Features of your vehicle
A driver position memory system is pro-
vided to store and recall the driver seat,
outside rearview mirror and steering
wheel positions with a simple button
operation. By saving the desired positions
into the system memory, different drivers
can reposition the driver seat, outside
rearview mirror and steering wheel based
upon their driving preference. If the bat-
tery is disconnected, the position memo-
ry will be lost and the driving positionsshould be restored in the system.
✽✽NOTICE
If the memory system does not operate
normally, have the driver position mem-
ory system checked by an authorized
HYUNDAI dealer.
Storing positions into memory
using the buttons on the door
Storing driver’s seat positions
1. Shift the shift lever into P while the engine start/stop button is ON.
2. Adjust the driver seat, outside rearview mirror and steering wheel to
positions comfortable for the driver.
3. Press SET button on the control panel. The system will beep once.
4. Press one of the memory buttons (1 or 2) within 5 seconds after pressing the
SET button. The system will beep
twice when the memory has been suc-cessfully stored.
Recalling positions from memory
1. Shift the shift lever into P while theengine start/stop button is ON.
2. To recall the position in memory, press the desired memory button (1 or 2).
The system will beep once, then the
driver seat, outside rearview mirror
and steering wheel will automatically
adjust to the stored positions.
Adjusting one of the control knobs for the
driver seat, outside rearview mirror and
steering wheel while the system is recall-ing the stored positions will cause the
movement for that component to stop
and move in the direction that the control
knob is moved. Other components will
continue to the recalled position.
DRIVER POSITION MEMORY SYSTEM (IF EQUIPPED)WARNING
Never attempt to operate the driver
position memory system while the
vehicle is moving.
This could result in loss of control, and an accident causing death,
serious injury, or property damage.
WARNING
Use caution when recalling adjust-
ment memory while sitting in the
vehicle. Push the seat position con-
trol knob to the desired position
immediately if the seat moves too

Power steering
Power steering uses energy from the
engine to assist you in steering the vehi-
cle. 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.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the power steer-
ing checked by an authorized HYUNDAI
dealer.Electronic Hydraulic Power Steering
(EHPS)
EHPS uses an electromotor to assist you
in steering the vehicle. It senses the vehi-cle speed and road condition.
If the engine is off or if the power steer-
ing system becomes inoperative, the
vehicle may still be steered, but it will
require increased steering effort.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the power steer-
ing checked by an authorized HYUNDAI
dealer.
STEERING WHEEL
CAUTION
Never hold the steering wheel
against a stop (extreme right or left turn) for more than 5 seconds withthe engine running. Holding the
steering wheel for more than 5 sec-onds in either position may cause damage to the power steeringpump.

Low brake fluid level warning
If the warning light remains on, it may
indicate that the brake fluid level in the
reservoir is low.
If the warning light remains on:
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. Then check all brake
components for fluid leaks.
3. Do not drive the vehicle if leaks are found, the warning light remains on or
the brakes do not operate properly.
Have the vehicle towed to any author-
ized HYUNDAI dealer for a brake sys-
tem inspection and necessary repairs.
Your vehicle is equipped with dual-diago-
nal braking systems. This means you still
have braking on two wheels even if one
of the dual systems should fail. With only
one of the dual systems working, more
than normal pedal travel and greaterpedal pressure are required to stop the
car. 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 driving, shift to a lower gear
for additional engine braking and stop the
vehicle as soon as it is safe to do so. To check bulb operation, check whether
the parking brake and brake fluid warninglight illuminates when the engine
start/stop button is in the ON position.Low tire pressure
telltale (if equipped)
The low tire pressure telltale comes on
for 3 seconds after the engine start/stop
button is turned to the ON position.
If the warning light does not come on, or
continuously remains on after coming on
for about 3 seconds when you turned the
engine start/stop button to the ON posi-
tion, the Tire Pressure Monitoring
System is not working properly. If this
occurs, have your vehicle checked by an
authorized HYUNDAI dealer as soon as
possible.
These warning lights will also illuminate if
one or more of your tires are significantly
under-inflated. You should stop and
check your tires as soon as possible. If
the warning lights illuminate while driv-
ing, reduce vehicle speed immediately
and stop the vehicle. Avoid hard braking
and overcorrecting at the steering wheel.Inflate the tires to the proper pressure as
indicated on the vehicle’s tire informationplacard.
WARNING
Driving the vehicle with a warning
light on is dangerous. If the brake
warning light remains on, have the
brakes checked and repaired imme-
diately by an authorized HYUNDAI
dealer.

Features of your vehicle
Low tire pressure position indicator(if equipped)
If one or more of your tires are signifi- cantly under-inflated, this indicator indi-cates which tire is significantly under-
inflated by illuminating the correspondingposition light.
TPMS (Tire PressureMonitoring System) malfunction indicator (if equipped)
The TPMS malfunction indicator comes
on for 3 seconds after the engine
start/stop button is turned to the ON posi-
tion. If the warning light does not come
on, or continuously remains on after
coming on for about 3 seconds when you
turned the engine start/stop button to the
ON position, the Tire Pressure
Monitoring System is not working proper-
ly. If this occurs, have your vehicle
checked by an authorized HYUNDAI
dealer as soon as possible.
The warning light also comes on and
stays on when there is a problem with the
Tire Pressure Monitoring System.
If this happens, the system may not mon-
itor the tire pressure. Have the system
checked by an authorized HYUNDAI
dealer as soon as possible.
WARNING - Low tire pres-
sure
Significantly low tire pressure
makes the vehicle unstable and can
contribute to loss of vehicle controland increased braking distances.
Continued driving on low pressure
tires will cause the tires to overheatand fail.TPMS
