode, or HIGH mode.
To select the SPORT mode
Push the SPORT button to select the
SPORT mode that provides a tighter sus-
pension and firmer ride. And also, it
enables you to operate the shift pattern
and steering wheel more actively. The
SPORT indicator will illuminate.The SPORT mode is used for sporty driv-
ing such as driving on winding, moun-
tainous roads or high speed driving.
Push the SPORT button again to return
to NORMAL mode that provides a softer
ride. The SPORT indicator will go off.

ECS (Electronic Controlled
Suspension) Malfunction indicator
The ECS malfunction indicator will illumi-
nate when the engine start/stop button is
turned to the ON position, but should go
off after approximately 3 seconds. If the
warning light does not come on, or con-
tinuously remains on after coming on for
about 3 seconds when you turn the
engine start/stop button to the ON posi-
tion, the ECS is not working properly.
If it comes on while driving, ECS is not
working properly.
Take your vehicle to an authorized
HYUNDAI dealer and have the system
checked.The ECS malfunction indicator may illu-
minate when the ESP indicator comes on
to indicate that the ESP is not working
properly, but it does not indicate malfunc-
tion of the ECS.
✽NOTICE
If the battery is discharged or if you
push the SPORT button or the vehicle
height control button repeatedly in
short time, the ECS malfunction indica-
tor may illuminate to protect the system.
CAUTION
If the ECS malfunction indicator
illuminates when there is no air in
the suspension, the vehicle height
will be very lower, so do not drive to
protect the vehicle from the projec-
tions on the surface of the ground.
Take your vehicle to an authorized
HYUNDAI dealer by towing the vehi-
cle and have the system checked.
You should tow the vehicle as the
picture.

Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.
Brake fluid
Check brake fluid level in the brake fluid
reservoir. The level should be between
“MIN” and “MAX” marks on the side of
the reservoir. Use only hydraulic brake

any damaged or leaking parts immedi-
ately. Inspect the power steering belt (or
drive belt) for evidence of cuts, cracks,
excessive wear, oiliness and proper ten-
sion. Replace or adjust it if necessary.
