XML: can't have multiple elements with provided schema

I'm kinda new to XML and learning XML Schema right now. I've encountered problem where I cannot create more than one car element with provided xml schema.

Right now I have a simple schema like this: 

<?xml version="1.0" encoding="utf-8"?>
<xs:schema  xmlns:xs="http://www.w3.org/2001/XMLSchema"
            targetNamespace="http://www.cars.lt"
            xmlns="http://www.cars.lt"
            elementFormDefault="qualified"
            xmlns:carsType="http://www.cars.lt">

  <xs:element name="cars" type="carsType:CarType">
  </xs:element>

  <xs:complexType name ="CarType">
    <xs:sequence>
      <xs:element name="car" type="carsType:CarWithBrandAndModel">
        <xs:key name="carKey">
          <xs:selector xpath="car"/>
          <xs:field xpath="@id"/>
        </xs:key>
        <xs:keyref name="NoCarsRef" refer="carKey">
                    <xs:selector xpath="noCar" />
                    <xs:field xpath="@id" />
                </xs:keyref>
      </xs:element>
    </xs:sequence>
  </xs:complexType>

This schema generates only one car element when instead I need to have more than one.

And when I'm trying to create two <car> elements it gives me an error that element cars has invalid child element car in namespace http://www.cars.lt.

What I tried was inserting CarType complex type into cars element, but it gives me the same error.

The default for maxOccurs is 1. If you want your XSD to allow multiple car elements, add maxOccurs with a value greater than 1 or unbounded:

<xs:element name="car" type="carsType:CarWithBrandAndModel" maxOccurs="unbounded">
