Hyundai Sonata: Front Seats / Power adjustment

The front seat can be adjusted by using the control switches located on the outside of the seat cushion. Before driving, adjust the seat to the proper position so that you can easily control the steering wheel, foot pedals and controls on the instrument panel.

WARNING

NEVER allow children in the vehicle unattended. The power seats are operable when the engine is turned off.

NOTICE

To prevent damage to the seats:

Forward and rearward adjustment

To move the seat forward or rearward:

1. Push the control switch forward or rearward.

2. Release the switch once the seat reaches the desired position.

Seatback angle

To recline the seatback:

1. Push the control switch forward or rearward.

2. Release the switch once the seatback reaches the desired position.

Reclining seatback

Sitting in a reclined position when the vehicle is in motion can be dangerous. Even when buckled up, the protections of your restraint system (seat belts and air bags) is greatly reduced by reclining your seatback.

WARNING

NEVER ride with a reclined seatback when the vehicle is moving.

Riding with a reclined seatback increases your chance of serious or fatal injuries in the event of a collision or sudden stop.

Driver and passengers should ALWAYS sit well back in their seats, properly belted, and with the seatbacks upright.

Seat belts must be snug against your hips and chest to work properly. When the seatback is reclined, the shoulder belt cannot do its job because it will not be snug against your chest. Instead, it will be in front of you. During an accident, you could be thrown into the seat belt, causing neck or other injuries.

The more the seatback is reclined, the greater chance the passenger's hips will slide under the lap belt or the passenger's neck will strike the shoulder belt.

Seat cushion height

To change the height of the seat cushion:

1. Pull the front portion of the control switch up to raise or push down to lower the front part of the seat cushion. Pull the rear portion of the control switch up to raise or push down to lower the seat cushion.

2. Release the switch once the seat reaches the desired position.

Lumbar support (for driver's seat, if equipped)

To adjust the lumbar support:

1. Press the front portion of the switch to increase support or the rear portion of the switch to decrease support.

2. Release the switch once it reaches the desired position.

Lumbar support (for driver's seat, if equipped)

The lumbar support can be adjusted by pressing the lumbar support switch.

According to the equipped feature, the lumbar support does not operate up or down when the lumbar support is in the rearmost position.

In this case, to use the system, slightly increase support by pushing the front portion of the switch (1).
